Abstract: Maize (Zea mays L.) is the most versatile crop. It is an important cereal crop for food, feed and fodder. Worldwide, maize is cultivated on 177 million hectare area with total production of 967 million tonnes at a productivity of 5.46 t/ha (USDA, 2013-14). In India, maize is cultivated on 9.43 million hectare area, with production and productivity of 24.4 million tonnes and 2.58 t/ha, respectively (Yadav, 2015). Field experiment was conducted during spring (March-May) 2015 at G B Pant University of Agriculture and Technology, Pantnagar, Uttarakhand. It has been proved by studies that drip fertigation method helps to save water, improve WUE and significant effect on growth parameter of maize. At tasseling stage, 100% CPE irrigation regime produced significantly more number of leaves (13.0) than 60 and 80% CPE irrigation regimes.In drip fertigation, fertilizers applied in desired split dose throughout the growing period according to the crop requirement so that the losses were minimized and opportunity was provided to take more nutrients, which reflected on higher dry matter production in the present study. The dry weight density and volume density of roots increased as the irrigation depth was increased from 60% CPE level to 100% CPE level.
