Abstract: The field experiments were conducted during rabi seasons 2014-15 and 2015-16 to standardize the drip fertigation system for garlic cv. G-282 in Malwa Region of Madhya Pradesh. The experiment laid out in a FRBD consists of three levels of irrigation water i.e., IW/CPE ratio 0.60 (I1), 0.80 (I2), 1.00 (I3) and three levels of RDF i.e., 60% (F1), 80% (F2), and 100% (F3) and one control plot treatment with three replications. Different drip fertigation treatments significantly affected (P< 0.05) the plant height, polar and equatorial diameter, marketable bulb yield and gross bulb yield of garlic. Among different irrigation and fertigation levels tested, treatment I3F3 recorded highest plant height (74.19 cm), polar diameter (5.41 cm), equatorial diameter (5.08 cm), marketable bulb yield (147.33 q/ha) and gross bulb yield (161.07 q/ha). The maximum WUE was recorded in treatment I1F3 (7.09 q/ha-cm) whereas maximum water FUE was recorded in treatment I3F3 (64.43 kg/kg). The drip fertigation treatment I3F3 gave the highest B:C ratio of 5.60.
