How much can a mulberry sericulture unit earn in a year and what are the costs?

Treat all figures as ranges. The big advantage of mulberry sericulture is frequent income, because you can take several cocoon crops a year, so a well-run unit generates money through the year rather than once. Your income depends on how many batches you rear, the cocoon weight and quality per batch, the renditta and the cocoon market rate at the time. Main costs are establishing and maintaining the mulberry garden (one-time plus upkeep), the rearing house and equipment, disease-free layings each batch, disinfectants, labour and chawki worms if you buy them. The main risk that wipes out a batch is disease, so disinfection and certified layings are non-negotiable. There are subsidies and support under the Silk Board and state schemes. Build a realistic batch-by-batch budget and confirm current cocoon rates and scheme help with your sericulture department.
