Multiple cropping is widely practiced in vegetable production, where it is possible to grow a cool-season crop (such as lettuce) in the spring, follow with a warm-season crop (such as tomatoes) in the summer, and then grow a winter crop (such as māche) harvested in early spring.
Multiple cropping is less common with field crops because the timing is difficult to manage, particularly since most crop-growing regions experience a good deal of rainfall during the late spring and early summer season, which interrupts fieldwork.
A related practice, companion planting, is sometimes used in gardening and intensive cultivation of vegetables and fruits.
