Abstract

Pot and field studies to investigate the effects of lime, inoculation and lime-pelleting of seeds on the establishment of I. leucocephala were carried out. In addition, ClRP pelleting and phosphorus treatments were included in the field study. Under pot conditions, both the introduced cultivars gave significantly, higher yield than the local cultivar, but all cultivars showed similar responses to all the treatments. On the Serdang Series,liming and inoculation significantly increased yield under pot and field conditions. A similar response was observed on the Bungor Series under pot conditions. Lime-pelleting of inoculated seeds in the presence of lime significantly, increased yield by 39-fold under field conditions but appeared to depress yield under pot conditions. A similar depression of yield was observed on the Bungor Series under pot conditions. ln addition to lime, inoculation and lime-pelleting adequate phosphorus was also required to give optimum yield. Dry matter yield and nodule number were significantly correlated on both the Serdang (r=0.74**) and Bungor (r=0.70**) Series.
