Biological nitrogen fixation by promiscuous soybean (Glycine max L. Merril) in the central highlands of Kenya: response to inorganic fertilizer soil amendments.

Mugendi, E; Gitonga, N; Cheruiyot, R; Maingi, J (IDOSI Publications, 2010)

Biological nitrogen fixation (BNF) by promiscuous soybean cultivars offers a potential for minimizing the investment made by resource-limited farmers in central highlands of Kenya. Nitrogen fixation in this grain legume ...
Effect of inoculating selected climbing bean cultivars with different rhizobia strains on nitrogen fixation

Gicharu, G; Gitonga, N; Boga, H; Cheruiyot, R; Maingi, J (International Journal of Microbiology Research, 2013)

Experiments were designed to investigate biological nitrogen fixation in indeterminate (climbing) bean cultivars namely Cargamanto, NG224-4 and G59/1-2. Greenhouse and field studies were carried out to determine ...
Nodulation and nitrogen fixation in promiscuous and non promiscuous soybean (Glycine max (L.) Merrill) varieties in Eastern Kenya

Gitonga, MN; Gatheri, GW; Cheruiyot, R; Gitonga, NM; Maingi, JM (Kenya Society of Microbiology, 2010)

Soil nitrogen deficiency is a major factor limiting soybean production. This problem can be alleviated by the use of nitrogen fertilizers which on the other hand adversely affect the environment, are expensive and ...
