The crops in the shivaliks of Punjab usually suffer water stress under limited and erratic water supply condition. A field experiment was conducted on a sandy loam soils during 2004-05 and 2005-06 to study the effect of tillage and nitrogen management on grain yield, water expense and soil physical properties in maize-wheat cropping sequence under rainfed conditions. The soil of the experimental site is classified as a fine loamy fluventic ustochrept. The treatments of conventional tillage and reduced tillage along with chemical weed control were at par with respect to grain yield of maize. The tillage had no significant effect on grain yield of wheat. 100% inorganic fertilization gave significantly higher maize grain yield over other treatments, while the treatments of 100% inorganic fertilization, and 50% through organic source and 50% through inorganic source were at par with respect to grain yield of wheat. The water expense efficiency was higher under conventionally tilled plots in maize, while in wheat, it was higher in reduced tilled plots with chemical weed control. The infiltration rate, bulk density and nitrogen uptake were significantly affected by different tillage and nitrogen management.
