    (Uva Wellassa University of Sri Lanka, 2016) Rupasinghe, R.A.D.S.; Jayasinghe, H.A.S.L.; Rathnayake, R.M.P.S.; Silva, T.A.P.
    Pineapple is the third largest agricultural product after tea and coconut which has a demand in export market. Although the nature has blessed with an ideal climate for growing wide range of delicious fruits including pineapple, Sri Lanka is not in a position to meet the growing demand. Therefore, that is very important to study about the export performance of fresh pineapple in Sri Lankan context. The general objective of this study was to identify the determinants of contribution of pineapple growers for export volume in Gampaha district. A structured questionnaire based survey was carried out to collect the data from random sample of 130 pineapple growers in Dompe and Diulapitiya DS divisions in Gampaha district. Tobit model was used to find out the relationship between dependent variable and other explanatory variables, and descriptive analysis was used to explain the characteristics of the sample. The result of Tobit model revealed that the contribution of pineapple growers for exports of pineapple was significantly determined by the age of grower, experience of the grower, pineapple cultivated land extent, amount supply for local market, domestic price and export price. The specific objectives of this study were to study the past export performance of fresh pineapple since 1990 to 2012 in Sri Lanka and to develop the forecasting model and the generalized model for fresh pineapple exports in Sri Lanka. There was an upward trend from 1990 to 2004 and trend was declined from 2004 to 2012 with some fluctuations. The reason was that the export of preserved pineapple has shown a significant improvement within last few years. The other specific objective was to develop the forecast model for future forecast and generalized model for current situation analysis for fresh pineapple exports in Sri Lanka. VectorAutoregressive Model was used to develop the forecast model and the generalized model was developed without considering the time factor. The result revealed that the export of fresh pineapple was significantly determined by the average exchange rate and the domestic price.

    Economics of Selected Domestic Food Crops: A Case Study in Badulla District, 2000-2017
    (Uva Wellassa University of Sri Lanka, 2019-02) Sewwandi, I.M.B.; Wijetunga, C. S.; Rathnayake, R.M.P.S.
    Agriculture is the principal form of livelihood for substantial fraction (57.3%) of population in Badulla District (Department of Agriculture, Sri Lanka). In spite of high incidence of poverty in Badulla district, climatic conditions are favorable for cultivating of domestic food crops such as potato, tomato, pole bean, maize and capsicum which are the most leading food crops in the area. Therefore, this study aims at comparing the profitability of leading food crops in the Badulla district and to analyse the resource use efficiency of these crops for the period of 2000-2017. The Cobb- Douglas production function was applied for each crop separately to compare the resource use efficiency. The study results show that 70% of the variance in the dependent variable can be predicted from the independent variables used in the models. Among the inputs, agro chemicals, hired labor and machinery indicate negative relationship with the gross income for these selected crops. The summation of output elasticities are greater than one (1) in pole bean (Maha season 1.3524 and Yala season 1.1295) which means its production function has increasing returns to scale. This implies that increasing expenditure on resources for pole bean cultivation can help farmers to obtain higher income than their expectation. Furthermore, capsicum and tomato in Maha season also have increasing returns to scale. In addition, potato, maize and tomato in Yala season indicate decreasing returns to scale implying inability to obtain the benefits from returns to scale. Moreover, profitability analysis shows that, pole bean in Yala season and tomato in Maha season has the highest increment in the profitability compared with other domestic food crops in Badulla district. Therefore, the study suggests diverting resources from less profitable crops to high profitable crops in order to enhance the resource use efficiency and to improve the living conditions of the farmers in the area.

    Factors Affecting on Adoption of Paddy Transplanter in Mahawali Areas
    (Uva Wellassa University of Sri Lanka, 2016) Athapaththu, A.M.S.B.; Rathnayake, R.M.P.S.; Gunadasa, H.K.S.G.; Sudeera, N.L.
    After the industrial revolution, many agriculture activities were mechanized. However, seed establishment of paddy is still not mechanized in Sri Lanka. This research was designed to find the reasons for low usage and poor awareness among the farmers about the transplanting machineries. Mahaweli system B was selected for the study considering the usage of machineries in paddy cultivation. Judgment sampling and random sampling methods were used to select the 100 respondents from Aselapura, Damminna and Sewanapitiya areas. A pre tested structured questionnaire was used to collect data. Fourteen variables were subjected to the logistic regression. According to the results, five variables were significantly affected and positively related to adoption for the paddy trans¬planter namely; age of the farmer, experience of the farmer, land area, average yield per acre under 5% significant level and paddy variety under 10% significant level. According to the study, there was a higher yield when using paddy trans-planter rather than using sowing method. But the cost of production and time consumption were high comparative to the sowing method which caused to low usage and poor awareness among the farmers and less attraction of younger generation towards the usage of transplanting machineries.

    Factors Affecting on Direct Supply of Pineapples by the Pineapple Growers
    (Uva Wellassa University of Sri Lanka, 2016) Karunarathna, D.G.N.R.; Rathnayake, M.C.W.M.; Rathnayake, R.M.P.S.; Silva, T.A.P.
    Marketing fresh pineapple produce is important amongst pineapple growers because they derive benefits such as income and rural employment. In developing countries like Sri Lanka, most growers are characterized by poor direct supply of pineapples because they lack market information, high cost of inputs, fluctuations of the prices on pineapple marketing. In Gamapaha and Kurunegala districts growers cultivate pineapple more predominantly than those in other districts. Most of the growers sell their fresh pineapple to the pineapple collectors. However, growers get low income from the fresh pineapple marketing. Therefore, the objective of the study was to determine factors affecting direct supply of pineapple by the pineapple growers and specific objective is to study the socio economic and market characteristics of the pineapple growers .The study was conducted in Gampaha district (Dompe, Diwulapitiya Divisional Secretariat (DS) divisions) and Kurunegala district (Kuliyapitiya, Dambadeniya DS divisions). Judgmental sampling technique was used to select two districts and DS divisions within the districts. Respondents were selected from each DS divisions using simple random technique using a list of pineapple growers. Semi structured questionnaires were used to collect data from pineapple growers through face to face interview and through telephone calls. The data was analysed using descriptive statistics and binary logistic regression model. The results showed that age, farm gate price of pineapple, educational level marketing experience and occupation significantly influenced the decision of direct supply of pineapple by the pineapple growers. The study recommends that government should take necessary actions to develop direct pineapple marketing and facilitate the involvement of the younger generation.
