The cultivars and breeding lines were variable in terms of their N. fixation. The cv. Caballero was very efficient, with more than 50% N derived from the atmosphere and 60–80 kg N ha. fixe

There were significant differences between lines and correlations between trials were significant for the amounts of N. fixed, but not for total shoot nitrogen. The plants that fixed the mos

The Phenomenology of Moods in Kierkegaardture during the reproductive stage and sometimes during the vegetative stage. The objective of this experiment was to study the effect of drought on nodulation, N. fixation and grain yield of beans. The cultivars evaluated were: Flor de Mayo Bajio, Bayocel, Bat-477 and Honduras-35. The treatments we
