Methods for assessing the adoption of rice varieties and land use changes in Chitwan, Nepal, using global positioning system transects and focus-group discussions por Joshi, Krishna D., Khanal, Nabraj, Rawal, Krishna B., Upadhyay, Santosh, Devkota, Krishna P., Joshi, Govind R., Witcombe, John R.

“…The adoption of rice varieties released in the previous 15 years was low except for Sawa Masuli sub-1, a stress-tolerant rice variety that was adopted in 16% of the study area more than a decade after its official recommendation. This variety had the advantage of having similar grain characteristics to the established variety Sawa Masuli, so millers could easily replace it with the new variety. …”
