Companion planting is the planting of different crops in close physical proximity (in gardening and agriculture), on the theory that they assist each other in nutrient uptake, pest control Pest control refers to the regulation or management of a species defined as a pest, usually because it is perceived to be detrimental to a person's health, the ecology or the economy, pollination Pollination is the process by which pollen is transferred in plants, thereby enabling fertilisation and sexual reproduction. Pollen grains, which contain the male gametes to where the female gamete(s) are contained within the carpel; in gymnosperms the pollen is directly applied to the ovule itself. The receptive part of the carpel is called a, and other factors necessary to increasing crop productivity.

Although there is a wealth of information on its historic use, there remains limited available scientific research on the effectiveness for each of these interventions.[1] [2] [3] [4]

Companion planting is used by farmers and gardeners in both industrialized and developing countries for many reasons. Many of the modern principles of companion planting were present many centuries ago in the cottage garden.

For farmers utilizing an Integrated Pest Management In agriculture, integrated pest management is a pest control strategy that uses a variety of complementary strategies including: mechanical devices, physical devices, genetic, biological, cultural management, and chemical management. These methods are done in three stages: prevention, observation, and intervention. It is an ecological approach system, increased yield and/or reduction of pesticides A pesticide is a substance or mixture of substances used to kill a pest. A pesticide is any substance or mixture of substance intended for: - preventing, destroying, repelling or mitigating any pest. A pesticide may be a chemical substance, biological agent , antimicrobial, disinfectant or device used against any pest. Pests include insects, plant is the goal[citation needed].

In the developing world Developing country is a term generally used to describe a nation with a low level of material well being. There is no single internationally-recognized definition of developed country, and the levels of development may vary widely within so-called developing countries, with some developing countries having high average standards of living, tropical crops are used instead of temperate ones and provide NGOs and other organizations a tool for alleviating poverty[citation needed].

For gardeners, the combinations of plants also make for a more varied, attractive vegetable garden. It can also be used to mitigate the decline of biodiversity.[citation needed]

Companion planting is considered to be a form of polyculture Polyculture is agriculture using multiple crops in the same space, in imitation of the diversity of natural ecosystems, and avoiding large stands of single crops, or monoculture. It includes crop rotation, multi-cropping, intercropping, companion planting, beneficial weeds, and alley cropping[citation needed].
