Effect of Inherent Soil Nutrients on Yield and Quality of Ramie (Boehmeria nivea L.) Fibre

摘要

Ramie (Boehmeria nivea L.) is one of the most valuable sources of natural fibre known to human civilization from ancient times. The yield and fiber quality of ramie are affected by soil nutrients, particularly nitrogen (N), phosphorus (P) and potassium (K). Variation in organic carbon content of soil influences the fibre quality as it acts as a natural buffer. In the present study, we aimed to correlate the influence of inherent soil nutrients on yield and fiber quality of ramie fibre. Six ramie lines (R-1424, R-1415, R-67-34, R-1411, R-1418, R-1427) were grown in North Eastern hilly regions of India, under normal fertilizer dose was studied to evaluate for differences in plant height, stem diameter, filament length, yield and fiber quality of ramie. It was found that available nitrogen and potassium had significant effect on plant growth, yield, and fiber quality, whereas available phosphorous had strong positive correlation with fineness, strength and length of fibre.
