Abstract

Soybean (Glycine max (L.) Merrill) is a crop of great economic and social importance in Brazil, being necessary to advocate the use of high quality seeds to ensure the adequate provision of plants in the field, avoiding the replanting and guaranteeing an income satisfactory. In this context, the study aimed to evaluate and compare the strength and viability of commercial seed of soybean seeds produced in the off-season home in two cities of the western region of Paraná. The experiment was conducted at the Seed Technology and Physiology, State University of Paraná, Marechal Cândido Rondon (PR). The experimental design was completely randomizes design with four replications and three treatments, wich refers to lots of seeds with different origins of production: commercial crop grown in summer (COM), home-produced Cafelândia (CAF) and home-produced Marechal Cândido Rondon (MCR). The physiological seed quality were evaluated through the tests: first germination count, electrical conductivity, tetrazolium and accelerated aging; and viability was assessed by germination and tetrazolium. It is concluded that seeds produced in the second crop, as well as commercial seed can be used for planting in the conventional period, provided that it is a proper management culture ensures the physiological quality of seeds.
