An experiment was conducted at the Central Research Station of Orissa University of Agriculture and Technology, Bhubaneswar during summer season of 2015 to study the growth, yield and moisture use of three groundnut varieties under different levels of irrigation (IW/CPE ratio of 1.0,0.8 and 0.6). The experiment was laid out in a split-plot design with three replications. Three Irrigation scheduling IW/CPE ratio (I1- 1.0, I2-0.8 and I3- 0.6) were taken in the main plot and three groundnut varieties (V1- Kadri -6, V2- Devi, V3- Smruti) were assigned to sub-plots. The soil was silty clay having pH 5.45, available N, P and K of (150, 18.5, 107.5)kg/ha, respectively. There was significant variation among irrigation levels with regards to shoot length, branch number, LAI, dry matter production and yield attributes viz. test weight of pod and kernel and shelling percentage were affected by both the factor which in turn influenced the yield. The irrigation level IW/CPE ratio 0.8 recorded significantly higher pod yield of 23.35 q/ha than that of 0.6 and 1.0 due to more number of filled pods (25 per plant) 100 pod weight (59.9 g) and 100 kernel weight (50.0 g). Variety Devi recorded significantly higher pod yield of 23.33 q/ha. which is 28.2% higher than that of variety AKP-7 and 11.5% higher over variety Smruti.
