Symbiotic nitrogen fixation by broad bean and growth of rhizobium leguminosarum strains as influenced by certain herbicides.

Abstract: The effect of linuron , DNBP Nitralin, Terbutol and chlorothal Dimethyl was studied on nodule formation and symbiotic nitrogen fixation by broad bean. Only the highest rate of Linuron and Nitralin showed an adverse effect on the growth. nodulation and nitrogen content of plants. The lower rates of these herbicides and all rates of the other herbicides tested had no harmful effect; they even caused some stimulation, especially in the dry weights of roots, nodules and nitrogen content. The growth of 14 strains of Rhizobium leguminosarum in vitro was inhibited only by concentrations higher than 10 000 ppm active ingredient of Nitralin, Terbutol and chlorothal dimethyl. DNBP and Linuron caused inhibition at 500 and 1000 ppm, respectively.
