- Abstract
The seeds of vegetable soybeans (Glycine max (L.) Merrill), the same species as the common soybean, have some special characteristics, such as: flavor, texture differentiated for use as vegetable, being consumed when the seeds are still immature at the R6 stage. The objective of this study was to evaluate the effect of five types of fertilization and evaluation times in the health and viability of seeds of vegetable soybeans cultivar BRS 258, and lineage BR 9452273. The experimental design was a randomized block, 5 x 2 factorial design with four replications. The factors consisted of five types of fertilizer and two evaluation periods (after harvest and the twelve months of storage). For treatments with twelve months of storage, the seeds of vegetable soybeans of both genotypes were stored in polyethylene bottles terephthalate (Pet). Seeds were subjected to stringent health and germination tests. The average reduction in seed quality during storage was 4% for BRS 258 and 23% for BR 9452273. The reduction in seed quality of the two genotypes was not affected by the fertilization method used, nor by pathogens and bacteria saprophytes, but by the storage in polyethylene terephthalate bottles for 12 months.
