Nematode response to soil organic amendments in a semi-arid region under soybean (Glycine max), Naivasha, Kenya.
(University of Nairobi, 2016)Agricultural production within the smallholder farming sector of East Africa is constrained by numerous factors including parasitic nematodes. Existing control measures involving applications of chemical nematicides are ... -
Nematodes Attacking the purple Passion Fruit (passiflora Edulls) Plants In Kenya And Studies On The Biology Of Two Common Species, Meloidogyne Javanica And M. Incognita With Special Reference To their Pathogenicity And Chemical Control
(University of Nairobi, 1993)In a survey of plant parasitic nematodes on passion fruit in Kenya 10 genera of nematodes were discovered. Of these, 8 were identified to species level, two of which attempts were made to determine the existence of races. ... -
Network impact analysis of security attacks in mobile ad hoc networks
(University of NairobiSchool of Computing and Informatics, 2012)Mobile ad hoc networks also known as MANETs have been used extensively for the seamless provisioning of information exchange, where the deployment of infrastructure is difficult, if not impossible. Such cases include ... -
