Current study was carried out in Fadak farm, Najaf province during 2021 season to determine the effect of adding 60% of recommended level by manufactured company of traditional N.P.K fertilizer and spraying nano-boron on the chemical and qualitative content of Armenian cucumber in greenhouses. Randomized Complete Block Design (RCBD) was used to arrange the experiment with three replicates and two main factors. Different level of N.P.K including control treatment A0 (without adding fertilizer), adding the recommended level as one dose A1, divided the recommended level into two doses A2 and divided the recommended level into three doses A3 as well as spraying three concentrations of nano-boron (0, 5 and 10mg L-1) represented as B0, B1 and B2. Least Significant Difference (L.S.D) was used to compare means of treatments at 0.05 level of probability. Results showed that A3 treatments and 10mg L-1concentration of nano-boron were significantly exceeded in the percentage of nitrogen, phosphorous and potassium in leaves and fruits content of carbohydrates, nitrates and fibers. The interaction treatment A3 + 10mg L-1concentration of nano-boron was significantly exceeded in all studied traits.
