Abstract

A field experiment was conducted during the kharif season of 2003-04 to find out the response of rice to different seed densities and nitrogen levels under dry seeded irrigated conditions. Sowing the higher seed densities produced more number of tillers and dry matter production at different growth stages when compared to sowing with 200 seeds m-2. In general application of 100 or 150 kg N ha-1 significantly increased the tiller number and dry matter production at different growth stages. Effective tillers were more in 300 seeds m-2 over 200 seeds m-2. Nitrogen application increased all the yield components. Sowing of 300 seeds m-2 produced higher grain and straw yield than 200 seeds m-2. Application of 150 kg N ha-1 produced significantly higher grain yield than other doses and straw yields were more at 100 kg N ha-1.
