Stopping go®฀ como estratégia de redução do acamamento e potencialização da produtividade do feijão caupi

Abstract

The use of products that stimulate the natural processes of plants has been shown to be indicative of an agronomic technique that enhances the productivity of agricultural crops and reduces lodging. The aim of this study was to evaluate the effect of the application of doses of the amino acid-based biostimulant (Stopping Go®) applied at different stages of vegetative development of cowpea on the yield and lodging components. The study was conducted in an irrigated field at the ACCERT Experimental Station - Piquizeiro Farm, in Balsas/MA. The experimental design used was randomized blocks, in a 5x2 factorial scheme, using 5 doses of the products (Stopping Go® at doses of 0; 125; 250; 500 and 750 mL ha-1) and 2 development stages (V2 and V4), with 4 replicates, totaling 40 plots. The applications occurred at the study stages of the cowpea cultivar BRS Guariba. Plant height, lodging, and injury (phytotoxicity) were assessed at 7, 14, 21, and 28 days after each application (DAA) of Stopping Go®. At harvest, branching, number of pods per plant, number of grains per pod, thousand-grain weight (PMG), and productivity were assessed. After obtaining the data, they were subjected to Statistical Analysis of Variance (ANOVA), and for variables that presented significant differences, the F test was performed at a 5% probability level. The data were analyzed using R Software (Version 4.3.2). The use of Stopping Go® does not interfere with the architecture, yield, and productivity components
