    Evaluation of Local Organic Materials as Source of Organic Pesticides for Pest Control in Carrots.
    (Kabale University, 2024) Kanyesigye, Arozious
    A field experiment was carried out at the Faculty of Agriculture and Environmental Science Research farm at Kabale University located on Kikungiri Hill to evaluate the effect of local sources of organic pesticides for pest control in carrots during the 2023-2024 plating season. Five(5) treatments such as tobacco leaf extract, and wood ash extract, were applied at 10ll liters and a mixture of wood ash and tobacco leaf extract cypermethrin was applied at 30mls/15 liters, control were arranged in a randomized complete block design with 3 replicates Results showed a significant increase in p(<0.05) in growth, yield parameters, and effect on weed and pest population reduction under the use of different organic pesticides on pest control in carrots. The highest growth parameters were obtained under the use of a mixture of wood ash and tobacco leaf extract followed by tobacco leaf extract, wood ash extract, cypermethrin, and control respectively while the highest yield parameters were obtained under tobacco leaf extract followed by mixture, wood ash, cypermethrin, and control respectively The dominant weed was oxalis corniculate which dominated in the control treatment followed by cypermethrin, mixture, tobacco leaf extract, and wood ash extracts. Other weeds that were recorded include Tradescantia zebrina, amaranthas spinosus followed by Cyperus notodus, eymus repens, and Biden polilosa. The key pests recorded were black ants followed by Spiders, cutworms, and caterpillars respectively. Application of cypermethrin decreased Spiders by 66%,,36%, and 33% compared to wood ash extract, mixture, and control treatment respectively. The black ants population under control increased by 31%,5%,26%and 26% compared to tobacco leaf extract, a mixture of wood ash and tobacco leaf extract, and cypermethrin respectively. The highest value of carrot fruit weight was obtained under tobacco extracts followed by wood ash, the mixture of wood ash and tobacco leaf extract, cypermethrin, and control respectively leading to an increase in profit margins and benefit-cost ratio in these treatments respectively except under cypermethrin where the variable cost was higher than gross income. Generally the use of organic pesticides provided good results in controlling pests and reducing weed and yield.

    Evaluation of Organic Pesticides for Pest Control in Cabbages (Brassica Oleracea).
    (Kabale University, 2024) Tubenawe, Ignatious
    A field experiment was carried out at the study and research farm Faculty of Agriculture and Environmental Science Kable university between 2023 to 2024 to evaluate the effectiveness of local organic sources of organic pesticides in the control of pests, and weeds, and increasing the yield of cabbages(Brassicae olarecea). Five(5) treatments were used namely wood ash extracts, tobacco leaf extracts, a mixture of wood ash+tobacco leaf extracts, cypermethrin, and control(no pesticide used) were arranged in a randomized complete block design and replicated three(3) times. The results showed significant increases(P<0.05) in the growth and head yield parameters of cabbage crops under the different organic pesticides in pest control in cabbages. The plant height of cabbages under wood ash extracts increased by 51,27, 32, and 80% compared to cypermethrin, tobacco leaf extracts, tobacco+wood ash extracts, and control treatments respectively. The highest values of cabbage's head yield parameters were obtained under wood ash extracts followed by cypermethrin, tobacco leaf extracts, tobacco+wood ash extracts, and control treatment respectively, and control treatment (no pesticide used) with the lowest yield parameters. Tobacco+wood ash extracts had the best yield weight, Leaf biomass, root biomass, and benefit-cost ratio and this could be because of the combined effect of active ingredients (nicotine and calcium carbonate) that reduced the pests, and weeds and hence increased the yields.

    Evaluation of Sustainable Land Management Practices in Kaharo Subcounty Kabale District.
    (Kabale University, 2017) Nasaasira, Blair
    This study was carried out to examine the sustainable land management practices in Kaharo Sub-County, Kabale District. This was guided by the following research objectives:(i) identify the land management practices, (ii) detennine the effects of identified land management practices and (iii) examine the perception of people about the identified land management practices in Kaharo Sub-County Kabale District. Questionnaire and interview guide were the main instruments for data collection in the study area. The population for the study comprised of farmers and sub county officials. The total population of the study was 99 respondents. Simple random sampling and purposive sampling methods were employed. The major findings of the study revealed that mixed farming, terracing, tree planting, mulching, crop rotation, fertilizer application and minimum tillage was the most land management practices identified in the study area. The effects of land management practices identified in the study area were; reducing soil erosion, improving soil fertility, controls crop pest and diseases, reduces soil compaction, reduce leaching of nutrients and increase soil water uptake and the farmers have knowledge about land management practices in the study area knowing that crop rotation maintains soil fertility, land management practices help in reducing land degradation covering the surface with grass or crop residues reduce and respondents noted that terracing helps us to reduce run-off and rate of erosion. The study recommends that Land management practices are currently being used by farmers but have potential to improve crop production. Policy makers should be aware that the level of practice of the SLM was still very poor in the study area, policy should be formulated that will enforce land users (farmers) to adopt and practice the SLM technologies.
