부산물 석고처리가 마늘(Allium sativum L.) 생육에 미치는 영향 : Allium sativum L. = Effect of Phosphogypsum Application on Growth and Yield of Garlic

다국어 초록 (Multilingual Abstract)

The effect of phosphogypsum and lime application on the soil pH, exchangeable Ca, Mg and K concentration in acid soil and their effect on plant growth and yield of garlic(Allium sativum L) were investigated at National Danyang Garlic Agricultural Experiment Station, Danyang, Korea. The Phosphogypsum(PG) and lime were applied to soil at the rate of 100kg/10a the soil pH and exchangeable Ca and Mg concentration in subsoil increased due to the application of phosphogypsum when compared to soils of lime and control treatments howerver, K concentration remained unaffected te application of phosphogypsum improved the plant height, leaf length and weight over control the lime application also increased the plant growth and yield slightly over control. Therefore phosphogypsum application could be recommended for acid soils to improve some of the soil chemical properties in order to improve productivity of garlic.
