Effect of Tillage and Nitrogen Levels on Yield and Water Productivity of Brassica napus in North West India

In North West India ground water is depleting because of adoption rice-wheat system. Therefore for saving precious resources there need to diversify some area under low requiring crops and adopt techniques. A field experiment was conducted evaluate individual interactive effects deep tillage, irrigation nitrogen rates on yield productivity canola (Brassica napus). Experimental treatments in main plots were combination two tillage systems (deep (DT) conventional (CT)) three regimes (no (I0), one (I1) irrigations (I2)) subplots four ( 0 (N0), 50 (N50), 75 (N75) 100 (N100) kg ha-1 with replications. Maximum rooting depth observed N ha-1. Root mass density upper 60 cm soil higher irrigated whereas below cm, it I0. Higher root recorded DT N100 plots. Dry matter accumulation significantly increased irrigation, application. Seed (10%) I2 (26.2% over I0) treatment. Water improved N100. Oil uptake DTI2N100. at frequency resulted similar frequency. While produced post sowing equivalent that CT irrigations. The results suggest the optimisation high rate canola.
