EFFECT OF NANO DAP ON CABBAGE GROWTH AND YIELD EFFICIENCY

The study on the effect of nano-DAP on cabbage was conducted at the Experimental Farm A.A.U. Jorhat India using 13 different treatments. The highest yield (348.60 q/ha) and benefit-cost ratio (3.64) were observed with the recommended NPK dose. Among the nano-DAP treatments the combination of 100% N & K with seedling root dip and foliar spray recorded a high yield (317.38 q/ha) along with maximum phosphorus uptake. Nano-DAP applications significantly enhanced plant growth yield and nutrient uptake while reducing reliance on conventional fertilizers. These findings highlight nano-DAP as a cost-effective and eco-friendly option for sustainable cabbage cultivation.
