Simulating furrow-dike impacts on runoff and sorghum yields

, : Simulating furrow-dike impacts on runoff and sorghum yields. Transactions of the ASAE American Society of Agricultural Engineers 30(1): 143-147

A 20-year simulation study of furrow dyking was conducted for 3 Texas locations following the validation of the crop model which was modified to account for dyking effects on runoff. It was found that furrow dyking is likely to increase sorghum yields if the practice is applied on an annual and continuing basis. Dyking only in the growing season increased av. annual sorghum yields by approx. 350 kg/ha to 590 kg/ha, while year-round dyking increased yields by 490 kg/ha to more than 1100 kg/ha.
