BIOESTIMULANTE ORGÂNICO, DE ORIGEM PISCÍCOLA, PARA AVALIAÇÃO DO DESEMPENHO FITOTÉCNICO EM DUAS CULTIVARES DE SOJA

Abstract

Soybean is the main oilseed crop in the world, with the Brazilian crop with the highest growth in recent decades, occupying more than 56% of the cultivated area of the country. The increase in production capacity of Brazilian soybeans this coupled with scientific advances and the availability of technologies in the productive sector, one of these advances the use of bio-stimulants. The objective of the study was to evaluate the phytotechnical components of the soybean crop due to the application of organic foliar biostimulant. Before installing the experiment was carried out soil analysis and poultry manure. The experimental design was a randomized block in factorial 5x2, corresponding to five concentrations of the syrup Biostimulant Ferti Peixe® (0, 5, 10, 15 and 20%) in two soybean cultivars (M6972 and M7110 IPRO IPRO) in 4 repetitions. The tillage system was carried out with plowing and harrowing. Cultural practices relevant to the control of weeds, plant pathogens and entomopathogenic were always performed necessary, respecting the technical guidelines for integrated crop management. The results were submitted to analysis of variance, where the description of the variables were performed according to Biostimulant concentrations, performing the polynomial regression, noting the significance of the F test was also performed comparison of means by Tukey test 5% probability among cultivars. It follows that the application of foliar biostimulant to 20% concentration in the nutrient solution had no effect on plant height, pod length and root, pod per plant and seeds per plant. It is recommended the cultivation of genetic material M6972 IPRO to be higher in P100s, income and productivity, applying foliar biostimulant in concentration of approximately 15%.
