Ecosystems involving upland rice are often relatively diverse, including fields that are level, gently rolling, or steep. Such ecosystems also occur at altitudes up to 2,000 m, with average annual rainfall ranging between 1,000 mm to 4,500 mm. Soils used to grow upland rice range from highly fertile to highly weathered, infertile, and acidic soil.
Experiments with upland rice demonstrated that it could grow over large areas of the country but the crop's yield and quality are inferior to lowland rice produced by irrigation methods.

Abiotic factors include the soil type, whether lowland or upland, amount of rain or irrigation water, temperature, day length, and intensity of sunlight. [5] Rice grains can be planted directly into the field where they will grow, or seedlings can be grown in a seedbed and transplanted into the field.
As a plant breeder, he made significant contributions to rice breeding. He provided guidance for the development, isolation, and release of nine Seed Board rice varieties: Milpal 4, HBD-2, Azmil 26 and C-22 for upland rice production, and C-18, C4-63, C4-137, C-168 and C-12 for lowland rice production.
Rice production is based on its environment, resulting in rain-fed lowland rice, winter rice, deep-water rice, upland rice and irrigate rice. [4] Out of the three distinct seasons, the monsoon season is the main rice production season as rice paddies rely on copious amounts of water. [ 4 ]
Rice raised in the well-watered lowland areas is known as lowland or wet rice. In the hilly areas, slopes are cut into terraces for the cultivation of rice. Thus, the rice grown in the hilly areas is known as dry or upland rice. The yield of upland rice per hectare is comparatively less than that of wet rice.
Upland habitats are cold, clear and rocky whose rivers are fast-flowing in mountainous areas; lowland habitats are warm with slow-flowing rivers found in relatively flat lowland areas, with water that is frequently colored by sediment and organic matter. [3] [4] These classifications overlap with the geological definitions of "upland" and ...
The rice plants are planted in nurseries and then transplanted by hand into the prepared fields. The rice is then harvested in late November – "when the rice bends with age". Most of the rice planting and harvesting is done by hand. The rice is then threshed and stored, ready for the mills. [citation needed]
