EFFECT OF FOLIARUREA AND CHELATED IRON ON GROWTHOF WASHINGTONIA SEEDLINGS

Abstract

Experiment was conducted in wood shed of agriculture college - Basrah university - Iraq to study the effect of three average of urea (0 , 50 , 100)mg /L/seedlings/year and three average of iron (0 ,25 , 50)mg /L/seedlings/year , and their interactions on physical and chemical of Washingtonian seedlings . Results indicated that . Interaction between urea and iron had significant effects in the number of leaf and area of leaf , the treatment(100mg urea/L +50mg Fe/L) gave higher average of( number of leaf( 9.00) and area of leaf( 0.229.20cm²). compared with other treatments .Results showed the interaction between urea and iron treatment(100mg urea/L +50mg Fe/L) had significant effects in increasing leaves content of chlorophyll 0.1769% and leaves content of protein( 6.125%)but leaves content of carbohydrate 2.613% resulted by the treatment ( 50 mg urea+50 mg iron)L compared with other treatments.
