This project will develop and diversify Crambe (an oilseed crop) and brassica (mustard green) species as dedicated bioenergy crops for biodiesel production. The proposed strategy will increase crop biomass and seed yields while growing these crops on marginal and heavy-metal-contaminated lands, thus increasing both yield and arable acreage. This approach to cultivation on contaminated sites and marginal lands will not create competition for land or displacement of food crops. This study will develop the dedicated biodiesel crops to meet the demand of seed oil for biodiesel production and will also create extra revenues, jobs, and thus will empower the regional and national rural economy.
