INTERPAKS, Examines the adoption of high yielding varieties (HYV) in India, especially in the context of micro-scale planning within HYV programme. Planners working the implement acceptance of HYV assumed that innovated inputs are adapted simultaneously and at the correct levels of intensity when, in fact, this does not occur. Adoption rates vary greatly between innovations and between areas; position of innovations is low on the acceptance curve; by 1969 only an average 12% of all participants adopted correct acceptance of fertilizer, pesticide spraying, nursery cultivation of paddy and improved plowing practices. In addition, it is not the same 12% who adopt all improved practices. Reasons given for not adopting are: input cost, lack of control over irrigation, excessive risk, lack of information, not enough labor, and unavailability of inputs. Of these, the first three are most salient. Lack of rainfall and adequate storage facilities are additional barriers to adoption.
