| Abstract | ||
| Field experiment was conducted to study the effect of KCl fertilizer on growth and yield of corn Zea mays L (Abu- Ghraib 106) was grown during the summer season of 2005 at two different locations in Sulaimani governorate. The first at Kanypanka and the second at Bazyan. KCl fertilizer was used with different rates (0, 75, 150, 225, 300 kg K+ha-1). Results indicated that the increasing of application of KCl fertilizer caused an increase in dry matter yield by an amount of 71.17% for Kanypanka location and 51.45% for Bazyan location. Grain yield was increased by the ratio of 30.17% and 55.45% for Kanypanka and Bazyan location respectively. The relative yield was 91.72 to 85.44 % for Kanypanka location and 97.00 to 65.83% for Bazyan location. The K-fertilizer response was increased from 8.27 to 41.56% at Kanypanka location while at Bazyan location was 3.00 to 34.25%. Fertilizer use efficiency ranged from 61.63 to 85.53% for Kanypanka location and from 26.60 to 54.83 % for Bazyan location | ||
