Under in vitro conditions, the trace elements at lowest concentrations (Cobalt 0.5 ppm, copper 1.0 ppm, manganese 1.0 ppm, zinc 1.0 ppm and molybdenum 1.0 ppm) caused 50 to 300 per cent more growth of groundnut rhizobium. Copper at 5.0 and 10.0 ppm level inhibited the growth effectively. The two-way combination of trace elements enhanced the growth of rhizobium significantly; manganese and molybdenum caused the maximum growth. The copper toxicity to the rhizobium seems to be allevi ated by the presence of other trace elements like manganese, molybdenum, zinc and cobalt.
