Farmyard Manure (FYM) is an important organic fertilizer widely used in moriculture, the
cultivation of mulberry plants for silkworm rearing. It is prepared from decomposed cattle
dung, urine, bedding materials, and other farm wastes. FYM plays a significant role in
improving soil fertility and maintaining sustainable mulberry production. The application of
FYM increases the organic matter content of the soil, thereby improving soil structure,
aeration, and water-holding capacity.
