FOLIAR APPLICATION OF CALCIUM AND BORON WITH INDUSTRIALIZED PRODUCTS FOR EVALUATION OF QUALITY AND INCOME OF SOYBEAN SEEDS.

Abstract

This experiment was in the field with the soybean cultivar BRS Valuable RR, applying the product CaB2 (composition of Ca - 10% w / w, B - 2% w / w) at different stages of development of culture in season 07/08 in the town of Ituverava - SP. The experiment consisted of eight plots being: pre-bloom, pre-bloom + flowering, pre-bloom + flowering + pod, pre - flowering + pod, flowering, flowering + pod, pods and control, using randomized block experimental design with 8 treatments and 4 replicates perplot. The objective was to analyze which stage of development and strength are more suitable for application of products based on calcium and boron in the soybean crop. Was evaluated in the number of grains per pod, 100 seed weight and number of pods where it was observed that the differences in strengths and development stage of the culture showed no significant differences in application of these products
