Abstract: Toll-Free Agricultural Advisory Service of the Department of Agriculture named as “Govi Sahana Sarana” was established in the year 2006 with the 1920 short code and connected to all of Sri Lanka's land and mobile telephone service providers. Farmers and other stakeholders were enabled to directly contact technical officers (Agricultural Instructors) utilizing this short code. All information was entered into the 1920 call center database manually. Monthly statistics that were generated in the 1920 database were then summarized into a tabular format using Microsoft Excel and distributed to top management of the Department of Agriculture. Top management was assumed to make decisions based on analytics of the content of these reports. Farmers all over the island bring their agricultural problems to 1920 Agricultural Advisory Service. Those may be different types of agricultural problems. These farmers’ problems can be identified into several major categories. However, it can be seen that they do not analyze these problems and give solutions to farmers at that moment only. If so analyses, that big data can benefit in the future on a vast scale at the national level. This study for carrying out to explore the possibility of introducing a decision support for 1920 reporting system to generate enhanced analytics and to make it easier to make informed decisions by the top management of DOA, more efficiently and effectively than the reporting method previously. First, a basic preliminary analysis was performed. Preparing it for further analysis, edited dataset was into describe the main features of the data and summarize the results. Results of the frequency analysis had been obtained. Accordingly, the districts with the highest number of problems were found. It was also possible to find out which category received the most problems. It was also found out from which district the problems related to that category were received the most. Quantitative and qualitative approaches were used to achieve the objectives to do this research. The topic covered include measurement scales, data types and analysis methods. Then, a Regression Model was built using SPSS statistics software. It was able to make predictions related to farmers’ problems. It provides probabilistic conspiracies and other basic descriptive statistics of data, such as mean, standard deviation and so on. There is used validation methods to select the best model. That is the Normal Probability Plot and R Square. It is used these validation methods to select the best model. The results of this analysis can be used as a decision support tool for the Department of Agriculture at the national level. That means, results can be made basing on how the Independent variables respond to the dependent variable, which is very helpful on the decisions of the Department of Agriculture.
