Abstract

                                Legume nodulation is one of the important soil processes liable to be adversely affected by the application of herbicides. In the present study, five pre-emergence herbicides viz., methabenzehiazuron (1.0 and 2.0 kg/ha), fluchloralin (1.5 and 2.5 kg/ha), bentazon (1.0 and 2.0 kg/ha), alachlor (1.5 and 2-5 kg/ha), and chloramben (1.0 and 2.0 kg/ha) were tested under field conditions to know their effect on nodulation and nitrogen fixa- tion of soybean Inoculated with a composite culture of Rhizobium japonicum. None of these herbicides was found to have any significent effect on nodule number and dry weight, and dry weight of the plant top.
