Abstract :
The amylase and protein percents may be influenced by elemental nitrogen and its segregation in paddy fields. With this regard, a field experiment was done to examining the quantity and segregation of nitrogen fertilizer effects on some seed quality traits of local Tarom variety. Experiment was done as factorial design based on RCBD with three replications during 2007-2008 in country’s rice research institute in Amol. Treatments were selected three levels of nitrogen (23, 46 and 69 kg/ha) as first factor and three nitrogen segregation which applied in different growth stage as second factor. The results showed that the rice seed's amylase content decreased with the increase of N using segregation procedure. The highest protein percent was obtained with the use of 69 kg/ha N and with the implementation of two segregation stages, the protein percent increased more than other treatments, and the best treatment combination was two segregations of nitrogen application. When the rate of nitrogen was increased, the yield of seed was increased too. Whatever has increased the number of segregation of nitrogen, the rate of yield also has increased.
