الملخص EN

The objective of this study was to investigate the effect of foliar nutrition on fig sapling growth of cv.

waziry at the College of Agricultural Engineering Scicences A factorial experiment within Randomized Complete Block Design with three replicates was used during the seasons of 2017-2018, using fig seedlings by spraying fertilizers (Foliartal) with four concentrations (0, 2, 4, 6 ml.L-1) and organic fertilizers (Tecamin Max) with four concentrations (0, 3, 4, 5 ml.L-1).

Results revealed that application folir of chemical fertilizers caused an increases in plant growth.

the highest concentration (4 ml.L-1) was the most effect leading to a significant increases in plant height (19.74, 27.46 cm), stem diameter (3.43, 5.85 mm), leaves area (40.30, 68.47 dm2), and leaves chlorophyll content (219.4, 277.4 mg.100 g-1) The treatment(6 ml.L-1) led to the highest significant increases in nitrogen (2.13, 2.63 %), phosphorus (0.86, 0.93 %), potassium (2.50, 2.99 %) and amino acids (3.77, 6.17 % ) for both seasons, respectively Foliar organic fertilizer applied (5 ml.L-1) with amino acid significantly increased plant height (13.39, 19.50 cm), nitrogen (2.11, 2.57 %), phosphorus (0.78, 0.81 %, potassium (2.90, 2.34 %)contents, and the leaves area for the first season (42.65 dm2).

While the concentration (4 ml.L-1) indicated a significant increases in stem diameter (3.43, 5.23 mm),leaves chlorophyll content (202.3, 281.2 mg.100 g-1 )fresh weight and amino acid (4.05, 6.26 %) for both seasons and leaves area (67.88 dm2) for the second season.

the interaction treatments had a significant effect on all the vegetative growth traits.
