Intervention effect Residual 5 and 7.5 kg/ha Zn applications significantly affected wheat yield attributes and yield.
Intervention effect Direct 5 kg/ha Zn on wheat performed at par with residual 5 and 7.5 kg/ha Zn on cotton.
Intervention effect The 2.5 kg/ha Zn treatment raised 2013–14 wheat grain yield 12.6% over control.
Intervention effect The 5 kg/ha Zn treatment raised 2013–14 wheat grain yield 12.3% over control.

Intervention effect Residual 7.5 kg Zn/ha to cotton enhanced system productivity 9.9%.
Intervention effect Increasing Zn levels to cotton significantly enriched wheat grain and straw Zn.
Intervention effect Cotton establishment methods significantly affected wheat-straw Zn content and uptake but not wheat-grain Zn.
Intervention effect Cotton establishment methods had nonsignificant effects on system production and economic efficiency and profitability.
Intervention effect Zn levels up to 5 kg/ha increased system production and economic efficiency.
Intervention effect Residual 5 and 7.5 kg Zn/ha applications to cotton produced significantly higher net returns and benefit-cost ratios.
