It can be concluded based on the findings that the application of liquid natri silicat has effected to decrease the growth of height, and angle between leaf and stem of C70 variety, but increase ability of tillerage, ratio of effective branch, index of leaf area, volume of dry matter and number of rice flower/unit of land, number of good seeds/rice flowers, ratio of good seed and weigh of 1,000 seeds.Therefore, it had effected to increase potential and net yield in comparison with un-control experiment. The result of research is also shown that the appliaction of liquid natri silicat had also effected to increase productivity and quality of rice in the period of post- harvest. All formulas with applicationn of liquid natri silicat had better ratio of return rice in comparison with un- control experiment. Based on the cost-benefit, the optimal formula is to apply liquid natri silicat with dosage 50kg/ha at the time of tillerage. It had increased 11 percent of yield of rice in comparison with un- control experiment.
