Item 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/5749870599305506The 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.Item Anuário de Sustentabilidade das Unidades Agroindustriais Sucroenergéticas de Alagoas(2022-09-30) Cardoso, Michelle da Silva; Prates, Fabiano Barbosa de SouzaNenhumItem Desempenho produtivo de genótipos de feijão [Vigna unguiculata (L.) Walp] em função de fontes de adubos(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2021-10-08) Veloso, Cássio Laurentino; Marques, Fábio José; https://orcid.org/0000-0002-7043-4125 ; http://lattes.cnpq.br/2597421090332829; Marques, Fábio José; https://orcid.org/0000-0002-7043-4125; http://lattes.cnpq.br/2597421090332829; Prates, Fabiano Barbosa de Souza; http://lattes.cnpq.br/6530012770891274; Silva, José Madson da; https://orcid.org/0000-0003-0237-4762; http://lattes.cnpq.br/5749870599305506The 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.Item Manual para Avaliação de Sustentabilidade das Unidades Agroindustriais Sucroenergéticas de Alagoas(2022-09-30) Cardoso, Michelle da Silva; Prates, Fabiano Barbosa de SouzaNenhumItem Seleção de progênies de tomateiro (Solanum lycopersicum l.) tolerantes à salinidade(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2023-01-27) Nascimento, Thamara Pereira do; Costa, Kleyton Danilo da Silva; https://orcid.org/0000-0003-4631-3240; http://lattes.cnpq.br/3562128215536520; Silva, Michelangelo de Oliveira; http://lattes.cnpq.br/5831953262176334; Prates, Fabiano Barbosa de Souza; http://lattes.cnpq.br/6530012770891274Tomato 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.Item Viabilidade técnica da manta geossintética na produção de pimentão em função de diferentes lâminas de irrigação em Arapiraca, Alagoas.(Instituto Federal de Educação Ciência e Tecnologia de Alagoas, 2020-06-26) Oliveira, Sílvio Serafim; Cavalcante, Marcelo; http://lattes.cnpq.br/0221717690546039; Calheiros, Altanys Silva; http://lattes.cnpq.br/9353777923030637; Prates, Fabiano Barbosa de Souza; http://lattes.cnpq.br/6530012770891274; Santos, Márcio Aurélio Lins dos; http://lattes.cnpq.br/0192590447392368Pepper is among the ten most important vegetables in terms of economic value in Brazil, with Alagoas ranking 7th in the Northeast. The Arapiraca city is responsible for the production of 43.6% of the pepper produced in the State. However, due to the city being inserted in the semiarid region, the use of efficient techniques of use and management of water and soil is of great importance for agricultural activity. For these reasons, aimed, with this research, to evaluate the technical viability of the Soiltain® DW woven geosynthetic under three irrigation levels, in the cultivation of peppers in Arapiraca, Alagoas. The experiment was conducted in split-plot design, being in the main plots three irrigation levels (60, 100 and 150% of ETc) and in the subplots, four soil coverings (SoilTain® DW woven geosynthetic, bare soil, synthetic white and organic Mulchings), with five replications, totaling 12 treatments, with five replications. Agromorphological variables, components of pepper production, and soil temperature were evaluated. There was a significant interaction between the treatments, in which the woven geosynthetic showed superior results to white Mulching in relation to plant heights, stem diameter, leaf width and water use efficiency in the three irrigation depths, together with the bare soil treatments and organic Mulching. The 150% ETc level favored higher plant mortality during the crop development period, with a reduction in the stand, reducing yield, which ranged from 40.33 t ha-1 for white Mulching to 57.18 t ha-1 for organic Mulching. The soil temperature negatively influenced the development of the crop, being higher in white Mulching in all evaluations. The blanket also promoted greater profit and lower production cost and, likewise, the 100% ETc. level. The SoilTain® DW woven geosynthetic is viable as an alternative Mulching, and it is recommended to associate it with the 100% ETc level.
