This paper studies the high adoption of Pusa 44, a long-duration and old rice variety cultivated in Punjab, despite the availability of new short-duration varieties and the overall technological advancement of agriculture. We use farm-household data from a primary survey conducted in 2016-17. Pusa 44 yields on average 2.5 quintals higher per hectare than competing short-duration variety PR 121. It also consumes 16 percent additional water because of its longer duration. As energy for groundwater irrigation is provided tariff-free by the state, Pusa 44 farmers obtain higher net returns even though they pump additional groundwater. Consequently, they have little economic incentive to switch to new shortduration varieties. This varietal stickiness is a pressing policy issue considering the ongoing groundwater crisis in the state. We show that Punjab currently incurs an additional energy-subsidy cost of US$ 49 million per annum on irrigating Pusa 44. Future costs will continue to multiply unless farmers are incentivized to switch to short-duration rice varieties. [ABSTRACT FROM AUTHOR]

In this paper we apply duration analysis to study the factors driving the speed of adoption of a popular Basmati rice variety called Pusa 1121. We use data from a primary survey on variety adoption and crop economics conducted in 2017. The sample comprises of 1305 Basmati growing farmers from the north Indian states of Haryana and Punjab. Pusa 1121 was adopted rapidly by 60% farmers between 5 and 10 years from its release in 2005. Results from the duration analysis highlight the key role of superior quality traits of Pusa 1121 and assured market demand. Access to varietal information from extension agents also shortened farmers' time to adoption. Moreover, we show that early adopters of Pusa 1121 positively influenced other farmers' speed of adoption within their village network. [ABSTRACT FROM AUTHOR]
