Influence of nitrogen and zinc fertilization on the agronomic performance and on the crude protein and zinc concentration of IPB Var 1 corn variety

Abstract

The effects of zinc and nitrogen fertilization on the agronomic characteristics of corn; the relationship between nitrogen and zinc fertilization, and the uptake of nitrogen and zinc by the plant as indicated by the concentrations of protein and zinc in leaves and grain, and the effects of nitrogen and zinc fertilization on zinc concentrations in leaves and grain at different growth stages were studied at the experimental field and the chemical laboratory of the College Of Agriculture, Central Philippine University, Iloilo City, Philippines, from December 12, 1981 to April 12, 1982.
