However, it is generally associated with straw mulching of the soil, which excludes straw-baling and stubble grazing by sheep. In the Northern Negev of Israel (250 mm of rainfall), during three years of drought, the yield of wheat grain was increased more than 40 per cent by no-till management, but straw mulching had no additive effect. During a “favorable year” (284 mm of rainfall), no effects on grain yield and quality were found for no-till or straw mulching. Dry Awassi ewes consumed daily 1 kg of wheat stubble, less than their requirement for maintenance. Energy expenditure, measured by the heart rate method, was 20 per cent higher in sheep grazing stubble than those fed an iso-energetic diet distributed indoors. Stubble grazing was economically profitable to both wheat growers and sheep-breeders.
