Abstract :

     In order to study of  different    effects  of  seed  rates  and nitrogen  levels  at  the  booting stage on  the   grain yield and yield components of N-81-18 line at the different conditions of  Mazandaran clime experiment as split- plot at the random complete Blocks design at the four replication at 2009 -2010 year at two regions of Gharakhyl and the Farim was executed in the Sari and Ghaemshahr agent. Main plot includes 3 levels of seed rates (200, 250, 300 kg/ha) and sub plot has been included 3 levels of nitrogen at the booting stage (0-17.5, 35 kg of nitrogen or o-37.5, 75 kg from urea resource). Results showed that bending moment at the Gharakhyl region (height from sea level is 14.7 meter) then pharim region (height from sea level is 725 meter) because of shortest internodes height, culm height, the number of internodes, weight of culm wet and spike weight was less. With excess of seed rate to 300 kg/ha, bending moment for the most low weight of culm wet and spiek had reduction and nitrogen levels at the booting stage had not signification effect on the bending moment. Grain yield at the Farim region was 20.22 % more than Gharakhyl reason of this was increase of the number tiller on plant, the number of spike at the grand unit, increase of 1000-grain weight and the number grain at the spike. Grain yield with a lot consumption of nitrogen at the booting stage than without consumption of nitrogen increased 10.8 %. However seed rates was not signification effect of grain yield but was received the most and less number of spike at the grand level unit respectively as 300 and 200 kg, seed /ha.
