Morphological traits associated with competitiveness in rice

Production of rice suffers a vital misfortune through weed pressure worldwide. The present work was carried out to evaluate ten rice plant characteristics related with the competitiveness against weeds. The experiment was conducted in a split-plot design with the weedy and weedfree treatments in the main plot and ten rice genotypes as the sub-plot treatment. Results depicted that rice genotypes reveal variable competitiveness against weeds. Among the genotypes, highest competitive rate was found in Govind and UPR 2962-6-2-1. The competitive ability of these genotypes could be attributed to high leaf number tiller number, plant height and shoot biomass at flowering stage. From the study we could understand that morphological parameter can be presuppose to be applied as suitable trait in rice weed interaction for sustainable agriculture
