(2016-05-23)There is shortage of onions in Uasin Gishu and Nandi counties during dry season from October to March when the demand is high. Rainfall during the period is inadequate for crop development. This study aimed at testing ... -
GENOTYPE BY ENVIRONMENT INTERACTIONS FOR SUCROSE CONTENT IN SUGARCANE (Saccharum spp. hybrid) CLONES GROWN UNDER RAINFED CONDITIONS IN WESTERN KENYA
(University of Eldoret, 2017)Sugarcane (Saccharum spp hybrid) refers to sucrose storing members of the family (poaceae) and is cultivated primarily for the extraction of sucrose (sugar) from the plant stalks. Recent uses of this tropical crop include ... -
EFFECT OF SPATIAL ARRANGEMENT AND VARIETY ON PERFORMANCE OF COMMON BEAN (Phaseolus vulgaris L) IN WESTERN KENYA
(University of Eldoret, 2017)Common bean (Phaseolus vulgaris) is one of the most important food security pulse crops grown in Kenya. Its production is limited by a number of agronomic practices including spatial crop arrangement and crop cultivar. A ... -
SCREENING OF SELECTED WHEAT (Triticum aestivum L) LINES FOR ALUMINIUM TOXICITY TOLERANCE USING PHENOTYPIC AND SSR MARKERS
(2018)This study was conducted to determine the Aluminium tolerance of fifteen genotypes of wheat. Aluminium (Al) toxicity is one of the major limiting factors for wheat production. Al toxicity inhibits root cell division and ... -
INTROGRESSION AND QTL MAPPING OF STEM RUST RESISTANCE GENES USING BI-PARENTAL WHEAT POPULATIONS
(2018)Rust diseases are a global challenge to wheat production, causing yield losses of up to 50% and even 100% in susceptible host cultivars. A virulent stem rust race named Ug99 (TTKSK) was discovered in Uganda in 1999, and ... -
INTROGRESION OF MAIZE STREAK VIRUS TOLERANCE INTO SELECTED PHOSPHORUS EFFICIENT AND ALUMINIUM TOLERANT KENYAN MAIZE LINES
(2018)Maize is one of the most important cereals produced globally. It has a number of uses such as the production of feed, food, as well as industrial products. However, its productivity is limited by both biotic and abiotic ... -
ASSESSMENT OF GENETIC DIVERSITY AND YIELD OF SELECTED SESAME (Sesamum indicum L.) GENOTYPES IN WESTERN KENYA
(2018)Sesame is one of the most important oilseed crops in the tropical and subtropical regions of the world. Despite its importance, sesame yields in Kenya is very low due to lack of improved and high yielding varieties as well ... -
EVALUATION OF CHICKPEA GENOTYPES FOR RESISTANCE TO ASCOCHYTA BLIGHT IN RIFT VALLEY, KENYA
(2018)In Kenya dry highlands where wheat, maize and barley are main crop, chickpeas are considered as off-season crop (October-February) before the next cropping season providing an alternative source of income to farmers. ... -
FUNGAL PATHOGENS AND THEIR INFLUENCE ON PROTEIN CONTENT IN BARLEY GRAINS
(2018)Barley (Hordeum vulgare) is an annual cereal crop and is ranked fourth in terms of production and utilization after maize, rice and wheat. Its main economic usage all over the world is for malt production. Good quality ... -
DIVERSITY OF ELITE KENYAN BREAD WHEAT MUTANT LINES IN STEM RUST (Puccinia graminis f. sp. tritici) RESISTANCE
(2018)Stem rust caused by Puccinia graminis f. sp. tritici is a major constraint to wheat production in Kenya. The re-emergence of a new fungal race Ug99 and its variants have caused devastating losses to wheat production since ... -
EVALUATION OF KENYAN DOLICHOS (Lablab purpureus L.) GENOTYPES FOR RESISTANCE TO LEGUME POD BORERS (Maruca vitrata and Helicoverpa armigera) USING MORPHOLOGICAL AND BIOCHEMICAL MARKERS
(2018)Dolichos (lablab purpureus) is an important highly proteinous human food and animal feeds. It is grown in the tropics and subtropics of the world. Common production constraints of Dolichos lablab are low yields, poor cooking ... -
