Yields and Water-Use Efficiencies of Dryland Winter Wheat and Grain Sorghum Production Systems in the Southern High Plains
1975
Jones, Ordie R.
Grain yields and water-use efficiencies were compared for conservation bench terraces, bench terraces, and common systems of dryland production of winter wheat (Triticum aestivum L.) and grain sorghum (Sorghum bicolor [L.] Moench). Grain production and water-use efficiency were highest on a bench terrace cropped in continuous grain sorghum. Conservation bench terraces and continuous grain sorghum grown on sloping land also had higher water-use efficiences and grain production than the common dryland systems of wheat-sorghum-fallow on graded terraces and continuous wheat or wheat-fallow on sloping land. The management factors greatly influencing water-use efficiencies were crop selection and land leveling to conserve potential runoff.
