Hyderabad Researchers Develop Nano Fertiliser for Rosemary
Imagine plants are like kids who need vitamins.
Usually, we give them vitamins in big pills (regular fertilizer) that they put in the soil.
Sometimes, a lot of the vitamin gets lost before the plant can eat it, and they need many big pills.
Scientists in Hyderabad found a way to make these vitamins super tiny, like dust (nano-fertiliser).
They spray these tiny vitamins directly onto the plant's leaves, like giving them a spray vitamin.
This way, the plant can easily absorb them, so it needs much less to grow strong, healthy, and make good quality oil.
This helps farmers save money and also keeps the soil and water cleaner because less fertilizer is used.
They think this could work for other plants that make special oils too.
Researchers in Hyderabad have developed a nano-fertiliser technique for rosemary cultivation.
The technique involves milling conventional fertilisers into nanosized particles and spraying them on leaves.
This method allows plants to absorb nutrients more efficiently, requiring only 20-30% of the usual dose.
Observed benefits include stronger plant growth, higher biomass, and improved rosemary oil quality.
The approach aims to reduce chemical input costs for farmers and minimize environmental impact.
