Evaluation of the Nutrient Composition of Maize in Different NPK Fertilizer Levels Based on Multivariate Method Analysis

One of the critical issues in using micronutrient fertilisers is comparison methods and amounts fertiliser use, which very important from aspect increasing production economic viewpoint. The aim this research was to analyse nutrient composition different parts maize (Zea mays L. FAO 490) during growing season with six-level nitrogen fertilisation supplies at five phenological stages. study included essential nutrients as (N), phosphorus (P), potassium (K), sulphur (S) (in first cluster) calcium (Ca) magnesium (Mg) second treatments on leaf stage. Growth stages have demands based their actual demand. cluster zinc NPK stalk plants. Nitrogen had maximum effect season. Magnesium copper were most desirable factors growth relation stalk. impact yield formation stage grain filling quantitative qualitative properties showed that increases dry matter, yield, its components. amount absorption plants occurs before accumulation applied fertiliser, prelude biomass.
