Abstract: Abstract This chapter has analysed various aspects of technological change in agriculture, identified the factors that determine the rate of adoption of a new technology and examined the impact of the new technology on productivity growth and resource use in the farming sector. The production functions have been estimated using the Generalised Stochastic Formulation of production functions to capture the input related risks in production. It has explained the effect of risk and uncertainty in production, farm size, risk preference, credit supply and education in the determination of the rate of adoption of a new technology in agriculture. Using the results of econometric analysis this chapter has shown that all the inputs do not increase risk in production. An input that increases mean output does not necessarily increase risk. The rate of adoption of high yielding variety technology is higher in small farms under some favourable conditions. The results show that as a result of technological change, the productivity has significantly increased in Indian agriculture. Irrigation, specially ground water irrigation, has played a crucial role in the technological change and productivity growth. At the same time, excessive depletion of ground water, intensive farming and use of chemical inputs have caused serious damage to natural resources.
