Breeding Legumes for Enhanced Symbiotic Nitrogen Fixation: Proceedings of an FAO/IAEA Consultants' Meeting, held in Vienna, 26-30 September 1983

Adequate nitrogen fertilization is needed to obtain maximum crop yields. Without sufficient nitrogen available to the plant, other inputs are wasted. There are great differences between developed and develop­ ing areas of the world with regard to nitrogen-fertilizer production and application, resulting in serious food deficits in some of the most needy areas. Although nitrogen fertilizer is an inexpensive input in comparison to the resulting yield increases, chemical fertilizers must be pu...
