Pot experiments were carried out on silt loam soils (Inceptisols) to investigate the effect of different levels of nickel and moisture stress on the uptake of nickel by vegetable crops. Pui and kalmi were the test plants. Nickel application influenced the uptake of nickel by kalmi and pui plants. Their content of nickel increased significantly with increasing Ni concentration in soil compared with control. Different levels of moisture also influenced the uptake of nickel. The content of nickel was higher in both kalmi and pui at higher moisture level. Root accumulated more Ni at higher...
