Abstract

A pot experiment was conducted on alluvial and calcareous soils to study the effect of soil and foliar application methods of zinc added at the rates of (0, 5, 10 and 20 ppm) as zinc sulphate on fresh weight and dry matter of corn (Giza 204) plants and on the content and uptake of nitrogen, phosphorus and some micronutrients. Increasing zinc fertilization level up to 10 ppm increased fresh weight and dry matter yield as well as content and uptake of N, P and some micronutrients by corn plants grown in different soils under study. Fresh weight and dry matter yield as well as different nutrients content and uptake by corn plants were significantly affected by differ­ent interactions under investigation.
