Abstract: A field experiment was conducted at Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C. G.) during kharif season of 2023. The experiment was laid out in split plot design with three replications. The treatment composed of three splitting of nitrogen in main plots (N1-40% (B) + 30% (T) + 30% (PI), N2-50% (B) + 25% (T) + 25% (PI) and N3-30% (B) + 30% (T) + 30% (PI) + 10% (F),) and four different varieties (V1-Vikram TCR, V2-CG Devbhog, V3-Rajeshwari and V4-Protezin in sub-plots. The data revealed that significantly higher grain yield (5.69 t ha-1), straw yield (6.19), protein content (8.62%), nitrogen content and uptake was recorded with nitrogen splitting of 30% basal + 30% tillering + 30% panicle initiation + 10% flowering. Among varieties, Vikram TCR produced higher grain yield (6.19 t ha-1), straw yield (6.76 t ha-1), quality parameters such as milling percent (71.06%), head rice recovery (60.31%), grain length breadth ratio (4.25) and nutrient uptake.
