Growth and yield of wheat with boron applications

Abstract

The deficiency of the micronutrient boron (B) stands out for the losses related to the formation and quality of the harvest. It is essential the comprehension about B fertilization and its application in the grain crops. The aim of the study was evaluating the growth and yield of wheat in response to different levels and forms of application of boron micronutrient. The experimental design was randomized blocks, and the four evaluated treatments were: control without addition of B; furrow fertilization (sodium octaborate 20.5% B, 1.0 kg.ha-1); leaf fertilization (sodium octaborate 2% B, 150 mL.ha-1) and furrow + leaf fertilization (1.0 kg.ha-1 sodium octaborate 20.5% B + leaf 150 mL.ha-1 of sodium octaborate 2% of B). The lenghth of root system and aerial part, dry mass of the plant and yield of grains were evaluated. The fertilization with furrow and leaf boron provided an increment of 56.5% in the grain yield than those plants without this micronutrient application. The application of B furthered the growth and yield of the wheat, being recommended its furrow and leaf application in the fertilization of this crop.
