RESUMO:

The use of biostimulants in banana farming is an alternative to reduce the amount of nonrenewable inputs in Amazonian agroecosystems, as well as improve the economic return of the activity. Thus, the objective was to study the effect of inoculation of microorganisms combined with fertilizer doses on the production of silver banana, and to analyze the economic viability of the technology. A biostimulant (BIO) based on two microorganisms, Trichoderma asperellum (Ufra-06, Ufra-09, Ufra-12 and Ufra-52) and Bacillus subtilis (Ufra-92) were used. The experimental design was completely randomized blocks with four blocks and 4 plots per treatment. Three treatments were used: 100% F (control), with 100% fertilizer dose, without biostimulant; 50% F + BIO, with half the dose of fertilizer plus biostimulant and; 100% F + BIO. The planting was carried out under field conditions in the municipality of Ourém. The experimental period considered the implementation, formation (2018) and first year of production (2019). The first production was evaluated through the characteristics of the bunches and fruits, and the parameters bunches per clump and fruit yield. Economic viability was studied from the analysis of production costs as well as economic indicators (PN, IRR, NPV, B / C, C / B) resulting from a six year cash flow. Biostimulant inoculation plus 50% of fertilization promoted a production performance similar to 100% F. The three nutritional managements are economically viable, however 50% + BIO is more profitable, returning the invested capital faster. Therefore, T. asperellum and B. subtilis biostimulant can be used to reduce the amount of synthetic fertilizers in the production of silver banana, being an economically viable technology, 30% more profitable than conventional nutritional management.
