Effectiveness of Chia Seed Plant Powder in Comparison with Malathion in the Control of Bean Weevils
(East African Journal of Agriculture and Biotechnology, 2023) Kamugisha, Francis; Opio, Fina; Osiru, David; Aharinta, Kenneth Faith
The primary objective of the research was to contribute to the control of storage pests in beans through the use of chia seed plant powder—an organic control method. The study adopted both descriptive and correlational research designs for data collection and analysis. It comprised: a survey of the chia seed farmers in Kyabugimbi sub-county, Uganda, for the purpose of assessing their perception concerning control of storage pests in beans through the use of chia seed plant powder; and an experiment for assessing the susceptibility of a variety of beans and pesticide application. The experiment had three bean varieties: NAROBEAN3, NABE16, and KAHURA. The type of pesticide had two treatments and control, that is, chia seed plant powder and malathion, and each had three levels. A control consisted of dishes with bean varieties infested with weevils without any pesticide added. Each set was comprised of control without any treatment. A total of 54 samples were used. These were laid out in a completely randomised Block design (CRBD) and replicated three times. Pesticides were applied at 0%, 50%, and 100% rates of application. Data were collected on the following measurements: Number of infested seeds, number of adult bruchids that emerged, and weight of seeds at the end of the experiment. The ANOVA test results found that the effect of pesticide application on the number of infested seeds, number of weevils that emerged, and weight of bean seeds was significant (P< 0.01), while the variety of beans was not significant. Although malathion had the lowest bean weevil figures and is therefore more effective in controlling bean weevils, it is a synthetic product, and chia seed would be promoted because it is an organic product because of being more friendly to the human body and the environment than malathion, a synthetic pesticide
Socioeconomic Factors Influencing Uptake of Coffee Production Recommended Practices in Kichwamba and Kirugu Sub-Counties Rubirizi District, Uganda
(East African Journal of Agriculture and Biotechnology, 2023) Ahimbisibwe, Jerome Ronalds; Osiru, David; Fina, Opio
The study was on socioeconomic factors influencing the uptake of coffee production recommended practices in the Kichwamba and Kirugu Sub-counties of the Rubirizi district and was conducted in February 2021. Objectives were to identify the coffee production systems and practices used, identify the socioeconomic challenges associated with the uptake of recommended practices for coffee production, and identify the policy interventions to address the challenges associated with the use of recommended coffee practices. Farmers continue to register low coffee yields hence affecting their livelihoods and incomes and achieving maximum coffee production requires that farmers apply recommended practices since the quantity and quality of the crop rely on the practices used. A cross-sectional survey was conducted using simple random sampling and a total of 376 coffee farmers were sampled. Results indicated that Arabica coffee commonly grown has two major systems intercropping and mono-cropping. The coffee-recommended practices used were weeds control (23.7%), shading (21.5%), pruning (15.5%), fertiliser application (14.1%), pest and disease management (12.2%), water drainage management (6.6%), transplanting (4.0%), and seedbed preparation (2.7%). Statistically significant socioeconomic factors affecting the uptake of recommended practices for coffee were age [p=0.014], education level [p=0.002], labour [p=0.005], Farm size [p=0.001], farming experience [p=0.031], gender [p=0.031], land slope [p=0.048], un-accessibility to credit services [p=0.032], and plot ownership [p=0.049]. Policy interventions were farmer capacity building (35.1%), strengthening agricultural extension (23.7%), credit extension to the farmers (15.7%), re-visiting land reform policies (13.6%), and group formation (11.9%). The study concluded that coffee in the study area was grown under two production systems; intercropping and mono-cropping; the major coffee recommended practices used were; seedbed management, transplanting, pruning, shading, fertiliser application, weeds control, pest and disease
