Abstract
An experiment was conducted in the experimental farm of Anbil Dharmalingam Agricultural College and Research Institute, Trichy to study the effect of barnyard grass (Echinochloa crusgalli) density on growth morphology and yield response of rice (Oryza sativa L.) during the period of February to May 2018. The experiment was laid out in Randomized block design with four replications and five treatments. The pots were filled with field soil. Based on the area calculation in each pot four rice seedlings were transplanted along with different weed densities. The growth parameters viz., plant height, number of tillers and LAI were recorded. The results revealed that the growth morphology of rice was reduced significantly when compared to weed free condition, as there was no competition from the weed species. The growth morphology of the rice plant was reduced gradually from weed free environment to plant with higher densities of barnyard grass. Also found that no growth was seen after vegetative stage of rice. This is because the banyard grass suppresses the growth of rice crop. Hence it is very important to control barnyard grass (Echinochloa crus-galli.) density for the better growth and yield of rice
