Urochloa Hybrid Submitted to Biostimulant Application in Grazing Simulation

Abstract

The objective of this work was to evaluate the performance of Urochloa hybrid Convert HD364 applied in different doses as a vegetable biostimulant under grazing simulation in intermittent stocking in the city of Uberlândia, Minas Gerais. The treatments consisted of a control (absence of biostimulant) and in 5 doses of biostimulant, 0.25; 0.5; 0.75; 1.0 and 1.25 L ha-1, in a randomized complete block design with 4 replicates. Productive and qualitative parameters were evaluated. The data were submitted to analysis of variance, using for the comparison of means, the Regression test at 5% of significance. The biostimulant promotes an increase in the accumulation of DM and in the rate of accumulation of forage, leaves and stems of Urochloa hybrid and reduction in the percentage of dead material and the L:S ratio of Urochloa hybrid.

“…The decrease in the L:S ratio may be related to the increasing biostimulant doses, which provided a higher dry matter accumulation in the stems compared to the leaves and, consequently, a decrease was found in this relationship. Lima et al (2019) reported a 5.91% reduction in the L:S ratio when applying 0.75 L ha −1 of biostimulant on forage of the genus Urochloa.…”

“…In this sense, biostimulants have been used mainly in systems that aim for precision agriculture (Oliveira et al, 2019;Lima et al, 2019). Biostimulants are complexes that contain substances such as auxins, gibberellins, cytokinins, and their analogs, which act mainly in the regulation of growth, elongation, and cell division (Santos et al, 2017), favoring the expression of the genetic potential of the plant and, consequently, stimulating the shoot and root system growth (Magalhães et al, 2016).…”
