ABSTRACT
It is widely accepted among agricultural researchers that on-farm conditions and farmers’ practices must be closely studied and respected. It is also argued that farmers need to play very active roles in agricultural research and experimentation (Chambers, 1994). It is expected that the participation of the farmers in on-farm adaptive research will result in sustainable development processes more attuned to the farmers’ actual needs and then-indigenous knowledge. This paper is based on work conducted among small-scale market gardeners in Jos-Bukuru area, in which these principles were applied.
