Biodiesel is an alternative fuel that is produced from domestic renewable resources such as vegetable oil or animal fat.  There is a great potential for demand-pull to increase oilseed production if biodiesel production expands. Hence identifying and developing a suitable oilseed cropping system will help the success of the biodiesel industry in the United States and its contribution to energy diversity. The objective of this research is to develop agronomically and economically feasible cropping systems for Mississippi involving Canola (Brassica napus`X B. rapa),Coriander (Coriandrum sativum L.), Oriental Mustard (Brassica juncea) and Sunflower (Helianthus annus L.).  Field experiments were set up at two locations, (Delta Research and Extension Center in Stoneville and North Mississippi Research and Extension Center in Verona), representing two different climatic and pedological zones of Mississippi.  The crops will be grown in a double cropping system producing two oilseed harvests per year.  Mustard, canola and coriander will be grown as winter crops followed by sunflower as a summer annual crop in a two-year rotation. The field experiments include evaluation of four N levels on crop yield, oil content, and fatty acid content of all the crops in each of the cropping system.  In the second experiment, we evaluate the effect of seeding dates, (three in the late fall and one in early spring), on growth and productivity of the oilseed crops in the two Mississippi locations.  In addition, a bi-product utilization study will be conducted to evaluate the anti-microbial properties of coriander extracts and the soil fumigant characteristics of mustard extracts.  These results will help to identify a productive and economical oilseed cropping system for Mississippi growing conditions.  Furthermore, the study will increase our understanding on suitable alternative crops that could be grown as feedstock for the expanding biodiesel industry in Mississippi.
