Abstract

Maize is popularly referred as the "Queen of Cereals” due to its high yielding potential among the cereal crop. The increasing demand along with increments in water and energy costs have made it necessary to develop new technologies for the adequate management of water. With emerging water scarcity, the traditional way of cultivation can no longer be sustained to meet the demands of ever growing populations. Keeping the above facts in view. The field experiment on "Sensor and SMI based irrigation management in Maize [Zea mays (L.)] to enhance growth, yield and water use efficiency” " was conducted during Kharif-2019 at ‘L’ Block, ZARS, University of Agricultural Sciences, GKVK, Bangalore 560065. The experiment comprised of seven treatments viz., T1: Surface irrigation, T2: Drip irrigation at three days interval, T3: Green Soil Moisture Indicator (GSMI) based drip irrigation, T4: Yellow soil moisture indicator based drip irrigation (YSMI), T5: Sensor based drip irrigation at 25%
