Responses of ramte to NPK fertilizer, manure and residues from ramie decortication

The effects of some fertilizing materials on the yield of ramie (Boehmeria niveaGaud.) grown on a recently broken fertile soil were studied through eight consecutive cuts. Satisfactory responses to some treatments were obtained only after the fifth cut. In the three last cuts, the increases in the yield of air-dried, crude fibers due to the applications of residues from mechanically descorticated ramie stalks, manure or mineral NPK + residues were not significant, whereas those due to NPK alone and NPK + manure corresponded to 45 and 51%, respectively, and were significant.
