In order to study the effects of nitrogen rates and nitroxin inoculation levels on quantitative traits of borage, a field experiment was conducted as split plots arrangement based on a randomized complete block design with three replications during growing season 2011-2012. Treatments consisted of four nitrogen rates (0, 50, 100 and 150 kg/ha) and three nitroxin amounts (0, 0.5 L/ha Seed inoculation and 0.5 L/ha as a foliar application) which were allocated to main plots and sub plots, respectively. Result indicated that the treatments had significant effects on plant height, stem height, number of leaves, number of flowers per plant, number of branches, the yield of inflorescence and total dry yield of borage. The highest plant was related 100 kg/ha nitrogen + seed inoculation and the lowest value was achieved control. There was a significant interaction between nitrogen and nitroxin due to most traits. The highest inflorescence yield (1168.11 kg/ha) and yield of the plant (9294.01 kg/ha) were achieved by using 100kg/ha nitrogen + seed inoculation, which was 50% higher than the control.
