摘要

Sugar cane is grown in Kenana Estate (Sudan) as an irrigated crop using the ridge and furrow system. Cultivation practices for ratoon cane establishment are rather intensive. Conventionally, four to five operations are performed to reform the ridge and furrow system and to incorporate fertiliser in the furrow soil. A ratoon cane field cultivator was designed to accomplish in a once-over manner, required ridge and furrow profiles with granular fertilisers placed and covered at the sides of the furrows, adjacent to the cane rows. Ridge and furrow profiles produced by the cultivator were similar to those produced by Kenana conventional practice. However, with the cultivator, energy in kWh/ha and tractor-hours/hectare to reform the profiles and incorporate fertiliser, were respectively 67% and 30% of those required with the conventional practices.
