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. 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.

收量에 있어서는 大體로 떨어진 편이다. 그 理由로서 捻美度가 極히 낮고 精粗 및 玄米 1ℓ重이 모두 떨어졌으며 葉重에 있어서는 섭산벼가 가장 높은 反面 層味重은 부국나 다음으로 많은 편이다. 完全玄米 천립중은 방목목흙나와 수천이 가장 무거우며 그 外는 大差 없다. 精玄比率은 부국나와 수천이 높은 편이고 그 外는 거의 같은 편이다. 이들 指數上으로 볼 때 섭산벼에 比하여 전자금나, 28% 농림1호 20% 농림 24호 18% 농림 26호 16%의 順으로 增收를 가져 왔으며 이를 全般的으로 볼 때 섭산벼에 比하여 增收되었고 그 中에서도 농림系統이 우수 하였다. Upland rice varieties used in this experiment was generally decreased in yields, because these varieties were bad in their maturity rate and their unhulled and hulled rice weight of one liter volume were lighter than paddy field rice. Seubsap rice variety was most heavy in straw weight but crushed rice weight was lighter than Bugcokna variety. In one thousand grain weight of hulled rice, Bangmokokna and Sucheon were most heavy and other varieties had few difference. Bugookna variety had upward tendancy of hulled rice percentage, but other varieties except this variety was mostly same. In the view point of yields, Joonzakumna, Nonglim No.1, 24,26 was increased such as 28%, 20%, 18%, 16% more than Seubsap rice variety, respectively. All of these upland rice varieties were generally increased more than Seubsap variety in yields and Nonglim varieties of them had most yields.
