Item Effect of stinging nettle, African Spider plant and chilli extracts on two spotted spider mite (tetranychus urticae koch) population and damage on roses(Egerton University, 2015-05) Kapsoot, Esther ChebetTetranychus urricae Koch. is a major pest of cut rose flowers and causes high losses if not controlled effectively on time. Laboratory trials were conducted to evaluate and validate the repellent and toxic properties of three local plants Cleome gynandra (capparaceae), Urtica dioica (urticaceae) and Capsicum fiwrescence (solanaceae) against the two spotted spider mite T erranychus urticae Koch (Acari; T erranychidae) on rose flowers grown under greenhouse. 100g of each plant extracts was constituted in methanol and distilled water separately and rose leaves at 3 leaflet stage were immersed in it. Ten TI urticae mites were introduced onto the treated leaves and observations on repellence and mortality of mites was recorded. The experiment was laid out in a Completely Randomized Design with nine treatments replicated three times. Methanol was found to be the most effective solvent and Cleome gynandra, Urtica dioica and Capsicum frutercence methanoic extracts identified and recommended for further evaluation in the field trials for repellence and eflicacy efiects on the yield and quality of out rose flowers. Results showed that these extracts from methanol were effective against T. urticae with the number of mites repelled significantly higher at P5005. Cleome gynandra methanol extract, Capsicum frutescence methanol extract and Urtica dioica methanol extract were the most effective repellents in descending order. Significance of the treatments was more evident with exposure time. The crude extracts on the first day had moderate repellance in the second hour and higher repellence was found on the third and fourth hours after exposure. However, the observations also showed that plant extracts have a slow mortality effect on the two spotted spider mites over the six days period compared to Polytrin miticide which attained approximately 70% kill on the first day to sixth day. The powders were slow acting achieving up to 80% kill on the 6th day as observed in Cleome gynandra methanol extract. The three test plants have repellence and mortality effects which may be used as there is considerable acaricidal activity of C. gynandra, C. frutescence and U. dioica on T. urticae. Their use against the two spotted spider mites significantly reduced the population of mites on rose leaves within a period of six days. However, the level of mortality and repellence was dependent upon the period of exposure to the crude plant extracts. The potential benefits of methanoic plant volatile extraction in the control of mites in rose grown for export markets is evidentItem Farmers participation and perfomance analysis on grain warehouse receipts system in Nakuru District, Kenya(Egerton University, 2014-01) Mutai, Julius KiplangatAlthough maize performs well compared with other grains and legumes in Eastern and South there are challenges in production, post harvest handling and marketing of the maize produce. Majority of farmers sell the maize produce soon after harvest realizing low prices. As £1 effort to mitigate the challenge, the Govemment together with other development partners introduced Grain Warehouse Receipt System (GWRS) under Kenya maize development programme (KMDP). However, the success of the system is yet to be achieved hence the need to be re-examined. This study therefore analyzed level of awareness and factors that influence farmers’ participation in Grain Warehouse Receipt System (GWRS). A multistage sampling technique was adopted in the study with two divisions, Njoro and Gilgil purposely selected. Each of the divisions had 89 maize growing households randomly selected. The sample size thus became 178 households. Data on the socio-economic characteristics of respondents, post harvest costs and maize price movements were collected. Marginal rate of retum (MRR) was used to analyze economic benefits of the system and double hurdle model was used to analyze factors that determine farmers’ participation in the system and the extent of participation. The organizations that offered warehousing services were National cereals and produce board (NCPB) and Lesiolo grain handlers. On level of awareness of GWRS, 38.76% of the household heads were not aware of the existence of GWRS, 34.27% were aware but were not participating in Grain Warehouse Receipt System (GWRS) while 26.97% were aware and were participating in GWRS. Of the household heads that were aware, 4.27% perceived it as less important maize marketing strategy, 36.75% perceived it as important while 58.97% perceived it as very important. Gender and distance to warehouse negatively influenced farmers’ participation in the system while land size under maize production, off farm income, group membership positively influenced farmers’ participation in GWRS. Gender and distance to warehouse negatively influenced the extent of participation in GWRS while land size under maize production, group membership positively influenced the extent of participation. After carrying partial budget and marginal analysis, marketing maize under GWRS was the most profitable compared to other post harvest trading options. The study recommends promotion of Grain Warehouse Receipt System, strengthening of farmer owned organizations, women empowerment in agricultural activities promotion of off farm income generating activities and grain driers and collection points made which Famwers access them.Item Amelioration of Drought Stress in Purple Passion Fruit (Passiflora edulis f. edulis Sims.) using Irrigation and Mulch in a Polyfilm Covered Rain Shelter(Egerton University, 2012-01) Gaturuku, Joseph KinyuaItem Bio-Economic Modelling to Support Genetic Improvement of Dairy Cattle in Kenya(Egerton University, 2014-04) Wahinya, P.
