Allellopathic potential of invasive Psidium guajava L., against selected native tree species in Kakamega Tropical Forest, Western Kenya.
Abonyo, Calvince Rashid Kawawa; Obiri, John; Muyekho, Francis; Omayio, Dennis O.; Humphrey, Agevi; Anastasia, Mwaura; Obiet, Lenard; Kimutai, Donald Kipruto; Sifuna, Anthony (IOSR Journal of Pharmacy and Biological Sciences, 2016-05)Studies have previously attributed P. guajava invasiveness to its aggressive regeneration and profuse seeding. This study, however verified that its allellopathic influence on native plant species also plays an important ... -
Molecular Characterization and Mineralizing Potential of Phosphorus Solubilizing Bacteria Colonizing Common Bean (Phaseolus vulgaris L.) Rhizosphere in Western Kenya
Kiprotich, Kelvin; Muoma, John; Omayio, Dennis O.; Ndombi, Tavasi S.; Wekesa, Clabe (International Journal of Microbiology, 2023-03-01)Phosphorus solubilizing bacteria (PSB) are a category of microbes that transform insoluble phosphates in soil into soluble forms that crops can utilize. Phosphorus in natural soils is abundant but poorly soluble. Hence, ... -
