ABSTRACT
The rice (Oryza sativa L.)-wheat (Triticum aestivum L.) system is one of the important cropping systems of Pu~jab, Pakistan. Both of these crops contribute significantly toward foreign exchange earnings and domestic food consumption. Diagnostic studies of this system conducted by Byerlee et aI. (1984) and Sheikh et aI. (2000) estimated a big yield gap between the potential and actual wheat yields realized by the farmers. Land preparation and planting practices of the rice crop conflicts with the following wheat crop and are determined to be the major yield-limiting factors.
