(a) WPAET and (b) WPI of peanut under different irrigation and nitrogen application rate treatments [Data points are mean ± standard error, n = 9 (3 × 3; 3 years, 3 replications)]. Bars are standard error. Bars having different letter/s are significantly different at P < 0.05 level according to LSD. AET : actual evapotranspiration; WPAET : water productivity in terms of AET; WPI : water productivity in terms of irrigation water applied. The details of treatments are given in Table 1.
