The experiment was conducted to investigate the potential for environmentally friendly cultivation of cv. Haryeong, which was bred by the National Institute of Highland Agriculture in 2006, through evaluation of the late blight field resistance at the farmer's practices level. cv. Haryeong showed higher field resistance to late blight as 590.3 in mean Area Under the Disease Progress Curve (AUDPC) during the cultivation period than cv. Superior as 1377.7 in AUDPC. However there was no observed different trend among the experimental treatments. Mean of tuber yield of cvs. Haryeong and Superior were 2,870 kg/10a and 2,301 kg/10a, respectively, and in all experimental treatments Haryeong was 25% higher than those of Superior. Mean of dry matter content of Haryeong and Superior were 18.1% and 16.1%, respectively, and there were no significant differences among the experimental treatments. cv. Haryeong was confirmed as a suitable cultivar for environmentally friendly cultivation in this experiment. In the future, additional research on fertilization and disease management will be required.
