Eficiência de diferentes estratégias de manejo na maximização do rendimento da cultivar BMX Zeus

Abstract

The need to increase soybean productivity has motivated continuous efforts by researchers and producers, given that the growing global demand for the grain requires solutions that do not depend on the expansion of cultivated areas. This scenario highlights the relevance of adopting strategies capable of integrating productive efficiency and sustainability. Therefore, this study aimed to analyze different technological packages with the potential to optimize crop production per unit area. The experiment was conducted in the municipality of Pato Branco, in the state of Paraná, using a randomized complete block design with three repetitions, and employing the BMX Zeus IPRO (55I57RSF IPRO) cultivar. Eleven nutri-physiological management practices were tested, differing in the use of biological products, biostimulants, resistance inducers, stress mitigators, nutrients, and organic and synthetic hormones, applied with the aim of improving plant physiology, architecture, and resilience to biotic and abiotic stresses. At the physiological maturity stage, ten plants per treatment were collected to evaluate yield components, and at the R8 stage, 4.5 m² per plot were harvested, measuring grain yield corrected to 13% moisture, as well as thousand-grain weight. Among the results, treatment 4 stood out, showing a productivity of 77.4 sc/ha, while treatment 11 (standard) reached 48.4 sc/ha, indicating an approximate 60% increase in grain production. The results demonstrated that the adoption of nutri-physiological management practices provided significant benefits to crop physiology, enhancing the efficiency of resource use and the capacity to respond to stresses, directly reflecting in the maximization of productivity. Thus, the use of technological packages proves to be a viable alternative to increase soybean production efficiency, contributing to meeting the growing global demand sustainably.
