| Abstract | ||
| A field experiment was conducted at the field of College of Agriculture – Baghdad University (Abo-Ghraib) at spring season 2012 to investigate the influence of potassium fertilizer . Foliar application with potassium and organic extract on growth and yield of potato . The potassium fertilizer was applied at zero , 200 , 400 Kg K.ha-1 as potassium sulfate. Foliar application of potassium zero and 5000 mg.L-1 any spray with organic extract zero and 10 ml.litter-1 . The results of this study were : Application of potassium fertilizer , spray with potassium and organic extract give significantly increased in dry weight of shoot , yield weight and number of tubers and starch percentage in tubers. That were 6243.33 Kg.ha-1 , 36.07 Ton.ha-1 , 6.45 tuber . plant-1 , 140.33 gm.tubers-1 and 12.41% respectively in M10 F5000K400 treatment. | ||
