Desempenho de 10 híbridos comerciais de milho cultivados nas safrinhas de 2016 e 2017 em Sinop-MT

Abstract

Corn is the main crop due to its productive potential and its nutritional composition and Mato Grosso stands out as the main producing state in Brazil. The choice of cultivar is important for the success of the crop, there are many hybrids and varieties available in the market with several characteristics such as productivity, region adaptation, insect resistance among others. Therefore, this work evaluates the performance of 10 commercial hybrids on female flowering, male flowering, productivity, plant height and height of ears in the safer seasons of 2016 and 2017 at Sinop-MT. The experiments were performed at Embrapa Agrossilvipastoril during the months of February to July. The experimental design was in randomized blocks, with three replications. The hybrids were more productive, late and had lower plant height in the year 2017 compared to the year 2016, for height of spikes there was no difference between the years. The hybrid LG 6033 PRO2 was the earliest and the hybrid DKB 310 PRO2, RB 9108 PRO, AG 8061 PRO2, AG 7098 PRO2, P30F53YH and RB 9210 were the later. The genotypes P30F53YH, BRS 1040 and LG 6033 PRO2 were the most productive.
