A field experiment was conducted on sandy loam soils of Agricultural Research Station, Jangamaheswarapuram during rabi, 2016-17 to study the effect of irrigation and foliar nutrition on growth, yield and nutrient uptake of blackgram. 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 IW/CPE (I2), 0.4 IW/CPE (I3) and 0.5 IW/CPE (I4) ratios and four sub plot treatments viz., foliar spraying of 2% urea (F1), 2% DAP (F2), 1% KNO3 (F3) and 2% 19-19-19 (F4) twice at pre-flowering pod filling stages. Among the main plot treatments, irrigation given at vegetative stage (33 DAS) i.e, 0.5 IW/CPE ratio was found to be better in improving growth, yield parameters and more nutrient uptake over other irrigation treatments. Among, sub plot treatments 1% KNO3 twice at pre-flowering and pod filling stages (F3) recorded significantly the highest growth and yield of blackgram when compared with other foliar treatments.
