Abstract:
The major problem in cotton-wheat cropping system is delayed harvesting of cotton
which results in late planting of wheat. Therefore, a field experiment was conducted on relay wheat in
standing cotton that comprised of three different seeding densities (100, 125 and 150 kg ha-1
) and four seed soaking durations (0, 6, 12 and 18 hours). The experiment was designed in randomized complete block design with factorial arrangement having three replications. The interactive effect of seed rates
and seed soaking duration on emergence count, leaf area index, spikelet’s per spike, grains per spike
and grain yield were significant. Wheat sown with seed rate of 150 kg ha-1 and 12 hrs of seed soaking
produced significantly higher yield than all other combinations except for 125 kg ha-1 seed rate and 12
and 18 hrs of seed soakings. In conclusion, the productivity of relay wheat in standing cotton can be
enhanced by using seed rate of 150 kg ha-1 along with seed soaking duration of 12 hours.
