Abstract This study, the benefits of using amend material of Moon Basin clay and wastewater treatment sediment to the growth and yields of Jasmine 105 rice in the saline area, was to investigate the quality of water and the use of amend material of Moon Basin clay and wastewater treatment sediment on the growth and yields of Jasmine 105 rice, the effect of nutrient amounts on the growth and yields of Jasmine 105 rice before and after cultivation, to compare the effect of the different types of soil improving materials on the growth and yields of Jasmine 105 rice. The study site was in a saline area in Tanot subdistrict, Non Sung district, Nakhon Ratchasima province. Water quality was measured the collected of natural water source used for growing rice. Three 1-kilogram soil samples were collected from each plot at the depth of 30 centimeters. All the samples were mixed together and used and the soil sample for the study. The growth of rice was randomly sampled for five clumps per plot and five tillers per one clump. The investigation was done for number of grains per panicle, number of defect grains per panicle, and rice yield per 25 square meters. The study found that the water quality in the controlled plot had the pH level of 6.48, while the water pH in the experimental plots was between 6.49 and 7.05. The conductivity and the salinity of the water in the controlled plot was higher than those of the natural water in the experimental plots, with the conductivity of 746 ms./cm. and 673-687 ms./cm. and the salinity level of 0.537 ppt. and 0.475-0.501 ppt. in the controlled plot and in the experimental plots, respectively. Soils in all experimental plots were sandy loam with good drainage. After soil improvement and rice cultivation, the soil structure changed to more clay loam which was suitable for growing rice. The improved soils had relatively neutral pH level and slightly changed after cultivation. The heights of the stem were similar in all plots and not statistically different at the .05 significance level. The growth and the yields of Jasmine 105 rice were not different at the .05 level among the plots. However, Plot 5, where the soil was supplemented with clay soil and wastewater treatment sediment at the 500 kg. + 500 kg./rai ratio, gave the highest yield of rice compared to other plots, with 10.34 kg of grain per 25 square meters. Plot 5 also gave the highest number of clumps per plot (410 clumps), while one clump contained 15 tillers. This was followed by Plot 2, supplemented with 10 tons of clay soil per ria, that gave the grain weight of 8.07 kg per 25 square meters. Rice in the controlled plot was found to have pale leave edges, which did not occur in all of the experimental plots.
