Farmers can also create their very own nursery for rising this fern, said Mr. Ramuvel. The box should be ploughed, levelled, irrigated, and made to stand within the type of small ponds. Only 15-20 cm of standing water is permitted within the fields. Green azolla at the fee of 20 kg in keeping with hectare, blended with contemporary cow dung must be released into the pond.

Dense Green Mat:

The fern multiplies unexpectedly in about 10-15 days and bureaucracy a dense growth on the surface of the water. It is then harvested the usage of bamboo baskets and launched into the principle field some of the transplanted paddy plants for further multiplication.
