Abstract :

Soybean (Glycine max (L.)Merr.) is the main crop of the Madhya Pradesh area during Kharif season. A field experiments were conducted with Soybean during rainy season during two consecutive years at Bairagarh, Bhopal to find out the degree of nodulation in Soybean fields infested by Euphorbia geniculata Orteg. The root and shoot extract was used to see their effect on the degree of root nodulation of Soybean plant. In almost all experiments in which the nodule number was significantly reduced, the nodules were small and grey or at least not a ight pink as were in the control nodules. In the present study root extract was significantly reduced the nodule number in comparison to shoot extract.
