Field experiments were conducted at Agricultural Research Station, Mahatma Phule Krishi Vidyapeeth, Kasbe Digraj, Dist. Sangli, Maharashtra, India during 2014-15 to 2016-17 to study the influence of drip irrigation with deficit irrigation levels and planting layouts on yield of turmeric. Three planting layout {D1: 2 crop lines (30 x 30 cm) on raised beds of 1.2m spacing and 0.6 m top width, D2: 3 crop lines (22.5 x 30 cm) on raised beds of 1.2m spacing and 0.6m top width and D3: 2 crop lines (37.5 x 30 cm) on both sides of 0.75 m spaced ridges and furrows}as main factor and six irrigation levels based on cumulative pan evaporation (CPE) {I1: 40% CPE, I2: 35% CPE, I3: 30% CPE, I4: 25% CPE, I5: 20% CPE and I6: surface irrigation at 75 mm CPE (1.0 IW/CPE ratios)} as sub-factor in split plot design were included for achieving objectives. The results revealed that drip irrigation with scheduling at alternate day of 40% CPE and planting of two rows at 37.5 x 30 cm spacing on both sides of 0.75 m wide ridges and furrows resulted economically better production of fresh and dry rhizome yield with optimum use of water as it recorded significantly highest growth, yield and yield contributing parameters of turmeric. During water deficit condition, drip irrigation scheduled at alternate day of 35% and 30% CPE and planting of two rows at 37.5 x 30 cm spacing on both sides of 0.75 m wide ridges and furrows are also suggested for more turmeric production with less use of water.
