Abstract

The field experiment was conducted in Anbar governorate /Fallujah city 60 kmwestern of Baghdad onEuphratesriver bank 20th of Januaryduring thespring seasons from 2013 and 2014 Potato tubers of Burren CV. (class Elite) were planted for tow above seasons and the experiment was conducted depending on Randomized Complete Block Design (RCBD) and the results were tested depending on the lest significant differenceL.S.D on probability level 5%.
The chemical fertilizer treatment T14 (400.120.240)(NPK) recorded a high fresh weight in both of season to 53.96 gm and the potassium treatment T10 250 m.l-1increase the plant hight up to 60.03 cm for (gm) first season 53.96(gm), while the CK treatment 10 m.l-1T9 effect in vegetative growth characters like number of stems per plant and leave area (cm) 2 for plant in both seasons which reached to 4.30 stem/plant and 11327 cm2 and 4.50 stem/plant and 12073 cm2 respectively. The salicylic acid treatment 250 m.l-1T7 showed a high chlorophyll ratio in leaves for two seasons to (52.73 and 54.83 SPAD-UNIT).Respectively. The CK treatment T9 10 m.l-1 and Amino Acid treatment T13 500 m.l-1given a high ranges of tuber numbers were recorded9.30 and 9.50 tuber/plant for both seasons respectively,
while the Amino Acids treatment T12 250 m.l-1 gave a high average in tuber weight and plant yield for the first season were reached 166.90 gm and 1050 km per plant, the salicylic acid treatment T7 250 m.l-1gave high average of marketable yield for both season to 31.55 and 32.42 ton/harespectively and the Amino Acids treatment T12250 m.l-1 gave high average of total yield was reached 46.95 ton/ha for the first season.
