Agronomic characteristics and seed physiological quality of common bean cultivars fertilized by foliar application of calcium and boron

Abstract

A research was carried out at Botucatu (SP), Brazil, with the objective of evaluating the influence of calcium and boron foliarly applied to the plants on productivity and physiological quality of seeds of two common bean cultivars. The experiment was set up according to a randomized complete block design, in a factorial arrangement of 2 x 4 and four replications, with treatments represented by common bean cultivars Pérola and Campeão 2 and four doses of the foliar fertilizer (D – without application; D2 – .5 L ha- (5 g ha- Ca + 0.75 g ha- B); D3 – 3.0 L ha- (30 g ha- Ca + .5 g ha- B), and D4 – 4.5 L ha- (45 g ha- Ca + 2.25 g ha- B). The results showed that the foliar application of Ca + B improved yield of Pérola and seed vigor of both bean cultivars.
