Relationship between Taro Leaf Blight (Phytophthora Colocasiae) Disease Resistance and Agronomic Traits of Kenyan and Pacific - Caribbean Taro (Colocasies Esculenta) Accessions
(2020)— Taro (Colocasia esculenta) is an important food crop whose production is declining gradually leading to widespread genetic erosion. Despite the limited commercial development, it is important in diet of many in the ... -
Response of Maize to Organic and Inorganic Sources of Nutrients in Acid Soils of Kenya
(2015-07-21)aize yield in Kericho County, Kenya is limited by infertile acidic soils. The effect of inorganic sources of nutrients and amendments; triple superphosphate (TSP), calcium ammonium nitrate (CAN) and lime, were compared ... -
Response of Males of Maruca vitrata Fabricius(Lepidoptera: Pyralidae) to Synthetic Lures in Mauritius
(University of Mauritius research journal, 2009)Maruca vitrata Fabricius (Lepidoptera: Pyralidae) is a key pest of bean in Mauritius. Their larvae feed within flowers and pods and are thus well protected from insecticidal sprays. To achieve effective control, ... -
Response of selected sorghum (sorghum bicolor (l.) moench) genotypes to striga hermonthica (del.) benth in western Kenya
(Journal of Plant Breeding and Crop Science, 2021-06-06)Sorghum is an important staple food crop in Kenya, but its yield is low due to many constraints which include diseases, drought, soil fertility, and pests, notably parasitic weed Striga hermonthica. Twenty elite sorghum ... -
Response of Sorghum (Sorghum bicolor (L.) Munch) and Chemical Characteristics of Soil to Organic and Inorganic Fertilizers on Kenyan Lower Midlands Acid Soil
(International Journal of Plant & Soil Science, 2019-05-17)Soil acidity, low level of nitrogen (N), phosphorus (P) and soil organic matter are major constraints to sorghum production in Kenya. We investigated the effect of farmyard manure (FYM) and combined application of inorganic ... -
Screening of Selected Sorghum Genotypes for Resistance to Covered Kernel Smut Disease in Western Kenya
(Canadian Center of Science and Education, 2021-06-15)Sorghum is an important food security crop for arid and semi-arid tropics but its production is hampered by many biotic and abiotic factors including covered kernel smut disease (CKSD) caused by fungus Sporosorium sorghi ... -
Screening Selected Maize Single Crosses for Tolerance to Low P in Acidic Soils of Bumala and Maseno
(2018)Generally, 13% of Kenya’s arable land mass (7.5 million ha) is acidic and prone to poor phophorus (P) availability and soil acidity. This results in crop yield losses due to the direct adverse effects Aluminium toxicity ... -
Seed Potato Growth, Harvest Index and Net Economic Benefit Improvement through Irrigation Water, Nitrogen and Phosphorus Management
(Columbia International Publishing American Journal of Agricultural Science and Technology, 2016)A study was conducted in a Rainshelter (RTrial) at Egerton University to determine the correlation between irrigation water, nitrogen (N) and phosphorus (P) application on seed potato growth, harvest index (HI) and net ... -
