An experiment was conducted in vegetable crops farm of plant production department in Technical Agricultural College /Mosul/Iraq during spring season 2013 to study the effect of using organic fertilizers (Local poultry manure by two methods scattered and irrigation with fertilizer solution ) and dry bread yeast irrigated near the plants roots by three concentrations ( 0, 4 and 8 g L-1 ) The study included nine different treatments carried out in the Randomized Complete block design with three replications. The results showed that the addition of poultry manure as irrigation near the plants roots has led to a significant increase in plant height , number of stems per plant , leaf area , fresh and dry weight of plant which reached (33.77 cm and 3.08 stem and 2686 cm2 and 190.44 gr. and 38.40 gr.) respectively, superior on adding fertilizer by prose and control treatment . The addition of bread yeast near the plants roots , by two concentration 4 and 8 g L-1 led to a significant increase in the number of stems and leaf area and fresh and dry weight of the plant compared with the control treatment. And also it found that organic fertilization as irrigation has led to a significant increase in the number of tubers (7.26) , the average weight of tuber (59.15 g) , plant yield (453.8 g) , total yield (18.152 Ton. H ) and marketable yield (14.528 Ton. H-1 ) compared by adding fertilizer by scattered and control treatment .Also the results showed that the treatment of yeast concentration of 8 g led to a significant increase in the number of tubers (7.09) , the average weight of tuber (55.39 g) , plant yield (439.7 g) , total yield of tubers (17.588 Ton. H-1) and marketable yield (13.728 Ton. H-1) superior on 4 g L-1 and control treatment . The interaction between the organic fertilizer and yeast significantly affect most vegetative growth and yield characters and the interaction between organic fertilization by irrigation and yeast by 4 and 8 g
