Viabilidade econômica da cultura do milho (zea mays) e do feijão (phaseolus vulgaris) sob baixos índices pluviométricos no município de Uruçuí

Abstract

The Cerrado region of Piauí presents adequate edaphoclimatic conditions for the production of grains. In the 2015/2016 harvest, the area devoted to grain cultivation represented 2.34% of the planted area in Brazil and 17.48% of the planted area in the northeast. The process of price formation of maize and beans depends directly on factors related to regional and national supply, adequacy of supply to the market, flow of exports and imports, demand and mainly climatic conditions. The corn crop is the second most cultivated considering the first and second crops, and the third most cultivated bean, accounting for both harvests in Piauí. The objective of this work was to evaluate the financial return in two seasons of sales (May and October) in corn and bean crops in a year of low rainfall in the Uruçuí - PI region. The experiment was carried out in the municipality of Uruçuí - PI, in the experimental area of the Federal Institute of Piauí (IFPI), from January to May 2016. The experimental design was subdivided into three (3) Cultivars, one for the corn crop and two for the bean crop, the split-time sub-plots: May and October, composed of 3 (three) replicates, the variables analyzed were productivity, revenue and profit. Based on the results obtained, it was observed that cowpea cultivation provided better economic results in relation to maize crop. For the marketing season, October was superior for cowpea, but did not differ statistically from May for maize.
