A field experiment was conducted on sandy loam soils of Agricultural Research Station, Jangamaheswarapuram during rabi, 2016-17. The experiment was laid out in split plot design and replicated thrice. The treatments comprised of four main plots viz., No irrigation (I1), Irrigation at 0.3 (I2), 0.4 (I3) and 0.5 IW/CPE ratios (I4) and four sub plot treatments viz., foliar spray of 2% urea (F1), 2% DAP (F2), 1% KNO3 (F3) and 2% 19-19-19 (F4) twice at pre flowering pod filling stages. The results indicated that the consumptive use of water and daily soil moisture use rate were significantly affected by irrigation and foliar nutrition treatments and the highest were recorded with irrigation at 0.5 IW/CPE followed by 0.4 and 0.3 IW/CPE ratios. Among the foliar treatments, foliar spray with 2 % DAP recorded the highest consumptive use and soil moisture use rate but on a par with 2 % urea twice at pre flowering and pod filling stages. The highest water productivity was recorded in control plot followed by 0.3 and 0.5 IW/CPE ratios coincided with pod filling (57 DAS) and pre flowering stages (33 DAS). The lowest was recorded with 0.4 IW/CPE coincided with pod formation stage (43 DAS). Foliar application of 1 % KNO3 recorded the highest water productivity which was significantly superior to other foliar treatments.
