Agregados do solo e índices de agregação em áreas de vegetação nativa, agricultura e pastagem no semiárido de Alagoas
(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
(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.
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.

(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, 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.

(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2023-12-20) Farias, Thassila Silva De; Silva, Jose Madson da; http://lattes.cnpq.br/5749870599305506; Souza, Ênio Gomes Flôr; Oliveira Filho, Antônio Francelino de; http://lattes.cnpq.br/7940724279029705
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.

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.

This research to conclude the Environmental Management course has as its methodology the study of an exploratory and investigative nature, where data were collected through a semi-structured questionnaire with the aim of analyzing the profile of farmers registered in the Merenda da Terra da Program. city of Marechal Deodoro in the state of Alagoas. A bibliographic review study was also used to better understand and analyze what was collected. The description of the context where farmers produce and sell enabled recommendations for the difficulties and limitations identified in the program. Therefore, there were 35 farmers interviewed from 37 active farmers, out of a total of 67 registered. Challenges to be addressed in the program were identified as an incentive to improve and increase production, requiring investments for this to occur; the lack of interest among young people in these families in current production and the continuity of agriculture in the family; the need for these families to organize themselves into associations or cooperatives, possibly gaining greater unity and robustness, thus assisting in the production/cultivation, sale and distribution processes; and implementation of the SAF’s Agroforestry System as a possible efficiency for recovering soil nutrients for the benefit of agricultural cultivation.

Tomato is one of the most important vegetable crops in the world, representing a significant source of employment and income, mainly in Brazilian Northeast, where risks of soil salinity constitute limiting factors for good crop development. Breeding programs for selection of progenies that tolerate this abiotic stress are essential. Then, the objective of this work is to select salinity-tolerant tomato progenies. For the experiment, 400 plants of F3 generation, 400 plants of F2 generation, 60 F1 plants and 60 plants of each parent, that is, the IPA-7 and Yoshimatsu cultivars, totaling 980 plants; for the second experiment, 400 plants of F2 generation, 60 plants of F1 and 60 plants of each parent (Yoshimatsu and IPA-7), totaling 580 plants, at a high level of salinity, in four replications were evaluated. The experiment was carried out in pots for 30 days, with evaluations taking place during 20 and 30 days after transplanting. On evaluation for the first experiment, morethan 50% of generations at 20 days demonstrated that they are tolerant, already at 30 days only the Yoshimatsu genitor showed tolerance, where others were not tolerantg, with variations in notes. For evaluation of the second experiment at 30 days after transplanting, as in the first one, only Yoshimatsu genitor was tolerant and others demonstrated more than 70% of generations not tolerant to saline level. The selection of tomato progenies is indicated from 30 days after transplanting. Through the F2 and F3 generations, dominance of non-tolerant phenotype was observed, indicating that possible salinity tolerance genes are recessive. Through the inheritance study that indicated the action of another recessive gene combined with experimental conditions, it was not possible to select salinity-tolerant progenies.

Irrigation in agriculture allows conditions for genetic material to express its full production potential in the field, but scientific studies are needed to optimize the use of water in regions of difficult access to it, such as semi-arid regions. Therefore, the present study aimed to determine the economic irrigation depth for cowpea cultivation in the Sertão Alagoano region.A creole variety commonly cultivated by farmers in the region was used, which was subjected to five irrigation depths (30, 60, 90, 120 and 150% of crop evapotranspiration-ETc). The experiment was developed at the Federal Institute of Alagoas/Campus Piranhas, during the months of February to May 2018. The culture was irrigated by drip, in which irrigation costs plus planting costs and cultural treatments were used to determine the economic level of water, through the analysis of grain productivity. Yield differed statistically between the slides applied, according to the F test (p<0.05). The culture of cowpea of creole genetic nature has a low response to irrigation, in which the economic depth is independent of the selling price of the grain and is close to the depth that provides maximum physical yield.

The Caatinga biome predominates in much of the northeast region of Brazil, comprising about 48% of the state of Alagoas, extending across several municipalities, including the municipality of São José da Tapera. The Caatinga has been suffering suppression processes that have put the diversity of forest and animal species in this biome at risk. Therefore, it is necessary to create alternatives to minimize the effects of human and natural actions. The native plant nursery can be assumed as an alternative to minimize such effects, in addition to serving as a laboratory for studies in the area. From this idea, the present work aimed to build a nursery of native plants in a participatory way, involving the residents of the Caboclo village community, located in the municipality of São José da Tapera, located in the backlands of the State of Alagoas. The methodology used in this study used a qualitative and quantitative approach, associated with an action research, as it is a participatory investigation. The study was subdivided into 6 stages, namely the presentation of the project, the beginning of conversation circles on fauna and flora themes, visiting existing nurseries, obtaining seeds, setting up the nursery and planting seedlings. The study sample included 54 students who attend the only public school in the village and were selected with the support of the school coordination. At the end of the stages, it became evident that the nurseries can be used as environmental education strategies, as they help to preserve the entire web and life cycles of a biome.
