Zinc content and phytomass accumulation in green corn fertilized with zinc sulphate
The low levels of zinc (Zn) in Brazilian semi-arid soil is one of the factors that most affect the yield and nutritional quality of the maize. The aim was to evaluate the influence of Zn doses via root and leaf on the production of phytomass and Zn contents in leaves and grains of green corn growing in alkaline soil. Two experiments were carried out under field conditions, in a randomized block design, with four blocks. In the first experiment five doses of Zn (0; 2.5; 5.0; 7.5 and 10.0 kg ha-1) via soil, were tested.
