Scientists have developed a new variety of plant that can grow eggplants and tomatoes together using grafting technology. This could benefit city dwellers by allowing them to grow more vegetables in less space. The plant, named brimato, was developed by the Indian Council for Agricultural Research and the Indian Vegetable Research Institute. The process involves vaccinating the eggplants at 25 days and the tomatoes at 22 days, then planting them together after 15 days. This could potentially reduce costs and effort for farmers and increase their revenue.
