| Abstract : An experiment was carried out in one of the private field in Al-Radwaniah , western south of Baghdad to study the effect of spraying two types of organic fertilizers , Alexin [0 (control) , 1.25 g/L (Alx1) and 2.5 g/L (Alx2)] and Tronver [0 (control) , 1.5 ml/L (Tro1) and 3 ml / L (Tro2) ] using four verities of potatoes Arizona , Riviera , Ambition and Lusa class Elite . Potato tubers were planted on 2-Feb-2013 used application N,P,K 120 : 60 : 200 kg / ha . Plants were spread at 45 and 65 days after planting . Split Plot Design with three replications was used. Results showed that Ambition was superior in number of stems per plant (4.60 stem / plant) and greatest number of marketable tubers (7.05 tuber / plant) and highest average tuber weight (107.87 g/tuber) and greatest of yield per plant (788.16 g) and marketable yield (40.69 ton/ha) . Fertilizer Tro2 gave highest in all vegetable growth and yield characteristics. Treatment Ambition with Tro2 was superior in most yield characteristics , its gave greatest number of marketable tubers (8.47 tuber / plant) , highest yield per plant (947 g / plant) and greatest marketable yield (50.07 ton / ha) , while treatment Lusa with Tro2 gave greatest of average tuber weight (112.43 g / tuber). The suggestion could be made that spraying of organic fertilizer Tronver in concentration 3 ml/L , 45 and 65 after planting resulted in highest yield per plant and marketable yield and produce healthy crop contain small amount of pollution chemical. | ||
