Effects of Nitrogen Application Levels and Ryegrasses as a Member of Mixture on Improvement of Oversown Pasture I. Establishment, botanical composition and productivity
겉뿌림초지 개량효과를 높이기 위해 질소시비수준과 보조초종 라이그라스 조합의 필요성 여부를 구명키 위해 4처리 질소시비수준(0, 100, 200, 300kg/ha)과 3처리 혼파조합(A; orchardgrass+ladino clover, B; orchardgrass+ladino clover+perennial ryegrass, C; orchardgrass+ladino clover+perennial grass+Italian ryegrass)으로 본 시험이 수
This experiment was carried out to determine the effect of improvement of oversown pastures, treated with four nitrogen(N) application levels(0, 100, 200, 300 kg/ha) and three species mixtures (A: orchardgrass+ladino clover; B: orchardgrass+ladino clover+
