Extract

In their response to our paper on the problems of using on-farm trials in efforts to scale-out new crop production technologies and practices among smallholder farmers, Wall et al. (2019) focus on our descriptions of on-farm trials in just one of the three case studies of Agricultural Research for Development (AR4D) projects that were presented. They argue we did not understand the projects’ philosophy and that the biases in farmer and site selection we discussed, do not exist in the southern Africa case study.
