Tillage Effect On Soil Water Content And Soybean (Glycine Max) Yield In A Strip Intercropping System, M. Ghaffarzadeh, F. Garcia Prechac, M. M. Harbur, R. M. Cruse

Journal of the Iowa Academy of Science: JIAS

Soybean [Glycine max (L.) Merr.] response to strip-intercropping with corn (Zea may L.) and oat (Avena Jativa L.) interseeded with nondormant alfalfa (Medicago Jativa L.) may be affected by soil moisture. A three-crop strip-intercropping system of corn, soybean and oat interseeded with nondormant alfalfa was established to determine the effect of tillage system and row position on soil water content and grain yield in the soybean strip. The experiment was a split-plot design with three tillage treatments (conventional, CT; reduced, RT; and minimum tillage, MT) as main plot effects and three row positions (both edge rows and the center …
