A field experiment entitled “Performance of rice varieties at varying levels of nitrogen under direct seeded upland condition” was conducted on silty clay loam soil with low in available nitrogen, medium in phosphorus and high in available potassium at neutral pH Agriculture College Farm, Rewa (M.P.) during Kharif season 2015. The treatments comprising 3 levels of nitrogen (N1, 40 kg/ha; N2, 80 kg/ha N3, 120 kg/ha) in main plots and 07 (seven) varieties (V1 IET 23824, V2¬ IET 24780, V3 BPT 5204, V4 Sahbhagi,V5 Chittimuthyalu, V6 Kalanamak and V7 IR-64) assigned in subplot of split-plot design replicated three times. The variety IR – 64 gave higher values of most of the growth and yield component characters and resulted significantly highest grain yield (42.98q/ha) in the Rewa region. Application of 120 kg N/ha produced highest growth characters, yield attributing traits and grain yield (45.13 q/ha). The combination of variety IR-64 and 120 kg N/ha was found the best in respect of most of the growth and yield attributing characters along with grain yield (52.14 q/ha) followed by BPT 5204 sown with 120 kg N/ha (47.62q/ha). The net return as well as benefit cost ratio was also highest from the treatment N3V7 (N level 120kg + IR-64) followed by treatment N3V3 (N level 120kg + BPT-5204).
