Summary Plant and nodule development nitrogen fixation were studied in two climbing cultivars of Phaseolus vulgaris , grown monoculture, or associated with maize populations differing growth characteristics. Bean cultivar P590 showed similar plant pod fresh weight monoculture when a vigorous landrace maize, interspecific competition becoming significant only 92 days after planting. Nitrogen (C 2 H ) this was greatest 68 planting declined rapidly thereafter, showing no differences between plantings. When the bean P526 depressed as early 50 While slight inhibition fixation, specific activity (SNA) carbohydrate content also observed at time, it could not be concluded that such definitely due to Association an improved amarillo subtropical, did affect but decrease 80 day harvests.
