Abstract

Nickel is essential element in low concentration for maize plant growth while at high concentration it is toxic. The level of nickel toxicity on root, shoot length and dry biomass of maize was studied, compared to control. A pot (60days) and solution culture experiment (20 days)were conducted to study the effect of nickel concentration on maize plants. Seeds of maize were exposed to a range of nickel levels (0, 10, 20, 30 and 40 mg L-1) prepared in Hoagland nutrient solution and in pot experiments black soil were spiked with the (0, 50, 100, 150, 500 and 600 mg kg-1) metal solution of different concentrations of nickel. The study revealed that dry matter yield of maize was decreased at 10 mg L-1 nickel in solution culture, while in pot culture study, 50 mg kg-1 nickel concentration recorded reduced dry matter weight and also chlorosis symptom was observed at nickel dose above 100 mg kg-1The aim of this study was to determine how to nickel reduces maize growth. We examined Ni accumulation and distribution in maize plants and the effects of toxic concentrations on growth and biomass.
