Avaliação de nutrifisiológicos na cultivar de soja BMX titanium

Abstract

Soybean (Glycine max L.) is one of the main agricultural crops in Brazil, whose productivity depends directly on the adoption of assertive management. In this context, the present study aimed to evaluate the agronomic performance of soybean crops subjected to different nutriphysiological managements, involving the application of nutritional inputs, biostimulants, growth regulators and resistance inducers. The experiment was conducted in the field in the municipality of Coronel Domingos Soares - PR, during the 2024/2025 harvest, using a randomized block design with three replications. Six treatments were evaluated (05 nutriphysiological managements and one control). The variables analyzed were: grain yield, thousand-grain weight, plant height, number of branches per plant, number of grains per main stem, per branches, per plant and per square meter. The results showed statistically significant differences only for plant height and number of grains per main stem. The adequate selection of inputs and the correct positioning of applications are decisive factors for the productive success of the crop. Future studies, with better experimental control (lower coefficient of variation), are necessary to indicate management practices that maximize the productivity of the BMX Titanium cultivar.
