8877. Dean, J.R. and K.W. Clark. 1980. Effect of low level nitrogen fertilization on nodulation, acetylene reduction and dry matter in fababeans and three other legumes.. Can. J. Plant Sci. 60:121-130.
Acetylene reduction in fababeans was significantly greater than in peas and black beans. The addition of 20 kg N/ha as ammonium nitrate depressed nodulation and nitrogen fixation in all species. N fertilizer produced significant increases in dry matter in all species except fababean.
