Abstract

This study was conducted to evaluate the biomass yield and nutrient production of green manure crops for stable crop cultivation in the newly reclaimed Saemangeum tidal land. Treatments consisted of rye monoculture (R100), hairy vetch monoculture (H100), and a 50:50 mixed sowing of rye and hairy vetch (R50H50). Plant height increased in the mixed sowing, reaching 175 cm for rye and 94 cm for hairy vetch compared with their monocultures. The highest dry matter yield was obtained in R50H50 (502 kg 10 a^-1), showing a 113~260% increase over R100 and H100. Nutrient concentrations in plant tissues ranged from 0.93~2.34% for N, 0.72~1.03% for P₂O₅, and 1.24~3.84% for K₂O, corresponding to nutrient returns of 4.1–6.0 kg N, 1.6~5.2 kg P₂O₅, and 5.5~12.1 kg K₂O per 10a. These results indicate that mixed sowing of rye and hairy vetch is more effective than monoculture for improving soil organic matter and nutrient supply in the Saemangeum reclaimed land.
