An experiment entitled “Effect of integrated nutrient management (INM) on rice (Oryza sativa L.) was conducted at Regional Research Technology Transfer Station, G. Udayagiri Kandhamal, Odisha during July-November months of 2020-21. The experiment consisted of twelve treatments, was laid out in Randomized Block Design with three Replications. The grain and straw yields of the rice crop were noted, including panicle length (cm) and plant height. that grain yield due to various treatments ranges from 25.0- 33.3q ha-1. lowest yield was 25.0 q ha-1 observed in control where no nitrogen applied. Highest yield was recorded 33.3q ha-1 due to 100% Nitrogen dose. The yield was increased by only 15% over control due to addition of 50% N dose of 28.9q ha-1. Use of Azospirillum, Dhanicha, glyricidia leaf and Lantana camera significantly increased the yield by 8.0, 9.6, 14.8 and 6.8% respectively over control. However, addition of 50% N with the above treatment resulted in 17.6, 22.0, 24.8 and 16.0% increase over control respectively. Out of various green manures, glyricidia leaf was found more efficient by increasing the yield by 14.8% over control which is comparable to the application of 50% N in inorganic form. So far as application of full recommended dose of N is concerned it resulted highest yield of 33.3 q ha-1 which is followed by the yield of 31.2q ha-1 of 50% N through glyricidia leaf + 50% N s inorganic form.
