Labor-saving Feasibilities in Transplanting of Paddy Rice I. Variations in Labor Requirements under the Various Planting Densities
수도 이앙노동의 생력화 연구 I. 이앙밀도 차이에 따른 이앙작업의 노동요구도 변동특성
Abstract
Studying of labor-saving feasibilities in transplanting work of paddy seedling, firstly the five transplanting densities were comparatively examined. The labor-savings were reached as 10, 20, 28% of the whole paddy works, and 28, 39, 61% of the transplanting works by reducing the density as 15, 11 and 8 hills per sq. meter, respectively. However the study on the crop yield and labor-productivity variations as affected by transplanting density of paddy rice was interpreted as the marginal feasibility of density reduction for labor-saving would be more or less than 11-12 hills per sq. meter.
