A coordinated extension approach for maximising returns from mechanical harvesting

A statewide extension program was commenced in 1992, aimed at improving returns from mechanical harvesting by reducing cane losses and minimising dirt levels in the cane supply. The first stage increased industry awareness of cane losses and dirt problems during harvesting and advised ways of reducing losses. Data collected in all districts helped determine the priorities for improving harvesting efficiency. Survey data again showed that cane losses can be quite severe, and also indicated the relative importance of different loss mechanisms. Examples are given of the way in which losses can be reduced and the economic implications of reduced losses. Associated changes in extraneous matter levels for green and burnt cane are discussed.
