A field experiment was conducted in a microwatershed established with subabool (Leucaena leucocephala) keyline as vegetative barrier on sloping land on Parbhani (Maharashtra, India) to evaluate its performance with respect to soil erosion control, rain water conservation and increase crop production. The leucaena keylines were established at 0.25 m and 0.50 m vertical interval. Two recommended package of practices pigeon pea+sorghum and pigeon pea+soyabean were tested. The vegetative keyline at 0.25 m VI gave maximum net monetary returns under both intercropping systems. Monetary returns were less in crop without keyline. The treatments of vegetative keyline established at 0.25 m vertical interval recorded minimum runoff of 7.75% and treatment of vegetative keyline 0.5 m vertical interval recorded runoff of 11.14%. Maximum runoff of 19.675% was recorded in the control treatment. The minimum soil loss of 1.51 t/ha was recorded under keyline at 0.25 m VI as against 2.70 t/ha in the control. The pigeon pea+soyabean intercropping system recorded minimum soil loss of 1.68 t/ha. The highest soil moisture use (550.13 mm) was recorded by pigeon pea+soyabean with combination of leucaena keyline at 0.25 m vertical. The vegetative keyline reduces soil erosion from cultivated field and increases the water use and water use efficiency.
