Abstract:
In pot experiments with broad beans (V. faba minor) the effect of increasing N fertilizer rates (0-800 mg N/pot) on nodulation, symbiotic N assimilation, plant growth and yield was studied. The plants were harvested at the beginning and at the end of flowering and at maturity. No significant yield differences between treatments were found at the 1st and 2nd harvest, with the exception of the 800 mg N/pot treatment which gave higher root yields at the 1st harvest. At the 1st harvest (beginning of flowering) root nodule yield of the N-zero treatment was higher than the root nodule yield of the N treated plants. At later stages, however, no major differences in root nodule yield between the treatments N100 and N200 and the N-zero treatment were obtained. Highest grain yields were obtained in the treatment with the lowest N-rate (100 mg N/pot) and in the treatment with the highest N rate (800 mg N/pot). The absolute highest amount of symbiotically fixed N was produced in the low N treatment (100 mg N/pot). [Total soil N was fairly constant throughout the growing period.].
