BIOINSUMOS APLICADOS VIA FERTIRRIGAÇÃO NA MELHORIA DA QUALIDADE BIOLÓGICA DO SOLO NA CULTURA DA BANANA

Abstract

Banana cultivation represents one of the most economically, socially, and nutritionally relevant fruit-growing activities in tropical and subtropical regions, standing out for its high income- generating capacity and the nutritional importance of the fruit. However, phytosanitary limitations, especially those related to soil-borne pathogens and phytoparasitic nematodes, have compromised the productive sustainability of the crop in different producing regions. In this context, the use of bio-inputs has been considered a promising strategy within sustainable agricultural systems. This study aimed to report the experience of applying *Trichoderma harzianum*, *Bacillus subtilis*, Bokashi, and efficient microorganisms (EM) via fertigation in a micro-sprinkler system, in an experimental area cultivated with different banana genotypes at the Instituto Federal Goiano, Urutaí Campus. The experiment was conducted with a spacing of 2 × 2 m, using cultivars from the Prata, Cavendish, Maçã, and Terra groups. Applications began in 2024, with a six-month interval, using a microbiological concentration between 10⁸ and 10⁹ CFU mL⁻¹ and a dose of 2 L ha⁻¹. Evaluations were carried out based on visual field observations and chemical, physical, and biological analyses of the soil. The results indicated a soil environment favorable to microbial development, with good chemical fertility, high enzymatic activity, and visual improvement of the root system. The data suggest that the integration between soil fertility, microbial diversity, and continuous application of bioinputs can contribute to more resilient and sustainable production systems.
