Abstract
The research was carried out in the lath house of the Technical College, Al-Musaib during the 2018-2019 growth season to study the effect
of bio-composting and foliar spraying with nanoparticle on the vegetative and root growth of grafted Orange seedlings on Citrus aurantium
origin the experiment included two factors, the first is the use of four types of earthly addition with biological fertilizer these are (control
treatment, Azotobacter bacteria 10 ml. L-1, mycorrhiza fungi 10 g, treatment of interference between Azotobacter bacteria 10 ml. L-1
,
Mycorrhiza fungi 10 g) to the one pot As for the second factor, it is sprayed with chelated nano fertilizer (micronutrients) with several
concentrations (control treatment, 1 g.L-1 l, 2 g.L-1.3 g.L-1). Therefore, the experiment included (16) treatments, three replicates, and three
seedlings per refined, for a total of 144 seedlings per experiment. The seedlings were sprayed three times for the spring and autumn dates.
Untreated seedlings (control) were sprayed with distilled water only. The experiment was performed according to Completely Randomized
Design (CRD) with two factors (4 × 4), the results were analyzed using the ANOVA table of variance analysis according to the Excel
program. Statistical differences between the treatments were tested using the least significant difference (L.S.D) at the 5% probability level.
The results of this study can be summarized as follows: (1) The combined treatment with Mycorrhiza and Azotobacter resulted in a
significant increase in the vegetative traits, which include plant height, stem diameter (vegetative), as well as an increase in the root and
represented traits (number of roots, length of the main root, dry weight of the root system) and chemical characteristics (leaf content of
chlorophyll). (2) The reason for spraying with nano fertilizer 3 g.L-1 significant increase in the vegetative and root traits and the leaf content
of chlorophyll). (3) The treatment of the interaction between the treatment with Mycorrhiza and Azotobacter combined with spraying with
nanostructures achieved 3 gm.L-1 significant increase in vegetative traits plant height, stem diameter reached (54.23 cm, 5.20 cm). The same
treatment also gave a significant increase in the root traits (main root length, number of roots, and dry weight of root root) (51.80 cm, 3.99,
9.87 g). The same treatment gave a significant increase in the leaf content of chlorophyll (60.93SPAD).
