Abstract

The objective of this study was evaluated the effects of calcium (Ca) and boron (B), applied to leaf spraying at different stages of soybean, on yield components and productivity of soybean (Glycine Max).The experimental design was randomized blocks with four blocks. The treatments consisted of spraying the commercial solution with calcium and boron (10.0% Ca, 0.5% B), at dose of 3.0 L ha-1 in four different phases: 10 days before flowering (flower buds closed) R1 stage, in full bloom (with more than 80% anthesis) R2 stage, 15 days after full bloom (pods with 3 to 5mm) R3 stage and 30 days after full bloom (pods with 15mm) R4 stage, and a control without application of foliar fertilizer. The yield components evaluated were legumen number/plant, grain number/legumem, grain weight and productivity. Application of Ca and B did not influence soybean yield in any application stage. The yield components; legumen number/plant, grain number/legumem, grain weight did not differ significantly with application to leaf spraying of Ca and B, probably due to their adequate content in soil and water availability during the growing season.
