This study was conducted during the 2019-2020 growing season in the field of the Department of Horticulture and Gardening
Engineering/College of Agriculture and Forestry/University of Mosul, to find the effect of fertilizing with three types of liquid
organic fertilizers (humic acid, Tikamine Max and Neutergreen and four levels for each type) 2, 4, 6 and 8 ml Seedling-1) In
addition to the comparison treatment (not adding) in some of the vegetative growth characteristics and nutrient content of
the grafted apricot seedlings Zaginia cultivar, the implementation of the study followed the design of complete randomized
sectors (RCBD) with three replicates and by using three seedlings per experimental unit, organic fertilizers were added
Mentioned above and Transactions twice in the season (beginning and end of April), the results confirmed that all studied
traits were significantly affected by the addition of liquid organic fertilizers, whereby fertilizing with 8 ml. Liters-1 of Neutergreen
fertilizer gave the highest averages of (increase in height and diameter of seedlings, nitrogen ratio and content Iron in leaves),
and fertilizing with 4 ml.Liters-1 of Neutergreen fertilizer gave the highest chlorophyll content and phosphorous ratio in the
leaves, while fertilizing with 6 ml.Liters-1 and 4 ml.Liters-1 of Tikamine Max fertilizer resulted in Significant increase in potassium
and zinc content in the leaves respectively.
