The study has been carried out on three different crops, viz. maize, banana and groundnut from three blocks, namely Namakkal, Mohanur and Tiruchengode of Namakkal district in Tamil Nadu in 2012 by taking the number of irrigations as risk. The main objectives of the study were to measure risk in farming with reference to cost of cultivation of the selected crops, to derive optimal-input use under different risk farming situations and to determine optimal crop pattern under conditions of risk by an appropriate risk programming model. Quadratic production function which incorporated risk has been used to measure the input choice under different risk situations and linear programming (LP) model has been used to derive the optimum crop choice under given risky condition. According to the quadratic production function outcome, the number of irrigations, which were 11 in normal condition, were reduced to 5 when farmer faced risk in maize crop. Similarly irrigations were reduced from 33 to 23 for banana and from 10 to 7 for groundnut crops in moderate risk situations. The study has concluded that adjusting input use is a way of managing revenue under risk farming situations.
