A field experiment was conducted over two years (1979 and 1980) to investigate the effect of seeding rates, sowing methods and manure and urea applications on the performance of forage sorghum {Sorghum bicolor (L.) Moench} var. Abusabein grown on a saline-sodic soil in the Sudan. The results revealed that planting on shoulders of the ridge is a superior practice to avoid salinity hazards affecting the early stages of growth. More plants per unit area and higher yields were recorded on plants grown on shoulders of the ridge compared to those grown on top of the ridge. The application of farmyard manure alone or in combination with urea to salty soils significantly increased forage fresh and dry yields and improved forage quality.
