A field experiments was conducted under All India Coordinated Sorghum Improvement Project (AICSIP) at 6 lo- cations during the rainy seasons of 2009 and 2010 in a split-plot design having 3 tillage systems in main plots and 4 nutrient-management practices in subplots with 3 replications, to find out their effects on productivity, profitability and energetics of sorghum [Sorghum bicolor (L.) Moench]. Conventional tillage resulted in higher grain yield (3.12 t/ha), N, P and K uptake, net returns ( 23.5 103/ha) and output energy (251 103 MJ/ha) than reduced and mini- mum tillage systems. Application of recommended dose of nutrients (80: 40: 40 N: P O , K O kg/ha) through inor- 2 5 2 ganic fertilizers proved significantly superior in terms of grain yield (3.32 t/ha), net returns ( 26.6 103/ha) and output energy (267 103 MJ/ha) over rest of the treatments.References
