FOLIAR APPLICATION OF CALCIUM AND BORON-BASED CALCIUM CHLORIDE AND BORIC ACID MIXED ON INCOME TANK FOR THE EVALUATION OF SOYBEAN SEED.

Abstract

The experiment was conducted in the municipality of Ituverava, in the Estiva farm in the agricultural year of 07/08. The work used the soybean cultivar BRS Valiosa RR to evaluate the performace of the soybean with application of calcium chloride to 26% and boric acid to 17% in different stages of development of culture. The treatments consisted of applications in eight steps, as follows: pre-bloom, pre-bloom + flowering, pre-bloom + flowering + pod, pre - bloom + pod, bloomed, flowering + pod, pods and control. The evaluation used the experimental design of randomized blocks with 8 treatments and 4 replicates. It was evaluated the number of pods per plant, number of grain per pod, weight of 100 grains. It was observed that application of calcium chloride and boric acid by leaf in the different stages of development of soybean showed no significant difference.
