Abstract: A experiment entitled “Performance of rice varieties at different levels of nitrogen under direct seeded upland condition” was conducted during rainy season of 2017 at the JNKVV college of agriculture instruction farm, Rewa (M.P.). Objective of this experiment was to find out Performance of rice varieties at different levels of nitrogen under direct seeded upland condition. The experiment was laid out in a split plot design with four replications. The treatments comprised twelve varieties IET-24797(V₁), Gotra Bidhan (V₂), PR 124(V₃), juit (V₄), Sahbhag (V₅), PS-5 (V₆), DRR Dhan 43 (V₇), PS-3 (V₈), JR-767(v₉), JR -81 (v₁₀), US 314 (v₁₁) and IR -64(v₁₂) and three nitrogen levels (50, 100 and 150% RDF i.e. N₅₀, N₁₀₀ and N₁₅₀). The experiment were sown on 03 July, 2017 keeping a seed rate of 50 kg/ha and row spacing 30 cm and plant spacing 10 cm. the fertilizers were applied as per treatment. Among the variety IR-64 gave higher values of most of the growth and yield component characters and resulted in significantly highest grain yield (45.61 q/ha) and net income Rs. 57237/ha. Application of 150 kg N/ha produced highest growth characters: yield attributing traits and grain yield (37.70 q/ha) and net income (Rs. 46065/ha). The combination of variety IR-64 and 150 kg N/ha was found the best in respect of most of the growth and yield attributing characters along with grain yield (53.91 q/ha) followed by US-314 sown with 150 kg N/ha (47.90 q/ha). The economics of treatment 150 kg N/ha and variety IR-64 was also found the most net income Rs 77184/ha and B: C ratio 4.12.
