Lucrativeness of corn hybrids, in the State of Tocantins, crops 2009/2010

Abstract

This research has aimed to esteem the economic results of different corn hybrids, in the Tocantins State. The experiments were conducted in six environments, which were formed by the combination of among city, date of sowing and nitrogen fertilizer on top dressing. The experimental design, in each environment, was the randomized blocks, and later, its components were submitted the thorough analysis (differentiating environments). At the economic analysis was considered for the purpose of calculation the cost of the inputs, machinery, labor, and other items directly/indirectly that were involved in the production process, and it’s varying only the cost on the seed and nitrogen fertilization. Grain yields at each plot were used to determinate the net income. In average, the best hybrid of each one was classified in the superior statistic group, without statistic difference among them, with 2160 kg ha^-1 (the best simple hybrid), 1915 kg ha^-1 (the best duple hybrid) and 2370 kg ha^-1 (the best triple hybrid). The best simple, double and triple hybrids had shown, in average, good lucrativeness at the experimental condition of this research.
