Scheduling Irrigation in Wheat Grown at Different Seed Rates In
this experiment irrigation scheduling was done on the basis of
cumulative pan evaporation (CPE). Wheat grown at seed rates of
100, 125 and 150 kg ha-1 was irrigated using IW:CPE ratios of
0.70, 0.90, 1.10 and 1.30. Data on agronomic traits like plant
height, tillers m-2, grains spike-1, 1000-grain weight, grain
yield, straw yield, harvest index and water use efficiency were
collected. Statistical analysis suggested that wheat was quite
responsive to increase in irrigation as well as seed rate.
Increase in both treatments displayed an increase in plant
population m-2, which was indicated in terms of tillers m-2. In
other words highest irrigation and seed rate produced greater
plant population m-2 and thus, the competition among plants was
increased. Result was the reduction in important yield
attributes like grains spike-1 and 1000-grain weight, which
ultimately produced less grain yield at higher levels of
experimental treatments. It was inferred
