The field experiment was conducted during rabi 2014-2015 with CSH-16 sorghum hybrid at Water Technology Center, College farm, College of Agriculture, Rajendranagar, Professor Jayashankar Telangana State Agricultural University, Hyderabad to study the influence of different drip irrigation levels i.e. drip irrigation at estimated 0.6 ETc throughout the life (I1), 0.8 ETc throughout the life (I2), 1.0 ETc throughout the life (I3), 1.2 ETc throughout the life (I4), 0.6 ETc up to flowering 0.8 ETc later on (I5), 0.6 ETc up to flowering 1.0 ETc later on (I6), 0.6 ETc up to flowering 1.2 ETc later on (I7), 0.8 ETc up to flowering 1.0 ETc later on (I8), 0.8 ETc up to flowering 1.2 ETc later on (I9) and in addition to surface furrow irrigation at 0.8 IW/CPE ratio (I10) on economics of rabi sorghum. The results indicated that growing of rabi sorghum was economically viable as net returns and B: C ratio ( . 1, 29,774 and 3.85, respectively) were significantly higher with drip irrigation at estimated ETc of 1.2 throughout the life compared to surface furrow irrigation at 0.8 IW/CPE ratio ( . 96,014 and 3.49, respectively) and B: C ratio was on par with each other (3.85 and 3.49).
