Leaf Nutrient Concentrations Among Progenies of Interspecific Oil Palm Hybrid

Abstract

The objective of this work was to evaluate the variation in diagnostic leaf nutrient concentration of oil palm interspecific hybrid (Elaeis oleifera x Elaeis guineensis -HIE OxG) progenies and its effect on fertilizer recommendation. A plant nutrition study was conducted in a plant breeding experiment installed at a farm of the Grupo Marborges, Moju municipality, Pará state, Brazil. Significant differences were observed in K, Mg, B, Cu and Mn concentrations in the leaves among the progenies evaluated. The variation on K and Mg concentration in the diagnostic leaf influenced the fertilizer recommendation based on the criterion of the leaf analysis.
