It occupies sixth and third position as a source of edible oil and vegetable protein in the world respectively. India ranks first in oilseed production in the world and oilseed sector is the prime sector governing the agricultural economy of the country. Groundnut is also known as king of oilseeds and it belongs to the family Leguminosae and sub-family Papilionoideae. The scientific name of groundnut (Arachis hypogaea L.) is taken from the Greek word “arachis” which means legume and “hypogaea” means below ground, indicating to the development of pods in the soil. Groundnut is also referred as poor men‟s cashew nut and wonder nut as well as International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 02 (2018) Journal homepage: http://www.ijcmas.com The experiment was conducted on intercropping of spring groundnut ( Arachis hypogaea L.) with spring groundnut + maize (fodder), spring groundnut + cowpea (fodder), spring groundnut + cluster bean (fodder), sole spring groundnut sole maize (fodder), sole cowpea (fodder) and sole cluster bean (fodder) in spring season of 2016 at research farm, department of agronomy, Punjab Agricultural University, Ludhiana. Two genotypes of spring groundnut comprise TAG 37 A and SG 99 were taken in main plots and seven intercropping systems in sub plots in a split plot design with three replications. Land equivalent ratio (LER), Area time equivalent ratio (ATER), aggressivity (A), competitive ratio (CR), monetary advantage index (MAI), the difference was non-significant in TAG 37 A and SG 99 genotypes. LER, ATER, aggressivity (A) revealed that, all applied intercropping efficient than sole cropping. The lowest amount of competition index (CI) (1.60) was observed in the treatment of spring groundnut + maize (fodder). The highest amount of MAI (39210.6) was observed in the treatment of spring groundnut + maize (fodder).
