Late October to early November sowings gave maximum yield and irrigation WP of both mulched and non-mulched wheat in NW India.
- class="label">•
Mulch increased yield of late October-early November sowings, but decreased yield of later sowings.
- class="label">•
Mulch reduced the number of irrigations by one in about 50% of years under practical irrigation schedules (∼50% SWD).
- class="label">•
Maximum yield on sandy loam was at 10% SWD and at 10–50% SWD on clay loam, and least irrigation and highest WPI was at 70% SWD scheduling on both soils.
- class="label">•
Maximum WPET occurred with scheduling at 40–60% and 70% SWD on the sandy loam and clay loam, respectively.
