Effects of Rice-Winter Cover Crops Cropping Systems on the Rice Yield and Quality in No-tillage Paddy Field

摘要: The purpose of this study was to find out optimum conditions for no-tillage rice-winter cover crops cropping system. A field research conducted evaluate productivity and quality rice cultivars (Dongjinbyeo Junambybyeo) in systems at Doo-ryangmyeon, Sacheon, Gyeongsangnam-do, Korea from January 2005 October 2006. experimental soil Juggog series (fine silty, mesic family Fluvaquentic Eutrudepts). were experimented under some different high residue farming systems, i.e. no treatment (NTNT), amended with straw (NTRS), rye (NTR), Chinese milkvetch (NTCMV), tillage (TNT), conventional system (Control). miss-planted rate 8.8%in range 10.8% 13.3% 2006 NTR, the other treatments carried ranging 1.2% 5.0%. Tiller numbers Junambyeo, Dongjinbyeo both years highest Control, decreased nearly NTCMV, NTRS, NTNT, TNT that order. lowest grain yield observed due lower tiller per area, spikelet panicle. Also, than control. On hand, 1,000-grain weight control higher Ripened ratio a similar aspect all treatments. palatability score milled while protein content NTCMV considered an effective sustainable practice quality.
