Abstract

This study was conducted in the field during the spring season of 2017 at the college of Agriculture (the alternative site of Anbar University / Abu Ghraib) Planted potatoes class (ARIZONA and RIVIERA)Rank elite On a furrows 5 m long and 75 cm wide, 25 cm wide and 10-12 cm deep. The trial land is randomly divided into three replicates , 42 experimental units will be designed according to the randomized complete block design (RCBD). The parameters of the study included seven treatments of the comparison and the nutrient spraying treatments, the NPK liquid fertilizer (36-12-12) , the paper solution (G-Power Ca) , fish extract (fish extract liquid ) Liquid NPK fertilizer (20-20-20) and marine herb extract (seaweed fe) with concentrations 2.5 mg/l-1 and treatments code (T1-T2-T3-T4-T5-T6-T7). The results showed a significant increase in the treatment T6 in the number of stems 3.93 stem plant-1 the that the While the T3 treatment showed a significant increase in the marketable yield 40.68 tons h-1 and protein content 1.81% . While the treatment of T2 was higher in N ratio of nitrogen 1.303% of leaves. While the treatment T5 showed a significant increase in the number of tubers per plant 10.23 tuber plant-1, and the nitrogen ratio was 1.376% in the tubers.
