Author G S … While with rice growing and cultivation the flooding is not mandatory, all other methods of irrigation require higher effort in weed and pest control during growth periods and a different approach for fertilizing the soil. Showing the existence of rice cultivation in West Africa for at least two thousand years and proving that a) the variety of rice plant is not the same as the one in Asia and b) that a vast body of knowledge about rice growing existed in West Africa when the Portuguese first arrived there, she lays firm groundwork on which to build her idea that it was African slaves .

In recent times, focus has been on increasing and developing rice cultivation and production in Nigeria by the federal government. Rice cultivation can promote biodiversity, as flooded rice fields can be a habitat for various animals and other plants. It needs well-drained fertile soils. The System of Rice Intensification involves cultivating rice with as much organic manure as possible, starting with young seedlings planted singly at wider spacing in a square pattern; and with intermittent irrigation that keeps the soil moist but not inundated, and frequent inter cultivation with weeder that actively aerates the soil.
