e0“2 hand-weedings 15 and 30 days after sowing (DAS) in maize and application of metribuzin (200 g/ha) at 30 DAS in wheat significantly reduced weed density, biomass and recorded significantly higher yields of maize and wheat respectively, over weedy check in both maize and wheat”

- Intervention effect Maize weed density and biomass were statistically at par under continuous and rotational conventional tillage.
- Intervention effect Maize grain and stover yields were statistically at par under continuous and rotational conventional tillage.
- Intervention effect Wheat grassy weed density and biomass were lowest under continuous zero tillage following zero or conventional tillage in maize.
- Intervention effect Tillage treatments had nonsignificant effects on wheat broadleaf weed density and biomass.
- Intervention effect Tillage treatments had nonsignificant effects on wheat grain and straw yields.
- Intervention effect Two hand weedings at 15 and 30 days after sowing raised maize yield versus a weedy check.
- Intervention effect Metribuzin at 200 g/ha reduced wheat weed density and biomass versus a weedy check.
- Intervention effect Metribuzin at 200 g/ha raised wheat yield versus a weedy check.
- Intervention effect Zero tillage in maize with conventional tillage in wheat gave the highest benefit to cost ratio.
- Intervention effect Zero tillage in maize with conventional tillage in wheat gave the lowest cultivation cost.
- Intervention effect Atrazine in maize plus metribuzin in wheat gave the highest benefit to cost ratio among weed management practices.
- Intervention effect Atrazine in maize plus metribuzin in wheat gave the highest net returns among weed management practices.
- Intervention effect Tillage and weed management did not influence soil bulk density at the end of the cropping cycles.
