Brown, H.M.
The percentage total dry matter in corn grown with soybeans is not significantly changed, but the percentage of dry shelled grain in the total dry matter is significantly reduced. The percentage total dry matter in soybeans grown with corn as compared to the percentage when grown alone depended on the season, and very probably on other factors, such as available nitrogen, phosphorus, etc., and available water. During the season of 1924 the percentage dry matter was higher in soybeans grown alone than when grown with corn, while in two other years no difference was shown. A significant negative effect was apparent in 3 out of the 6 years of the experiment.
