This experiment was carried out in the experimental field , Horticulture Department , College of Agriculture , University of Baghdad , Abu-Ghraib , during fall 2006 and spring 2007 seasons using Desiree cultivar potato seeds class (A) in fall season and class (Elite) in spring season. In this experiment the effect of potassium spray and companion ion on tuber content of N , P and K and quality characteristics of potato tubers were tested. Three potassium fertilizers (K2SO4 , KNO3 and KCl) at three concentration (0 (control) , recommended 5 g K2SO4 / l, 5.80 g/l KNO3 and 4.28 g/l KCl, 1.5 times of the recommended concentration were used where 5 g K2SO4 / l was used as the recommended concentration. Solution of above mentioned salts was foliar applied twice , first 45 days (vegetative growth stage) and second 65 days (tuber bulking stage) after planting. Randomized Complete Block Design was adopted with three replicates. Least significant differences (L.S.D) at 5% probability was used to compare the means.
In fall 2006, potassium nitrate treatment at recommended concentration resulted in a highest content of N and K in tubers (1.24% , 2.25% respectively) compared to the control (0.86% , 1.65% respectively) . Potassium sulfate treatment at recommended concentration increased P% in tubers (0.46%) as compared with spraying potassium chloride 6.42 g/L which reached lowest P percentage (0.39%) . In spring 2007, S1 treatment significantly increased N content in tubers (1.24%) as compared with the control (0.91%) while spraying potassium chloride at recommended concentration resulted in highest K% in tubers (3.14%) as compared with the control (1.89%) . In fall 2006 , recommended 5 g K2SO4 treatment had highest percentage of dry weight , starch and specific density (16.51% , 10.75% and 1.062 g / cm3 respectively) compared to the control treatment (14.38% , 8.82% and 1.052 g / cm3 respectively) . In spring 2007 , recommended 5.8 g KNO3 / L treatment resulted in highest percentage of dry weight , starch and specific density (21.05% , 14.76% and 1.084 g / cm3 respectively) as compared with the control treatment (18.75% , 12.72% and 1.073 g/cm3 respectively).

This study was conducted in the field and cold storage unit, Department of Horticulture, College of Agriculture, University of Baghdad, during Autumn 2004 and spring 2005, two sizes (20-35) mm and (40-55) mm were used, the types of nutrient solution (grow more, grow plus, king life) were sprayed twice, the first after 45 days from planting and the second after 21 days from the first sprays.
After the harvest, curing was done and the potatoes tubers were kept in bags with 5 kgs for the experimental unit with 3 replicate, CRD were used. All the treatments were stored at 4 + 2 o C for 3 months. Reconditioning were used for the potatoes taken from the cold store.
The experimental results shows that no significant differences due to the seed sizes in the percentage of weight loss in the first season, while the smaller seed size enhanced the weight loss up to 4.88% as compared with the large tuber seeds which reduced it to 3.99 %.
Spraying with grow more increased the percentage of weight loss up to 4.42% as compared with spraying with grow plus which reduced this percentage to 3.66% for the first season. In the second season, spraying with king life increased this percentage up to 5.97% as compared with spraying with grow more which reduced this percentage to 3.41% at the end of store period.
There is no significant differences due to tuber seed size and type of nutrient solutions used in this study on the percentage of decay.
There is no significant differences due to the tuber sizes used in this study in the number of sprouted eyes in the first season. The small size tubers increased this percentage up to 61.1% in the second season as compared with large size tuber which reduced this percentage to 57.1 %.
The control treatment significantly increased the percentage of sprouted eyes up to 46.9 % as compared with the treatment with grow plus while reduced this percentage to 37.7 % in the first season, while in the second season treatment with grow more increased the percentage up to 69.2 % as compared with control which cases a reduction of this percentage to 50.7 %.
