Rice (Oryza sativa L) cultivation in Jumla ranges from 2,400 to 3,050 m altitude, which is the highest elevation in the world.

The highest elevation at 3,050 m is Chhumjul of Jumla, a record altitude, where rice is cultivated in Nepal.

Jumli Marshi, a Japonica variety of indigenous rice, has the cold tolerant gene and has probably been cultivated since 1,300 years ago in Jumla on the bank of the Tila River.

The Tila Valley as well as the Sinja Khola Valley are covered with paddy fields growing the 'Kali Marshi' rice variety, a unique red rice that is sought after for its special taste.

As a result, the climate retains strong diurnal temperature variation in winter and the moderation is from subtropical influence as opposed to maritime.
