Abstract

Strip-intercropping soybean (Medicago sativa L.) with corn (Zea mays L.) decreases yields in soybean border rows. Separating corn and soybean with a small grain strip could decrease competition for soybean and improve overall yield. This study was conducted to determine the effect of a small grain strip on corn and soybean performance and on soil water content in the corn strip. Corn and soybean were strip-intercropped (rows running north-south) with oat (Avena sativa L.) in 1991 and barley (Hordeum vulgare L. emend. Lam.) in 1992 on a ridge-tilled Dalhousie silt loam (fine, mixed, mesic Typic Endoaquoll) in Nepean, Ontario. Both years, plant height varied among corn rows [...]
