A field experiment was conducted to study the uniformity of water application, fertilizer urea distribution and response through green pod yield of pea (Pisum sativum var. Lincoln) when drip system was used for irrigation as well as urea application. The statistical uniformity coefficients for the drippers calculatedfor 1990–91 and 1991–92 were found to be 90±3 per cent and 88 ± 3 per cent in the beginning and 89 ± 3 per cent and 89±3 per cent at the end of experiment, respectively. Highest green pod yield (95.5 and 98.1 q ha−1) were recorded in the treatment where the fertilizer was applied in split doses through drips. The magnitude of yield response to fertilizer application was also maximum in the treatment. Urea applied through drips was found more uniformly distributed through out the soil depth up to 0.90 m.
