Managing tillage, sowing rate and nitrogen top-dressing level to sustain rice yield in a low-input, direct-sown, rice–vetch cropping system

摘要

Direct sowing of rice into drained soil is a relatively new farming practice, replacing transplanting, being developed for use in External Low Input Sustainable Agriculture in Korea. Field experiments were conducted to investigate the importance of tillage, sowing rate, and top-dressing of fertiliser nitrogen (N) to rice growth and grain yield in a direct-sown, rice–vetch cropping system.
