Abstract

This study was to investigate the cultivation technique previously conducted cultivation research for the stable production of alfalfa and to present further research. The data used in the study were 270 alfalfa cultivation experimental data from 1983 to 2008, indicating the cultivation region, field type, variety, sowing, cutting frequency, fertilization, and dry matter yield (DMY). The average DMY of alfalfa in the Republic of Korea was 12,536 kg/ha, which differed greatly depending on the cultivated region. Most of the field type was cultivated in upland. In order to increase alfalfa production, it is necessary to use reclaimed and unused land, and research on the soil amendment matter to improve the soil condition is needed. Alfalfa varieties cultivated an amount of 53, but collected data no studies considered fall dormancy, the criteria for selecting alfalfa varieties, so further research is required. The fertilizer did not consider each component at various levels, and research is needed as the demand for fertilizer. In particular, research on potassium is needed considering the increase in alfalfa production. The alfalfa cutting frequency differed in the estimated pasture production period depending on the region, and the DMY tended to increase with increasing cutting frequency. This suggests that the alfalfa DMY can be increased according to the cutting frequency in the Republic of Korea, so research is needed to present the appropriate cutting frequency.

본 연구는 국내 알팔파의 안정적인 생산을 위해 기존에 재배연구에서 수행한 재배기술을 조사하고 추가적으로 연구해야 될 연구를 제시하기 위해서 수행하였다. 연구에 사용한 자료는 1983~2008년까지 총 270점의 알팔파 재배실험 자료로 재배지역, 재배지, 품종, 파종, 수확횟수, 시비 및 건물수량 등을 수집하였다. 국내 알팔파의 건물수량은 12,536 kg/ha 으로 나타났으며 지역에 따른 차이가 큰 것으로 나타났다. 알팔파는 대부분 밭에서 재배가 되고 있었는데, 국내 알팔파 생산량을 높이기 위해서는 간척지 및 유휴지를 이용할 필요가 있으며 이를 개량할 토지개량제 연구가 필요하다. 국내에서 재배한 알팔파는 53개 품종이었으나 기존의 자료에서는 알팔파 품종선발 기준인 Fall dormancy를 고려한 연구는 전무하여 추가적인 연구가 필요하다. 시비는 각 비료의 성분을 다양한 수준으로 고려하지 않았으며 특히 알팔파 생산량의 증가를 고려할 때 K에 대한 연구가 필요하다. 알팔파의 수확은 지역에 따라 목초의 생육가능일수가 달라 수확횟수가 달랐으며, 수확횟수가 증가함에 따라 건물수량이 증가하는 경향을 보였다. 이는 우리나라에서 수확횟수에 따라 알팔파의 생산량을 높일 수 있을 것으로 생각되어 적정수준의 수확횟수를 제시하기 위한 연구가 필요하다.
