Proper irrigation scheduling:
The optimum water quantity must be applied to wheat for reducing water losses. The excess water may cause lodging problem in wheat. However, wheat crop needs 5 to 6 irrigations from sowing to maturity periods. First irrigation should be given after 21 days of sowing and it must not be delayed beyond 21 days, which may cause poor root development. Whereas, subsequent irrigations should be given according to three weeks interval or critical growth stages such as crown root initiation, tillering, flowering and anthesis, grain filling, Milky and grain maturity or dough stages etc. These critical stages need special attention for yield increase with the timely supply of irrigation water needed in proper growth, development and maturity of the crop. The drought condition during different growth stages may decrease tiller number, which can survive to produce grains and may also decrease number of seeds and seed weight per ear that contributes to low yields.
