          Study of the rate of force aerated composting and types of animal manure extract liquid fertilizers suitable for organic sesame seed production in Lopburi province produced in farmers' farms that have certified organic production sources. Step one to study the appropriate rate of force aerated composting for organic sesame seed production. By adding force-aerated composting at rates of 500, 1,000, 1,500 and 2,000 kilograms/rai 30 days before planting sesame compare with non forc-aerated composting. It was in the soil, the pH is neutral, high organic matter, low nitrogen, high phosphorus and high potassium found that adding at force aerated composting a rate of 1,500 kilograms/rai the highest yield of organic sesame seeds is 62.0 kilograms/rai organic sesame seeds have a moisture 6.4%, germination 82.3% and purity 99.5% seed quality standards certified seed or extension seed. Step 2: Study the type of manure extract liquid fertilizer suitable for sesame seed production add force aerated composting rate of 1,500 kilograms/rai according to the results of the step one of the experiment and sprayed with water extracted from pig manure, chicken manure, and beef manure every 15 days, 4 times, compared to adding aerated compost at a rate of 1,500 kilograms/rai and do not add compost It was found that adding 1,500 kilograms of force aerated composting kilograms/rai and sprayed with chicken manure extract the highest yield of sesame seeds is 131.2 kilograms/rai organic sesame seeds have a moisture 5.7%, germination 82.0% and purity 99.9% seed quality standards certified seed or extension seed and has a net income of 2,315 baht/rai. The results of the experiment can be used as recommendations for farmers who produce organic sesame seeds in Lopburi province and organic sesame growing areas throughout the country it is recommended to add aerated compost at the rate of 1,500 kilograms/rai 15 days before planting when the sesame plants have sprouted in 15 30 45 and 60 days spray them with chicken manure extract it will help the sesame plants have good growth, high yields, and the organic sesame seeds are of seed quality standards certified seed or extension seed.
