<P> Green revolution spread only in irrigated and high - potential rain fed areas . The villages or regions without the access of sufficient water were left out that widened the regional disparities between adopters and non-adopters . Since, the HYV seeds technically can be applied only in land with assured water supply and availability of other inputs like chemicals, fertilizers etc . The application of the new technology in the dry - land areas is simply ruled out . </P> <P> The states like Punjab, Haryana, Western UP etc. having good irrigation and other infrastructure facilities were able to derive the benefits of green revolution and achieve faster economic development while other states have recorded slow growth in agriculture production . </P> <P> The new agriculture strategy involving use of HYV seeds was initially limited to wheat, maize and bajra . The other major crop i.e. rice responded much later . The progress of developing and application of HYV seeds in other crops especially commercial crops like oilseeds, jute etc. has been very slow . In fact, in certain period a decline in the output of commercial crops is witnessed because of diversion of area under commercial crop to food crop production . The basic factor for non-spread of green revolution to many crops was that in the early 1960s the severe shortage in food grains existed and imports were resorted to overcame the shortage . Government initiated green revolution to increase food grain productivity and non-food grain crops were not covered . The substantial rise in one or two food grain crop cannot make big difference in the total agricultural production . Thus new technology contributed insignificantly in raising the overall agricultural production due to limited crop coverage . So it is important that the revolutionary efforts should be made in all major crops . </P> <Ul> <Li> "The Great Gene Robbery" by Claude Alvares </Li> </Ul>
