Abstract
Many factors affect nodulation of legumes of which, nitrogen fertilizer and method of inoculation play a vital role. Thus, a study evaluated the effects of the above factors on nodulation and yields of two common tropical food legumes, namely Mungbean and Bushbeans which are considered extensive and poor nodulatingo species respectively. Inoculation increased nodulation of bushbeans and to a lesser extent in mungbeans. This effect was more evident with time. Nodulation was reduced in the presence of nitrogen fertilizer, and the effect was more pronounced in the extensively nodulating species, mungbean. Nitrogen and nodulation increased yields of both species. The results indicate the inability of bushbeans and to a lesser extent mungbean, to meet all nitrogen requirements by nodulation and nitrogen fixation alone. This suggests the need for some fertilizer nitrogen for tropical legumes in addition to inoculation to obtain optimal yields.
