Agronomic performance of the beet Tall Top Early Wonder as a function of nitrogen and borate fertilization

Abstract

the growth process and root quality. However, few studies are evaluating the influence of the interaction between nutrients in this culture. The objective of this work was to evaluate the effects of the combination of nitrogen fertilization with boron on the production characteristics and quality of the beet Tall Top Early Wonder. The experiment was carried out at the São Manuel Experimental Farm (FCA/Unesp), located in São Manuel-SP. The experimental design was in randomized blocks, with four replications. The evaluated factors were: nitrogen and boric fertilization, in the factorial scheme (2 x 2), totaling 4 treatments: T1 (0 kg ha-1 of N and 0 kg ha-1 of B), T2 (0 kg ha-1 of N and 4 kg ha-1 of B), T3 (90 kg ha-1 of N and 0 kg ha-1 of B) and T4 (90 kg ha-1 of N and 4 kg ha-1 of B). The results showed that there was a positive interaction between nitrogen and boron when applied together, providing increases in productivity and greater uniformity in beetroots.
