Abstract:

A field experimentwas carried out at Precision Farming Development Center (PFDC), at Professor Jayashankar Telangana State Agricultural University, Rajendranagar, Hyderabad. The experiment was laid out in split plot design with three replications. The treatments composes of three drip irrigation levels at 1.0, 0.8 and 0.6 E pan as main plots and four mulches viz., polythene mulch, paddy straw, dried leaves and no mulch assigned to sub plots. The Evapotranspiration production function and water production functions are expressed on the basis of yields because evapotranspiration is related to photosynthesis, which in turn is related to yield of crop. Using an evapotranspiration of 181.4 mm, higher yield of 401.8 kg/ha was obtained for the 1.0 E pan irrigation level, Similarly at evapotranspiration of 145.18 mm, an yield of 336.4 kg/ha was obtained for 0.8 irrigation level and similarly at evapotranspiration of 108.89 mm, yield of 261.6 kg/ha was obtained at 0.6 irrigation level. From these production functions, one can predict yield of a crop corresponding to any level water supplied and can be able to predict any variation in yield due to change in water supplied. After doing the above exercise, there was a need to develop proper irrigation schedules in order to achieve timely application of water as required by the crop at different growth stages. Therefore, irrigation scheduling was done for each yield and corresponding water requirement values. In order to indicate the efficiency of water use at those water availability conditions.
