Desempenho agronômico de híbridos de girassol no centro norte de Mato Grosso

Abstract

The Sunflower (Helianthus annuus L.) is a plant that stands out as a promising oleaginous that has shown considerable area overhead and production in the state of Mato Grosso, mainly due to growing demand from the industrial sector, it If so an important economic alternative in rotation and succession of crops in the producing regions of grains and composition of the different systems of production systems, and a further planned and culture, with desirable characteristics from an agricultural point of view, the short cycle, high productivity and high oil production. Among the various sunflower production technologies, proper choice of genotypes is essential to ensure the success of the culture. In order to evaluate the agronomic performance of sunflower hybrids in the North Central region of Mato Grosso, two experiments were conducted in the second season of the years 2013 and 2014, in experimental design of randomized blocks with four replications. The characters evaluated were plant height, stem diameter, number of leaves, number of plants flowering in 57 days, the chapter diameter, average weight of plants per plot, weight of 100 seeds and survival of the final stand. Significant differences were observed among hybrids for agronomic characteristics evaluated.
