Question

what is the process by which the quality and yield of the fibres can be enhanced ​

Answer 1

for a good quality yield of fibre's for plants the process is called manuring in which we add manure to the soil for better growth of the fibre yielding plant. manure is actually made from organic wastes like faeces, this waste is further converted to manure when these are placed under the ground.

for animals like silkworm, they should be placed for the conditions they need like suitable environment. proper feeding by leaves or any other as per their breeds. for other animals like sheep, yak or any other these have the same conditions to be measured as described above already.
