Do differences in technical efficiency explain the adoption rate of HYV
2002) provide what is currently the most advanced attempt to get to grips with the adoption of discrete technologies in the presence of spatial autocorrelation, using the adoption of HYV
rice in Bangladesh as an example.
In the 1970s the annual growth rate of HYV
adoption was high at 9%, but it declined to 3% in the 1980s and further slowed to 2% in the first half of 1990s.
and irrigation allowed for double cropping of rice and perennial crops, the rice price appreciated, institutional credit became available and population growth was curtailed from 3 per cent down to 1.

While its predecessor produced such technologies as high-yielding varieties (HYVs
) of cereals that improved the economic outcomes of poor farmers, HYV
adoption, in effect, turned those farmers away from their diverse traditional cropping systems, which had also contained several crops richer in micronutrients than the cereals.
It is now well known that the HYV
cultivation, unless accompanied by adequate water supply, chemical fertilizers, pesticides etc.
The package usually included the HYV
seeds, nitrogen and phosphate fertilizers, insecticides, and fungicides.
I also test whether in fact, among observationally identical households, those in IADP areas were more likely to be using HYV
With irrigation assured in these areas, farmers were offered the HYV
package of seeds, fertilizers, and pesticides at highly subsidized prices.
Adequate and timely supplies of good quality of HYV
of seeds are required to increase agricultural production.
