EFFECT OF NEWER SOURCES OF ZINC APPLICATION ON Zn, Mn, Cu, Fe UPTAKE BY RICE (VAR IR.60) IN LOWLAND

Abstract

Zincated urea and zincated suphala were evaluated along with the zinc sulphate for the uptake of micronutrients such as Zn, Mn, Cu and Fe by rice (Var IR.60) in a deficient (DTPA extractable Zn 1.1 ppm) clay loam soil (Typic Haplustall) at Tamil Nadu Agricultural University, Coimbatore, India. The data revealed that zinc fertilization increased Fe, Mn, Cu and Zn uptake with other nutrients indicating synergistic effect. Among the sources of zinc, zincated urea applied alone provided higher value for copper uptake but in combination with zincated suphala provided the highest value for Zn, Fe and Mn uptake.
