Description A field experiment was conducted during rabi 2OO8-09 season at Hyderabad to
investigate the effect of nitrogen levels and planting geometry on sweet sorghum growth, stalk and grain yields. Application of nitrogen @9O kg/ha gave 49 and. I3% higher biomass, respectively, over 30 and 60 kg N levels. Stalk yield increased by 13.4 % at 90 kg N/ha (25.9 t/ha) over 30 kg (22.88 t/ha), but it was on par with 60 kg N (24.83 t/ha). planting geometry of 30 x 15 cm (high plant density) recorded 106% more grain yield (3600 kg/ha) than 60 x 15 cm (17.50 kg/ha), but it was on par with 45 x 15 cm. Application of 90 kg produced 17.0%/ more grain yield than 30 kg N, but it was on par with 60 kg N. Inter-row spacing of 30 x 15 cm along with 90 kg N/ha produced 31.0% higher grain yield than at 30 x 15 cm with 6o kg N. Higher net returns (Rs. 34,068/ha) and B : c ratio (3.38) were recorded with 30 x 15 cm spacing and 90 kg N/ha.
