POLYCULTURE is agriculture using multiple crops in the same space, providing crop diversity in imitation of the diversity of natural ecosystems, and avoiding large stands of single crops, or monoculture . It includes multi-cropping , intercropping , companion planting , beneficial weeds , and alley cropping . It is the raising at the same time and place of more than one species of plant or animal. Polyculture
Polyculture
is one of the principles of permaculture .

ADVANTAGES

Polyculture, though it often requires more labor, has two main advantages over monoculture.

Polyculture
Polyculture
reduces susceptibility to disease. For example, a study in China
China
showed that planting several varieties of rice in the same field increased yields by 89%, largely because of a dramatic (94%) decrease in the incidence of disease, which made pesticides redundant.

Polyculture
Polyculture
increases local biodiversity . This is one example of reconciliation ecology , or accommodating biodiversity within human landscapes. This may also form part of a biological pest control program.
