Crop zoning refers to the specific regions/areas of potential crop and cropping sequences which are biophysically suitable and also have high productivity. Potential crop zones have similar geographic setting in terms of soils, landforms, rainfall, temperature, length of growing period, irrigation potentials. Actually, crop zoning facilitates better utilization of land and water resources thus providing opportunities to harvest full potential of the crops if grown in areas specified as suitable, which in turn derive maximum economic benefit.

The crop zoning can be conceptualized in the context of optimizing crop production through judicious use of land and water resources. Prevent degradation of the environment and to maintain in such a way that the resources of the environment are put to their most beneficial and optimum use while at the same time conserving them for the future. The purpose of crop zoning is to make best and sustainable use of scarce land and water resources for crop production. Crop zoning is particularly supportive for the decision making process concerning land use planning.
