(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2022-06-06) Silva, Ayanna Araujo; Maia, Stoecio Malta Ferreira; http://lattes.cnpq.br/6110419050119583; Calheiros, Altanys Silva; http://lattes.cnpq.br/9353777923030637; Medeiros, Aldair de Souza; http://lattes.cnpq.br/7861355880079380
The expansion of agricultural activities with conventional management in the semi-arid region of Brazil, associated with the intrinsic characteristics of the soil in this region, can directly or indirectly influence soil aggregation and, consequently, the storage of soil organic carbon (COS). Thus, the objective of this work was to evaluate the impacts promoted by conventional land use systems (agriculture and pasture) on the stability of aggregates of different types of soils in the municipalities of Traipu and Santana do Ipanema, located in the semi-arid region of the state. From Alagoas. Soil samples were collected in the municipalities of Traipu and Santana do Ipanema. In total, four areas were sampled. In each of the areas, samples were collected in three trenches (replications) at different depths. The stability analysis of aggregates in water was performed using Yoder's agitator equipment, and later, the soil aggregation indices were calculated: weighted average diameter, geometric average diameter, stability index and instability index. The results obtained were submitted to analysis of variance (ANOVA) using the F test. Differences between the means were tested using the Tukey test (p<0.05). The results showed that the pasture system with less time (4 years) presented smaller amounts of macroaggregates (diameter >2.00 mm), and greater distribution of mesoaggregates (diameter of 2.00 and 0.25 mm) and microaggregates (diameter < 0.25 mm) compared to native forest and other pastures. The IS values revealed that the agricultural system with 47 presents physical conditions of the soil closer to its natural form in the deeper layers of the soil.

Nettle is a plant found in various regions of the world, including Brazil, where it can be found in abundance in the backlands of Alagoas. Some pharmaceutical industries use its extract in the production of drugs, thanks to its rich variety of substances. The objective of this study was to use nettle extract as a potential nutritive agent, capable of stimulating the growth of corn crops. The methodology used was, initially, planting plots of corn, which were sprayed for 75 days; then the aerial part was evaluated by measuring diameter and height, using a caliper. It was found that in the evaluation of plant diameter, in the period of 15 days, the best doses were between 200 and 800 g, and on the other days, the best dose was 200 g. For the height variable, in the 15-day period the best dose was 600 g, but it did not differ statistically from the results presented at 30 days, where the best doses presented were 200 to 600 g. In relation to 45, 60 and 75 days the best dose was 200 g of nettle. Thus, it is concluded that using nettle extract from the 200 g dose onwards caused a reduction, decrease in the diameter and aerial part of the plant.
Ánalise meteorológica, produtividade e crescimento do milho irrigado durante as estações de verão e inverno no sertão alagoano

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.
Avaliação do consumo de leite e derivados lácteos por alunos do curso subsequente do Campus Satuba
(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2025-08-29) Santos, Tereza Leticia da Silva; Lyra, Daniele Gomes de; http://lattes.cnpq.br/5731038200690699; Lima, Marciara Lúcia dos Santos; http://lattes.cnpq.br/7363169253014822; Silva, Tâmara Lúcia dos Santos; http://lattes.cnpq.br/7697002445483904
Milk and dairy products are important sources of nutrients in the human diet, providing high biological value proteins, calcium, and essential vitamins. This study aims to investigate the milk and dairy product consumption habits among students enrolled in the post-secondary technical course at the IFAL– Satuba Campus. Data collection was carried out through a structured questionnaire that addressed aspects such as student profile (age, gender, income, and place of residence), preferences and frequency of milk and dairy consumption, and factors influencing this consumption. The questionnaire was created using the Google Forms platform, resulting in 50 responses, which represent 61.7% of the enrolled students. The results revealed the following profile of the respondents: 54% identified as female, 64% reported a household income of up to one minimum wage, and 60% reside in rural areas of the state. Regarding the type of milk most consumed, powdered milk was preferred by 72% of respondents. In terms of fat content, whole milk accounted for 84% of preferences. UHT milk showed low consumption within this group (22%). As for raw milk, 22% of the respondents reported consuming it at least once a week. The predominant form of milk consumption was with coffee (50%). Among dairy products, butter was the most consumed, and mozzarella was the most preferred cheese, with 54% of the responses. Only 4% reported not consuming milk at all. The most considered factors during purchase were brand and price, while the expiration date was the main criterion when choosing the product. Thus, the data indicate that among students in the post-secondary Agriculture course at IFAL – Satuba Campus, the predominant choice is whole powdered milk, which aligns with the researchers' expectations. However, the study also revealed a still frequent consumption of raw milk, which raises concerns regarding food safety. It is known that the consumption of unpasteurized milk remains common in rural areas of the country, which may explain this finding. Therefore, it is essential to develop awareness- raising actions aimed at the academic community to highlight the health risks associated with the consumption of raw milk.
Avaliação sensorial de doce de leite pastoso de diferentes marcas do mercado de Maceió-AL

Dulce de leche is a traditional product obtained by concentrating milk with sugar under heat, and may contain other ingredients permitted by legislation. In terms of production and consumption, Argentina, Uruguay, and Brazil stand out. Much of its production occurs on a small, artisanal, and discontinuous scale, which contributes to the lack of uniformity and standardization in the product’s physicochemical and sensory characteristics. The objective of this study was to evaluate the sensory attributes (color, aroma, flavor, texture, and overall acceptance) and purchase intent of dulce de leche products available in retail markets in the capital city of Alagoas. The samples were purchased in major supermarket chains without prior selection criteria. After acquisition, the products were sent to the Sensory Analysis Laboratory of the Federal Institute of Alagoas – Satuba Campus, where they were stored under refrigeration until the analyses were performed. Subsequently, the samples were coded and randomized (A, B, C, D, E, and F). A total of 65 untrained panelists participated in the test using individual trays containing water, samples, and an evaluation form composed of two scales: a nine-point hedonic scale (9 – liked extremely / 1 – disliked extremely) and a three-point purchase intent scale (3 – would certainly buy / 1 – would certainly not buy). The experimental design adopted was a complete block design, varying according to samples, panelists, and error. The Acceptability Index (AI) was calculated using the formula AI (%) = (A × 100) / B, and Tukey’s test was applied (p < 0.05). Data analysis showed that the predominant age group among participants was 15–25 years (83%), with the majority being female (54%). All samples achieved an AI above 70%, the minimum value considered acceptable. Notably, sample F obtained an AI above 90% for all attributes except aroma (85%). Sample B recorded the second- highest AI, reaching 90% in overall acceptance and in the attributes of flavor and texture, but lower percentages for color (84%) and aroma (87%). This reduction may be associated with a higher presence of bicarbonate, according to panelists’ comments such as “overcooked,” “tastes like chocolate,” and “burnt tone.” Sample C, which achieved the third-highest indices, obtained 89% in overall acceptance and flavor, and above 86% for the remaining attributes. This result is noteworthy considering that sample C is of Argentinian origin and contains vanilla essence and glucose in its formulation, whereas samples F and B are Brazilian in origin, more readily available in local markets, and do not contain these ingredients (vanilla/glucose). No significant differences were observed for the attributes color and aroma among samples. However, only samples D and F differed in overall acceptance. Regarding purchase intent, samples B, C, and F obtained the highest percentages in the “would certainly buy” category (68%, 58%, and 68%, respectively). It is concluded that the evaluated brands demonstrated high sensory acceptance, and the study contributes to addressing the scarcity of research related to the lack of physicochemical/sensory uniformity and the consumer profile of dulce de leche.

(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).

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.

Milk is the best natural food because it contains relatively important essential nutrients to the diet. However the treatment to which the milk is subjected in the industry can modify their nutritional characteristics. The milk powder is a modern form of milk consumption. The nutritional value of milk powder and other lactic derivatives is substantially lower than that of milk, but should take into account that these products have longer shelf life, enabling economic gains in storage and transport. The milk powder generally has a large role in the food category. Unlike powdered milk, milk compound, can not be called milk because it has other ingredients in its composition, milk food substances or not milk is made from milk, milk reconstituted where the base has to be at least 51% of the total product.
Controle genético da tolerância à salinidade em tomateiro

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.

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. The BRS 8980 IPRO cultivar stood out, being superior in the variables of grain moisture and productivity, showing excellent adaptation and stability in the Alto Sertão Alagoano.

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.

(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2025-08-27) Silva, Nayra Vanessa da; Mendonça, Ariadne Aguiar Vitório; https://lattes.cnpq.br/2209991418027624; Barros, Ágda Christiane Farias de; https://lattes.cnpq.br/0590565949758637; Mendonça, Ariadne Aguiar Vitório; https://lattes.cnpq.br/2209991418027624; Melo, Wagner Wildey Silva de; https://lattes.cnpq.br/2359431281059741
Artisanal gelato, distinguished from ice cream by its creamier texture and reduced air incorporation, has gained prominence due to the possibility of innovative formulations with functional ingredients. Among these, green banana biomass (Musa spp.) presents a relevant technological and nutritional alternative, acting as a natural thickener and source of resistant starch. In this context, this Final Project aimed to develop artisanal gelato formulations with the addition of green banana biomass and coconut, evaluating their sensory acceptance and studying the physical structure of a small-scale artisanal production. The research was characterized as experimental, applied, documentary, and bibliographic. Three formulations were prepared with different biomass concentrations (10%, 20%, and 30%) and subjected to sensory testing with 85 untrained panelists, using a 9-point hedonic scale and a purchase intention test. The results showed that the formulation with 10% biomass (F1) achieved the best acceptance rates for flavor and texture, as well as the highest purchase intention. Production was carried out using an artisanal producer, which favored adequate homogenization and reduced air incorporation, resulting in products with positive sensory characteristics. An analysis of the physical structure of three artisanal ice cream shops in Maceió, Alagoas, was also conducted, based on ANVISA's RDC No. 275/2002, highlighting the importance of layout, good manufacturing practices, and sanitary organization, even in small-scale production. The conclusion is that green banana biomass is a viable alternative for the production of gelatos with functional and sensory appeal, strengthening the development of healthy, sustainable, and regional products, in addition to promoting artisanal production in the dairy sector.

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.

Dulce de leche is a widely consumed product in Latin America, obtained by concentrating milk with the addition of sucrose and other ingredients under constant heat. Acerola (Malpighia emarginata) is a small, round to obovate fruit with an intense red color when ripe, featuring juicy pulp, a unique flavor, and high nutritional value, especially in vitamin C content (7004,000 mg/100 g). This fruit can be consumed fresh, as frozen pulp, juice, or jelly. Jelly is defined as a product obtained by concentrating fruit pulp or juice with added sucrose. The incorporation of tropical fruits, particularly acerola, into dulce de leche adds value to the product and offers consumers differentiated alternatives. This study aimed to evaluate the sensory acceptability and purchase intention of dulce de leche with acerola jelly. The raw milk was obtained from the Dairy Cattle Laboratory of the Federal Institute of Alagoas – Satuba Campus, and other ingredients were purchased locally. In the agro-industry laboratory, dulce de leche and jelly were prepared; in the sensory analysis laboratory, three formulations were developed with varying jelly content: F1 (25%), F2 (50%), and F3 (75%). For the sensory test, 60 untrained consumers were recruited and, in individual booths, received a tray with the three formulations labeled with random three-digit codes, water, and an evaluation sheet containing two scales: a nine-point hedonic scale (9 – like extremely, 1 – dislike extremely) for overall impression, color, aroma, texture, and flavor; and a three-point purchase intention scale (3 – would certainly buy, 1 – would certainly not buy). The experimental design was a complete block design, with analysis of variance (ANOVA) followed by Tukey’s test (p < 0.05) and the Acceptability Index (AI% = A × 100 / B). Data showed a predominance of female participants (90%), with most aged between 15 and 25 years. All attributes scored above 70%, meeting the minimum recommended threshold for new product acceptability. Overall impression scores ranged from 87% to 89%, color from 90% to 92%, texture from 89% to 90%, and flavor from 85% to 90%. Aroma scored 83%. Regarding purchase intention (“would certainly buy”), results were F1: 63%, F3: 58%, and F2: 50%, with the remainder selecting “might buy.” The lower jelly percentage in F1 likely contributed to its higher scores across attributes. No significant differences were observed among formulations. It is concluded that all formulations demonstrated excellent acceptability among young consumers, indicating that incorporating acerola jelly into dulce de leche is feasible both sensorially and commercially, especially given acerola’s easy availability and high nutritional value.
