Influence of soil fertility management on Striga seed bank dynamics and grain yield of sorghum in semi arid areas
(Department of Land Resource Management and Agricultural Technology (LARMAT)Department of Plant Science and Crop Protection, 2010)The parasitic weed Striga poses a serious threat to cereal production in sub-Saharan Africa. Infestation usually results in significant yield losses, quite often over 70%. Many control options have been reported but, ... -
Traditional soil fertility management strategies: Do they conform to recommendations in organic farming? A case study of the smallholder farmers of the Central Rift Valley Province of Kenya
(Department of Land Resource Management and Agricultural Technology, University of Nairobi,Division of Organic Farming, University of Natural Resources and Applied Life Sciences (BOKU), Gregor MendelStra 33, A-1180 Wien, AustriaDepartment of Crop, Horticulture and Soils, Egerton University, P.O. Box 536, Njoro, Kenya, 2008)The low input nature of organic farming (OF) is often likened to the traditional soil fertility management practices (TSFMP) of smallholder farming systems in developing countries. There are however no concrete studies to ... -
Rational use of pesticides in horticulture with special emphasis on Kenya
(Department of Plant Science and Crop Protection, 1988)The selection of the correct pesticides, dosage rates, treatment intervals, precautions, use and use limitations is of paramount importance. In Kenya the Pest Control Products Board ensures that registered pesticides are ... -
Genetic Nature of Resistance in Corn to Yellow Leaf Blight
(Department of Plant Science and Crop Protection, 1974)Different corn (Zea mays L.) inbreds and hybrids with normal cytoplasm (N) and similar inbreds with Texas (Terns) and other male sterile cytoplasms were compared for their reaction to Phyllosticta yellow leaf blight. ... -

Impact of Traditional Farming Practices on Nutrient Balances in Smallholder Farming Systems of Nakuru District, Kenya
(Ministry of Agriculture, Agroforestry and Soil Fertility Division, Nairobi, KenyaDepartment of Land Resource Management and Agricultural Technology (LARMAT), 2006)The smallholder farmers have not been influenced by the “Green Revolution” as they have continued with the practice of non-use of chemical fertilizers, pesticides and genetically modified organisms. These inherent ... -
Helminthosporium maydis on maize
(Department of Plant Science and Crop Protection, 1979)A severe outbreak of leaf blight on maize in Apr. 1978 in the Nyanza Province, Kenya, was caused by H. maydis [Cochliobolus heterostrophus: CMI Map 346], a previously unrecorded disease -
Genetic linkage of the aphid resistance gene, Rac, in cowpea
(Department of Plant Science and Crop Protection, University of Nairobi, KenyaInternational Centre of Insect Physiology and Ecology (ICIPE), Mbita, 1997)Linkage of the aphid resistance gene, Rac, with various polymorphic loci controlling morphological traits and aspartate amino-transferase isozyme (AAT) was studied in cowpea (Vigna unguiculata L. Walp) with the objective ... -

Evaluation of barley germplasm for resistance to Rhynchosporium secalis at seedling stage in Kenya
(University Of NairobiDepartment of Plant Science and Crop Protection, 1991)Barley lines in the Barley National Performance Trial (BNPT) and introductions in the national germplasm program were evaluated for resistance to an isolate of Rhynchosporium secalis at Njoro. Potted plants were artificially ... -

Distribution and importance of Xanthomonas manihotis and X. cassavae in East Africa
(Department of Plant Science and Crop Protection, 1980)The diseases caused by Xanthomonas manihotis and X. cassavae are currently referred to as cassava bacterial blight. Although the symptoms of the diseases do overlap, some distinctive features can be observed, and the ... -
Reactions of cultivars of bean (Phaseolus vulgaris L.) to bean common mosaic virus (BCMV)
(Department of Plant Science and Crop Protection, 1988-04)3 plants of each cultivar were raised in pots filled with sterile soil, 451 bean cultivars were tested in all. Inoculum was prepared from 30-day-old plants of P. vulgaris. Seedlings of test varieties were inoculated when ... -
Disease progress of angular leaf spot caused by isariopsis griseola sacc. and its implications on resistance of some bean (phaseolus vulgaris l.) cultivars
(Department of Plant Science and Crop Protection, 1988)Disease progress of angular leaf spot caused by Isariosis griseola Sacc. was determined in the field on 14 bean cultivars after artificially induced infection. Isolate IG1-77 of the fungus was used to cause the infection, ... -
Characterization of antibiotic meta bolites from actinomycete isolates
(Department of Plant Science and Crop Protection, 2007): Metabolites from three actinomycetes isolates coded CS35, 28P and 14P antagonistic to Pythium spp were produced in shaken liquid media and centrifugation done to obtain cell free culture filtrates. The antibiotic ... -
