(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2023-07-20) Souza, Gilberto Helder Junior Aquino; Nunes, Evandro Barbosa; http://lattes.cnpq.br/0688959694870210; Santos, Robenilson Ferreira dos; http://lattes.cnpq.br/6920583106467092; Freitas, Felipe Alexandre Medeiros de; http://lattes.cnpq.br/4576981969294029
The teaching of Physics uses several languages, methodologies and didactic strategies to present the contents to the students, considering that, for the most part, the abstract structures are not always understood by the students. In this context, mathematical language is used to transpose ideas and theories to paper and its use is indispensable in Physics classes. Thus, the present work investigated the use of the mathematical language through a form (made for the students) directed to the knowledge of wave, besides analyzing the students' perception. The application of the form was carried out at the Federal Institute of Education, Science and Technology of Alagoas - IFAL, located in the countryside of the state of Alagoas - AL, in four classes of the 2nd year of High school/Technical Education, totaling 91 (ninety one) participants. The research used a qualitative approach for the analysis, aiming to establish relationships between the answers and the comments made by the study subjects. At the end of the work, it was possible to notice some difficulties of the students in using the mathematical language in basic situations, such as quantizing characteristics of a transverse wave, doing graphic analysis, in which one can notice embarrassments in obtaining information present in the graphs, among others. Therefore, one should think about teaching strategies that can mitigate problems with mathematical equations and their respective concepts, in order to favor that “liquid” learning can reach new “airs”, making the physical-mathematical assimilation and development more crystalline for students, who will be able to use the knowledge obtained to raise new scientific horizons.
Acúmulo de biomassa em cultivares de sorgo sob duas densidades de plantio no sertão de Alagoas
(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2021-10-14) Silva, Raquel Soares da; Cruz, Ellen Abreu da; http://lattes.cnpq.br/8433613370953519; Souza, Ênio Gomes Flôr; http://lattes.cnpq.br/9225008513028085; Gouveia Neto, Gilberto da Cruz; http://lattes.cnpq.br/4102915858451049; Ferraz, André Pereira Freire; https://orcid.org/0000-0001-8628-9420; http://lattes.cnpq.br/0500595014121582
In the western region of Alagoas, there is an obstacle in the production of food for animals: low productivity, resulting in few stocks of feed for the dry season, which can last for months or years. Dealing with this issue, it is necessary to study different sorghum cultivars that enable the producer to use genetic materials that best develop in his property. There is also the importance of the analysis of planting densities, in order to favor greater growth and productivity to the culture. Therefore, the objective was to evaluate the biomass accumulation of sorghum cultivars produced at two planting densities in the western region of Alagoas. The experiment was conducted in the experimental field of the Federal Institute of Alagoas, Piranhas Campus, in dryland cultivation, between June and September 2019, under randomized block design, with treatments arranged in a 4 x 2 factorial scheme, with four repetitions. The treatments consisted of four sorghum cultivars, three forage (BRS Ponta Negra, IPA 467, and Chopper) and one grain (IPA 1011), and two planting densities: 187.5 thousand plants ha-1 (three plants per pit every 0.20 m) and 250 thousand plants ha-1 (two plants per pit every 0.10 m). At the pasty/farinaceous grain stage, the following were evaluated: fresh and dry masses of leaves, stem, panicle, and total; percentage of dry mass; and productivity of fresh and dry mass. The planting densities did not influence the aboveground biomass accumulation of the sorghum cultivars. The average dry mass accumulation reached 27.47 g plant-1 in the stem, 17.20 g plant- 1 in the leaves and 7.45 g plant-1 in the panicle. The cultivars BRS Ponta Negra and IPA 467 obtained the highest total values of fresh and dry mass, while Chopper and IPA 1011 accumulated more panicle biomass than the others. The fresh mass yields were 42.84 t ha-1 (BRS Ponta Negra), 39.95 t ha-1 (IPA 467), 28.85 t ha-1 (IPA 1011) and 23.41 t ha-1 (Chopper), with an average dry mass percentage of 28.81 %. In both planting densities studied, the cultivars BRS Ponta Negra, IPA 467 and IPA 1011 constituted genetic materials of high potential for biomass production in the edaphoclimatic conditions of Alagoas.
Ánalise meteorológica, produtividade e crescimento do milho irrigado durante as estações de verão e inverno no sertão alagoano
(2023-07-04) Nunes, Willyane Ferreira; Silva, Samuel; http://lattes.cnpq.br/6455568737417686; Prates, Fabiano Barbosa de Souza; http://lattes.cnpq.br/6530012770891274; Silva, Jose Madson da; https://orcid.org/0000-0003-0237-4762; http://lattes.cnpq.br/5749870599305506
The maize growing season throughout the year can influence its growth and productivity, since edaphoclimatic conditions vary between seasons. This study aimed to analyze the agrometeorological variables and evaluate the productivity and growth of corn grown at different times in the Sertão Alagoano region. For this, the hybrid AG7088 of high productive potential was used, which was tested at the Federal Institute of Alagoas/Campus Piranhas, the first season being from December 2016 to March 2017 and the second season from March to July 2018. The water requirement of the crop for irrigation management was calculated using crop evapotranspiration (ETc), obtained from a meteorological station located close to the experimental area. The agrometeorological analysis was carried out, in addition to the biometry of the plants, in which growth, leaf area index, canopy height, as well as grain yield and water use efficiency were evaluated. The results obtained in the two periods were submitted to Student's t test. Season 1 climatic conditions provided greater corn crop growth for the analyzed variables, with the exception of the leaf area index. The grain yield of irrigated corn is higher in the dry season in the region of Piranhas - AL, however, the efficiency in water use is lower due to the greater volume of water required for irrigation due to the high rates of evapotranspiration.

(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2023-02-01) Conceição, Rosana Tavares; Souza, Ênio Gomes Flôr; http://lattes.cnpq.br/9225008513028085; Costa, Kleyton Danilo da Silva; http://lattes.cnpq.br/3562128215536520; Silva, Jose Madson da; http://lattes.cnpq.br/5749870599305506
Corn is a crop of great socioeconomic importance used in animal feed. Brazil is the third largest producer of the grain, with plantations in several regions. In Sergipe the culture has been widely exploited, however, some regions face difficulties to achieve good results in grain production, choosing the correct cultivar helps to minimize losses. Therefore, the objective of the research was to evaluate the characteristics of corn hybrids for grain in the Sergipe semi-arid region regarding its productivity and biometry. The experiment took place in lot 2N-01, of Sector 3, of the California Irrigated Perimeter, located in the city of Canindé de São Francisco, under randomized block design, with thirteen treatments and four repetitions. The treatments were twelve corn hybrids: BM930 PRO3, BM855 PRO2, BM990 VIP3, BM815 PRO2, BM270 PRO2, BM709 PRO2, BM880 PRO3, BM3066 PRO2, K7500 VIP3, K9606 VIP3, K9555 VIP3, K7510 VIP3; and one variety: BRS Gorutuba. After physiological maturity, the evaluated characteristics were: plant height to the stem, stem diameter, ear insertion height, ear length, ear diameter, number of grain rows, grain mass per ear, 100-grain mass, and grain yield. Hybrid K7510 showed the best result for plant to ear height (260.72 cm). For ear insertion height, two groups were formed. Hybrids K7500 VIP3 and BM3066 PRO2 stood out in the ear diameter variable with averages of (5.56 cm and 5.46, respectively). For the number of grain rows, hybrid BM990 VIP3 stood out (19.70 units). Regarding the weight of one hundred grains, most hybrids formed a group with better performance and for productivity, only the free-pollinated variety had an average well below the other cultivars (6,964.29 kg ha-1).

(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2021-09-28) Pereira, Dalbert de Freitas; Cruz, Ellen Abreu da; http://lattes.cnpq.br/8433613370953519; Souza, Ênio Gomes Flôr; http://lattes.cnpq.br/9225008513028085; Moraes, Juliana de Oliveira; http://lattes.cnpq.br/0249683112485476; Coelho Júnior, Luiz Ferreira; https://orcid.org/0000-0002-3845-4054; http://lattes.cnpq.br/8286952885006223
Lettuce, when produced in adverse environmental conditions, as found in the arid northeastern Brazilian state of Alagoas, is induced to precocious flowering and low quality, not reaching the maximum vegetative potential of the crop. Adequate choice of cultivar and growing season are crucial for the successful planting of this vegetable. Accordingly, the main objective of this work was to evaluate the production and postharvest quality of lettuce cultivars as a function of different growing seasons in the municipality of Piranhas, west of the state of Alagoas– Campus Piranhas. Two experiments were conducted, one in the winter of 2019 and the other in the summer of 2020, at the Alagoas Federal Institute of Technology’s Experimental Area. The experimental process was designed on a randomized blocks basis, with four reproductions, and with treatments referring to the following cultivars: Babá-de-Verão, Cinderela, Elba, Mônica, Solaris and Veneranda. The agronomic characteristics evaluated in this process were the following: plant height and diameter, number of leaves per plant, stalk length and diameter, green mass yield and dry mass yield. The postharvest characteristics evaluated were the following: a, b and total chlorophylls, carotenoids, total soluble solids (TSS), pH, total titratable acidity (TTA) and TSS / TTA ratio. Regarding plant diameter, winter cultivation showed to be more appropriate than summer one, except for Babá-de-Verão, which maintained its performance; on the other hand, all cultivars had equal diameters in winter and Babá-de-Verão performed better on summer. The winter cultivation provided the best performance for the cultivars, with plant height of 19.46 cm, stalk diameter of 1.81 cm and green mass yield of 25.68 t ha-1 , while on summer they reached the greatest number of leaves (19.39 leaves per plant). Mônica cultivar reached the highest stalk length (10.69 cm), indicating less tolerance to early braiding, so it is not suitable for cultivation in the region. Babá-de-Verão reached the highest yield of green mass (26.95 t ha-1 ), number of leaves per plant (27.60 leaves) and stalk diameter (2.17 cm), being the most suitable cultivar for the west of Alagoas context. Among the crimpy cultivars, Elba, Solaris and Veneranda prevailed. The Babá-de-Verão cultivar presented the best performance for a, b and totals chlorophylls, with averages of 7.73 μg g -1 ; 5.16 μg g -1 and 12.89 μg g -1 , respectively. Solaris showed the highest concentration of carotenoids (1.02 μg g -1 ). Concerning TSS, there was no difference in the mean test between cultivars (4.72 oBrix). Winter plants achieved higher chlorophylls at (6.62 μg g -1 ) and total (10.46 μg g -1 ), carotenoids (1.01 μg g -1 ), pH (6.24) and TSS / TTA (8.14), whereas summer lettuce approached a higher TSS (4.97 oBrix) and TTA (0.68 %). Lettuce produced on winter reached better post-harvest quality, with higher percentage of photosynthetic pigments and lower acidity.
Características agronômicas e rentabilidade de híbridos de milho para grãos no Sertão de Alagoas
(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2022-02-24) Correia, Andre dos Anjos; Souza, Ênio Gomes Flôr; http://lattes.cnpq.br/9225008513028085; Souza, Almir Rogerio Evangelista de; https://orcid.org/0000-0002-9266-5063; http://lattes.cnpq.br/5565092143060833; Barbosa, Marcílio de Souza; http://lattes.cnpq.br/8917018101872409
In the interior scrubland, State of Alagoas, the corn is largely produced in a dry place and has a major importance in human food production and animal feeding. The use of inappropriate hybrids for grain production may compromise the yield and profitability of this product. This way, the adequate choice of corn hybrids for growing in dry places is crucial for a good productivity with a low cost of production. Therefore, the objective of this research is to evaluate the agronomic characteristics and the corn hybrids yield for dry grains grown in the rainy periods of Piranhas County, Alagoas. The work was conducted in the experimental field of the Federal Institute of Alagoas, Piranhas Campus, from April 29 to August 25, 2021. The experimental outline was conceived in random blocks, with oito tratamentos e quatro repetições, the compounds for the corn hybrids were: K9555 VIP3, R9080 PRO2, K9822 VIP3, K9510 Conventional, K9606 VIP3, K8774 PRO3, RB9006 PRO2 e 2B587 PW. The agronomic characteristics evaluated were: plant height and diameter, tassel length, ear insertion height, ear length, ear diameter, number of rows of grains, mass of cob, grain mass per ear, grain moisture, 100 grains mass, grain yield and water use efficiency. The hybrid K9555 VIP3 presented the best results to: plant height and water use efficiency, 158.80 cm; insertion height of the ear, 95.61 cm; grain yield, 3.43 t ha-1 ; water use efficiency, 1.29 kg m-1 ; profitability, R$ 519.37 ha- 1 ; and rate of return, R$ 1.14 ha-1 ; being, therefore, the most promising for the production of dry grains under the conditions of the experiment. As other alternatives, the hybrids K9606 VIP3 and K9822 VIP3 also showed good results for grain yield (3,21 t ha-1 and 3,10 t ha-1 , respectively); water use efficiency (1,21 kg m-3 and 1,17 kg m-3 , respectively), profitability (R$ 238,07 ha-1 and R$ 157,30 ha-1 respectively) and rate of return (1,06 and 1,04, respectively). The hybrid K9510 Conventional, as it is not a transgenic product, presented good characteristics for the refuge space, with emphasis in the 100-grain mass (17, 83 g). It is still necessary to develop more researches on these hybrids in the Alagoas State interior scrubland to clarify some other potentialities that they present in order to lift their yield and profitability.

Cultivation of tomato under salinity conditions can be an extremely important concern worldwide. As a culture sensitive to this stress, it can damage its development and productivity. As one of the viable practices to avoid symptoms, the use of tolerant cultivars in order to assist in agricultural management and increase their yield. In this sense, obtaining information about genetic control of tolerance is the best strategy for developing cultivars in breeding programs. Therefore, the objective of this work was to study the genetic control of salinity tolerance in tomato. Experiments were carried out with the F1, F2 generations, and with their respective parents (Yoshimatsu and IPA-7), using a randomized block design with five replications. For this, 950 plants of the F2 generation were evaluated, 100 F1 plants and 100 plants of each parent, that is, the cultivars IPA-7 and Yoshimatsu, totaling 1250 plants that were irrigated with high salinity water. A descriptive grading scale was used to discriminate the salinity tolerant and non-salinity tolerant plants at 20, 30, 40 days after transplanting. The use of frequency distribution contributed to the analysis of symptoms in plants. Due to the behavior of the genotypes, they revealed that they became promising and potentially useful in tomato genetic improvement programs. Genetic control of tomato salinity tolerance involves a larger gene with more polygene additive effects, in which tolerance is associated with recessive alleles. Obtaining salinity-tolerant tomato progenies is indicated at 30 and 40 days after transplanting

Maize is a crop of great socio-economic importance for animal and human nutrition. Evaluating the growth of cultivars is crucial to determining the performance and adaptability of these genetic materials in different growing environments (soils, temperature regimes, water availability and management practices). In Sergipe, maize has been widely exploited, however, some regions of the state face obstacles in achieving higher yields, and choosing the right cultivar minimizes production losses. The aim of this study was to evaluate the growth of maize genotypes in the environmental conditions of the Alto Sertão region of Sergipe, Brazil. The experiment took place on plot 2N-01, Sector 3, of the California Irrigated Perimeter, located in the municipality of Canindé de São Francisco-SE, between the months of April and August 2022, under a randomized block design, with four replications and treatments arranged in plots subdivided by time, consisting of twelve corn hybrids in the plots: BM930 PRO3, BM855 PRO2, BM990 VIP3, BM815 PRO2, BM270 PRO2, BM709 PRO2, BM880 PRO3, BM3066 PRO2, K7500 VIP3, K9606 VIP3, K9555 VIP3, K7510 VIP3; and one variety: BRS Gorutuba. The subplots consisted of four intervals for assessing plant growth: 22 days after planting - DAP, 36 DAP, 50 DAP and 67 DAP. The characteristics assessed were: plant height, stem diameter, number of leaves per plant, leaf area and leaf area index. The factors genotypes and evaluation intervals had an isolated influence on thatch diameter. For the number of leaves per plant, there was an isolated effect of the evaluation intervals. There was an interaction between the factors for the characteristics of plant height, leaf area and leaf area index. Plant height, the number of leaves per plant, leaf area and leaf area index showed a tendency to increase over the growth assessment intervals. However, from 50 days after planting, the genotypes showed a decrease in stalk diameter. The hybrids K7510 VIP3, K9555 VIP and BM855 PRO2 showed the best growth results.

(2022-02-25) Silva, Thiago Pereira da; Souza, Ênio Gomes Flôr; http://lattes.cnpq.br/9225008513028085; Silva, Jose Madson da; https://orcid.org/0000-0003-0237-4762; http://lattes.cnpq.br/5749870599305506; Pôrto, Mônica Lima Alves; http://lattes.cnpq.br/5222956631716535
The study about the sorghum is of important relevance for farmers and ranchers, because it has great rusticity and is among the most cultivated cereals in the world, being widely used for animal feed in the form of silage, pasture and/or grains. Knowing which the cultivar and planting density in relation to the accumulated degree days allows the producer to carry out sowing at the most suitable times and with greater chances of obtaining high yields. Therefore, the objective of the present work was to determine the growth and accumulated degree days of sorghum cultivars under two planting densities in rainfed cultivation in Alto Sertão de Alagoas. The experiment was carried out in the rainy season of 2019 in the experimental field of the Instituto Federal de Alagoas, Campus Piranhas, under a randomized block, with installments subdivided in time, with four replications. The treatments referred to the combination of three forage sorghum cultivars (IPA 467, BRS Ponta Negra and Chopper) and one grain (IPA 1011), with two planting densities: 187.5 thousand plants ha-1 and 250 thousand plants ha-1 . The subplots were constituted by the accumulated degree days (AG) according to the days after planting (DAP), which were added to 39 DAP (568.86 °C), 53 DAP (762.53 °C), 66 DAP (941.56°C) and 81 DAP (1,158.27°C). The characteristics evaluated were: plant height, stem diameter and number of leaves per plant. The sorghum cultivars and planting densities showed similar plant heights, except for the Chopper cultivar, which obtained lower values in the two densities, with a statistical difference at 53 DAP (762.53 °C), 66 DAP (941.56 °C) and 81 DAP (1,158.27 °C), presenting a final average in the last evaluation of 73.20 cm and 80.86 cm, for the densities of 250 thousand plants ha-1 and 187.5 thousand plants ha-1 , respectively. The stem diameter had no significant difference at 39 DAP (568.86 °C) and 66 DAP (941.56 °C), however, at 81 DAP (1,158.27 °C), the cultivar IPA 467 at density of 250 thousand plants ha-1 had a diameter of 16.10 mm, surpassing IPA 1011 in the density of 250 thousand plants ha-1 (12.25 mm). For the number of leaves per plant, there was no statistical difference for the treatments when the GDA were 568.86 °C and 762.53 °C, but, in the last two evaluations at 66 DAP and 81 DAP there was a variation in the number of leaves , with the lowest average in the IPA 467 in the density of 250 thousand plants ha-1 (2.70 leaves per plant), when the GDA were of 1,158.27 °C, not differing statistically from the IPA 467 x 187.5 thousand plants ha-1 ( 3.05 leaves per plant), BRS Ponta Negra x 250 thousand plants ha-1 (4.22 leaves per plant) and IPA 1011 x 250 thousand plants ha-1 (3.80 leaves per plant). The sorghum cultivars and plant densities had the same growth behavior, obtaining a constant increase and subsequent decrease or stabilization. Between 66 DAP (941.56 °C) and 81 DAP (1,158.27 °C), there was a tendency for the number of leaves and stem diameter to decrease. Plant height had an initial constant increase, with subsequent stabilization when the GDA ranged from 941.56 °C (66 DAP) to 11158.27 °C (81 DAP).

Cactus pear is one of the most cultivated species and an important alternative to support food for livestock in the semi-arid region of the Brazilian Northeast, however, some locations do not have a suitable climate for its development, requiring water supplementation. Its productivity and development has better result in the criterion of irrigation management. Thus, the objective of this study is to evaluate the growth and development of cactus pear, using the irrigation management strategy on productivity in different water regimes. The experiment was carried out in a rural property in the municipality of Canindé de São Francisco-SE. The trial was carried out in randomized blocks with 4 repetitions in a 4x2 factorial scheme, with four varieties of palms in two water regimes. The irrigation system used was located with dripped tapes. The agronomic variables studied were: plant height and width, number of paddles per plant, length, width and thickness of the paddle, green mass weight and dry mass weight. To evaluate the production cost in the second cycle of the plant's culture, the effective operating cost (EOC), cost with administrative charge (CEA) and the total operating cost (TOC) were evaluated. The small variety responded positively to the application of irrigation. The varieties: elephant ear, Mexican, girl's hand and giant. There was no increase in the number of rackets with the application of irrigation. The acquisition of mineral fertilizers is the factor that most burdens the total operating cost.

Soybean production in Brazil has reached significant levels, consolidating the country as one of the main global producers. However, adapting soybean cultivars to different regions and climatic conditions is a constant challenge, especially in areas such as the Alto Sertão Alagoano, which has different soil and climate conditions than traditional producing regions. Therefore, the objective was to evaluate the agronomic performance of soybean cultivars in the Alto Sertão Alagoano. The experimental trial was carried out between August 1 and November 30, 2023, in the field, at the Xingó Center for Coexistence with the Semi-Arid, located in the city of Piranhas-AL. The experimental design was in randomized blocks, with five replications. The treatments consisted of four soybean cultivars (BRS 8383 IPRO, BRS 7981 IPRO, BRS 8680 IPRO and BRS 8980 IPRO). The spacing used in the crop was 50 cm between rows and 12.5 seeds per meter, totaling a population of around 250,000 plants per hectare. During the studies, the following agronomic characteristics were analyzed: phenological monitoring, plant height (AP), lodging index (ACA), height of insertion of the first pod (APV), number of pods per plant (NVP), weight of one hundred grains (PCG), grain moisture (U%), productivity in kg ha-1 (PROD.) and in bags ha-1 (SC). The plant evaluations were carried out in the Plant Production and Phytosanitary Laboratories of the Federal Institute of Alagoas, Piranhas Campus. Regarding the variables, AP, APV, ACA, PCG and NVP did not obtain a significant difference at 5% probability by the F test, presenting average values of 56.93 cm; 13.08 cm; 2.09; 12.35 g; 54.76, respectively. Regarding the variables U%, PROD. and SC, they showed a significant difference at 1% probability by the F test, in which the Tukey test was applied (p<0.05). Regarding U%, the cultivars BRS 8383 IPRO (9.8%), BRS 7981 IPRO (10.03%) and BRS 8980 IPRO (10.54%) did not differ from each other, unlike BRS 8680 IPRO (8.97%) which presented a lower moisture content. Productivity in kg ha-1 of the BRS 8980 IPRO cultivar (2,728.56 kg ha-1) stands out, the BRS 8680 IPRO (2,441.75 kg ha-1) and BRS 7981 IPRO (2,279.01 kg ha-1) cultivars presented intermediate values and the BRS 8383 IPRO cultivar (1,587.96 kg ha-1) presented the worst value compared to the others and yield of 45.50 sc ha-1; 40.69 sc ha-1; 37.98 sc ha-1 and 26.46 sc ha-1, respectively.

Several grasses have been evaluated, over the years, for formation of pastures, seeking, above all, high productivity and persistence. Among these, grasses of genus Brachiaria and Panicum are evaluated in other regions such as southeast for example, and in semi-arid region,the type of grass that most arouses curiosity for research is Buffel. For semi-arid regions, another highlight is cactus pear, which feeds and maintains livestock during long periods of drought. Thus, the objective of the present work was to evaluate structural and productive components in intercropping of cactus pear and grass cultivars under irrigated management. The experimental design used was in randomized blocks (DBC), three cultivars of palm in association with one species of grass, in six treatments, palm Nopalea cochenillifera Salm Dyck (miúda-MIU) intercropped with the species of grass and single, palm Opuntia stricta Haw (Orelha de Elefante Mexicana - OEM) intercropped with the species of grass and single, palm Opuntia cochenillifera (Gigante) intercropped with the species of grass and single, six treatments and four replications, totaling 24 experimental units. The rackets were planted densely (1x0.25m) and with buffel between lines. Based on results referring to the study of grass growth and cladode growth in cactus pears, the respective variables were estimated. Biomass production was calculated and, for the evaluation of the morphogenetic characteristics of the cactus pear genotypes, two plants were selected per plot of central line and, as cladodes appeared, they were quantified and marked, weekly, with threads of different colors , according to the order of appearance in cladode hierarchy. Thus, the cladode appearance rate (TApC, cladode/day) and phyllochron (day/cladode) of cladodes were calculated. Weekly, using a ruler and caliper, length, width and thickness of the cladodes were measured, which allowed estimating rates of cladode elongation (TAlC in cm/day), of cladode enlargement (TAC in cm/day), cladode thickening (TEC in cm/day), area expansion (TEA in cm2 /day) and volume expansion (TEV cm3 /day). The biomass production was calculated and bromatological composition was performed. It was verified with this work that consortium of palm OEM, GIG and Miúda with buffel grass can be an alternative for semi-arid region of Alagoas by increasing efficiency in land use.

The cowpea [Vigna unguiculata (L.) Walp] is a nutritionally rich legume, becoming an important food for rural populations. Family Farms in the Northeast region, specifically the Semiarid, cultivate this legume for subsistence, using creole varieties for planting that are adapted to the environmental conditions in which they are inserted. Small farmers often conduct the planting without carrying out the nutritional management of the soil. However, the fertilization of agricultural crops presents high costs for the producer. Therefore, it is necessary to use alternative sources of nutrients. Organic fertilizers are one of the alternatives to the use of these chemical fertilizers, using as an example cattle manure, that is rich in nitrogen and potassium, and that is widely used by small producers. Thus, the objective of this work was to test the productive response of cowpea genotypes under two fertilization managements: organic and conventional. The experiment was conducted at the Federal Institute of Alagoas, Piranhas Campus - IFAL, located in the municipality of Piranhas - Alagoas, from March 2021 to July 2021. The experimental design used was a randomized block design with three replications, in a factorial scheme 4 x 3, where four correspond to the genotypes of cowpea (Corujinha, Manteiguinha, Moita and Canapu, commercial) and three sources of fertilizations (fertilization with cattle manure, mineral fertilization and without fertilization) and three replications, totaling 36 experimental units. When the pods presented characteristics compatible with the harvest point for the production of green beans and dry beans, the harvest was started manually, where the following characteristics were evaluated for the Green Beans: length of green pods (cm) (CVV); number of green pods per plant (NVVP); number of green beans per pod (NGVV); productivity of green beans, where the data were transformed into t ha-1. For dry beans: number of dried pods per plant (NVSP); number of dried beans per pod (NGSV); dry bean yield with subsequent conversion to t ha-1. The collected data were submitted to statistical analysis of variance by the F test, and when significant, the means compared by the Tukey test, at the level of 1% and 5% probability, with the aid of the SISVAR program® version 5.6. Canapu genotype stood out in terms of green and dry bean the production parameters, except in the productivity of dry bean yield, with the Moita variety being the best. The management with mineral fertilization provided the best results and the management without fertilization had better performance when compared to the management with manure fertilization. For green bean yield, the Canapu genotype obtained the best response, with a yield of 1,883.66 kg ha-1 of green beans. For dry bean production, the Moita variety was the best with a yield of 1,203.68 kg ha-1.

The deficit of water in the soil promotes physiological responses in the plant capable of altering the growth, development and yield of the crop, in which it is essential to study the behavior of the plant against water stress to determine the proper management of irrigation. This project aimed to evaluate the effect of water deficit on different phenological stages of corn in the semiarid region. The experiment was conducted at the Federal Institute of Alagoas/Campus Piranhas, from February to June 2019, the experimental design used in the experiment was strips with four replications, in which the treatments were five periods of submission of the crop to deficit stress water, which occurred from the following phases: tanning, pollination, milky grain, pasty grain and farinaceous grain (without stress). From the data collected during the experiment, the following steps were followed:estimation crop evapotranspiration (ETc), analysis of the effect of climatic elements on the crop, evaluation of plant growth, determination of productivity and evaluation of ear variables under the effect of water deficit, and verification of the level of impact of water stress caused in each phenological phase of the crop. Plants subjected to water deficit in the tasseling and flowering phases suffered variation, leaf area index (LAI), number of grains per spike, dry weight of a thousand grains and low yield when compared with plants subjected to the farinaceous grain phase. Radiation, air temperature and humidity do not dissipate in the thermal limitation for corn development throughout the cycle. Plants subjected to water deficit in the tasseling and flowering phase were less productive when compared to plants grown under full irrigation.

Tomato is the second most consumed vegetable in the world and has great socioeconomic importance. However, its productivity is directly affected due to the crop's susceptibility to attacks by various phytopathogenic microorganisms. Bacteria from the Ralstonia solanacearum Species Complex are responsible for the most infectious and devastating bacteriosis of crops in countries with tropical and subtropical climates, bacterial wilt, caused by the obstruction of xylem vessels as a result of the production of exopolysaccharides. The only efficient control measure for this disease is the use of resistant cultivars. Therefore, the objective of this work was to use phytopathometric variables in bacterial wilt in tomato cultivars inoculated with two isolates of Ralstonia pseudosolanacearum. The experiment was conducted from October to November 2023 in a greenhouse at the Instituto Federal de Alagoas – Campus Piranhas. The experimental design used was completely randomized in a factorial scheme (10 x 2), containing 10 tomato cultivars and two isolates of the species Ralstonia pseudosolanacearum, totaling 20 treatments in three replications, resulting in 60 experimental plots, containing four plants each. Using the diagrammatic scale of bacterial wilt scores, phytopathometry of the disease was carried out using the variables: Incidence (INC), Bacterial Wilting Index (BWI), Disease Index (DI), Latency Period (LP50), Area Under Disease Progress Curve (AUDPC) and Infection Rate (IR). These variables were obtained for the interval of the 5th - 10th and 15th - 20th day of evaluation. There was a significant interaction between Cultivars x Isolates, for the following variables: BWI, AUDPC, IR (5th - 10th day of evaluation) and for IMB, ID, and TI (15th - 20th day of evaluation). The variables LP50, INC, IR, and AUDPC characterized the beginning of the bacterial wilt epidemic from the first evaluation interval, regardless of the cultivars and isolates. The cultivar Hawaii 7996 was classified as resistant to isolate CRMRs108, and the cultivar Bartô was classified as moderately resistant to both isolates. The phytopathometric variables were efficient in showing the interaction of host, pathogen, and environment in the evaluation intervals.

This study aimed to evaluate the effect of water stress on the chlorophyll content of corn and to determine the economic irrigation depth for the crop in the Sertão Alagoano region. For this, the hybrid AG7088 was submitted to five irrigation depths (40, 80, 120, 160 and 200% of the ETc) in an experiment carried out at Instituto Federal de Alagoas/Campus Piranhas, with an experimental design in a band scheme and four replications. Three values of price per bag of corn were used to estimate the maximum economic efficiency depth (Xec). Harvest was carried out at 98 DAS, in which grain yield with 12% moisture reached 2,0527 and 11,833 kg ha-1 and water use efficiency of 128.5 and 45 mm t-1 in treatments with 40 and 160% of ETc, respectively. The maximum physical productivity (Ymax) estimated by the production function was 11,267 kg ha-1 , obtained with 919.2 mm of irrigation water. The maximum economic yields (Yec) for the price of a bag of corn equal to R$ 50.00; 80.00 and 110.00 were equal to 10,971, 11,225 and 11,251 kg ha-1 , obtained with water depths of 790.7 (143,6% of ETc), 871 (158,2% of ETc) and 889,5 mm (161,8% of ETc), respectively. The economic blade was 525, 326 and 262 mm, respectively, for the quoted quotation scenarios. The IFC has a direct relationship with the water supply provided, in which the increase in the water supply provides an increase in chlorophyll in the plants up to a certain limit, reducing with the excess of water applied.

In our research, we have undertaken an investigation into the domains of scientific literacy and the teaching of modern physics within the context of secondary education, with a particular emphasis on the theories of relativity. In terms of methodology, this research is essentially qualitative and constitutes a study case. The study sought to scrutinize the prior knowledge of students, propose and implement a pedagogical intervention on the realm of modern physics, specifically focusing on relativity, and evaluate the consequential impact of this intervention on the cognitive framework of the targeted student cohort. This work aims to provide, albeit in a modest and concise manner, the expansive vistas of scientific literacy through the aforementioned area. The research has yielded momentous findings, thereby attaining the stated research objectives. Significantly noteworthy insights have been elucidated, many of which were anticipated in light of the predetermined aims. However, it is notable that certain ideas and perspectives have manifested themselves prominently, diverging from the anticipated preconceptions, yet proving to be highly propitious. Finally, we aim that discussions, such as the one addressed here, can be continuously implemented with the aim of approaching an increasingly prosperous and triumphant educational scenario.

The objective of this Course Completion Work (TCC) is to understand how high school students from a public school, located in the hinterland of Alagoas, perceive the teaching of physics, aiming to reveal what causes the motivations and demotivations of young students regarding the aforementioned curricular component, aiming to contribute, in this way, to the teaching-learning process. Methodologically, the testimonies of young students were collected through non-directive interviews, a technique used to obtain information based on the free speech of the interviewee, through a qualitative approach. In this way, we seek to evaluate, through the students' point of view, what the routine of physics classes is like, seeking key points to support the research problem, in order to support the data collection, directing itself to a suggestion of intervention and positive contribution to the teaching of physics. The general objective, then, is focused on analyzing, from the students' point of view, how physics is taught in high school, how they conceive it and what is the importance of this discipline in their lives. The justification is that, even in the face of so many facts that corroborate the importance of the role of physics for modern society, there are still people who believe that teaching physics is not so important, especially in high school, where it (physics) It is considered an extremely difficult discipline. The research results revealed some of the difficulties faced by students, mainly in the scope of disciplines involving calculations, difficulties that, for the most part, drag on from the 1st to the 3rd year of high school.
