Viabilidade econômica de uso do ácido giberélico na cultura da soja

Abstract

It was intended to analyze the economic viability in the use of Gibberellic acid, in the production of cultivated soybeans, in two soils with different levels of clay, and the production obtained in previous harvests was Proven. The treatments included two sequential applications of gibberellic acid in the dose of 2.0 g per ha, The first one when the crop was in the R1 Stadium and the second in the R2 stadium. The applications were carried out by propelled spray and were considered four scenarios (1: Sandy without gibberellic acid; 2: Sandy with gibberellic acid; 3: clay without gibberellic acid; 4: clay with Gibberellic acid). The collection of data for the construction of the four cash flows was carried out in the property where the study was developed and in the distributor responsible for the sale of the product Package. The methods used to analyze economic viability in each of the scenarios were: Net present value method, internal return rate method and discounted Payback method. In addition, a risk analysis was carried out for the undertaking in question, based on the Monte Carlo simulation Technique. finally, The results found suggest that soybean production under the conditions considered to be economically viable only through the use of Gibberellic Acid.
