Two field experiments were conducted in 2006 at five
locations in Mississippi to evaluate sunflowers as oilseed crop for biodiesel
production. The first experiment
evaluated the effect of location, variety, and N rate application, while the
second experiment evaluated the effect of location, variety, and seeding
date. Four and nine conventional
sunflower varieties were used in the first and the second experiment,
respectively. The N rates in the first
experiment were 0, 60, 120, and 180 kg/ha.
The seeding dates were in April, May, and June for both
experiments. The first experiment was
conducted in Newton, Stoneville, Starkville, and two locations in Verona,
MS. The second experiment was conducted
in Beaumont, Newton, Starkville, and two locations in Verona. Overall, the first seeding date was
successful and resulted in relatively good seed yields from all sunflower
varieties in all locations. Due to the
drought conditions in early summer of 2006, the second and the third seeding
date did not establish in all locations, and the yields were low. Potential production issues with sunflower
production in Mississippi seem to be the control of black birds, some insects
such as stem borers, and control of nutsedge, morning glory, and some
grasses. Our one-year multilocation
data suggest that sunflowers could be a viable oil seed crop for biodiesel
production in most parts of Mississippi.
