Abstract:
Variuus components of hydrologic cycle viz. rainfall, run—off, seepage, soil moisture and evapotranspiration (ET) were measured daily in a weighing type lysimeter having undisturbed soil monolith and sensitivity of 0.14 mm of water. Coupea of 12 weeks duration received 1077 mm rainfall and 26 mm irrigation and yielded 471 mm run—off, 243 mm deep percolation averaged for three crop seasons. There was a net gain of 52 mm soil profile recharge. Average seasonal ET was 335 mm. The water use efficiency was 59 green pods for vegetable with 1934 kg/ha pod yield.
