Description
Summary:This study aimed to evaluate the agronomic performance of six peanut cultivars in conventional and no-tillage systems in the municipality of Marechal Candido Rondon and Tupassi, PR, in the 2011/2012 harvest. The experimental design was in randomized block with four replications in a split plot. Plots were used in two systems of soil management, the conventional and no-tillage system and six peanut cultivars of contrasting growth habit, one of erect and five prostrate, in the subplots. There was no difference between the systems of conservation and conventional tillage on the yield of beans and grains, the number of reproductive structures and in the index grain yield in two evaluated locations. The highest yields were obtained for the Virginia type cultivars independently of the system of soil management, being IAC 503, IAC Caiapo, IAC 213, Runner IAC 886 and Cavalo respectively in Marechal Candido Rondon. In the municipality of Tupassi, grain yield varied only between types of materials branch, and the highest values observed for alternating branching cultivars (Virginia).
