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 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 ... -
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 inoculation with Klebsiella oxytoca ‘10 mkr 7’on striga suicidal germination in Zea mays
(2008)The Striga species are obligate root parasitic plants. Plant growth promoting rhizobacteria could enhance Striga suicidal germination. In screen-house studies we quantified the effect of bacterial inoculation with ... -
Effect of intercropping maize and beans on striga incidence and grain yield
(2001-02-15)Intercrops can smother weeds in cereal crops and improve the overall productivity. Although intercropping with beans has long been practised in the region, a practical bean population and arrangement is required in the ... -
Effect of nitrogen application on the expression of drought-induced root plasticity of upland NERICA rice
(Taylor & Francis, 2019)This study evaluated the effect of three N fertilization levels 60 (low), 120 (medium), and 180 (high) kg N ha−1 and soil moisture content gradients created by a line-source sprinkler on the expression of plasticity in ... -
Effect of Striga hermonthica (Del.) Benth on yield and yield components of maize (Zea mays L.) hybrids in Western Kenya
(Canadian Center of Science and Education, 2016)Striga hermonthica (Striga) weed is widespread in Kenya, where it causes significant cereal crop losses, particularly when susceptible varieties are grown. The use of maize (Zea mays L.) genotypes that support reduced ... -
The effectiveness of local strains of Fusarium oxysporium f. Sp. Strigae to control Striga hermonthica on local maize in western Kenya
(Wiley, 2020)Striga hermonthica weed infestation continues to persist among smallholder poor farmers in Kenya who depend on traditional maize (Zea mays L.) seeds for their livelihood. The purpose of this study was to evaluate the ... -
Effects of water deficit on days to maturity and yield of three NERICA rainfed rice varieties
(2010)Water deficit is a major problem in rice grown under rainfed conditions. It affects plant growth and development and ultimately leads to a considerable yield reduction or crop failure. Although the rice crop is susceptible ... -
Effects of water deficit on physiology and morphology of three varieties of nerica rainfed rice (Oryza sativa L.)
(2010)Water deficit is a major problem in rice grown under rainfed conditions. It affects plant growth and development and ultimately leads to a considerable yield reduction or crop failure. Although the rice crop is susceptible ... -
Evaluation of Different Improved Upland Rice Varieties for Low Soil Nitrogen Adaptability
(2015)Scarcity of nitrogen fertilizer is a major constraint to rice production particularly in developing countries. Low soil fertility prevalent in farmer’s fields has led to low rice yields and the ever escalating fertilizer ... -

(2015)Scarcity of nitrogen fertilizer is a major constraint to rice production particularly in developing countries. Low soil fertility prevalent in farmer's fields has led to low rice yields and the ever escalating fertilizer ... -
Evaluation of Yield Advantage of Maize+ Artemisia And Maize+ Beans Intercrops In a Sub-Humid Ecozone Of Maseno, Western Kenya.
(2012)An experiment on intercropping systems at Maseno, western Kenya sought to evaluate the yield potential of maize indifferent maize+artemisia spacing regimes in comparison to a standard maize+bean system, by identifying the ... -
Farmer perceptions of Imazapyr Resistant (IR) maize on the control of Striga in Western Kenya
(2008)For a long time, farmers in Nyanza and Western provinces in Kenya have had to deal with the Striga problem. To most of them Striga had become a way of life and they had given up hope. Striga affects their mainstay crops, ... -
Farmer Perceptions of Imazapyr-Resistant (IR) Maize Technology on the Control of Striga in Western Kenya
(2008)For a long time, farmers in Nyanza and Western provinces in Kenya have had to deal with the Striga problem. To most of them, Striga had become a way of life and they had given up hope. Striga affects their mainstay crops, ... -
Field characterization of partial resistance to gray leaf spot in elite maize germplasm
(Phytopathology, 2020)Forty-eight inbred lines of maize with varying levels of resistance to gray leaf spot (GLS) were artificially inoculated with Cercospora zeina and evaluated to characterize partial disease resistance in maize under field ... -
Finger millet
(Springer, Berlin, Heidelberg, 2006)Finger millet, Eleusine coracana Gaertn L., is a cereal grown for food in Africa and Southern Asia, mainly India (the states of Uttar Pradesh, Bilhar, Tamil Nadu, Karnataka, and Andhra Pradesh) and Nepal. In Africa, the ... -
Fungitoxic properties of four crude plant extacts on fusarium oxysporum schl. F. sp phaseoli.
(Rural Outreach Program (Kenya), 2009)Fusarium yellows is a disease of common beans (Phaseolus vulgaris, L.) caused by Fusarium oxysporum Schl. F. sp. phaseoli, it has been found to be important in Busia district of Western province, Kenya. The study on ... -
Generation Means Analysis for Estimation of Genetic Parameters for Striga hermonthica Resistance in Maize (Zea mays L.)
(Canadian Center of Science and Education, 2015-08-01)Striga hermonthica is a parasitic weed species that causes considerable yield loss in susceptible maize cultivars in western Kenya. A generation means analysis was conducted to estimate gene effects influencing resista ... -
Genetic association of agronomic traits with partial resistance to gray leaf spot in elite maize germplasm.
(John Wiley & Sons, 2022)Studies on gray leaf spot (GLS) of maize have reported inconsistencies in the relationship between partial disease resistance and agronomic traits. Understanding this variation could facilitate the use of agronomic traits ...
