Example text

This should allow the. identification of the farmers’ most critical constraints so that future trials could be more adapted to the identified constraints. A more multidisciplmary approach is required. It is likely that diversifying the &e of animal power will prove important, but more research is, required to identify the key operations and techniques. Failures or negative lessons * - The Work Oxen Project was looking at only one aspect of the farming system. Not enough attention was being paid to the diversity of farniers’ conditions and constraints.

The working principle is as follows. A draft animal moves the frame around a circular wall built of bricks. This brings into motion the car wheel that is supported by the wall. This wheel, in turn, drives the mill by means of a chain drive. The main advantagesof this gear are its comparatively low cost and its simple design. On the basis of current prices, the locally purchased materials to construct the unit cost about US$450, and the mill, imported from Europe, costs about US$250. The output of the mill has been calculated at about 14 kg maize per hour when two grinding operations are carried out (the first grinding 44 produces a rough millmg while the second is more fine).

35% of cropped area. Mixed cropping rice with sorghum, maize, Guinea corn, benniseed, cassava,groundnuts and millet. Animal tractidn history In 1964 two cattle-owning fatmers bought plows from traders from Guinea and started ,to use ox traction (without any assistance from extension agents). In 1967‘a subsidized tractor hue scheme was started and the farmers lost interest in animal traction. Since 1982 tractors have been unavailable for hire, Farmers took a renewed interest in animal traction and they themselves contacted the Work Oxen Project.
