Field experiment was conducted during kharif-2017 at Agronomy Research Farm, Narendra Deva University of Agriculture and Technology, Narendra Nagar, Kumarganj, Faizabad, Uttar Pradesh, to study the effect of planting geometry and nitrogen levels on growth of rice (Oryza sativa L.). In this experiment, 4 planting geometry (15x10cm, 15x15cm, 20x10cm and 20x15cm) and 4 Nitrogen levels (0, 60, 120 and 180 kg ha-1) were tested in SPD with 3 replications. The crop received a total rainfall of 804.9mm while the evaporation was 126.1 mm during the entire crop season. The results showed that the plant height, number of tillers m-2, leaf-area index and dry matter accumulation m-2, being at par with 20x15 cm spacing were significantly higher under 20x10 cm than rest of the planting geometry. Nitrogen is also responsible for more leaf area and dry matter production due to higher rate of cell division and cell elongation. The application of nitrogen @ 120 kg N ha-1, being at par with 180 kg N ha-1 significantly improved the plant height, number of tillers m-2, leaf area index and dry matter accumulation m-2 than rest of the Nitrogen levels. The highest grain and biological yields were also noticed at 20x10 cm spacing and 180 kg N ha-1.
