In a field study on a Wynona silt loam soil (Cumulic Haplaquolls) the effects of tillage and row spacings on soil water content and yields of monocropped (MC) and double-cropped (DC) wheat and grain sorghum under rain fed conditions were investigated. For the double-cropped treatments, the water content in 120 cm of soil profile was not significantly affected during the grain sorghum growing period by tillage or row spacings; however, tillage and planting operations must be timely to prevent loss of water in the soil-seed environment when attempting to establish a stand for the double crop. For the 3 years of successful double-cropping, an average of only 12 percent of the precipitation that fell from mid-June (after wheat grain harvest) to early October was detected as stored water in the monocropped wheat plots. More grain production and more effective use of annual precipitation and soil water were achieved 3 out of 4 years when wheat and grain sorghum were double-cropped
