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.
The System of Rice Intensification (SRI) is a farming methodology that aims to increase the yield of rice while using fewer resources and reducing environmental impacts. The method was developed by a French Jesuit Father Henri de Laulanié in Madagascar [ 1 ] and built upon decades of agricultural experimentation.
Rice production in Myanmar is heavily dependent on human and animal power, both traditional methods of cultivation. The country has four types of soils that ensure optimal rice growing: gleysols, fluvisols, humic planosols and vertisols. [4] Although soil has a large impact on rice yields, there are many constraints that affect production.
Rice was introduced into the southern states of Louisiana and east Texas in the mid-19th century. [12] Meanwhile, soil fertility in the east fell, especially for inland rice. [6] Emancipation in 1863 freed rice workers. East-coast rice farming required hard, skilled work under extremely unhealthy conditions, and without slave labour, profits fell.

Rice-upland systems generate 49% of the nation's rice production. [16] Manual Transplanting of Rice. Planting methods. Planting methods depend on the environmental and socioeconomic conditions of a growing region. Common methods of planting include manual, throwing, mechanical, direct seeding (manual and mechanic), and ratooning rice. Manual ...
A paddy field is a flooded parcel of arable land used for growing rice and other semiaquatic crops. Paddy fields are a typical feature of rice-growing countries of east and southeast Asia , including Malaysia, China, Sri Lanka, Myanmar, Thailand, Korea, Japan, Vietnam, Taiwan, Indonesia, India , and the Philippines.
Direct seeded rice (DSR) [2] [3] is a practice of sowing paddy which involves planting rice seeds directly into the field, instead of the traditional method of growing seedlings in nurseries and then transplanting them into the fields. This method significantly reduces the demand for labor, one of the major costs associated with rice farming.
