A field experiment was carried out during the winter growing  season of  2016 - 2017  to study the effect of complete foliar fertilizer CIFOUMIC (10:10:10 NPK). on growth, yield and yield components of barley                      (Hordeum vulgare) (variety. TESSA) under EL – Baida, AL Jabal AL –Akhdar conditions, Experiment was laid  out in a randomized complete block design with three replication, three fertilizer treatments (complete foliar fertilizer, control (Conventional fertilizer recommendation) and foliar fertilizer + 50% Conventional fertilizer recommendation) were applied.  Fertilizer treatments  showed a significant effect on most traits. Data showed that treatment with foliar fertilizer + 50% Conventional mineral fertilizer recommendation  gave the highest value for all growth characteristics, the highest dry weight (2.74 g), flag leaf area (27.5 cm²), chlorophyll content of leaves  (0.061 mg / g) and the highest average growth rate (2.70 g/ day) plant) haight (79.7 cm),number of  spikes /m, (117.3), spike length, (7.00 cm), number of spikelets / spike, (52.3)  grain, biological, Straw yields (1.298, 5:15. 3.85 t/ ha^-1), respectively and 1000  grain weight (48.3 g)
