An experiment was carried out in one of the private fields in Amiriya (10 km south of Fallujah), Anbar province, to study the effect of spraying some organic fertilizers on growth , yield and quality of three potato cultivars during spring season of 2010, seed tubers (class Elite) were planted at 6-2-2010. Plants were spread at 45 days and 65 days from sowing. Use the randomized block design full RCBD (Randomized Complete Block Design) with three replicates, the means were compared according to L.S.D. test at 5% significant level.
Spraying of Bepton was superior in plant length 104.44 cm, leaf area 49.86 dm2, chlorophyll 49.18 SPAD unit, number of marketable tubers plant 6.67 tubers, total plant yield 889.1 gm, dry matter 16.88 %, starch 11.56% and specific density 1.0640 g/cm3 , compared with Bihorm solution. Desiree cv. was superior in plant length 114.56 cm, marketable tubers yield plant 630.1 gm, dry matter 15.93 % and specific density 1.0594 g/cm3, compared with Avalon and Arizona cv.
