Opis:
Irrigation is the artificial application of water to the land or soil. It is used to assist in the growing of agricultural crops, maintenance of landscapes, and re-vegetation of disturbed soils in dry areas and during periods of inadequate rainfall. Paddy production is the main agriculture of this area, has good climate, well irrigation and soil structure for paddy production. Both temperature and rainfall are the main climatic factors that affected the paddy cultivation. The main objective of the study is to find out the agricultural activities especially paddy cultivation. The sampling method has been used to collect the primary data through the questionnaire survey from 100 households and secondary data has been gathered form District Secretariat, Irrigation Report, and published research reports. MS Excel was utilized for the study to examine the changes of paddy production and other agriculture due to the irrigation water. As the result, paddy production was very high in the Maha season but it was low in Yala season because of the less rainfall and irrigation process. In addition, the highland crops were cultivated around 396 hectare in this area. Whatever, when compere with vegetable production, this was very low and the vegetable production was very high. Thus, these area people cultivate different kind of crops for their economy but have the less production. Therefore, the improvement of irrigation and other water body help to make much production can be produced more in highland crops cultivation. Proper management and better agricultural practices cause to the high production in future.

Opis:
Climate change has become a major concern to human society because of its potentially deleterious impact worldwide. The degree to which rainfall amounts vary across an area or through time is an important characteristic of the climate of an area. This subject area in meteorology is called "rainfall variability”. Changes in amount, intensity and frequency affect the environment and society. The annual rainfall varies from 864 mm to 3081 mm (146 years data) distribution, which has sight variation throughout the district. The study purposes to examine the relationship between rainfall and paddy production. Samplings from 100 households have been gathered by questionnaire survey as primary data and the secondary data has been collected Meteorological Department, Department of Agriculture and published research reports. 146 years rainfall data and 34 years paddy cultivation data has been utilized to analyse the result. Accurate statistical methods have been used to find the variability that includes correlation and trend analysis of 3, 5 years moving average of standard deviation. As the result, the study finds that through the 3, 5 years moving average had shown high drier seasons of the years. The paddy production was very high in Maha season but this was very low in Yala season because of the rainfall variability. By the correlation between rainfall and paddy production, the significant value is positive in Maha season and this is negative in Yala season. However, both are having the different significance each other. Thus, even the rainfall was highly influenced to the higher production, this is impossible in each time. Therefore, the development of irrigation tanks and channels, rainwater harvesting and proper management would be supported to more production in Yala season.
