Abstract

This study aimed to compare the performance of upland rice cultivars and experimental lines under no-tillage and conventional planting system, as well as to verify if there was differentiated responses from tested genotypes in the two tillage systems. For so much, two experiments, one under no-tillage and another under conventional tillage, were conducted at Lambari, Minas Gerais State, Brazil, repeated in the 2003/2004 and 2004/2005 growing seasons. Thirteen cultivars/experimental lines were tested. A randomized block design with three replications was used. Grain yield, plant height, flowering, and disease incidence were analyzed. Rice genotypes evaluated showed similar behavior in grain yield in the two tillage systems. In the no-tillage system, there was a tendency for reduction in plant height if compared to the conventional system. It was concluded that the no-tillage system is a feasible alternative for upland rice crop.

KEY-WORDS: Oryza sativa; genetic breeding; planting system.
