Abstract

Nitrogen is one of the most important elements required for grain production in different parts of the country. In order to investigate nitrogen consumption in planting three silage corn cultivar: medium Karaj KSC500, new serotinous KSC703 and local serotinous KSC704 were tested as factorial in the form of random blocks with three replications in the land located in Lamabad Village- Malard- Tehran. In this experiment, two factors have been considered the first one of which is factor (A) including three silage corn cultivars of local KSC704, KSC500 and KSC703 and factor (B) presenting different levels of nitrogen fertilizer at four treatments including: control (use of urea in accordance with local fields), spraying urea at one stage plus topdressing, spraying urea at two stages and the use of sulfur coated urea (granular) at the time of planting. The effect of nitrogen on plant height was significant at 1% level. Based on the comparison of the mean leaf length based on cultivar factor the maximum length of the leaf was 83.28 obtained by KSC 704 and there was no significant difference between KSC 703 and KSC 500. The results of variance analysis revealed that there was a significant difference between the cultivars at 1% level but the effect of nitrogen and the interaction between nitrogen and number of leaves was not significant.
