AB Loss of rainwater through surface runoff and soil erosion is a serious problem related to the rainfed agriculture of Pakistan, mainly as a result of the lack of vegetation, topographic differences, and poor soil structural stability. A field study was conducted to evaluate the effect of tillage on water intake in a clay loam soil with low organic matter content. Three tillage implements-namely, direct drilling, narrow tine cultivator, and moldboard plow in combination with disc barrow—were used for tillage practices. After a few rainfall events following tillage, the cumulative intake and intake rates were significantly lower under tillage treatments where cultivator and moldboard plow were used. Furthermore, vegetative cover and soil crust conditions affected water intake significantly more than bulk density of surface and subsurface soil. Actually, vegetative cover reduced the incidence of soil crusting.
