Some Nutrients Concentration of (Nigella sativa L.) As Influenced by Cytokinin and NPK Fertilizer.

Abstract

An experiment was conducted at the field of Biology Department , Education College - Ibn-Alhaitham , Baghdad University during the growing season of 2010/2012 . The aim of the experiment was to assess the effect of four concentrations of cytokinin .i.e.0, 50 , 100 and 150 mg.l-1 and three levels of compound fertilizer NPK i.e.0,160 and 320 Kg.ha-1. on N,P,K,Ca and Mg concentrations of (Nigella sativa L.) plant. Factorial experiment within R.C.B.D. with three replications was adopted i.e.36 experimental units were included . Results revealed that , increasing levels of both factors and their interaction caused a significant increment of the above mentioned nutrients concentration with the surpass of 100 mg.l-1 cytokinin and 320 k.ha-1. fertilizer level on the rest of treatments.
