The objective of this research was aimed to investigate the factors effecting Khao Dawk Mali 105 productivity and compare the rice productivity in difference potential areas on agriculture in Tungsamrit, Thanlalord sub-district, Phimai district, Nakhonratchasima province. The quantitative research method utilising structured questionnaire was employed to interview the sample of 239 people in agricultural households. The factors effecting Khao Dawk Mali 105 productivity use was through Analysis of Covariance (ANCOVA), Multiple Classification Analysis (MCA) and the comparative analysis of rice productivity use t-test. The result of research revealed that the size of planting and income were at a significant level of 0.01; selecting seed, saline soil problems and knowledge of increasing rice productivity effecting Khao Dawk Mali 105 were at a significant level of 0.05. The productivity of Khao Dawk Mali 105 in the high potential area and the moderate potential area were not statistically significant at a difference of 0.05 level. However, the effecting factors were; type of owner areas, seed selection, seed preparation and the saline soil problem. Its also shown that there are differences to compare these areas. Recommendations indicated from this study are that of government involment should take part to give farmers the knowledge about rice productivity. Farmers should be encouraged to know how to achieve the high productivity. Furthermore, the farmer should be supported in selecting good seeds to increase productivity, taught how to protect and solve saline soil problems before planting. |
