Due to overexploitation of available water resources, it has become very important to develop new technologies and methods of irrigation that can be helpful to utilize this precious input in an effective way. An experiment was conducted to determine water requirement and response of maize varietiesVIVEK QPM-9, PEEHM-5, HQPM-1 and HQPM-5 to irrigation at 50% soil moisture depletion (SMD) level. Moisture contents were recorded from a root zone of 90 cm (from five depths viz., 0 – 15, 15 – 30, 30 – 45, 45 – 60 and 60 – 90 cm) for irrigation. Data on climatic parameters was also recorded for the growing period. The results indicated thatyield was significantly affected by no. of irrigations as well as varieties. All the varieties gave significant response up to two irrigations (I2) only. The total amount of water applied up to two irrigation was 50. 7cm including effective rainfall. The yield obtained at irrigation level (I2) for variety VIVEK QPM-9, PEEHM-5, HQPM-1 and HQPM-5 is 5.5t/ha,5.2t/ha, 6.3 t/ha and 5.8 t/ha, respectively.
