Background and Objective: Since the chemical fertilizers were prohibited, the use of compost instead of chemical fertilizer was needed. This research project aims to study the type and rate of compost suitable for organic asparagus production by farmers in Koh Rang Sub-District, Chai Badan District Lopburi Province, Thailand. Materials and Methods: The production of organic asparagus is carried out under the control of the Department of Agriculture, Thailand. Using locally available agricultural materials to produce high-quality compost was investigated to increase production yield, quality of asparagus and improvement of soil properties. This research used a factorial randomized block design with the first factors being 3 types of composts. The second factors consist of no fertilizer added as control, chemical fertilizer and 5 rates of selected composts. Results: The results showed that rice straw compost had the ability to promote the yield of asparagus better than other materials such as peanut straw compost and bagasse compost. Rice straw compost at the rate of 6 tons/rai gave the cumulative number of shoots equivalent to chemical fertilizer application of 30 kg/rai according to the farmers’ methods, which were 17.2±0.6 and 14.0±0.4 shoots/plant, respectively. Conclusion: The use of the rice straw compost resulted in an increasing amount of nutrient accumulation in the soil such as phosphorus and potassium affecting to stimulate asparagus yield.
