Adubação foliar com cobalto e molibdênio na cultura da soja

Abstract

The biological nitrogen uptake (BNF) of the crop can result in lower costs of nitrogen fertilization, however, the efficiency of the BNF process can be influenced by many nutrients, as is the case of Co and Mo. forms of application of Mo and Co in soybean can be improved and improved. The objective of this work was to determine the effects of the application of Cobalt (Co) and Molybdenum (Mo) on vegetative (V5) and reproductive (R2) soybean (Glycine max L. Merril). The content of chlorophyll, number of pods per plant, number of grains per pod, grain mass and yield are used. In order to carry out the experiment, different dosages of CoMo ® ® fertilizer liquid (Cobalt and Molibdenium) applied in the cultivar BRS 811CRR were applied. The assay was assembled in a randomized block design with five treatments and replicates at each stage, according to the doses written at 50, 100, 150 and 300 mL.ha-1. It concludes that the application of micronutrients cobalt and molybdenum did not increase the content of chlorophyll and the productivity of the culture.
