Abstract

Several microelements (Mo, Cu, Zn, Mn, B) had some degree of influence on nodule dry weight, plant dry weightand nitrogen content of Phaseolus vulgaris cv. Canellini inoculated with Rhizobium tropici CIAT899 under greenhousehydroponic culture conditions. Nodule number was not significantly affected. The absence of boron producedthe highest degree of inhibition. The absence of microelements affected uptake and assimilation of mineral nitrogento a lesser extent than biological nitrogen fixation. A similar effect of microelements was observed on Phaseolus vulgaris(cvs. Canellini and Mutin)/Rhizobium etli ISP23 symbiosis.
