국문 초록 (Abstract)

□□度가 相異한 土壤에서 잎담배를 栽培할 경우 施□反應을 調査하여 單位面積當 最大 受納代金을 確保할수 있는 施□量을 結晶하기 위하여 實施하였다. 選定된 □場의 土壤理化學性은 上級地에서 有效燐酸, 有機物, 無機態室素 含量이 높았으며, 各 級地別로 잎담배의 收量에 있어서 上級地에서는 75kg/10a, 中級地와 下級地에서는 100kg/10a 施□量일 경우 가장 良好하였다. 잎담배 收量, 品質 및 代金으로 나타난 結果로 各 級地別 適正施□量의 世界는 上級地는 50-75kg/10a, 中級地와 下級地는 100kg/10a 以下인 것으로 判明되었다. 土壤 中 □土深, □酸態□素, pH, 有機物, 燐酸의 함량은 無□區의 收量과 正의 相關이 認定되었다.

Field experiments was conducted to investigate the effects of fertilization on the yields and quality of leaf tobacco grown in soils different fertilities. response of increment of fertilization on varying with soil fertility.
Chemical constituents contents in the soil of experimental fields were shown to be more than those in the fields of moderate and poor fertile soils. Yield of tobacco leaf were increased with the amount of fertilizer(10-10-20) of 75kg/10a in the poor fertile soils, respectively.
The leaf quality leaf was known to be excellent at 50∼75kg/10a in the fertile fields and 100kg/10a in the moderate and the poor. The contents of nitrogen compound of leaf tobacco were increased in proportion to the increment of the amount of fertilizer. The difference of their contents were markedly distinguished between the upper and the lower stalk of leaf tobacco. Content of reducing sugar was reduced.
The relationship between initial physico-chemical characteristics of the field soils and tobacco yield of non-fertilized field, soil depth, NO₃-N, Organic matter, available phosphate contents and pH were known to be highly positive correlation.
