DANO MECÂNICO DE COLHEITA E QUALIDADE FISIOLOGICA DE SEMENTES DE CULTIVARES DE SOJA NO ARMAZENAMENTO

Abstract

Soy is one of the most cultivated cereals in the world, being of paramount importance in the agricultural scenario as well as being linked to the country's economic growth. The traceability of lots of soybean seeds, following all stages of production, storage and their destination such as sale to the end customer, guarantees the quality of the lots of seeds that will be passed on, bringing credibility to the supplier and guaranteeing quality seeds for the consumer. The objective of this work was to verify the traceability and storage of three soybean cultivars, in soybean seed production fields, and their impacts on the quality of these seeds. The experiment was conducted in two phases: in the field in the 2022/2023 harvest in the period from January to March, and in the laboratory from April to October, the cultivars that were monitored are DM 73i75, Olimpo IPRO, Bônus, checking mechanical damage, through sodium hypochlorite solution and water, and part of laboratory are testing monthly moisture received x moisture accepted, mechanical damage received x mechanical damage accepted, vigor received x vigor accepted, moisture damage, mechanical damage test with 3 repetition, test stink bug damage with 3 repetitions, specific leaf mass, vigor levels in 3 repetitions, and the TZ (tretazolium) test, a 0.075% concentration solution will be used, thus allowing the development of adequate seed color and identification of damage mechanical, since all tests have the same property, the statistical analysis was carried out using the 5% tukey test, observing significant variations. 4 Each variety behaved differently in the tests carried out, and also differed over the storage period, but overall, the Bonus cultivar presented better results when compared to the others.
