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

Abstract

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 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 kg/rai 15 days before planting sesame compare with non force-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 kg/ rai the highest yield of organic sesame seeds is 62. 0 kg/ 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 kg/ 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 compared to adding aerated compost at a rate of 1,500 kg. / rai and do not add compost It was found that adding 1,500 kg. of force aerated composting kg/rai and spray with liquid fertilizer extract chicken the highest yield of sesame seeds is 131. 2 kg/ rai by spray with liquid fertilizer extract pig 130.6 kg/rai and spray liquid fertilizer extract beef 126.7 kg/rai. Organic sesame seeds have a moisture 5.7- 5.9% germination 85.2-82.0% and purity 99.7-99.9% seed quality standards certified seed or extension seed and benefit cost- ratio (BCR) 1.75.The results of the experiment can be used as recommendations for farmers who produce organic sesame seeds in Lopburi province and sesame growing areas throughout the country it is recommended to add aerated compost at the rate of 1,500 kg/ rai 15 days before planting when the sesame plants have sprouted in 15 30 45 and 60 days with liquid fertilizer extract chicken or spray with liquid fertilizer extract pig or spray liquid fertilizer extract beef 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.
