A field experiment was conducted during 2001-02 and 2002-02 at Banaras Hindu University to study the effect of row ratio and nitrogen level on rice (Oryza sativa L.) intercropped with ridge planted pigeonpea. Sole crop of rice showed maximum growth, yield attributes and yield. In intercropping system, plant height, dry matter, effective tillers/m, filled grains/panicle, and 1000- seed weight increased significantly in rice when intercropped with pigeonpea in 1:1 row ratio followed by 1:2 ratio while grain and straw yields of rice significantly increased with 1:2 than 1:1 ratio. Growth, yield attributes and yield showed numerical superiority with increasing levels of nitrogen and maximum value was associated with 80 kg N/ha. Row ratio and nitrogen levels in rice had no effect on pods/plants, 100-seed weight, and grain and stalk yields of pigeonpea. Maximum pigeonpea equivalent yield, land equivalent ratio, gross and net return and B:C ratio were attained with 1:2 row ratio.
