Abstract

2 experiments to investigate the requirements of sorghum and groundnut grown on Malaysian peat soil for Cu, Mn, Zn, Fe, Mo and B are described. The first experiment showed that only Cu was needed when growing sorghum and groundnut on peat. Plant survival and seed and total DM yields were greatly improved by applying 20 kg CuSO4/ha. Application of Cu also enhanced the absorption of Cu, Fe, Zn and Mn. The 2nd experiment showed that 10 kg CuSO4/ha produced the same effects on crop yields as 20 kg/ha. Sorghum leaf Cu content was increased from about 16 p.p.m. to about 28 p.p.m. by the addition of 10 or 20 kg CuSO4/ha. Groundnut leaf Cu content was similarly increased from 3.6 p.p.m. to about 4.5 p.p.m. In both experiments, each crop of groundnut or sorghum only recovered c. 20-30 g/ha of the applied Cu
