The response of the apricot tree to combinations of fertilization with Qrop
Complex and foliar spraying with seaweed extract (Alge-Zone) and their interactions in
some chemical and yield traits are discussed. This includes the content of leaves Of
chlorophyll and nutrients, Fruit weight (g), yield per tree kg. tree -1, percentage of total
soluble solids (T.S.S). The randomized complete block design (R.C.B.D) was used with
three replicates including the least significant difference (LSD) to compare the means at
the 0.05 probability level. The results showed that the ground fertilizer with Qrop Complex
gave an increase in the studied characteristics, and the foliar spraying with seaweed extract
(Alge-Zone) had a positive effect on each of the leaves’ content of chlorophyll and
nutrients (nitrogen, phosphorous, potassium, boron and iron). Fruit Weight (g), The yield
of one tree kg. tree -1, the percentage of total soluble solids (T.S.S). As for the interaction
treatment, the ground fertilization with Qrop Complex fertilizer (600 g.tree-1) and foliar
spraying with seaweed extract (Alge-Zone) at a concentration of 3 ml. L-1 significantly
excelled in giving the best results in the studied traits which the content of leaves Of
chlorophyll (54.67 SPAD), content of leaves Of nutrients (nitrogen, phosphorous,
potassium, boron, and iron) of (1.60%, 0.47 %, 1.59, 50.30 mg.kg-1 and 251.67 mg.kg1) respectively, Fruit weight of (16.96 g), yield per tree (15.77 kg. tree -1) and percentage
of total soluble solids (T.S.S) of (15.66).
