Abstract

Productivity and profitability of cassava under drip fertigation and rain fed cultivation was worked out, based on the data collected from field experiments carried out at ICAR-CTCRI, Thiruvananthapuram, during the period 2014-15, 2015-16 and 2016-17. The trial was conducted by planting mini setts of short duration variety cassava, “Sree Vijaya†with three levels each of nitrogen and potassium in factorial design along with a control (rainfed crop with soil application of fertilizers). The tuber yield was 2 to 3 times higher under drip fertigation compared to rainfed crop. The mean data over a period of three years indicated that drip fertigation @ 75 kg nitrogen and 125 kg potash resulted in maximum tuber yield, gross and net income and B:C ratio in cassava. Drip fertigation is profitable in cassava, especially in the industrial belts, and N and K @ 75: 125 kg ha-1 could result in 4.4 times increase in net income and 67% increase in B:C ratio.
