Study on the Salt Tolerance of Rice and Other Crops in Reclaimed Soil Areas. 6. The Comparison of Growth in the Direct Sowing and Transplanting of Rice Culture in the Reclaimed Salty Areas

간척지에서 수도 및 기타작물의 내염성에 관한 연구 6. 염분간척지에서 직파법과 이앙법에 의한 수도생육의 비교

The Nongkwang variety was sown directly in the field by the three methods of dibbling, drill seeding and broad-casting in non-, low- and high-salty areas, and compared with the growth of transplanted rice in each areas. The yield of rough rice was increased remarkably by direct sowing when compared with that produced by transplanting inboth salty areas, but in non-salty area, the former was decreased significantly. There was no significant difference in the yields of rough rice resulting from three seedling methods of direct sowing in each area. The direct sowing method was predominated in number of panicle, weight of panicle, ratio of matured grains, milling recovery percentage, and straw weight in both salty areas, and dicreased in panicle weight and ratio of matured grain in nonsalty area.
