This research work was carried out at the Center for Agricultural Scientific Research, in Tartous, in spring season 2018, by studying the effect of organic fertilization of mixing and adding two levels of dry biogas manure (B), (40 and 120 m/h) with two levels of tobacco compost (T), (20 and 40 m/h), as well as the control treatment without fertilization, on growth and productivity of potato crop (cult. Spunta). The Completely Randomized Design was adopted in this work, with three replicates for each treatment and 27 plants per replicate. The results showed a positive effect of adding the mixture of biogas manure and tobacco compost on improving the productivity and tubers quality of the potato crop. Where The mixed treatment of both biogasmanure and tobacco compost(40 m+40 m/h,gave the highest values for tubers production per plant (640 g/plant), and the unit area production (3.657 kg /m ) and tubers quality of market production, (3.326 kg/m). Also, gave the highest percentage of dry matter and starch contents in tubers (23.09%, 16.59%) respectively, and the lowest content of nitrate 137 mg / kg in potato tubers.
