Item 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 Qualidade fisiológica de sementes crioulas de feijão-comum provenientes do sertão alagoano(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2024-08-08) Bezerra, Mítila Mayane Silva; Marques, Fabio Jose; https://orcid.org/0000-0002-7043-4125; http://lattes.cnpq.br/2597421090332829; Costa, Kleyton Danilo da Silva; http://lattes.cnpq.br/3562128215536520; Silva, José Madson da; https://orcid.org/0000-0003-0237-4762; http://lattes.cnpq.br/5749870599305506The common bean (Phaseolus vulgaris L.) is an important source of food and income for Brazilian farmers, mainly used for grain production. It is a traditional legume for country families, where it demands lower technological levels to be cultivated, which can, potentially, decrease its productivity and unevenness in the field. Given that, creole seeds play an important role due to their genetic variability, adaptation, and low cost. To guarantee satisfactory performance in the field, as well as their perpetuation, it is crucial that, beyond having desirable genetic characteristics, the seeds present a good physiological potential. Thus, knowing the physiological quality of established creole materials is essential to their conservation, proper use, and good performance. Accordingly, this work aims to assess the physiological quality of creole genotypes of common bean from Alagoas’ semi-arid region. The experiment was conducted in the plant production laboratory at IFAL Piranhas campus, using seven genotypes of P. vulgaris, including six heirlooms from the Poço Doce II community, Piranhas-AL municipality (Carioquinha, Mulatinho, Mulatão, Preto, Leite, and Vagem Roxa) and one commercial variety (BRS-FC-402) as a control, comprising seven treatments. A Completely Randomized Design (CRD) was used, with 7 treatments (seven genotypes) and 4 replications, totaling 28 sample plots. To analyze seed quality, the following tests were performed: Germination Test, evaluating the parameters of Germination, First Germination Count, Seedling Dry Mass, and Seedling Shoot Length; the Tetrazolium Test, evaluating vigor and viability; and the Electrical Conductivity Test. The germination test was based on the Rules for Seed Testing (RAS), and the others were adapted from the book "Seed Vigor: Concepts and Tests." The obtained data were subjected to analysis of variance, and when significant effects were observed by the F-test (p<0.05), the Scott-Knott grouping test was applied at 5% probability. No significant differences were observed among the genotypes in the germination test, first germination count, and vigor by the tetrazolium test. For seedling shoot length, the Preto genotype had the highest value, followed by the Carioquinha and Mulatão genotypes, with the others in the lower-length group. The Vagem-Roxa, Mulatão, and Leite genotypes stood out in terms of seedling dry mass. Regarding viability by the tetrazolium test, only the Mulatão genotype showed significantly lower values. In the electrical conductivity test, the Mulatinho, Carioquinha, Mulatão, and Vagem-Roxa genotypes stood out. The results demonstrate that the seeds of the heirloom bean varieties from the Alagoas backlands exhibited high and comparable physiological quality when compared to the commercial cultivar.
