To clarify the taxonomic position for Astragalus nakaianus and provide correct scientific name for A. mongholicus cultivar in South Korea, we examined external morphological characters and sequence variations from ITS and five cp non-coding DNA regions. Genetic structure was also analyzed for 61 individuals from three populations using nine microsatellite loci. We found no significant difference between the South Korean cultivar and A. mongholicus var. dahuricus when morphology and ITS sequences were considered. Morphologically, A. nakaianus specimens varied somewhat from A. mongholicus var. mongholicus and var. dahuricus in habit, plant height, and lengths of leaf axis and leaflet. Although sequence data from ITS and cp noncoding DNA regions could not distinguished A. nakaianus from A. mongholicus, microsatellite analysis revealed strong structuring between the cultivar and A. nakaianus. Therefore, we conclude that the South Korean A. mongholicus cultivar should be treated as A. mongholicus var. dahuricus and that A. nakaianus should be merged into A. mongholicus as a variety, i.e., A. mongholicus var. nakaianus.

The effects of ethanol extracts from Astragali membranaceus Bunge (AMB) and A. membranaceus Bunge var mongholicus Hisiao (AMBMH) on antioxidant and nitric oxide (NO) production were evaluated. The total polyphenol contents of AMBMH extracts from two, four, and six-year old roots was 45.3, 71.3, and 78.0 mg/g, respectively. These values and those of total flavonoid content were higher than those of AMB extracts. The DPPH radical scavenging activity was the highest in ethanol extracts from four-year old AMBMH roots. The ABTS radical scavenging activity was also higher than those of AMB in ethanol extracts from four- and six-year old AMBMH roots, but not in two-year old roots. The NO production of ethanol extracts from six-year old AMBMH roots was higher than that of two- and four-year old AMBMH roots. However, there is no significant difference in NO production based on the cultivation period of AMB.

This experiment was carried out to investigate the effect of the mulching of hairy vetch and pig manure on the growth, yield and crude protein contents of the mulching of hairy vetch and application of animal slurry were treated and investigated in $2000{\sim}2002$. At the first year of cultivation, there were no differences among the treatments in plant height, but second year the growth of plants increased and continued over long times as the hairy vetch mulched and fertilized. The length and diameter of plant root were increased in the plot of hairy vetch mulching and the application of animal slurry. At first year of cultivation, no clear difference was found for among the treatments on dry weight and dry matter ratio in roots. At second year of cultivation, they were increased at in the plot of mulching and fertilizer treatment. The appearances of weeds in the field on Astragalus membranaces were much lower on the plots of live-mulching of hairy vetch than those on the control. The yield of root was 255kg highest in the plot of mulching and animal slurry application of 2-year-old roots. The root yield of Astragalus membranaces was increased about $8{\sim}10%$ compared to that with control, due to supply of nutrients. During the cultivation times, organic matters and N contents in soil increased by the mulching of hairy vetch and the application of animal slurry. The concentration of K, Ca concentration in soil showed a tendency to increase.
