| Abstract | ||
| 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 . | ||
