1.4.6 THE FACTORS THAT INFLUENCE THE ADOPTION OF DRIP
IRRIGATION TECHNOLOGY?
In this section, the factors that influence the adoption of drip irrigation are identified.
Estimation of the factors that determine adoption of drip irrigation is presented in
Table 8. The sample includes 100 farmers both the drip adopters and nonadopters in
the drip and control village, respectively. Given the significance of the coefficients
obtained for the different variables hypothesized to determine adoption of drip method
of irrigation, we have greater confidence in our results.

Figures in parentheses indicate estimated 't' ratios.

It can be observed that the variables AGE, FSIZE, WIDERCROP and NONFARM
are found to be signifi cant determinants of adoption of drip irrigation on the expected
positive line in both the water scarce and surplus regions. These variables are robust in
determining the adoption and extent of drip adoption across regions.
