An experiment was carried in field of Agriculture Research Station, Sakoli, district Bhandara, Maharashtra, India during Kharif 2022-23 season in RBD with PDKV-Sadhana variety, three replication and eleven treatments were taken. The treatment T6 (50:50:50 NPK kg ha-1 as basal dose + 2 foliar sprays of nano urea @ 3 ml l-1 of water at 20 and 40 DAT) was found most effective for increasing the morpho-physiological parameters like plant height, number of tillers per plant, total dry matter production, leaf area per plant, leaf area index and length of flag leaf, while yield and yield attributing characters like total number of grains, length of panicle, number of filled grains, number of unfilled grains, weight of grains panicle-1, number of panicle m-2, grain yield plant-1, grain yield ha-1 over rest of the treatments. NPK consumption ratio has widened from 4:3.2:1 in 2009-10 to 7:2.8:1 in 2019-20, combination of nano urea with basal dose helps in enhancing the productivity of rice without negative influence on plant and the environment.

Based on results, application of 50:50:50 NPK kg ha-1 as basal dose + 2 foliar sprays of nano urea @ 3 ml l-1 of water at 20 and 40 DAT recorded higher morpho-physiological, yield and yield contributing characters. From the enlightment of the study, it can be concluded and recommended that application of 50:50:50 NPK kg ha-1 as basal dose + 2 foliar sprays of nano urea @ 3 ml l-1 of water at 20 and 40 DAT could be a viable option for enhancing the productivity of rice without negative influence on plant and the environment.
