Challenges facing chicken production in Katulani district, Kitui County

Abstract: The poultry industry in Kenya is a key contributor to the local economy as well as food security and income with over 90% of households owning a flock of chicken (Kingori et al., 2010). The main objective of this study was to investigate the challenges faced b y rural and peri urban chicken farmers in Katulani District, Kitui County. The study focussed on understanding the challenges affecting chicken farming, factors affecting technology adoption, access to institutional support s...

The effects of market intelligence systems on sales revenue among French bean producers: a case study of Ol-donyo Sabuk, Machakos County, Kenya

Abstract: Businesses operate in a world in which information is more readily and publicly available than ever before. Thanks to the development of the Internet, information on market trends, legislation, customers, suppliers, competitors, distributors, product development and almost every other conceivable topic is available at the click of a mouse. Search engines, online libraries, company websites and other sources provide information in an increasingly plentiful, easy to find, and easy to...

Long-term salinity changes in the Crocodile river catchment upstream of Hartebeespoort dam

Abstract: This research study investigated the changes in the salinity composition and fluctuation of the Crocodile river and its catchment upstream of the Hartbeespoort dam covering the period of 1985 to 2015. By analysing the 35-year long-term data sets of nine monitoring stations in the study area’s catchment, various trends and patterns emerged. Maucha diagrams and various graphs were drawn by utilising the above-mentioned data sets. These Maucha diagrams and graphs indicated the chang...

Dung beetle assemblages on reclaimed coal mines in eMalahleni (South Africa) their environmental associations and tunnelling ability on compacted soils

Abstract: Opencast coal mining operations are a major contributor to habitat destruction through the removal of soil, vegetation and fauna from an area. Habitat loss and fragmentation is known to adversely impact invertebrates because of their small size and limited dispersal range that also applies to local dung beetle assemblages. Dung beetles have the potential to aid in reclamation efforts through their beneficial activities in soil although there is little known about their assemblages ...

Assessment of the effects of land use methods contributing to watershed degradation in Makueni County

Abstract: Land use changes, rapid population growth, poverty, climate change variability and lack of livelihoods diversification aggravate watershed degradation through inappropriate land use methods resulting to water scarcity, land and water pollution, and governance issues. Soil erosion and siltation has led to land denudation, habitat loss and farm lands losing their soil fertility and compromising food security. The main objective of the study was to find out how land use methods influe...

Effects of phosphorus and soil moisture on grain yield, leaf and grain tissue concentration of iron and zinc in three bean (phaseolusvulgarisl.) genotypes

Abstract: v ABSTRACT Common bean ( Phaseolus vulgaris L .) is an important source of protein, minerals and food for the majority of the poor population in sub - Saharan Africa. However, its contribution to grain yield and micronutrient level is constrained by moisture stress and low available soil phosphorus. A study was carried out to determine the effects of bean genotypes, P fertilizer and moisture regimes on bean ( P. vulgaris L. ) grain yield and tissue concentration of Zn and Fe in thr...

Anthropogenic influences on spotted hyaenas in a protected area the Kruger National Park

Abstract: Human population growth generally causes carnivore declines. The rapid expansion of urban landscapes creates both biotic and abiotic changes that are known to negatively impact carnivore populations (Šálek, Drahníková & Tkadlec, 2015). Carnivores are considered particularly sensitive to human population growth and urbanisation due to persecution, large home range requirements and slow population growth (Woodroffe, 2000). This can cause local extinctions or active avoidance of h...

An evaluation of Brachiaria grass cultivars productivity in semi arid Kenya

Abstract: The scarce and low nutritive livestock forage resource base in semi arid Kenya limits livestock production in these regions. The major factor contributing to this situation is inadequate and erratic rainfall patterns accompanied by long dry spells often culminating into drought. To exploit the full potential of the ASALs for livestock production there is need to expand the forage resource base through introduction of climate smart forage species. This study was carried out to evalu...

Assessment of performance indices of frame hivebeekeeping and the traditional technology in Kenyaa case study of Kitui county

Abstract: The study wa s conducted to assess the performance indices of frame hive beekeeping technology. The objectives were to establish the factors influencing the adoption of frame hives within selected beekeeping groups in Kitui County and compare honey production and household incomes among beekeepers using frame and traditional hives . Data were collected through formal inter views by way of a structured questionnaire , in four locations of Kitui County. Systematic random sampling was...

Investigating the applicability of the CEGAP model to predict the development of harmful algal blooms in the Klipvoor Dam

Abstract: Africa is a water scarce country depending primarily on reservoirs and lakes for socio-economic wellbeing. Most of these reservoirs are contaminated with nutrients making them either eutrophic or even hypertrophic. The algae blooms are common amongst these reservoirs. There is however a worrying trend of an increasing number of reservoirs with cyanobacterial blooms. Cyanobacterial blooms produce cyanotoxins which may result in human and animal deaths. Therefore, it is important to ...

Olfactory responses of the leafhopper vector Mgenia fuscovaria (Stål) (Hemiptera : Cicadellidae) to volatiles from aster yellows phytoplasma-infected and uninfected grapevine (Vitis vinif

Abstract: The leafhopper Mgenia fuscovaria Stål (Hemiptera: Cicadellidae) is a vector of aster yellows phytoplasma (AY), 'Candidatus Phytoplasma asteris', in grapevine, Vitis vinifera L. (Vitaceae), in South Africa. In a previous study, M. fuscovaria was preferentially attracted to AY-infected compared to uninfected grapevine branches, although the mode of attraction was not determined. Phytoplasma infection may alter the volatile profiles of plants, rendering them more attractive to the in...

Factors influencing default in servicing agricultural loans: a case study of Agricultural Finance Corporation, Machakos County

Abstract: Farm credit offered by AFC is an important tool in poverty alleviation through creation of working opportunities for beneficiaries. The facility improves the economic and social status through poverty alleviation, employment creation and income generation for low income farmers with limited opportunities. Through this facility, the government mainly targets to improve the livelihood and food sufficiency among the rural populace. However, loan repayment is faced by high levels of de...

Biomass estimation and utilization of Tarchonanthus camphoratus woodland at Ol Morogi Ranch, Naivasha, Kenya

Abstract: Woodlands cover about 80% of the total land area in Kenya, support 60% of the livestock and are important sources of fuelwood especially charcoal for urban areas. The woodlands of Naivasha, Kenya are dominated by a tree/shrub species Tarchonanthus camphoratus L. which is used for charcoal production using traditional earth kilns. A study focussing on woodland characterisation with respect to species composition and stocking and distribution of T camphoratus and its regeneration cha...

Identification of crop-growing seasons of semi-arid Kenya by analyses of the soil moisture patterns

Abstract: Eight stations with over 30 years of rainfall record were selected in the dry region of Kenya, east of 37°E longitude, to study the nature of the crop growing seasons during the short and the long rains (October through June). The rainfall data were reduced to soil moisture based upon area wide assumptions on the soil characteristics. The start, end and duration of the crop growing seasons were determined and tested for normality using a 10 mm soil moisture threshold value at each...
