ICRISAT secures industrial design grant for Solar-Powered Water Hyacinth Harvester

Hyderabad / New Delhi, Dec 11 (FN Bureau) The International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) has said it was granted its first industrial design in India for a Solar-Powered Water Hyacinth Harvester developed by a team of scientists. The harvester is simple, affordable, and can be efficiently managed by semi-skilled or unskilled personnel, the Institute said in a release here. The solar-powered equipment, designed and fabricated in-house, is an affordable solution priced at under Rs 200,000, making it ideal for rural farming communities that cannot afford sophisticated machinery costing 10 times as much. It offers substantial benefits, including 50–60 per cent savings in cost, time, and labour, while prioritising using clean energy.

Water hyacinth infestations in rural ponds disrupt ecosystems, harm fisheries, and block canals. Their rapid growth and long-lasting seeds make eradication difficult. Just 8–10 plants can proliferate into over 600,000 plants within 6–8 months. Chemical and biological removal of the weed has proved expensive and effective only in the short term. The only way to control the weed sustainably is through periodic harvesting, either manually or mechanically. ICRISAT Director General-Interim Dr Stanford Blade on Tuesday commended the team behind the mechanical harvester, stating, “Water hyacinth infestation is a global environmental challenge. This cost-effective harvester reflects ICRISAT’s dedication to creating environment-friendly solutions tailored to the needs of rural communities that are also technologically and economically sustainable.”

ICRISAT’s harvester, categorised as agricultural machinery, was developed as part of the project “Sustainable Valorisation of Water Hyacinth Biomass through Aerobic Composting as a Rural Enterprise—A Waste to Wealth Initiative,” supported by the Department of Agriculture and Farmers’ Empowerment, Government of Odisha. “Experiments conducted by ICRISAT demonstrate that 72,000 kg of water hyacinth biomass can be mechanically harvested from a 3-acre (1.2-hectare) pond in just 2–3 days by a team of two or three people. In contrast, manual harvesting requires 10–20 labourers and takes 18–20 days to complete,” said Dr ML Jat, Research Program Director of Resilient Farm and Food Systems, ICRISAT. The ICRISAT Intellectual Property (IP) office facilitated the evaluation and filing of the application with the Design Registry, India, ensuring due diligence throughout the process.
