Agricultural sector consumes the largest percentage of freshwater to cater to the need for food forever increasing population but the resources like land and water are becoming scares. Therefore, we need to increase water use efficiency by incorporating the modern drip method of irrigation. One of the ways of alleviating water scarcity is by enhancing its use efficiency or productivity. Improving Water use efficiency (WUE) and fertilizer use efficiency in agriculture will require an increase in crop water productivity (an increase in marketable crop yield per unit of water used by plant) and reduction in water losses from the crop root zone. Therefore, this experiment was carried out at Borsi Farm, DauKalyan Singh Agricultural College & Research Station, Bhatapara (IGKV, Raipur) with three different irrigations and fertigation levels to work outcrop water requirement, Water use efficiency and Fertilizer use efficiency. The results of the study revealed that 60 % of cumulative pan evaporation (CPE) water and 80 %water solubilizing fertilizer (WSF) through drip gave the maximum yield of Gladiolus (110119 spikes ha-1) and (110119 corms ha-1), which is 29% more over conventional irrigation. The results also revealed that the water used by the crop was maximum in the conventional method (454.4 mm), water use efficiency was recorded maximum in 60 % CPE water by drip (72.52%), and water-saving also. Similarly, the fertilizer use efficiency (6.39 kg kg-1) and fertilizer saving (73.4%) was observed maximum in 80% WSF by drip.
