الملخص EN

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)
