A factorial experiment was conducted in randomized block design in seed and
plant Improvement Institute, Karaj - Iran during 2008, 2009 and 2010, in order to investigate
The effect of different amounts of nitrogen and amino acids on maize varieties. Nitrogen was
considered in the three levels of 0, 115 and 230 kg ha, spraying amino acids was
considered in three levels of 0, 4 and 5 liters per hectare and also varieties were considered
in three levels of two varieties of long-term KSC700 and KSC704 and an unripe variety of
KSC500. The results showed that comparison of the interaction of nitrogen fertilizer, amino
acids and variety on the number of days and degree of growth days showed that Reducing
the consumption of fertilizer, the duration of phenological period and the degree of growth
of emergence of pollen and peak have increased. With increasing the joint consumption of
amino acids, complete inoculation period, dough and physiological maturity have increased.
All the features under investigation were more in KSC700 variety. KSC704 and KSC500
varieties were in rank order respectively.
