Abstract: Recently, changes to agricultural practices have constituted a primary focal point for adaptation and change. A field experiment was conducted in the Kharif of 2022 at Agricultural Research Station, Vadgaon Maval, Dist: Pune, to "Study the effect of foliar sprays of nano-urea on growth and quality of transplanted paddy (Oryza sativa L.)". The experiment was set up using a randomized block design with thirteen treatments and three replications. The treatments included sprays of 2% urea, IFFCO nano-urea and COAP nano-urea at 75% and 50% of the recommended nitrogen doses through conventional urea. The recommended dose of fertilizers was 100:50:50 NPK kg/ha. The paddy variety Phule Samruddhi (VDN 99–29) was chosen for the field experiment. The result revealed that the application of foliar spray of nano-urea (liquid) spray with conventional fertilizer had a significant impact on primary growth parameters viz., plant height, tiller number, quality and chemical properties of soil of the field. Further, nano spray (N₇₅PK and N₂₅ through nano-urea) was superior over the rest of the treatment which contributed to the growth parameters of the crop. Spraying of nano-urea can improve the growth contributing characteristics of the paddy and their bioavailability in soil.
