Abstract

Sunflower crops have a wide adaptability to several edaphoclimatic conditions, with possible alternative for a second harvest. Crops are diversified and extra profit is collected by the producer. Current assay determines the agronomic characteristics of the sunflower genotype planted in second harvest in Campo Novo do Parecis MT Brazil, the main sunflower producing region in Brazil. The assay was conducted on the experimental field of the Instituto Federal de Educação, Ciência e Tecnologia de Mato Grosso, Campus Campo Novo do Parecis MT Brazil, in the agricultural year 2016-2017. Experimental design comprised randomized blocks with 4 replications and 5 treatments from hybrids SYN 045, BRS G40, BRS G49, BRS G50 and BRS G51. The sunflower´s vegetative and reproductive characteristics were evaluated. Hybrids SYN 045, BRS G51 and BRS G40 had good performance in grain and oil. Hybrid BRS G51 showed good performance in grains and oil with reduced cycle and size.
