Resumo: Changes in the soybean sowing season directly reflect on the physiological potential of the seeds produced. This study aimed to identify sowing seasons that qualitatively improve the soybean seeds yield. The experiments were conducted in two growing seasons, in a 2 × 4 × 6 factorial scheme, with four sowing seasons and six soybean cultivars (Don Mario 5.8i RR, BMX Energia RR, BMX Força RR, BRS 255 RR, BRS 294 RR and BRS 295 RR). A complete randomized blocks design, with three replications, was used. Twelve informative quality characteristics of soybean seeds were evaluated, based on tests of germination, mechanical damage, accelerated aging and tetrazolium. The sowing season and cultivars significantly affected seed quality. A difference in the sensitivity of cultivars to variations in the sowing season was noticed, concerning seed quality attributes. Sowings in mid-December are recommended for high quality seed production.

Este estudo objetivou identificar épocas de semeadura que maximizem qualitativamente a produção de sementes de soja. Os experimentos foram desenvolvidos em dois anos agrícolas, em esquema fatorial 2 × 4 × 6, com quatro épocas de semeadura e seis cultivares de soja (Don Mario 5.8i RR, BMX Energia RR, BMX Força RR, BRS 255 RR, BRS 294 RR e BRS 295 RR). Utilizou-se o delineamento de blocos casualizados, com três repetições. Foram avaliadas doze características informativas da qualidade de sementes de soja, por meio dos testes de germinação, dano mecânico, envelhecimento acelerado e tetrazólio. Houve efeito significativo da época de semeadura e de cultivares sobre a qualidade das sementes. Constatou-se diferença na sensibilidade das cultivares a variações na época de semeadura, quanto aos atributos qualitativos de semente. Semeaduras em meados de dezembro são recomendadas para a produção de sementes com qualidade superior.Escola de Agronomia - Universidade Federal de Goiás2015-03-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistas.ufg.br/pat/article/view/29143Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 45, n. 1, Jan./Mar. 2015; 46-55Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 45, n. 1, jan./mar. 2015; 46-55Pesquisa Agropecuária Tropical; v. 45, n. 1, jan./mar. 2015; 46-551983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/29143/18075Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessBornhofen, ElesandroBenin, GiovaniGalvan, DanielleFlores, Mariana Faber2020-07-13T16:01:50Zoai:ojs.revistas.ufg.br:article/29143Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2020-07-13T16:01:50Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)false
