Sunflower is a fairly fast maturing crop with most varieties taking 85 to 100 days to maturity. The crop is popular for its oil which is clean and light with high level of linoleic acid (an essential fatty acid). Sunflowers can be grown as a full season single crop or an intercrop with maize, soybeans and/or sorghum.
Regardless of whether they are grown as a single crop or an intercrop, sunflowers should not be planted in the same field more than once every three to four years. Sunflowers, like soybeans, do not leave much residue, so on erosive fields consider planting a cover crop after sunflowers.
