| Abstract | ||||
| Two successive field experiments were carried out in 1988/89 and 1989/90 seasons in Mallawi Research Station, using seed soaking treatments of faba bean in different concentrations of nickel as NiSO4 for 24 hours to obtain the optimum concentration for the growth of faba bean plants. Another field experiment and pot experiment were carried out during 1990/91 season to study the effect of this concentration under three levels of nitrogen (0, 7.5 and 15 kg N/fed. in the field experiment or 0, 0.3 and 0.5 g urea/pot in the pot experiment). Concentration of 50 ppm Ni was the most suitable level since it gave the highest number of pods/plant and the highest seed yield/fed. in both seasons. Under N application, it was found that seeds soaking in 50 ppm Ni without N application gave significant increase in seed yield/ fed. or pot and 100- seed weight and increased number of nodules/ plant, dry weight of nodules, dry weight of roots and N content of roots over the control. These parameters were gradually decreased by increasing N rate under soaking treatment. | ||||
