This study was conducted in the Research Center and Agricultural experiment Agriculture College / University of Kirkuk in Sayda area .

During seasons the growth 2017-2018 of period 1 / 12 / 2017 to 15 / 6 /2018 .

To study the effect of add Fertilization Mineral /NPK/ and humic acid on the vegetative growth and leaves chlorophyll of Young Navel Orange trees .The similar trees Young Navel Orange were selected in growth force, which were brought up in a lunar way and were planted on lines /5 × 5 m/ Using the Randomized Complete Block Design /RCBD/ with three replicates .

To study the effect of three levels of add Fertilization Mineral /NPK/ /Jordan Dab/ the concentrations /0 : 46 : 18/ first level /zero / tree /, second level /50 g / tree/ and therd level /100 g / tree/ in 1 / 12 / 2017 , humic acid was add of in three concentrations /0 , 3 and 6 g /L / .

The results showed that add Fertilization Mineral /NPK/ level of /100 g / tree// led to increase the length and demeter of stem /16.71 , cm Length and1.50 cm/ and length and demeter /15.14 cm Length and 0.89 cm Demeter/ and leaves chlorophyll /23.16 SBD/ and the large of leaf area /37.63 cm2/ and dry weight of leaf /5.66 g/ .

While, concerning of the humic acid the results showed that 6 g /L humic acid led to increase also the length and demeter of stem , leaves chlorophyll and the large of leaf area and dry weight of leaf in the leaves as compared to the comparison treatment .

On other hand, Interaction between add Fertilization Mineral /NPK/ level of /100 g / tree/ + 6 g humic acid / L gave the best results which led to significant increase in all the studied parameters in the length and demeter of stem , leaves chlorophyll , the large of leaf area and dry weight of leaf for growth season.
