The aim of this study is to compare two methods of fertilizing: surface spray (conventional method) and fertilizer drilling method that was laid out on both sides of the plant row. The fertilizer was in source of urea and its values included, 90 kg of pure nitrogen per hectare by broadcosting as the control method and values of 30, 60 and 90 kg net N/ha by fertilizer drilling method . Fertilizer drilling method was laid out on both sides of the stack as top dressing and the plant was given additional amount of 90 kg/ha N at planting equally well in all treatments. The results of two years of implementation showed that fertilizing method had no significantly difference at 1% probability on plant height, ear height and cob percent but at 5% probability level on the net yield (yield with 14% humidity) and 1000 grain weight had significant effects. The effect of two methods of fertilizing on the amount of leaf nitrogen at 1% probability level by Duncan test was significant. In this study it was found that nitrogen fertilizer drilling was better than broadcost application and increased yield of corn and nitrogen content of corn leaf.
