| Abstract | ||||
| Nitrogen fertilization plays an important roles for improving corn yield but it was easily lost after addition of N-fertilizers. This study was conducted during the season of 2015 for comparing five slow release N fertilizers namely, urea formaldehyde (UF), sulfur coated urea (UFS), sulfur& inhibitors coated urea (UFSIN). Cement coated urea (U Cement) and cement & inhibitors coated urea (U Cement in) and tow adding rates (recommended and 1.5 recommended) by soil application under a complete randomize design, with three replicates for each treatment. The results indicated that the best values of fresh and dry weight of shoot yield and flag leaf of maize (g) as well as plant height (cm), ear weights (g), 100-seed weight (g), protein of grain (%) and grain yield (g)of maize were at(UFSIN) treatment . Also, the values of nitrogen, phosphorus, potassium, contents in shoot and flag leaf of maize were evaluated under the effect of different types of coated urea. | ||||
