A significant increase in the demand for forage crops has occurred in the Sultanate of Oman due to an escalating demand for meal and milk in the country. Research relative to effective tillage systems for seedbed preparation for increasing the production of forage crops is requisite to meet the rising demand for livestock products. Tins paper discusses the effects of the flat-bed, furrow, and ridge seedbed designs on sorghum production under the harsh arid environment of the Sultanate, The ridge design yielded significantly higher results in the categories of root length, plant height, fresh-weight and dry-weight compared with the furrow and flat-bed designs. Sorghum samples from the sorghum planted in the furrow design had significantly more leaves than samples planted in the flat-bed design. The flat-bed design yielded significantly higher results compared with the furrow design relative to the number of plant tillers, fresh-weight and dry-weight. The value of the additional sorghum fodder produced from the ridged seedbed is considerably greater than the additional costs of the seedbed preparation.
