| O presente trabalho teve como avaliar o efeito de diferentes temperaturas na redução do período de embebição de sementes de soja no teste de condutividade elétrica. Utilizaram-se sementes colhidas no estádio R8 e aos 15, 30 e 45 dias após R8, as quais foram armazenadas em câmara fria até a realização dos testes de avaliação da qualidade fisiológica. No teste de condutividade elétrica, foi estudada a metodologia tradicional, com quatro repetições de 50 sementes embebidas em água na temperatura de 25oC por 24 horas e duas outras metodologias, constituídas de 20 repetições de 10 sementes com tempo de embebição de 10, 30, 60 e 120 minutos nas temperaturas de 32oC ou de 40oC. Pelos resultados obtidos observou-se que a elevação da temperatura diminuiu o tempo de... |

| ABSTRACT: The appearance of soybean cultivars that are tolerant to herbicides from the imidazolinone group enables irrigated rice rotation conducted on Clearfield® system. The objective of this work was to evaluate the morphological and metabolic changes of soybean cultivars containing Cultivance® (CV), which is tolerant to imidazolinone, sulphonylurea toletant (STS) and Roundup Ready® (RR), which is tolerant to glyphosate as affected by carryover of increasing doses of imazapyr and imazapic herbicides mixture, applied in the management of irrigated rice crop. Thus, experiments were conducted on the field and in greenhouse, evaluating phytotoxicity, height, leaf area, shoot dry matter, as well as variables related to the secondary metabolism of plants like... |

| The research aimed to evaluate machine traffic effect on soil compaction and the least limiting water range related to soybean cultivar yields, during two years, in a Haplustox soil. The six treatments were related to tractor (11 Mg weight) passes by the same place: T0, no compaction; and T1*, 1; T1, 1; T2, 2; T4, 4 and T6, 6. In the treatment T1*, the compaction occurred when soil was dried, in 2003/2004, and with a 4 Mg tractor in 2004/2005. Soybean yield was evaluated in relation to soil compaction during two agricultural years in completely randomized design (compaction levels); however, in the second year, there was a factorial scheme (compaction levels, with and without irrigation), with four replicates represented by 9 m² plots. In the first year,... |
