The concept of Agro-ecological region is a modification and improvement on agroclimatic regions.There is distinction between agro-ecological region and agro-climatic region.Agroclimatic region is a land unit in terms of major bioclimate and length of growing period and which is climatically suitable for certain range of crop cultivation.Agro-Ecological region is the land unit carved out of agro-climatic region when superimposed on landform and soil condition that acts as modifier of the length of growing period.Therefore,within an agro-climatic region there may be a few agro-ecological regions depending on soil condition.This approach has been used in delineating agro-ecological regions of India. In the demarcation of agro-ecological regions of India,the agro-climatic regions of India have been subdivided on the basis of soil type.In the meso regions thus obtained,the length of growing period has been superimposed. This method has resulted into 20 agro-ecological regions.
