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). Key words: Arachis hypogaea L. soil conservation practice yield components Objetivou-se no presente trabalho avaliar o desempenho agronomico de seis cultivares de amendoim em sistema convencional e de semeadura direta nos municipios de Marechal Candido Rondon e Tupassi, PR, na safra 2011/2012. O delineamento experimental adotado foi de blocos ao acaso com quatro repeticoes num esquema de parcelas subdivididas. Foram utilizados, nas parcelas, dois sistemas de manejo de solo, o sistema convencional e sistema de semeadura direta e seis cultivares de amendoim de habito de crescimento contrastante, um de porte ereto e cinco de porte rasteiro, nas subparcelas. Nao houve diferenca entre os sistemas de manejo conservacionista e convencional no rendimento de vagens e graos, no numero de estruturas reprodutivas nem no indice de rendimento de graos do amendoim, nos dois locais avaliados. No municipio de Marechal Candido Rondon as maiores produtividades foram obtidas pelos cultivares IAC 503, IAC Caiapo, IAC 213, Runner IAC 886 e Cavalo, respectivamente, independentemente do sistema de manejo de solo. Em Tupassi a produtividade de graos variou apenas entre os tipos de ramificacao dos materiais cujos maiores valores foram observados para cultivares de ramificacao alternada (Virginia).
