In order to apply the fertilization manual to the open-field fertigation system, it is necessary to verify the crop productivity. This study was carried out to assess an appropriate nutrient supply ratio for fertigation in open-field green onion (Allium fistulosum L.) cultivation. In this study, we compared the crop nutrient uptake and soil chemical properties according to the type of basal fertilizer (inorganic fertilizer, organic fertilizer, compost) and the ratio of fertigation (A: N60%, K40%; B: N70%, K50%; C: N80%, K80%) through field experiment. All treatment plots were treated with the same amount of fertilizer, and it was applied according to soil test results. When the fertigation ratio was increased during the crop cultivation period, there was little change in soil EC, NO₃-N, Ex. K, and there was no statistically significant difference in crop yield regardless of the types of basal fertilizer and fertigation ratio. However, the nitrogen uptake of green onions tended to decrease with the increase of the fertigation ratio. In soils with a low nutrient content, if the basal fertilization amount is reduced, the nutrient deficiency in the early stage of crop growth may reduce crop productivity. Therefore, it is recommended to fertigation ratio of A (N60%, K40%) for green onion cultivation in the open-field.
