The present study was conducted to investigate the effects of different nitrogen doses on yield and nutrient uptake of rocket plant. The study has been carried out with three repetitions according to the experimental pattern of randomized plots in the plastic pots with the capacity of 3 kg under the greenhouse conditions. Nitrogen doses; 0 mg N kg-1, 50 mg N kg-1, 100 mg N kg-1, 150 mg N kg-1, 200 mg N kg-1and were applied as CaNO3.4H2O form. The rocket plant was harvested after 60 days of sowing and various traits like; shoot dry weight, macro- and micro-elements concentrations were determined. The results of the study have shown that the highest shoot dry weight was determined in 200 mg N kg1 application with 4.45 g pot-1. In addition, the highest N concentration (5.80 % N) wa sobserved in 200 mg N kg1 application, P concentration in 50 mg N kg-1application (0.34% P), K concentration in 100 mg N kg-1 application (7.01% K), Mg and Ca concentrations in 150 mg N kg-1 application (0.92% Mg, 1.35% Ca) were determined. Considering all treatments together, it was observed that increasing nitrogen doses increased yieldand macro and microelements concentrations of rocket plant.
