水稻導入品種의 生産力檢定에 關한 硏究 : 第3報 裁植密度에 關한 生産力 檢定 Ⅲ Productivity trial on planting density = Studies on the Productivity Trial Newly Introduced Rice Varieties

국문 초록 (Abstract)

第3表에서 보는 바와 같이 收量(玄米)에 對한 分散分析의 結果는 다음과 같다.
1. 施肥量에 있어서는 有意差가 나타나지 아니하였다
2. 栽植密度間에는 5%의 有意性이 認定되었다.
3. 普通肥보다 1.5倍肥가 玄米收量 指數는 높으나, 1.5倍肥區는 成熟期에 倒伏이 容易하므로 施肥量은 普通肥가 適當하다고 思料된다.
4. 栽植密度는 施肥量과 關係없이 120株가 가장 높은 比率을 나타내고 있음.
5. 施肥량이 많을수록 紋枯病 發生이 많다.
6. 本品種은 普通肥로서 少株密植이나 多株疏植이 가장 適當하다고 생각된다.

다국어 초록 (Multilingual Abstract)

These experiments were conducted to investigate the reaction of nitrogenous fertilizer and the rate of transplanting for newly introduced rice varieties, Calady 40.
The rate of transplanting were 72, 90, 108, 120 and 144 hills per pyong(3.306㎡) and the quantities of nitrogenous fertilizer were 10.5 and 15.5 kgs per acre.
The results are summarized as follows.
1. There was not any significant in the quantity of nitrogenous fertilizer applycation, but at the 5% lavel the rate of transplantings
2. The yield of unpolished rice was higher at more quantity of nitrogenous fertilizer application, but loading and sheath blight were severely
3. In the rate of transplanting, 120 hills per pyong was the best.
From the results, it is can be recognized that Calady40 could be a profitable to be cultured under standards nitrogenous fertilizer level and few seeding dense planting or many seedling estranged planting.
