|Ratoon rice is an ancient practice in China and Japan. |
It can give 60% yield of the first crop
Rice ratoon is considered to be one of the most ancient rice production practices in Asia. Pioneered at about 1,700 years ago (215 -31 AD), it originated in the Guangdong Province of China. Ratoon rice is produced from the second crop growing from the stubble after harvesting the main crop. It can produce about 60% grain yield of the first harvest, and provides several benefits such as reduced labor inputs, increased grain yield and profit, and optimal use of resources. Due to its efficiency, rice ratoon was widely adopted in several provinces in China.
In Hubei Province, ratoon rice production peaked at 300,000 ha in the early 1990s. However, the volume fell to 6,600 ha by the year 2012. The reason for the drop is linked to high labor needs, particularly when the main crop was manually harvested. The high rates of migration of rural workers to cities is also one of the causes. The challenge, therefore, is to integrate mechanization of rice production with the practice of rice ratooning.
