A Study on the Effects of N ,$P_2O_5$ and $K_2O$ Application on the Vegetation and Dry Matter Yield in the Mixed Sward of Ladino Clover and Crabgrass (Digitaria sanguinalis ［L.］Scop.)

Ladino Clover와 바랭이 (Digitaria sanguinalis ［ L.］ Scop. ) 혼생초지에 있어서 질소, 인산 및 가리시용이 식생 및 건물수량에 미치는 영향에 관한 연구

An experiment was canied out to investigate how to effect the application of nitrogen, phosphate and potassium on the vegetation and dry matter yield in the mixed sward of Ladino clover and crabgrass(Digitaria sanguinalis [L.] Scop.). The experimental sward was consisted of eight plots of non-application, K, P, PK, N, NK, NP and NPK. These plots were sown with seeds mixture of Ladino clover 5.0kg/ha and crabgrass 17.5kg/ha on 17 April 1976 in the forage experimental field of Kangwon National University, Chunchon, Korea, and were cut three times from 6 July to 4 October 1976.
