High-yield varieties: Compared to other cereals including wheat, rice is a high yielding crop even under adverse conditions. When the water supply is adequate, and naturally-occurring nitrogen-fixing organisms exist in the paddy fields, no synthetic fertilizers are required to harvest a local variety of rice up to 2 tonnes/hectare (Swaminathan. The major high-yielding crops, in terms of land devoted to their culture and the total amount of produce, are wheat, corn, soybeans, rice, potatoes, and cotton. Each of these crops originated from a low-yielding native plant that was gradually converted into one of the highest-yielding plants in the world. High-Yield Grains.
