摘要

<em>Haor</em> represents the food basket of Bangladesh and rice is the only crop grown once a year. Harvesting of rice is labor-intensive works and required migrated labor to complete the harvesting works. Mechanical intervention of rice harvesting is urgently needed to increase the productivity. The proper knowledge of economic valuation and operational necessities needs to use of combine harvesters. Research objective was selected to test the technical and economic analysis of Zoomlion rice combine harvester (which is originally developed in China) in Maisherkandi, Mithamain Upazila under Kishoregonj district. The above-mentioned areas are representing <em>haor</em> areas of Bangladesh. Based on the straight-line method, fixed cost items which are machine purchase price, shelter, tax, and insurance were calculated. During the operation of the combine harvester variable cost items such as maintenance and repair, fuel, oil, drivers and guidance were collected. The breakeven point was calculated in terms of the hectares that must be harvested yearly to cover fixed annual costs;and the payback period. Harvesting speed ranged from 1.23 - 3.20 km<span style="white-space:nowrap;"><span style="white-space:nowrap;"><span style="white-space:nowrap;">&#8729;</span></span></span>hr^{<span style="white-space:nowrap;"><span style="white-space:nowrap;"><span style="white-space:nowrap;">&#8722;</span></span></span>1}.
