Abstrakt: Rice is the main staple crop, followed by cassava and corn in Cambodia. Annually, million tons of these crops are produced with the particularly need is its grain or root. After harvesting, these crop residues are usually collected for various purposes. Some of them are burned (the easiest option for farmers), which leads to loss nutrients and air and environmental pollution. However, it is limited report on these crop wastes production and utilization, and the crop residues management remain a challenge in Cambodia. Therefore, this study was conducted to assess to what extent that crop residues are available for further processing in Cambodia manufacture. Two hundred eighty eight key informers, were selected purposively to be interviewed through structure-questionnaire interview. The results showed that the crop residues were produced annually approximately 8.6, 0.9, and 2.9 million ton for rice, corn and cassava, respectively. The rice straw was collected for supplementary feed to cattle, vegetable mulch-based and mushroom production. The cassava stem was collected for next year planting and selling to other farmers. In term of quantity, the crop residues collection was just to meet the household's utilizations and the remaining are burned. For better crop waste management and practice, other alternative uses, for instance development of packaging products, construction materials, paper and renewable energy such as biogas and bio-energy using these residues, will change the open-field option and add value chains to the farm owners and rural people.
