Intervention effect Two hand weedings gave a weed control efficiency of 90.03%.
Intervention effect Two hand weedings gave the lowest weed N depletion, 2.91 kg/ha.
Intervention effect Two hand weedings gave the lowest weed P depletion, 0.45 kg/ha.
Intervention effect Two hand weedings gave the highest wheat grain yield, 4.65 t/ha.
Intervention effect Two hand weedings gave a wheat straw yield of 5.72 t/ha, the highest.
Intervention effect Two hand weedings gave the highest wheat N uptake, 113.7 kg/ha.
Intervention effect Two hand weedings gave the highest wheat P uptake, 28.6 kg/ha.
Intervention effect Two hand weedings gave the highest wheat K uptake, 113.9 kg/ha.
Intervention effect Nitrogen at 90 kg/ha significantly improved weed biomass, weed control efficiency and nutrient depletion over the preceding N levels.
Intervention effect Nitrogen at 90 kg/ha significantly improved wheat grain yield, straw yield and nutrient uptake over the preceding N levels.
Intervention effect The 90 kg N/ha level remained statistically at par with 135 kg N/ha for the measured weed and wheat parameters.
