Influence of Simazine on the chemical constitution of mature corn (Zea mays L.)

Abstract

The application of simazine increased the per cent of N, Cu and soluble proteins in corn seeds. A significant increase in the amount of total P in corn leaves and inorganic P in corn seeds noticed by application of simazine @ 1.25 and 2.50 kg ai/ha respectively. Uptake and distribution of K was not affected. Increased uptake of Ca was observed and it was uniformly distributed among different parts of plants, whereas Mg distribution was very much affected by herbicide treatment rather than its uptake. Higher concentration of simazine inhibited the uptake of Fe by corn plants, whereas the Mn absorption was increased. Simazine @ 0.625 kg ai/ha. resulted in the accumilation of Cu in corn seeds.
