A field experiment was conducted during kharif season of 2021 at instructional farm, Barrister Thakur Chhedilal College of Agriculture and Research Station, Bilaspur (Chhattisgarh) to assess the “Effect of Nano DAP fertilizer on Growth and Yield of Rice (Oryza sativa L.)”. The experiment was laid out in Randomized Block Design with seven treatments and three replications. The results revealed that all the growth parameters and yield attributes were significantly influenced by different treatments. Application of 75% RDF of N and P through DAP and Urea as basal + Root Dipping with Nano DAP + two foliar spray of Nano DAP at 25 and 50 DAT significantly increased the growth parameters, yield attributes and yield of rice viz., grain yield (54.78 q ha-1) and straw yield (57.33 q ha-1). In terms of economics of rice cultivation, application of 75% RDF of N and P through DAP and Urea as basal + Root Dipping with Nano DAP + two spray of Nano DAP at 25 and 50 DAT (T7) obtained higher gross income (Rs. 1,48,416 ha-1), net income (Rs. 94,204 ha-1) and benefit : cost ratio (1.74) due to basal application of conventional DAP fertilizer and in later growth stages of crop two foliar application of nano DAP fertilizer increase the nutrient use efficiency as well as yield of rice as compare to other treatments.
