A field experiment was conducted with maize Co 1 in a copper deficient soil with recommended
dose of poultry manure (6.25 t ha'l) and FYM (12.5 t ha'l) alongwith application of copper both to
soil (0, 6.25, 12.5, 25 and 50 kg ha'l as CuS04) and foliar spray (0.1 and 0.2% foliar spray on
30th, 40th and 50th days after sowing). The study revealed that application of manures increased
the uptake of Cu, Mn and Zn by grain and straw whereas copper application was found to have
antagonistic effect on Zn, synergistic and antagonistic effect on Mn and non-significant effect on
iron.
