Scientists in China have made a revolutionary discovery in the field of agriculture. Researchers from the Yunnan Academy of Agricultural Sciences have developed a new type of rice cultivar. It has been named “Perennial Rice – PR23”. Normally, rice can be harvested in a single season if planted once. But this new type of rice can provide a continuous crop for up to six consecutive seasons (about three years) if planted once. The plants have the ability to renew themselves and produce crops again, without the need to re-seed. This has the potential to bring about a revolutionary change for farmers around the world.

Scientists have been researching this strain for about two decades. This hybrid strain was created by crossing common rice varieties with wild rice species that can withstand drought. Its specialty is that after each harvest, the plants regrow through the rootstock. This eliminates the need for farmers to plow the soil again, reduces the cost of seeds, and also conserves nutrients in the soil. Scientists say that in addition to maintaining crop production, it is also good for the environment. Reports indicate that this will reduce carbon emissions and significantly reduce water consumption.
Currently, this “Perennial Rice PR23” is being experimentally cultivated in 17 countries. These include the Indian states of Tamil Nadu and Odisha. Farmers are expressing enthusiasm after getting good yields in the first two seasons. This is expected to reduce the cost of seeds by up to 60% and labor by up to 50%. Experts believe that this crop will be a big help to farmers in poor and developing countries on an international scale. This innovation of “planting once, harvesting many times” is considered a crucial step for future food security.
