Six years after leaving a scientific career in Singapore, Dr Jolapuram Umamaheswari has reinvented herself as a silk farmer in Andhra Pradesh, turning sericulture into a steady income-generating enterprise grounded in scientific thinking and experimentation.
After returning to India, she found herself without employment but determined to become self-reliant. Rather than pursuing another conventional job, she explored opportunities where her scientific training could be applied in a practical, hands-on way. That search led her to sericulture—an agricultural practice involving the rearing of silkworms on mulberry leaves, harvesting their cocoons, and extracting silk fibres.
For her, silk farming represented more than agriculture. It was, she says, a discipline that sits at the intersection of biology, precision management, and entrepreneurship. Although the transition felt unconventional, she viewed it as a continuation of her scientific journey rather than a departure from it.
However, the early phase of her farm was far from smooth. She faced multiple challenges including disease outbreaks among silkworms, inconsistent yields, and a steep learning curve in managing a living production system that is highly sensitive to environmental conditions. Over time, she began applying systematic improvements in hygiene, feeding routines, and environmental control, which gradually improved survival rates and the quality of cocoons.
Her persistence has now turned the venture into a stable livelihood. Today, her farm produces around 10 silk crops annually, with each batch of silkworms completing a life cycle in roughly 25 to 30 days. The operation generates an estimated income of around $1,000 per month, providing what she describes as a salary-like consistency. She notes that this regularity makes sericulture distinct from many other forms of farming that depend heavily on seasonal cycles.
The broader silk industry is also undergoing transformation. Experts say modern sericulture is rapidly adopting digital tools and biotechnology to improve productivity. Industry professionals highlight that silkworms grow nearly a thousand times within a short span of about 25 days, but their development is extremely dependent on precise environmental conditions such as temperature, humidity, and the quality of mulberry leaves.
In newer systems, these conditions are no longer monitored manually in many farms. Instead, sensor-based technologies and automated systems regulate airflow, heating, and humidity to maintain optimal conditions. Artificial intelligence is also being used to detect early signs of disease in silkworm populations through computer vision, allowing infected larvae to be isolated before entire batches are affected.
India, the world’s second-largest silk producer after China, remains unique for its diversity in silk varieties. It is the only country that produces all four major commercial types of silk—mulberry, tasar, eri, and muga. Muga silk, in particular, is exclusive to regions such as Assam and Meghalaya, making it globally distinctive.
Research in the sector is also advancing through genome editing and scientific breeding techniques aimed at developing disease-resistant silkworm strains, often in collaboration with international partners. At the same time, efforts are underway to utilise by-products of silk production, such as silkworm pupae, which are rich in protein and increasingly used in poultry and fish feed.
Downstream in the production chain, silk reeling units are becoming more mechanised. Machines now extract silk fibres from cocoons and spin them into thread at a much faster rate than traditional methods, with some systems producing up to 60 kilograms of raw silk per day. Operators say automation and solar energy are making the process more efficient and sustainable.
Despite technological progress, concerns remain about the availability of raw cocoons. Some industry participants fear that declining interest among younger farmers and fragmented landholdings could affect long-term supply. However, officials in the sector argue that improved farming techniques and scientific support are increasing yields per acre, offsetting the decline in farmer numbers.
Back in Andhra Pradesh, Umamaheswari is now planning to diversify her farm further. She is constructing a cattle shed that will add dairy income while also providing organic manure for her mulberry cultivation, integrating another layer of sustainability into her expanding agribusiness model.
