O.; Muchiri, J. M.; Omukoko, C. A.; Gikunda, R. M.; Mbaka, F. K.The development and dissemination of agricultural advisory services (AAS) amongst smallholder sorghum farmers (SHFs) has played a crucial role in sorghum yield improvement in Kenya. However, there is limited information on the influence of AAS on adoption of sorghum production practices amongst SHFs in Tharaka Nithi County particularly Tharaka South Sub-County. The purpose of the study was to generate information that would deepen the understanding of the influence of AAS in enhancing the adoption of sorghum production practices in Tharaka South Sub- County. A descriptive research design was used to describe the characteristics of the study sample. The study targeted 16,437 smallholder sorghum farmers with a sample size of 108 participants. Stratified proportionate random sampling technique was utilized to select farmers from three strata; Marimanti, Nkondi, and Chiakariga wards. A questionnaire was used for data collection. Piloting study was carried out in South Imenti Ward, Meru County which helped to check and advance the validity of research instrument. The reliability of the research instrument was estimated by computing Cronbach’s alpha coefficients of the variables. The Cronbach’s alpha values for the study were: adoption of sorghum production practices (α = 0.771), while that of AAS was 0.710. The SPSS (V.22) was utilized for computing both the inferential (independent samples t-test) and descriptive (percentage, median, frequency, mean and standard deviation) statistics. The study findings indicated that there was no significant difference in the access and adoption of sorghum production practices between farmers with access to AAS from those who did not t (106) = 0.843, p = 0.401, d = 0.1684 and t (106) = 0.203, p = 0.839, d = 0.041, at 95% confidence interval, respectively. It was concluded that AAS had no influence on the adoption of sorghum production practices amongst SHFs in Tharaka Sub-County. Therefore, the study recommends the government through the State and County departments of agriculture should support impactful agricultural advisory programs that target sorghum farmers to increase the productivity of the crop.Item Cardiocurative Effects of Aqueous Leaf Extracts of Ximenia Americana (Linn.) and Pappea Capensis (Eckl. and Zeyh.) Against Myocardial Infarction in Rats(www.bsmiab.org, 2022) Gaichu, D.; Mathabe, P.; Ngugi, M.Different plants are traditionally applied in the treatment of different diseases, including chest pains, hypertension, and inflammation, among others. This study scientifically evaluated the curative treatment effects of X. americana and P. capensis leaf aqueous extracts in rats induced with myocardial infarction. The rats were randomly distributed as follows: Normal control group, consisting of rats treated with oral normal saline; Negative control group, comprising rats induced with MI and treated with normal saline; Positive control group, consisting of rats induced with MI and orally treated with propranolol (10 mg/Kg bw); and three experimental groups consisting of rats induced with MI and treated with plant extracts at dose levels 150, 200 and 250 mg/Kg bw. This study’s findings demonstrated that there was a significant reduction in the amounts of cTnT, LDH-1, CK-MB, T-cholesterol, triglyceride, LDL-c, and malondialdehyde, as well as a significant increase in levels of HDL-c, catalase, SOD, and glutathione peroxidase among rats treated with propranolol and plant extracts as compared to the negative control rats. Additionally, LC-MS analysis revealed the presence of flavonoids, tannins, and phenolics, which could explain the observed cardiocurative effects. This study concluded that aqueous leaf extracts of X. americana and P. capensis possess cardiocurative activities in rats with myocardial infarction. However, further studies on isolated fractions of the phytochemicals present are recommended. This study provides preliminary data useful in the development of pure and safe cardioactive compounds.Item AGED 415: AGRICULTURAL INFORMATION MANAGEMENT(chuka University, 2024-12-12) Chuka UniversityItem AGED 331: RURAL SOCIOLOGY(chuka University, 2024-12-12) Chuka UniversityItem AGED 331: RURAL SOCIOLOGY(chuka University, 2024-12-12) Chuka UniversityItem AGED 323: CURRICULUM DEVELOPMENT IN AGRICULTURAL EDUCATION(chuka University, 2024-12-12) Chuka UniversityItem AGED 314: TECHNICAL WRITING AND REPORTING(chuka University, 2024-12-12) Chuka UniversityItem AGED 0231: RURAL SOCIOLOGY(Chuka University, 2024-12-10) Chuka UniversityItem AGED 221: PRINCIPLES OF TEACHING AND LEARNING AGRICULTURE(chuka University, 2024-12-10) Chuka UniversityItem AGED 111: FUNDAMENTALS OF AGRICULTURAL EDUCATION AND EXTENSION(chuka University, 2024-12-10) Chuka UniversityItem AGEC 854: MATHEMATICS FOR ECONOMIST(chuka University, 2024-12-10) Chuka UniversityItem AGEC 801: MICROECONOMICS(chuka University, 2024-12-10) Chuka UniversityItem AGEC 451: AGRICULTURAL POLICY(Chuka University, 2024-12-12) Chuka UniversityItem AGEC 423: ECONOMICS DEVELOPMENT(2024-12-10) Chuka UniversityItem AGEC 422: AGRICULTURE PROJECT MANAGEMENT AND ANALYSIS(chuka University, 2024-12-10) Chuka UniversityItem AGEC 416: AGRICULTURAL ECONOMICS II(chuka University, 2024-12-11) Chuka UniversityItem AGEC 343: FARM MANAGEMENT PRINCIPLES(chuka University, 2024-12-13) Chuka University
