The experiment was carried out in winter season of 2017-18 (November-March) at Instructional Farm, College of Agricultural Engineering and Technology, JAU, Junagadh to study the response of wheat (Triticum aestivum L.) under drip fertigation system. The experiment was undertaken with four fertigation levels viz., 40% RDF-N (F1), 60% RDF-N (F2), 80% RDF-N (F3) and 100% RDF-N (F4) and three irrigation level viz., 0.6 IW/ETc (I1), 0.8 IW/ETc (I2) and 1.0 IW/ETc (I3). Large plot technique was adopted with three replications of each treatment. Fertigation levels and irrigation levels were taken as a main and sub factor respectively. Higher plant height at harvesting, grain yield, straw yield and yield attributes were observed at fertigation level 100% RDF-N and irrigation level 1.0 IW/ETC but, it was found that 0.8 IW/ETC statistically at par with 1.0 IW/ETC. So, optimum irrigation level for wheat under drip irrigation system is 0.8 IW/ETC. Higher fertilizer use efficiency of 84.58 kg/kg was observed at fertigation level 40% RDF-N (F1) combination with irrigation level 1.0 IW/ETc (I3). Higher water use efficiency 17.12 kg/ha-mm was observed at irrigation level 0.6 IW/ETc (I1) combination with fertilizer level 100 % RDF-N (F4).
