Rice from rhizomes


Perennial rice are varieties of long-lived rice that are capable of regrowing season after season without reseeding; they are being developed by plant genetics at several institutions. These are adapted for different climates and cropping systems, their lifespan is so different from other kinds of rice that they are collectively called perennial rice

perennial crops is an excellent way to stabilize and improve the soil, and provide wildlife habitat.Domesticated Asian rice, Oryza sativa is a short-lived plant. Most cultivars die after producing seeds, though some can regrow and produce a second crop under favorable conditions,that seeds can be developed under perennial.

A way to new technology

The Benefits if this rice is Perennial plants regrow quickly after being harvested, re-establishing a protective cover. The fields do not need to be plowed after the initial planting. Improve the sustainability of food production in the hilly uplands and downstream. It reduced the Environmental impacts of this cropping system include loss if biodiversity, carbon dioxide emissions, increased runoff and decreased rainfall. Due to this Deforestation is reduced quickly.

But it has some drawbacks like Improved habitat for pests, Makes crop rotation more difficult, Builds soil organic matter at the expense of plant productivity, Hydrological impacts like Perennial plants may intercept and utilize more of the incoming rainfall, Reduced nutrient delivery to downstream farms. 

WHY PERENNIAL RICE TO BE PRODUCED: Perennial rice could produce critically needed food year after year on the same plot of land without degrading the soil. This is a potent recipe for soil degradation. Its continuously living roots and thick cover of vegetation would prevent such erosion.Rice with deeper roots, as would be predicted with perennial rice, could exploit the moisture and nutrients in a greater soil volume than short-rooted types.

Reduce the need for transplanting, weeding, and other backbreaking labor. Because of migration to cities, many rural parts of Asia actually suffer from severe labor shortages. In India this plantation grows rapidly.
