| Abstract | Field studies were conducted on the IRRI manual rice transplanter 'TR2' under three levels of land preparations (low, medium and high); three water depths : 0 - 3 cm, 3 - 6 cm and 6 - 10 cm; and three seedling ages of 14-17, 18-21 and 22-25 days at the IRRI farm. The results were compared in two other types of soils at the farmer's fields with the best combination of mentioned factors obtained at the IRRI. Some studies on comparison of machine performance with hand transplanting, mat thickness, mat soils, alternative nursery preparation method and sedimentation time requirement in over-puddled soils were also undertaken. At the IRRI farm, the machine performed best under medium level of land preparation, 14-17 days seedlings and 0 - 3 cm water depth. In other two soils of comparatively sandy and sticky in nature, the non-productive hills exceeded 5% limit. Mat thickness of 1.5 cm and seedlings prepared using plastic sheet gave equally superior results over other treatments including dapog seedlings. Plastic sheet also improved seedling mat prepared in sandy and sticky soils. In over-puddled conditions at IRRI farm, the field needed minimum of 4 days to settle for proper functioning of the machine. The working capacity of machine was 0.035 ha/hr at 80.5% efficiency. Machine planting is costlier than hand transplanting at the present (1981) wage rates in the Philippines. However, in situations where intensive use of frames is possible as in rice garden, the machine planting is likely to prove economical even in transplanting an area of 4.33 ha annually. |
