Abstract

A field experiment was carried out during the winter season 2012-2013 in fields of Agriculture College - University of Tikrit, to study the effect of addition levels of Organic and chemical Fertilization on the special characterizes for the growth, yield seeds, of fennel (Foeniculum vulgare L.) by using Organic Fertilization (cow manure) with two levels (0, 6 ton. hectar-1 ,cow manure) and chemical Fertilization(Phosphors) in the form of Triple super phosphate (21 % P2O5) with two levels (0, 100 kg. hectar-1 ) and it's interactions, The experiment carried out based on the system of testing the factorial experiment has been used according to randomized complete block design (R.C.B.D) with three replications. The results can be summarized as follow: The treatment (M1) (6 ton. hectar-1 cow manure) apparent highest average in an increasing percentage on all characterizes, plant height (11.12%), dry weight (24.47%), the number of flowers umbels (24.25%). the addition Phosphors during (P1) (100 kg. hectar-1 ) treatments gave highest percent in, plant height ( 4.61% ), the number of flowers umbels (8.11%)
