7833. Koala, S.. 1985. Effects of N and P fertilizers on the growth, nodulation, and N2 ixation of fababean, green pea, and dry bean.. PhD. Thesis, Dept. of Plant and Soil Sci., Montana St. Univ., Bozeman, MT 59717.

7871. Lockerman, R.H., T.J. Kisha, J.R. Sims, and A.S. Abdel-Ghaffer. 1983. The effect of soil salinity on dinitrogen fixation and yield of fababean.. FABIS 7:24-25.

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.

8907. Bremer, E., R.J. Rennie, and D.A. Rennie. 1988. Dinitrogen fixation of lentil, field pea and fababean under dryland conditions.. Can. J. Soil Sci. 68:553-562.
N15 was used to study the N-fixation of several grain legumes in Saskatchewan, with all major soil zones represented. Indigenous rhizobia were incapable of supporting adequate levels of N2 fixation at most sites. Inoculation increased total dry matter, total N, and N2 fixation of all legume cultivars tested. Annual rates of N2 fixation were as high as 75, 105, and 160 kg N/ha for lentil, pea, and fababean, respectively on gray and gray-black soils in one year, but declined by an average of 5.3, 7.6, and 10.5 kg N/ha, repsectively, for every cm reduction in moisture use. Fababean fixed the most N under wetter conditions, while pea and lentil fixed the most under drought stress conditions. The amount of N fixed was not significantly correlated with soil nitrate levels in either year, perhaps due to the overriding effects of moisture. Estimates of the % plant N derived from atmospheric fixation ranged from 30-80%, with fababean generally the highest. The % from atmosphere was negatively correlated to soil nitrate for pea and lentil.
