Abstract
Crop rotations of 4 to 6 years have been commonly recommended
for sunflower. Some authorities suggest shorter rotations
when disease-resistant hybrids are used. Many sunflower
producers use a 3-year rotation, some use a 2-year rotation, and
some are considering monoculture.
Monoculture is the antithesis of crop rotation. It consists of
growing the same species of crop for two or more years on the
same field. Crop rotation is a recurring succession of crops on
the same field. Rotations vary in length from 2 to 6 years or
longer. The shortest rotation, 2 years, is called crop alternation.
Crop rotation provides diversification of risk and labor for
the individual farmer. Farmers often change rotations or crop
sequence in the rotation to meet federal farm program requirements
or in response to anticipated changes in prices of crops.
The objective of a good crop rotation or sequence for sunflower
is weed, insect, and disease control.
