Abstract
A field trial to determine comparing of yield and yield components of hybrid rice (GRH1) in different application of nitrogen fertilizer, comprising of 2 treatments, nitrogen fertilizer at 100, 200 and 300 kg/ha was main plot and spilt application at 3 levels T1=(1/2basal-1/2mid tillering), T2=(1/3basal-1/3mid tillering-1/3panicle initation) and T3=(1/4basal-1/4 mid tillering-1/4panicle initation-1/4 flowering) as sub plot. Using randomized complete block design (RCBD) with 3 replications in rice research institute of Iran-departy of mazandaran (amol) in 2006 cropping season. The results showed that yield and yield components increased significantly with nitrogen fertilizer. Interesting in comparison to 100 and 200 kg/ha level application of higher N-fertilizer 300 kg/ha showed a positive respond to application of high nitrogen on hybrid cultivar. Effect of different split application N-fertilizer was significantly on parameter of above. Study interaction effect of treatments revealed that all the yield and yield parameters increased significantly with an application of 300 kg/ha N-fertilizer at 4 stages.

Study interaction effect of treatments revealed that all the yield and yield parameters increased significantly with an application of 300 kg/ha N-fertilizer at 4 stages. Nitrogen fertilizer is a major essential plant nutrient and key input for in increasing crop yield (Dastan et al, 2012). Time of nitrogen application acts the important role in increasing rice production. Panicles with allow percentage of sterile flowers permit the application of higher doses of nitrogen and produce better yield (yoshida, 1981). Grain yield and dry matter increased when application of higher dose of nitrogen fertilizer increased (Zhoung & Huang, 2002).Rate and timing of N rate are critical for optimum rice grain yield. Nitrogen fertilization increased the number of stems and panicles per square www.ccsenet.org/ijb
