The experiment was carried out at Instructional cum Research Farm, IGKV, Raipur (C.G.) during kharif season, 2018 to study the Effect of Nitrogen levels on Growth, Yield attributes and Yield of red rice cultivars (Oryza sativa L.). The experiment consisted five red rice cultivars (Bantha luchai, Shrikamal, Kankadiya, Khuddi and Jyothi) in main plot and four nitrogen levels (0, 60 kg N ha-1, 80 kg N ha-1 and 25 kg N ha-1 + LCC based nitrogen management) in sub plot under split plot design with three replications. The result revealed that among cultivar, maximum plant height was recorded by Shrikamal. Maximum number of tillers hill-1, number of leaves and dry matter accumulation was observed in Jyothi variety. Maximum number of effective tillers hill-1, panicle weight, test weight and grain yield were recorded under variety Jyothi. However, higher growth, yield attributes and grain yield were recorded by the application of 80 kg N ha-1. Straw yield was not influenced by cultivars but affected by nitrogen levels. Significant interaction effect was noted on plant height, number of tillers, effective tillers and grain yield. Harvest index of red rice cultivars were not affected significantly due to different cultivars and nitrogen levels.
