Foliar fertilizer and biostimulant to enhance performance of Urochloa hybrid in two different seasons

摘要

Technologies that promote forage production provide gains of income in beef cattle. The objective of this research was to evaluate forage production, morphological components and nutritive value of pasture of Urochloa hybrid Convert HD364, with application of biostimulant, foliar fertilizers and urea. A completely randomized design with 7 treatments and 3 replications was used. The treatments consisted of T1 (control: no fertilization), T2 (urea), T3 (Fertmicro), T4 (FertN), T5 (biostimulant), T6 (Fertmicro+biostimulant), T7 (FertN+biostimulant). The leaf content and accumulation of macro and micronutrients, accumulation of dry mass and rate of forage accumulation, concentrations of crude protein, neutral detergent fiber, and acid detergent fiber, morphological components were evaluated. The data were subjected to analysis of variance using the Tukey test at the 5% significance level for the comparison of mean values. The use of foliar fertilizers, nitrogen fertilizer and biostimulant promoted accumulation of forage dry mass, leaf, stem and dead material and higher rates of accumulation of dry mass of stem and dead material of Urochloa hybrid Convert HD364.
