Produtividade do arroz de terras altas após o cultivo de plantas de cobertura no cerrado goiano

Abstract

This study aimed to evaluate the effect of different cover crops on the production of upland rice under no tillage system (NTS) and conventional soil management (CS), both under organic production system. It were used as cover crops pigeon pea, mucuna and crotalaria, and sorghum and fallow (spontaneous vegetation) as control treatment. The experimental design was a split- plot completely randomized blocks with four replications. It were determined the number of tillers, panicles and grain yield of upland rice. The plots under NTS were completely destroyed by termites, which made impossible to collect data under this system of soil management. Under CS, the number of panicles and grain yield was higher when rice was cultivated after crotalaria, pigeon pea and mucuna, and lower when cultivated after sorghum and fallow.
