Ecological implications of Rastrineobola argentea (omena) fishery: A rapid assessment of bycatch diversity at Dunga Beach, Lake Victoria, Kenya
(AfricArXiv, 2022-06)Rastrineobola argentea (omena) is the second most important species in the fisheries of Lake Victoria after Nile perch. However, its fisheries have negative impacts on the ecology of the lake especially because of the high ... -
Ecology and Physiology of Plant growth in relation to soil salinity
(2015)This work is intended as a review of soil salinity as one common abiotic stress in ecological systems that adversely affect plant growth. In arid and semi arid areas, saline areas or areas irrigated with saline waters, ... -
Economic analysis of different options in integrated pest and soil fertility management in maize systems of Western Kenya
(Blackwell Publishing Inc, 2010-09-01)The major biotic constraints to the production of maize, the major staple food in Western Kenya, are field pests such as Striga and stem borers, and low soil fertility. To counter these constraints, new cropping systems ... -
Economic analysis of soil fertility restoration options in potato bean of gardening intercropping in south rift, Kenya
(Academic Journals, 2011-09-26)Soil fertility management options to restore soil fertility depletion have been developed and these consist of inorganic and organic fertilizer applications. However, the adoption rates by smallholder farmers for these ... -
Economic Analysis of Use of Non-Conventional Fertilizers in Maize and Bean Production in Vihiga County, Kenya
(science PG, 2021)The majority of smallholder maize farmers in the study area depend on farming whose returns are very low. This, together with low soil fertility and the inability of farmers to purchase chemical fertilizers, has resulted ... -
Economic efficiency and supply response of women as farm managers: Comparative evidence from Western Keny
(Pergamon, 2008-07-01)This paper assessed the relative economic efficiency and output supply and input demand responses of women farmers in western Kenya. The results showed that women are as technically and allocatively efficient as men. ... -

Economic Evaluation of Organic and Inorganic Sources of Nitrogen under Striga Infestation in Western Kenya
(Journal of Experimental Agriculture International, 2020)Due to escalating cost of imported fertilizers, there is renewed interest in the use of local nutrient resources in managing soil fertility in Kenya. The effect of integrated use of urea and Calliandra or maize stover ... -
Economics of Weather Index-based Insurance: Analysis of Smallholder Farmers' Preferences and the Impact of Insurance on Productivity in Kenya
(Goettingen, 2016)Climatic risks are a major challenge for rural communities, especially those whose livelihoods directly depend on agriculture. Weather extremes affect crop productivity not only through the direct relationship between ... -
Ecosystem productivity and CO2 exchange response to the interaction of livestock grazing and rainfall manipulation in a Kenyan savanna
(Elsevier, 2021)Savanna ecosystems in Kenya are experiencing altered rainfall amount and increased grazing pressure. These environmental alterations occur simultaneously and impact on productivity and CO2 exchange of the savanna in unclear ... -
Effect of farmyard manure and inorganic fertilizers on maize production on Alfisols and Ultisols in Kakamega, western Kenya.
(JO Achieng, G Ouma, G Odhiambo, F Muyekho, 2010)Soil acidity is one property associated with decline of most crop productivity. Alfisols and Ultisols are some of the acidic soils predominant in western Kenya. An experiment was conducted in both soils to find out the ... -
