Effects of tillage and nitrogen application methods on fiber yield and quality of Fuhong992

The fiber yield and quality of regular cultivation kenaf (Hibiscus cannabinus L.), Fuhong 992, were determined under three tillage methods (no tillage, ridge tillage and sub-soiling tillage), three nitrogen fertilizing methods (T1: 20% N fertilizer as basal fertilizer; T2: 40% N fertilizer as basal fertilizer; T3: 60% N fertilizer as basal fertilizer). The effects of tillage and N fertilization methods on fiber yield and quality using a field experiment were studied to provide a sensible solution for high yield and high efficient cultivation of kenaf. Results showed that, (1) the yield of fiber and seed reached the maximum when 20% N fertilizer was as base fertilizer and 80% was as top dressing deep tillage farming methods. (2) Compared with no tillage, the yield of fiber and seed, fiber strength increased by 17.0%, 14.8% and 18.4%, while line density decreased by 15.9%. (3) Compared with T1, the yield of fiber and seeds, fiber strength of T2 increased by 17.1%, 30.8% and 17.6%, while line density decreased by 17.3%. Therefore, fibers yield of Fuhong 992 could get the highest at deep tillage combined with 20%N fertilizer as basal fertilizer, and the yield of seed could reach the maximum, too.
