EFFECT OF FERTILITY ON THE CARBOHYDRATE-NITROGEN RELATION IN THE SOYBEAN

consequent lodging has been found to develop as a result not only of shading but also from hyper-nutrition. In the latter case, particularly in the presence of an abundance of nitrates accompanied by suitable moisture relations, there was set up within the oat and wheat plants a low carbohydratenitrogen relation characterized by a preponderance of vegetative growth, soft, pliable stems, and consequent lodging. Conversely, under relatively poor soil conditions there was developed a high carbohydrate-nitrogen relation characterized by a preponderance of reproductive growth, hard, rigid, stiff stems, and non-lodging. Object The purpose of the work presented in this paper was to ascertain if hyper-nutrition, particularly an abundance of nitrates, affects the carbohydrate-nitrogen relation in soybeans, a legume, the same as it has been shown to affect the carbohydrate-nitrogen relation in other plants such as oats, wheat, and tomatoes.
