Intercropping is a multiple cropping practice that involves the cultivation of two or more crops simultaneously on the same field, a form of polyculture. [1] [2] The most common goal of intercropping is to produce a greater yield on a given piece of land by making use of resources or ecological processes that would otherwise not be utilized by a single crop.
Intercropping of coconut and tagetes flowers Agrivoltaic system. The land equivalent ratio can be used whenever more than one type of yield can be obtained from the same area. This can be intercropping of annual crops (e.g. sorghum and pigeonpea) [1] or combination of annual and perennial crops e.g. in agroforestry systems (e.g. jackfruit and ...
When multiple crops are grown simultaneously, this is also known as intercropping. This cropping system helps farmers to double their crop productivity and their income. [ 1 ] But, the selection of two or more crops for practicing multicropping mainly depends on the mutual benefit of the selected crops.
Polyculture is the growing of multiple crops together in the same place at the same time. It has traditionally been the most prevalent form of agriculture. [1] Regions where polycultures form a substantial part of agriculture include the Himalayas, Eastern Asia, South America, and Africa. [2]
The "push" in the intercropping scheme is provided by the plants that emit volatile chemicals which repel stemborer moths and drive them away from the main crop (maize or sorghum). The most commonly used species of push plants are legumes of the genus Desmodium (e.g. silverleaf Desmodium, D. uncinatum , and greenleaf Desmodium, D. intortum ).
The USDA National Agroforestry Center co-funded a program that lasted for 6 years, which assisted farmers in the development of agroforestry plans. Meanwhile, SARE furthered their funding of research on revolutionary agricultural methods and technology by awarding grants to graduate students' research projects nationwide. [4]
The combination of knowledge and practices of agriculture and forestry, resulting in a system of land use in which forest trees or shrubs are grown around or among agricultural crops or pastureland, with the goal of enhancing the functionality and sustainability of a farming system. Agroforestry shares principles with intercropping but may ...
A well-studied example of an agroforestry hillside system is the Quesungual Slash and Mulch Agroforestry System in Lempira Department, Honduras. This region was historically used for slash-and-burn subsistence agriculture. Due to heavy seasonal floods, the exposed soil was washed away, leaving infertile barren soil exposed to the dry season.
