Abstract
In order to identify the causes of various problems related to forage crop growth, such as winter survival, coldness, rainfall, drought etc., and to provide basic data for the stable production and supply of forage year round, we performed a growth survey after the wintering of winter forage crops grown from mid-Sep. 2014 to late-Feb. 2015. The growth of winter forage crops after wintering in the country was generally bad. As shown in the regional distribution in the country, regions with 80% or higher winter survival rates comprised 66%, regions with 79 to 50% winter survival comprised 24.9% and regions with less than 50% winter survival comprised 9.1%. In conclusion, the average winter survival rate was 79% in the country. Winter survival rate and coverage rate after the wintering of winter forage crops under installed drain channels in paddy fields were good at 83% and 80%, respectively. However, the rates without installed drain channels were bad at 67% and 66%, respectively. It was predicted that the crop production of winter forage crops was reduced by 10-15% in Gangwon, Chungbuk, Chungnam, Gyeongnam and Jeonnam regions, reduced by 30% in Gyeonggi, Gyeongbuk and Jeonbuk regions and reduced overall by approximately 19% nationwide.
