To study the influence of different amount of nitrogen and amino acid on maize species, a factorial experiment was randomly performed in karaj institute of scion and seed researches in 2008, 2009 and 2010. Nitrogen in three levels of 0,115, and 230 kg per ha, amino acid sprinkling in three levels of 0,4,and 5 lit per ha and the species in three groups from two serotinal sorts of ksc 700 and ksc 704 and a rapidly- growing sort of ksc 500 were contemplated. the results showed that in the process of changes to leaf area, the most index, related to seronital ksc 704. and ksc 700 was the next the LAI of rapidly- growing Ksc 500 was Less than the other two seronitals. The LAI on all sorts got very high by increasing fertilizers of nitrogen (230kg) per ha and 5 lit of amino acid- the most CGR in the seronitals was for KSC 704 and Ksc 700 was the next. And the growth rapidity of KSC 500 was less than the seronitals. RGR in the seronitals was for Ksc 704, and Ksc 700 and Ksc 500 were the next. The results showed that coming to the lowest rate of RGR in KSC 704 and KSC 700 was later. This reality shows lasting of grain increase and getting late at the lowest point RGR of N1 230kg per ha and 5 lit amino acid in all three sorts shows this reality. Changes of TDW on the studied species show that during analyzing, growth rate was increasing in start. The most amount of TDW on shrub was for KSC 704 and KSC 700 and KSC 500 were the next. All three sorts on 230kg N1 and 5 lit of amino acid had the most TDW. Compared with the others. The change process of this experiment showed that the most NAR was for KSC 704 and KSC 700 and KSC 500 were the next. All the three sorts come to the lowest point as coming the time of physiological assimilation rate.
