| Abstract | ||
| A field experiment was conducted in the experimental field belongedto the agricultural extension in Al-Mhanawiya region north-west Babylon government who is followed to Babylon department of agriculture during the spring season 2014-2015, using randomized complete block design (RCBD), with three replication for sixteen treatment to get 48 experimental unit, dimension 3×3m as factorial experiment, to study the effect of different concentrations of potassium element (0 , 100 , 150 , 200) ppm as a foliar application as a first treatment, and different concentration of diluted sulfuric acid (0.100 ، 0.050 ، 0.025 ، 0.000) N added with irrigation water as a second treatment, The means compared by less significant difference (LSD) test and the level of probability 5%, to determine the effect of study factors in number of growth and yield characteristics of corn plants, showed that results of this study the foliar application of potassium fertilizer level (200 ppm) led to improve the traits growth and also characteristics of the yield and yield component as follows (number of grains per ear, 500 grain weigh, grains yield and the biological yield) and it increased with percentages of ( 5% , 4.7% , 10% , and 7.95% ) respectively about control treatment, while the effect of diluted sulfuric acid level (0.025 N) who added with irrigation water showed in the vegetative traitsgeneraly.In addition that interaction between (0.025 diluted sulfuric acid and 200 potassium ) was superior for number of characteristics (number of rows per ear , grains yield and harvest index) . | ||
