Avaliação do desempenho agronômico do capim Mombaça, submetido a aplicação de bioestimulante foliar

Abstract

The degradation of Brazilian pastures is one of the main factors responsible for the reduced productivity of animals raised on pasture. Thus, the search for alternatives that make degraded pasture areas viable and increase productivity is a constant in the scientific community. The application of biostimulants is a viable technology to promote satisfactory effects on forage development, resulting in increased production and conservation of pasture areas. The objective of this work was to evaluate the use of commercial biostimulant, DNA Pastagem, on the morphology and mass accumulation of Mombaça grass. The analyzed variables were leaf natural matter weight (MNF), root natural matter weight (MNR), leaf dry matter weight (MSF), root dry matter weight (MSR), leaf height (AF) and stem length root (CR). A completely randomized experimental design was used and the treatments consisted of the application of doses corresponding to 0%, 100%, 200% and 300% of the dose recommended by the manufacturer, applied 60 days after plant emergence and evaluated at 30, 60 and 90 days after application of the product. The use of biostimulant composed of humic substances, amino acids and nutrients, promoted leaf growth, accumulation of natural and dry matter of the Mombaça grass. The use of the commercial dose was the one that presented the best development of the evaluated components, 90 days after application.
