BIOINSUMO NA CULTURA DA SOJA

Abstract

The use of bio-inputs in soybean cultivation has become increasingly important for achieving high productivity, reducing costs, and environmental sustainability. Bioinputs are products derived from living organisms that can aid in plant development, increasing resistance to diseases, pests, and abiotic stresses. This study was carried out with three different biological input treatments (on-farm, commercial, and control) in soybean cultivation under conventional farming practices on a rural property in São Gabriel de Goiás, Goiás, Brazil. Results obtained in this study showed that the use of bio-inputs can bring significant benefits to soybean cultivation for parameters such as flowering, nodulation, and productivity. The treatment with commercial inoculant presented a production of 85.2 bags per hectare, while the on-farm treatment, which used bio-inputs produced on the property, achieved an even higher productivity of 93.5 bags per hectare. The control treatment, which did not use bio-inputs, showed lower productivity of 45.1 bags per hectare. Furthermore, data on flowering and harvest indicated a statistically significant difference among treatments. The on-farm treatment presented more accentuated flowering and higher number of secondary nodules compared to the control and commercial treatments. For the count of the number of pods and number of grains per pod, the results were more positive for the on-farm treatment, where a higher number of pods with three to four grains were obtained. It can be concluded that the use of bio-inputs was positive in various parameters in soybean cultivation, particularly in productivity, demonstrating the importance of bioinputs and the need for more studies to support their use in cerrado agriculture.
