 A field experiment was carried out in the district of Tarmiyah / Baghdad governorate to study the effect Levels of two types of organic fertilizer sheep manure, poultry manure on the growth, yield and oil traits of two sesame varieties Sesamum indicum L. for the Sammer season 2020. The experiment was applied according to the Randomized Complete Block Design (R.C.B.D) with Split Plot System, using two varieties of sesame (Ishtar and Babel) and two types of organic fertilizer (sheep manure, poultry manure) with four levels for each of them are (0, 6, 8 and 12 tons. ha-1), where the best was recorded. The significant superiority of Babel variety in the interferences with the fertilizer level (12 tons. ha-1) for the two types of organic fertilizers mentioned in the traits of each of the plant height, the number of branches in the plant and the percentage of ash, whose mean was (171.54, 183.17 cm and 6.98, 8.41 branches. plant-1 and 4.06, 3.73%) respectively. While the superiority was the best the most significant among the Ishtar variety by interferences with the level (12 tons. ha-1) for the two types of organic fertilizers in the traits of each of the number of capsules per plant (136.13 and 145.24 capsule. plant-1), respectively, the number of seeds per capsule (66.98 and 70.12 seed. capsule-1), respectively, and the weight of 1000 seeds (4.54 and 5.40 gm) respectively and total seed yield (2.69 and 2.81 tons.  ha-1), respectively, and oil percentage (57.39 and 60.03%) respectively.

This study was conducted in the spring seasons for 2011-2012 in privet farm in AL-Ramadi , AL-Anbar distrect near Euphratis never using potato tuber seed Solanum Tuberosum L. cultivar Desiree Elite . the tuber seed was planted using (RCBD). after tuber sprouting and all the diseased and physiological desorderd tuber was removel in 16 / 2 / 2011 and 27 / 1 / 2012 for both season respectively . The stady consist 16 treatment in the first season and 20 treatments in the second season . The treatment included 4 and 5 level of fertilizers given to the field for both season respectively . these treatment are , the control , catle manure , poultry procced manure and the chemical fertilizers and the mixture of the fertilizers in the second season , and the foliar sprays at 4 levels and these are the contrel treatment , foliar sprays with licorice extract at arate of 4 g.l-1, licorice extract + liquid organic fertilizer Leili 2000 and the liquid organic fertilizer Leili 2000 alone at arate of 1 ml.l-1 .
The experimental results showed that :
The chemical fertilizer significantly in hanced the vegetative growth characters such as plant hight , leaf area , dry weight of plant which reached 80.70 cm , 44.52 Des2 , 66.16 g respectively , while the mixture of the fertilizer in the second significantly increased the number of stem , plant hight , leaf area at the rates of 3.42 stem.plant-1 96.94 cm and 92.83 Des2 respectively . The foliar sprays with organic liquid fertilizer 2000 Leili significantly increased dry weight of plant , the percentage of phosphorus in the leaves at the rates of 54.26 g , 0.053 % respectively . The interaction between the chemical fertilizer and licorice extract and the organic liquid fertilizer Leili 2000 in the first season significantly increased the number of tuber per plant , plant yield , marketable yield and total yield at the rates of 11.84 tuber.plant-1 , 0.52 kg.plant-1 , 21.00 ton.ha-1 and 26.16 ton.ha-1 .
