QUALIDADE DE SEMENTES DE SOJA CERTIFICADAS E SALVAS PRODUZIDAS NA BAHIA, REGIÃO MATOPIBA

Abstract

Soybean seeds produced and saved by producers may present differences in quality when compared to certified seeds, and may also present greater losses when stored. During this time, seed degradation cannot be completely avoided, but its speed and severity can be reduced, depending on the conditions of the storage environment, especially in relation to temperature and relative humidity. Therefore, the objective of this study was to evaluate the quality of certified, stored and saved soybean seeds produced in the Matopiba region. The variety used was Intacta Monsoy 8349 soybean, obtained in the 2022/2023 and 2023/2024 harvests at Fazenda Santa Terezinha, located in the municipality of Correntina - Bahia, being a certified batch stored for 6 months, a saved batch from the 2023/2024 harvest and a certified batch stored. This study was carried out in the laboratory of the Instituto Federal de Educação, Ciência e Tecnologia Goiano - Campus Posse. In order to assess the potential and quality of the seed lots, germination, sodium hypochlorite, electrical conductivity, thousand-seed weight, moisture, tetrazolium test and emergence test in seedbed were performed. The experiment was carried out in a completely randomized design with five replicates. The data obtained were analyzed by analysis of variance and Tukey's test, using the SISVAR software. It was found that the saved, certified and stored certified seeds presented differences in their physiological and physical quality. Key-words: seed storage; seeds production; fisic and phisiology qualityy.
