This research was conducted in Lattakia province during the year 2012 first, to identify the current status of the production residues and agro-processing materials in the province and, second, to introduce modern methods of taking advantage of them and raising their nutritional value. Results showed that, the most agricultural residues are not optimally used, instead, they were disposed and accumulated causing substantial losses and environmental pollution. Results showed that, the investment average ratio of legume, vegetables, cereals, and fruit trees were 75%, 65%, 60% and 40% consensually This research conclusion shows that, the optimal use of barley residue is a source of cheap protein units that are necessary for animals feeds; where the cost per unit of digested protein resulting from urea treated hays amounts to 0.5 S.Y.P. This amount represents one fifth of the cost of protein unit from barley. Also, the use of wheat straw in the cultivation of oyster mushrooms achieve significant economic results, the net profit resulting from the cultivation area of 10 m2 of oyster mushrooms using 30 kg of wheat straw was about 81000 S.P. In addition to that, the research results show the importance of agricultural waste in biogas production and the resulting compost, which in turn has achieved excellent results when fertilizing crops with it. The increase in the yield of maize, wheat, faba bean and vegetables were 35.7%, 12.5%. 6.6% and 14.1-20.6% consensually.
