Pot experiment with 6 tea plant genotypes was conducted to investigate the genotypic difference in N efficiency at 4 N levels. The results showed that there were significant difference in increased biomass yield, increased new shoots, N uptake efficiency, N physiological utilization efficiency, N economic efficiency and N use efficiency among 6 tea plant genotypes. The difference of N uptake efficiency was the main fact that resulted in the N use efficiency among tea plant genotypes.
