Effect of humic, and fulvic acid spraying on iron availability in soil and corn growth and productivity

Abstract

A field experiment was conducted at College of Agriculture, Univ. of Al-Muthanna.during 2015 growing season. The objective was to investigate the effect of foliarapplication of HA and FA on availability of Fe in soil, its accumulation in plant tissue,plant heights, plant dry weight, chlorophyll content and final yield of corn. The resultsshowed that spraying plants with HA and FA acid resulted in higher Fe concentration insoil and plant tissue, plant height, chlorophyll content and final yield as compared tocontrol.
