The world record yield for paddy rice production is not held by an agricultural research station or by a large-scale farmer from the United States, but by a farmer in the state of Bihar in northern India. Sumant Kumar, who has a farm of just two hectares in Darveshpura village, holds a record yield of 22.4 tons per hectare, from a one-acre plot. This feat was achieved with what is known as the System of Rice Intensification (SRI).
