Abstract

Previous studies with another legume, black gram (Vigna mungo L. Hepper) showed that seed with <6 mgB/kg dry matter (DM) had depressed germination % in the laboratory (1), and seed with <10 mgB/kg produced abnormal seedlings when planted in the field (2l. In the present study at Chiangmai, Thailand on a low B soil (Typic Tropaqualf), we examined the effect of B levels in soybean seed and B levels in the soil on seedling establishment, crop growth and final seed yield.
