Comparative Economic Analysis of Clonal Tea Yield Response to Nitrogen Fertiliser Rates within Selected Geographical Areas in Kenya
(International Journal of Tea Science, 2020-09-09) Rosebell A. Owuor; Alphonce J. Odondo; P. Okinda Owuor; David M. Kamau
Tea sector contributes approximately 30% of export earnings in Kenya. Despite the industry continuing to realize positive gross margins, high costs of production coupled with weak trends in export prices threaten its future contributions. Nitrogen fertiliser is mandatory in tea production and its appropriate use promotes tea growth rate and yields. Previous studies using different tea cultivars established that optimal fertiliser rates varied with clones and geographical area of production. However, economics of nitrogenous fertilisers use on same tea cultivar in different tea growing regions in Kenya remains undefined. This study evaluated response of NPKS 25:5:5:5 fertiliser applied at 0, 75, 150, 225 and 300 kg N/ha/year on clone BBK35 to determine the viable economic rate under uniform management in different locations (Karirana, Timbilil, Changoi, Sotik Highlands and Kipkebe) within Kenya. The study used time series tea yield data and corresponding variable costs from field experiments running from 1997 to 2007. The data were subjected to Partial Budget Analysis (PBA) procedures for economic analysis of on-farm experiments. The economic returns varied with rate of nitrogen and region of production. Maximum marginal rate of return (MRR) were achieved at 75 kg N/ha/year at Kipkebe, Changoi and Timbilil, and 150 at Sotik Highlands and Karirana. However best economic returns were recorded at 300 kg N/ha/year in Kipkebe and Sotik Highlands, 225 kg N/ha/year in Changoi, and at 150 kg N/ha/year in Timbilil and Karirana. These results demonstrate that current uniform fertiliser recommendation rate of 100 to 220 kg N/ha/year may not be suitable for all regions. There is need to develop region specific nitrogen fertiliser requirements for tea growing areas in Kenya.
Effects of Strategy Control Measures on Strategy Implementation at the Lake Victoria North Water Services Board, Homabay County,Kenya
(2020-07) Belyndah Shitakwa Ligare; Thomas Okoth Otieno; Dr. Victor Aliata
The Lake Victoria North Water Services Board (LVNWSB) in Homabay initiated a project with the aim of improving and expanding the network and infrastructure for drinking water and its sanitation in the county of Homabay. At that time, about 92% of the population had no access to piped water which was also of poor quality and high cost. Only 8% of the residents benefited from a continuous water supply. The Homabay Project is worth Ksh 300M which was to be completedby 2017 but up to date it has not been completed. The objective of this study was to establish the effect of strategy control measures on strategy implementation at the LVNWSB, in Homa Bay County, Kenya. The stakeholder theory was used in the study that suggests that an organization is a social construction made of interaction of various stakeholders. This study used correlation survey design.The target population for this study was 50 employees of LVNWSB. Census method was used to survey the target population. The respondents were given questionnaires that were administered through drop and pick method.The questionnaires were pre-tested by conducting a pilot survey from 5 respondents taken from the 50 employees using the internal consistency technique by employing Cronbach Coefficient Alpha test for reliability. Validity was determined using Content Validity Index (CVI). The research instrument was designedto collect qualitative and quantitative data. The researcher used multiple regression analysis using SPSS so as to determine the effects of independent variables on dependent variable.The study findings revealed that strategic control systems have a positive significant effect on strategy implementation (β=.389, p=.000). The study concluded that strategic control systems have positive effect on strategy implementation. The study therefore recommends that the government improves the strategic control measures to enhance strategy implementation at LVNWSB.Findings from this study will be valuable to a number of stakeholders in and outside thewater sector: expanding existing knowledge, referencing and finding comparisons in the quest of getting an ideal strategy-ethics composition and policy approach to stakeholder involvement that would improve service delivery.
COMPOSITION-DIFFERENTIATION OPERATOR ON THE BERGMAN SPACE
(Pan-American Journal of Mathematics, 2023) K. O. ALOO1; J. O. BONYO2; I. OKELLO1
We investigate the properties of composition-differentiation operator Dψ on the Bergman space of the unit disk L2 a(D). Specifically, we characterize the properties of the reproducing kernel for the derivatives of the Bergman space functions. Moreover, we determine the adjoint properties of Dψ whenever ψ is self analytic map of the unit disk D.
Structural Characteristics and Conduct of Sweet Potato Market in Rachuonyo Region, Kenya: Perception of Sweet Potato Farmers and Traders
(East African Journal of Business and Economics, 2023-07-31) Dr. Alphonce Juma Odondo, PhD1*
Myriad studies have been conducted on commodity markets in different parts of the world. However, such studies have yielded inconsistent results on various facets of market structure and market conduct, implying that each market may have its distinctive characteristics which impact on its performance. In SubSaharan Africa, the growth of sweet potato industry is hindered by lack of information on sweet potato market structural characteristics. Kenya’s sweet potato industry is facing a similar challenge. This scenario calls for a baseline survey on the sweet potato market structural characteristics and conduct as a basis for subsequent robust studies on the possible nexus between the market structure, conduct and performance of the industry. The study adopted a descriptive survey design based on interpretivism research paradigm. A sample size of 384 farmers, 166 retailers and 55 wholesalers were taken. Pretested questionnaires were used
to gather perception of the respondents on various parameters based on a fivepoint Likert scale. The views were then summarized in terms of means scores. It was established that the sweet potato market was imperfect since there were notable elements of potato differentiation and barriers to entry into the market. Such barriers included competition from other traders and uncertainties in the demand for sweet potato. The situation was exacerbated by lack of suitable storage facilities given the perishable nature of the commodity. High market concentration was noted at the wholesale level, a likely indicator of price collusion and exploitation by the few large sellers that dominated the market. In this regard, there is need to enhance value addition activities that can enable the market players especially the farmers to be more competitive within the supply chain. Efforts should also be made to eliminate the identified market barriers.
Job Promotion and Employee Performance among the Administration Police in Bungoma County, Kenya
(Cross Current International Journal of Economics, Management and Media Studies, 2020) Belyndah Shitakwa Ligare; Dr. Kadian Wanyonyi Wanyama; Dr. Victor Lusala Aliata
According to Kenya Police Service Annual Crime Reports (KPSACR) of 2016, the number of criminal
offences is still on the increase with the 2013, 2014 and 2015 reports evidencing an offence number of 71832, 72,490 and
73,376 respectively. Based on this upward trend, it is still unclear if the trend is related to human resource practices such
as job promotion as applied in the administration police which in turn have an effect on the performance of the
administration police. In the service industry, especially the Kenya National Police Service, little research has been
conducted on job promotion and employee performance especially in Bungoma County. The purpose of this study was to
establish the influence of job promotion on the performance of administration police. The study adopted a descriptive
survey design. The target population was 1,318 administration police officers in Bungoma County rom which a sample
size of 384 respondents was used. Questionnaires were the main instruments used to collect primary data. Stratified
random sampling, simple random sampling and systematic random sampling techniques were used. Data was analyzed
using both descriptive and inferential statistics. Reliability analysis gave an average Cronbach alpha value of 0.8034
which indicated that the instruments were reliable. Results of the study showed that there was a statistically significant
positive relationship between job promotion and employee performance and that job promotion accounted for 71.3% (R2
= 0.713) variations in the employee performance. It was concluded that if job promotion was well executed in the
administration police, the performance of the staff would be enhanced. The following were the recommendations of the
study: organizations should adhere strictly to its promotion policy, ensure promotion process is fair and that employees
are promoted based on merit. The findings of this study is expected to inform administration police management policy
makers, the government and other stakeholders on relevance and implications of on job promotion in the administration
police aimed at improving the performance of staff
