YIELD RESPONSE OF CUCUMBER TO DIFFERENT MULCHES AND IRRIGATION LEVELS UNDER DRIP IRRIGATIONN.B. Kanade and H.M. Patil
The experiment was conducted to evaluate different mulches and irrigation levels for cucumber in respect of water requirement field water use efficiency and yield. It was observed that the yield of cucumber was maximum (27.56 t ha') due to adoption of sugarcane trash mulch with irrigation level of 100%, followed by sugarcane trash mulch with irrigation level of 75% (27.55 t ha-'), which were at par. The seasonal water requirement of cucumber under surface method of irrigation was 522.80 cm. In drip irrigation, the water requirement was 128.17, 186.51 and 244.86 mm in the treatments of irrigation levels of 50, 75 and 100% ET respectively, with 74.49, 63.36 and 52.27% of saving of water. The field water use efficiency was maximum (142.88 kg ha-' mm) in sugarcane trash mulch with irrigation level of 75% ET
