Azad, Rumana; Senanayake, Gamini; Kumara, K.L. Wasantha; Ranawaka, R.A.A.K.; Wijesinghe, K.G.G.; Pushpakumara, D.K.N.G.; Geekiyanage, Sudarshanee Protogynous dichogamy in cinnamon leads to cross pollination. Morphological variation among mother plants, progenies and other plants in more than 50 year old population due to possible cross pollination was determined. Cuttings of two mother plants and four seedlings from each mother plant were grown in a nursery. Age independent morphological characters of leaf shape, leaf base and leaf apex were taken. None of the progenies were 100% similar to mother plants. New phenotypes for leaf shape and leaf base were found in progenies. This work indicates contribution of cross pollination for allele richness leading to morphological variation in cinnamon germplasm. 2016-08-31T00:00:00Z http://ir.lib.ruh.ac.lk/handle/iruor/7936 JOB SATISFACTION OF EXTENSION OFFICERS: A CASE STUDY IN A PRIVATE ORGANIZATION Widisinghe, S.D.; Sandika, A.L. Involvement of private sector for agricultural extension is reported to be improved gradually in Sri Lanka over last three decades. However, the effectiveness of extension depends on the job satisfaction (JS) of the extension officers (EOs). Therefore, a survey was conducted in this study with product development officers (PDOs) of a private extension company to evaluate job satisfaction of the EOs and to make appropriate suggestions to improve the JS. Data were collected using a structured questionnaire. All PDOs (total population) (25) were participated for data collection. Based on the Frederick Herzberg two factors motivation theory, developed satisfaction index was used to measure the level of satisfaction. Collected data were analysed using descriptive statistics and Wil coxon sign rank test. The findings of the study showed that the PDOs are satisfied with working environment, work responsibilities, available teaching material such as leaflets while they are dissatisfied with rewords, fuel and telephone bill allowances, and job security. With regard to overall job satisfaction, majority (76%) were at the indifferent level. It means that they are neither satisfied or dissatisfied level related to their job. 2017-01-31T00:00:00Z http://ir.lib.ruh.ac.lk/handle/iruor/7934 Development of Ready to Bake Plant Based Cake Mixture for Vegetarians and Egg Allergens Aberathne, P.K.G.M.P.; Navaratne, S.B.; Wickramasinghe, I. A ready to bake cake mixture was developed using wheat, Sugar, coconut milk powder, baking powder, corn starch, xanthan gum, vanilla flavour and cream of tartar. Combination of corn starch, baking powder and xan than gum were used as egg substitution. Eight samples were prepared and the best treatment was selected in terms of sensory properties. Proximate and shelf life analysis were carried out for the best treatment. The best treatment was organoleptically compared with vanilla flavoured cake. Results revealed that there was no signifi cant difference between the two products in overall acceptability. Proximate analysis revealed that developed cake mixture having lower amount of protein and fat than the normal cake due to absence of egg and butter. Coconut milk powder was the only fat source which contributes around 16.74% fat into the final product. The shelf life analysis for the final product was carried out for two months by testing the sensory attributes, moisture content, peroxide value and microbial count under two types of packaging materials (Triple laminated and Polypropylene) as well as at two different temperatures 270C (Ambient) and 40C (Refrigerated). The sensory attributes along with microbiological level, moisture content and peroxides value of the sample packed in Polypropylene and kept un der ambient temperature only had a significant deviation at the end of two months shelf life. 2016-08-31T00:00:00Z http://ir.lib.ruh.ac.lk/handle/iruor/7927 IMPACT OF TEMPORAL CHANGES OF RAINFALL ON MAJOR CLIMATIC ZONES OF SRI LANKA Ampitiyawatta, A.D.; Wijeratne, A.W. Historical and predicted rainfall records and spatial interpolation of temporal trends were analyzed to identify its impact on major climatic zones of Sri Lanka. Data from GHCN version 2.0 of monthly precipitation from 1930 - 2000 of 15 gauging stations in Sri Lanka were used in this study. Annual and four temporal seasons: Southwest monsoon (SWM), Northeast monsoon (NEM), First Inter-monsoon (FIM) and Second Inter-monsoon (SIM) were used for the analysis. Regression models and the Mann-Kendall test were employed to build the linear and non linear long term annual and seasonal models. From 2001 to 2100, monthly rainfall values were simulated from GCMs predictions by using LS-SVM. Then the annual and seasonal spatial distributions of trend statistics were mapped by using the inverse distance weighted interpolation method (IDW). The results suggest that the current boundaries of the wet zone of Sri Lanka have to be broadened and current intermediate zone could be expanded further in the next century. A semi-arid region can be developed around Batticaloa and the eastern coastal belt of the country. Current semi-arid regions may remain unchanged. 2016-12-19T00:00:00Z
