A joint National Agriculture and Forestry Research Institute (NAFRI, Laos) – University of Queensland (UQ, Australia) research project funded by ACIAR is evaluating combine performance under different conditions. Conditions being monitored include field size, land levelling and plant and soil conditions at the time of harvesting. The main project activities in the first year have been working with farmer groups to develop larger, levelled fields of around 5 hectares in each of the target villages to test combine performance. The dry season crops have just been harvested in four villages in Central Laos. The information will be used to estimate labour productivity and cost/benefit of combine harvesting under different conditions.
In each village a dryer has been installed and its performance compared with sun-drying method. The artificial drying can be particularly crucial for dry season crops when combine harvested rice cannot be dried because rain often comes at the end of the dry season. Millers have been interviewed around their capacity to dry combine harvested paddy rice.

The project has also interviewed combine harvester contractors. The business is new to the Lao lowland areas, and hence there are a limited number of contractors, but the business appears to be going well and the sector is likely to expand. One contractor commented that she cannot manage all the requests received for combine harvesting and she is starting night shifts in order to double the harvesting capacity.
The project hopes to assist with the timely and cost effective introduction of combine harvesters to the area.
