Field experiment on wheat (Sonalika) conducted during 1978-79 to 1980-81 with three irrigation schedules (IW/CPE ratio of 0.6, 0.8 and 1.0) and four N rates (0, 60, 120 and 180 kg/ha) at Pantnagar, Naintital [India] indicated that IW/CPE ratio of 1.0 proved better than 0.6 in respect of yield by significantly influencing the spikes/m row length, spike length (except 1979-80) and grains/spike. Application of N affected significantly grain yield, dry matter yield and yield attributes (spikes/m row length, spike length, grains/spike and 1000-grain weight) except spike length in 1979-80 and 1000-grain weight in 1980-81. The optimum level of N was 120 kg/ha.
