Abstract

                                A study was carried out to determine the relationship between light interception and productivity in rice. Cultivar difference could be observed in leaf area index, leaf angle, light extinction co-efficient (k), dry matter production grain yield. The study suggests that the rice cultivar with optimum leaf area index, upright leaves (low leaf angle) and lower light extinction co-efficient should be screened for higher production potential. Grain yield had negative and significant correlation with leaf angle (r = -0.3710*) and light interception r = -0.3889), the dry matter production was found to have positive and significant (r= 0.3214*) association with grain yield.
