(2015-08-21)Aims: To understand the role of gender on Bambara groundnut cultivation with respect to levels of farmers’ involvement in utilization and conservation in Western Kenya. Study Design: A questionnaire was administered to ... -
Farmers’ perceptions on adoption of Bambara nut production as a food security crop in Kakamega county, Kenya
(2015-08-21)This study was conducted between April and December 2011 to examine perception of smallholder farmers in four districts of Kakamega County, Kenya in adoption of Bambara nut production as food security crop. The study was ... -
Sequentially partitioned population attributable fraction as an estimate of impact of tick presence on infection
(2015-08-21)he impact of Rhipicephalus appendiculatus tick presence (exposure) on Theileria parva infection seroprevalence (outcome) on a farm was assessed in a group of cattle using population attributable fractions (PAF). The ... -
Comparison of soil phosphorous extraction by Olsen and double acid methods in acid soils of Western Kenya
(2015-08-21)hosphorous is an essential nutrient in plants required for root establishment. In the soil, it is applied as DAP, TSP or phosphate rocks. In acid soils, aluminium and iron are dominant and tend to “fix” phosphorous, ... -
Response of Leucaena leucocephala (Lam.) De Wit (Leucaena) Provenances to Aluminium in Potted Soil Experiment
(2015-08-21)Aims: To determine the level of acid or aluminium tolerance provenances in Leucaena (Leucaena leucocephala) a favourite agroforestry tree in Kenya. Study Design: The set up was a 2-factor (provenance-aluminium) experiment ... -
Comparative analysis of phenotypic characterization of Kenya and Pacific Islands tarogen germplasm collections Colocasia esculenta L. (Schott)
(2015-08-21)Fifty accessions of taro germplasm collections Colocasia esculenta L. Received: 15 November, 2014 (Schott) were collected from Kenya and Pacific Islands tarogen germplasm collections. Twenty five accessions of Kenyan ... -
Genetic structure and diversity of East African taro [Colocasia esculenta (L.) Schott]
(2015-08-21)Taro [Colocasia esculenta (L) Schott] is mainly produced in Africa by small holder farmers and plays an important role in the livelihood of millions of poor people in less developed countries. The genetic diversity of ... -
Effect of wheat bran supplementation with fresh and composted agricultural wastes on the growth of Kenyan native wood ear mushrooms [Auricularia auricula (L. ex Hook.) Underw.]
(2015-08-21)Nutrient supplements and agricultural wastes used for mushroom cultivation are important in improving establishment and production of mushrooms. Agricultural wastes such as sawdust, grass, sugarcane bagasse, wheat straw ... -
Impact of a Kraft Pulp and Paper Mill Effluent on Phytoplankton and Macroinvertebrates in River Nzoia, Kenya
(2015-08-21)Phytoplankton and macroinvertebrate assemblages were used to assess the impact of a kraft pulp and paper mill effluent in Kenya, on River Nzoia downstream of the discharge point in relation to changes in water quality ... -
An Ethnobotanical Study of Swamp Wetland Vegetation in Uasin Gishu County, Kenya
(2015-08-21)Ethnobotanical knowledge associated with wetland plants in Uasin Gishu County, Kenya, was assessed and docu- mented. Data on the uses of plants, their local names, and parts used were collected through semi-structured ... -
Cell membrane integrity, callose accumulation, and root growth in aluminum-stressed sorghum seedlings
(2015-08-21)Aluminum stress usually reduces plant root growth due to the accumulation of Al in specific zones of the root apex. The objectives of this study were to determine the localization of Al in the root apex of Sorghum bicolor ... -
Phosphorus Sorption and Lime Requirements of Maize Growing Acid Soils of Kenya
(2015-08-21)In Kenya, maize (Zea mays L.) is mainly grown on acid soils in high rainfall areas. These soils are known for low available phosphorus (P), partly due to its sorption by aluminium (Al) and iron oxides. The study ... -
Genetic Diversity in Cultivated Sesame (Sesamum indicum L.) and Related Wild Species in East Africa
(2015-08-21)Genetic diversity of traditional sesame landraces and related wild species in East Africa remains largely unexplored. Knowing what fraction of the available genetic diversity is actually used by the farmers is of central ... -
Development of maize single cross hybrids for tolerance to low phosphorus
(2015-08-21)Low available phosphorus (P) is one of the major hindrances to maize (Zea mays L.) productivity in acid soils. The objectives of this study were to: (1) develop P-efficient maize inbred lines, (2) develop single cross ... -
Immediate and residual effects of lime and phosphorus fertilizer on soil acidity and maize production in western Kenya
(2015-08-21)Soil acidity and phosphorus (P) deficiency are some of the major causes of low maize yields in Kenya. This study determined the immediate and residual effects of lime and P fertilizer on soil pH, exchangeable aluminium ... -
Phylogenetic relationship among Kenyan sorghum germplasms based on aluminium tolerance
