Wheat (Triticum aestivum L.) Cultivar Selection Affects Double-Crop and Relay-Intercrop Soybean (Glycine max L.) Response on Claypan Soils

Table 5

Wheat cultivar shoot density, test weight, moisture, and soybean yield main effects for cultivar in a relay-intercropping system planted in 38-cm wide rows in 2003, 2004, and 2005. All data except shoot density were averaged over relay-intercropped soybean cultivars (H431 NC, H432 ITC, and DK 38–52).
