Abstract
The field experiment was conducted during rabi 2016-17 with CSH – 16 sorghum hybrid at Water Technology Centre, College farm, College of Agriculture, Rajendranagar, Professor Jayashankar Telangana State Agricultural University, Hyderabad. The trail was laid out in a split-plot design with three replications. The treatment combinations consisted of irrigation regimes and fertigation levels (12); Drip irrigation scheduled at estimated 0.8 ETc throughout the crop growth (I1), drip irrigation at estimated 1.0 ETc throughout the crop growth (I2), at estimated 0.8 ETc upto flowering and 1.0 ETc later on (I3) and at estimated 0.8 ETc upto flowering and 1.2 ETc later on (I4) as main-plot treatments and fertigation of 75% recommended dose of (RD) N and K2 O (F1), 100% RD N and K2O (F2) and 125% RD N and K2O (F3) as sub-plot treatments. The RD of fertilizers generally is 100:60:40 kg NPK ha-1 and fertigation was done with conventional fertilizers (N and K2O in 10 equal splits with 7 days interval and entire P2O5 was applied basal soil application). The study indicated that the economics of rabi sorghum was influenced by different drip irrigation regimes and fertigation levels significantly. Gross returns, net returns and B:C ratio ( 1,17,650, 75,119 and 2.76, respectively) were significantly higher with 0.8 ETc upto flowering and 1.2 ETc later on compared to 0.8 ETc throughout the crop growth ( 1,02,047, 61,141 and 2.49, respectively) and on par with remaining treatments. Significantly higher B: C ratio (2.76) was with the fertigation of 100% RD N and K2O than 125% RD N and K2O (2.69) and 75% RD N and K2O (2.63), respectively. Growing of rabi sorghum with drip irrigation at 0.8 ETc up to flowering and 1.2 ETc later on with 100% RD N & K2O is economiclly benefit as net returns and B: C ratio were significantly higher.
