Four were medium-sized producers with wheat plantings between 1 500 and 3 000 hectares, and one was a large producer with a wheat area of 25 000 hectares. There is a selection bias in so far as the interviewees were dynamic producers willing to experiment, seeking to increase their scale of operations, and happy to collaborate in an exercise that might improve their policy environment. The information presented here is mainly based on the 2011 harvest, a record crop year presenting its own special problems, although some interviewees referred to the relatively poor crop year of 2010, and the better harvest of 2009.
