Abstract

The objectives of BioTechnica International’s research and development program in nitrogen fixation are to develop seed-coating products for alfalfa and soybean that improve crop productivity. The seed coatings will contain genetically engineered strains of Rhizobium meliloti or Bradyrhizobium japonicum, respectively, with improved nitrogen-fixing and competitive abilities. To accomplish these objectives, several technical and regulatory hurdles must be overcome. Strategies to improve nitrogen fixation and competitive ability must be devised and implemented, the resultant strains must be tested under greenhouse and field conditions, and an appropriate delivery system developed.
