Single cropping: Monocropping is the agricultural practice of growing a single crop year after year on the same land, in the absence of rotation through other crops or growing multiple crops on the same land (polyculture). Corn, soybeans, and wheat are three common crops often grown using monocropping techniques.
Double cropping: Double cropping means to raise two consecutive crops on the same land within a single growing season. to raise two crops per year on (an area of land).
Multiple cropping: In agriculture, multiple cropping is the practice of growing two or more crops in the same piece of land in different growing seasons. It is a form of polyculture. It can take the form of double-cropping, in which a second crop is planted after the first has been harvested, or relay cropping, in which the second crop is started amidst the first crop before it has been harvested. A related practice, companion planting, is sometimes used in gardening and intensive cultivation of vegetables and fruits
