In most of the developing countries where irrigated cropping is widely practiced, a number of common problems emerge such as low yields, salinity of the soil, deteriorating soil structures, ground water depletion and water scarcity. In the rice-
wheat belts of Pakistan and India, one innovative approach to address these issues is raised cropping beds (Page 2005). Beds are formed with narrow trenches between the beds serving as access and left in place for up to five years. Crops are planted into these beds.
In Pakistan, three types of beds are introduced for optimal production; namely wide beds, narrow beds and flat basin seed beds. With rabi wheat, the crops have been seen to have superior growth on raised beds than in traditional flat irrigation basins, ttere is also the advantage ofhaving less salt in the crop root zones after a few planting seasons.
