Item Biometria e produtividade de grãos de híbridos de milho no alto sertão sergipano(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/5749870599305506Corn 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).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.Item 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 Silagem a base de capim-elefante, feijão guandu e milho(INSTITUTO FEDERAL DE ALAGOAS - Ifal, 2023-12-19) Silva, Mayara da; Costa, Kleyton Danilo da Silva Costa; https://orcid.org/0000-0003-4631-3240; http://lattes.cnpq.br/3562128215536520; Silva, Randerson Cavalcante; http://lattes.cnpq.br/7477067848979919; Silva, Jose Madson da; https://orcid.org/0000-0003-0237-4762; http://lattes.cnpq.br/5749870599305506; Silva, Michelangelo de Oliveira; http://lattes.cnpq.br/5831953262176334The use of forage conservation techniques plays a fundamental role in animal feeding and nutrition, ensuring the supply of quality food during periods of drought. Ensiling is one of the most used techniques for forage conservation, which consists of the anaerobic fermentation of forage, resulting in the production of lactic acid, inhibiting unwanted microorganisms and preserving the quality of the silage. The appropriate selection of the plant to be ensiled plays an extremely important role, as its composition directly influences the quality of the silage. Silage production using elephant grass, gaundu beans and ground corn emerge as efficient nutritional alternatives due to their nutritional composition, favorable cost-benefit, resistance to adverse weather conditions and potential increase in animal productivity. Therefore, the present work aimed to analyze the chemical composition and fermentative parameters of silage produced with different levels of protein using elephant grass cv. BRS Capiaçu, pigeon pea cv. IPA 43 and ground corn, seeking to highlight which treatment has the best bromatological and fermentative quality. The experiment was set up in a Completely Randomized Design (DIC), with four treatments and five replications, totaling 20 experimental plots. Each treatment presented a different protein level, these being 11, 12, 13 and 14% of crude protein (CP). The fermentation profile was evaluated by measuring °Brix, pH, temperature, dry matter losses through gases (PG) and green matter losses through effluents (PE), in bromatological analysis the CP and Dry Matter contents were determined ( MS). The treatment with 14% CP demonstrated better performance in terms of DM, with 31.8% DM, and PG with 5.38% losses. CP analysis did not indicate losses during the fermentation process. Although the temperature showed a significant difference, all treatments remained within the acceptable temperature range according to the literature, with an average of 25.76°C. The parameters pH, °Brix and PE did not show significant differences between treatments, with averages of 4.41, 6.99 and 1.78 Kg/Mg respectively, remaining at levels suitable for making quality silage. The silage formulation presented adequate bromatological and fermentative parameters at all protein levels. The treatment with 14% protein is the most recommended as it presents a greater amount of dry matter and lower gas losses.
