Sunflower

Sunflower probably originated in the southwestern United States, or some-where in Mexico, where it was used in many forms. It was introduced to Europe in the 16th century and imported into Russia from Holland in the 18th century (Weiss 1983:402). As a cultivated plant, improved varieties were reintroduced into the USA from Russia in 1893. In Pakistan, sunflower was first introduced as an oilseed crop in 1960's.
Sunflower has been accommodated between the two major crops in a cotton and rice-based cropping system, or on summer-fallow lands. Moreover, sunflower has shown good intercropping compatibility with other crops.
