ABSTRACT The Tourism sector plays a significant role in the development of many economies worldwide. Ideally, the sector has been credited with the creation of millions of jobs to populations globally. Although tourism has experienced continued growth over the years, the nature of employment the sector has generated still remains an issue of discussion. In fact, there has been wide-ranging apprehension that despite this growth, the sector has not availed satisfactory opportunities for the cre...
ABSTRACT The Nile tilapia, Oreochromis niloticus, is a tropical fish species of commercial importance in both aquaculture and in the wild. It plays a great role in human nutrition and food security. Industrial effluents, contaminated with pollutants such as heavy metals are released into water bodies such as streams and rivers, in most countries. River Ruiru is one of the rivers faced with pollution from nearby industries. It is inhabited by various species of fish such as catfish, tilapia a...
ABSTRACT Sweet yellow passion fruit (Passiflora edulis var. flavicarpa) is widely gaining adoption in Kenya, emerging as an important high market value horticultural crop. However, its current yields are low due to poor agronomic practices among other reasons. The objectives of this study were to determine the effect of vine length on growth, yield and nutrient concentration of sweet yellow passion fruits in Embu County and evaluating orchard management practices for sweet yellow passion frui...
ABSTRACT Species of Aristida are a common component of rangelands of Northern Kenya. They provide high value pasture to livestock, especially during their young stage of growth. The ecological data relating to the distribution of Aristida species at a local scale is scanty. The objectives of this research were; to assess the distribution patterns of the three Aristida species occurring at Kifuko ranch during wet and dry seasons, to determine plant species associated with the three species of ...
ABSTRACT Recent studies have indicated that Bischofia javanica Blume (Euphorbiaceae), a tree species that was introduced in Kakamega forest as a restoration species in the early 1960s, is gradually recruiting and dominating its secondary and plantation forest stands. It is not clear whether this is a transitional succession process or a permanent takeover of the forest. The species has been reported to be invasive in other parts of the world such as Bonin forest and Oceanic Islands in West P...
ABSTRACT African Indigenous Vegetables form an integral part of the Kenyan diets, among the most commonly consumed being the African nightshade. These vegetables contain important phenolics that have medicinal values and good health attributes. The abundance of these phenolic substances has strongly been associated with phosphorus use efficiency. In order to investigate the effect of phosphorus stress on African nightshade distribution, a purposive research was done from February 2014 on 70 ...
ABSTRACT Despite the apparent importance of the dairy sub-sector to Kenya’s economy, the sector is plagued with low milk production. The general objective of the study was to assess dairy performance among the small-scale farmers in Meru County. The specific objectives were (i) to characterize small-scale dairy farmers; (ii) to assess the profitability of small-scale dairy enterprises; and (iii) to determine the factors influencing profitability among small-scale dairy farmers in Meru Coun...
ABSTRACT Tomato (Solanum lycopersicum L.) is one of the most popular vegetable crops grown worldwide, owing to its nutritive value, income generation and diversified use. Tomato cultivation in the coastal region of Kenya is limited by root knot nematodes (Meloidogyne spp.) and Fusarium oxysporum. A survey was done in five farming counties of the Coastal region of Kenya. Meloidogyne spp. and F. oxysporum were isolated from diseased tomato plants and identified. Host resistance and interaction...
ABSTRACT Tomato (Solanum lycopersicum L.) is a valuable vegetable crop in Kenya, grown mainly by small-scale farmers.It provides food security, nutrition and income for many small-holder farmers. Despite its economic importance, tomato production faces major challenges including scarcity of high quality fruits, insect pests and diseases. Currently farmers have relied on application of pesticides to manage the tomato pests. Pesticides are expensive to the farmer and have a negative impact to ...
ABSTRACT Drought has become a major contributor to food insecurity in sub-Sahara Africa. Drought-tolerant crops such as cassava and sweet potato can help alleviate this situation. However, lack of affordable healthy planting materials of farmer-preferred varieties is a major constraint to sweet potato and cassava production. Conventional tissue culture technology offers an important solution to this but it is very costly, making plantlets out of reach for resource poor farmers. Hence, it is n...
ABSTRACT There is an urgent need to improve production and marketing conditions of small holder farmers in Kordofan region of Sudan in order to alleviate poverty and enhance food security. This study was conducted to determine the profitability of the sesame value chain as one of the viable options that can address the challenges of small holder fanners. This study characterized the sesame value chain from producers to processors in terms of material and information flows as well as theinter...
ABSTRACT Nairobi City County is faced with acute water scarcity. The daily deficit is currently 170,000 m3 /day which accounts for about 23%. This deficit will escalate as population increases. However, streets are often flooded during heavy rains and water harvesting has been neglected. The County relies mainly on surface water sources from Athi River basin, Tana River basin and over 3000 boreholes. The objectives of this study were to assess volumes of rainwater that can be harvested from ...
ABSTRACT Integration of crop residues, inorganic N and appropriate tillage system is an important strategy for improving soil fertility, enhancing crop yields and reducing food insecurity. Such integration under zero tillage systems could enhance soil structural development and nutrient management hence mitigating against soil impoverishment through nitrogen and carbon losses. Crop residues combined with inorganic N in zero tillage results to a controlled immobilization-mineralization proce...
ABSTRACT The macadamia industry in Kenya has been faced with numerous operational and marketing challenges forcing the government to impose export ban of raw nuts since 2008 to date. The then Ministry of Agriculture appointed a task force in 2011 to specifically look into challenges that have been facing the macadamia industry including import ban of Kenya’s kernel by USA. Export of macadamia nuts from Kenya has also dropped from 2 nd to 5 th position in sales volume in the world from 1990...
ABSTRACT Food insecurity and hunger are global challenges attributed to poor crop harvests, land degradation, low soil moisture and declining soil fertility. Low maize yields and household food insecurity in Kajiado, Kenya could be alleviated by use of sustainable agricultural practices such as conservation agriculture (CA), integrated soil fertility management (ISFM) and increased water use efficiency. This study was carried out in Kajiado during the long rainy season of March-July, 2016 to...
