THE Effect Of Different Percentage Of Chemical Fertilizerson Different Depth Of Soil On the Concentrations Of Trace Element On Leaf Of date Palm ( phoenix dactylifera L.)

Abstract

This study was conducted in Abul Khaseeb at basrah province fellow general date palm board to know the effect of addition of some chemical fertilizers there are urea that supply nitrogen element , super phosphate fertilizer that supply phosphor element and , potassium sulphate that supply potassium element with two ratio( 2:1:1), ( 2:1:2 )( N. P. K) lead to increase the mineral content(Fe , Mn , Cu , Zn )The result showed that fertilization with ( 30 ) cm depth gave significant increasing of mineral content in leaves of date palm .Statistical analytical results showed that fertilization with ( 30 ) cm depth and ( 2 : 1 : 2 ) ( N. P. K ) superior significantly in mineral content(Fe , Mn , Cu , Zn) in leaves of offshoots of date palm C.V.Barhi.
