This  experiment was carried out in a plastic house (500 m$^{2}$) at the vegetables farm of a local distinguished farmer / Zakho, Iraqi Kurdistan Region, during the growing season of  (2014--2015), the experiment was arranged as factorial experiment within split split"=plot and laid out by Factorial Randomised Complete Block Design (RCBD). Thus, the experiment consisted of three factors; the first factor was three planting dates, the second factor was Azotobacter and the third factor was three okra cultivars. The main plot was represented by three dates and subplot represented by three okra cultivars and the sub"=subplot was represented by Azotobacter. Therefore, the trial encompassed of 18 treatments (3 $\times$ 2 $\times$ 3), each treatment was replicated three times and the representative of each replicate was three lines, each line (2.4*\mbox{0.8\,m}) of 8 plants, with \mbox{30\,cm} intra space between plants. The number of experimental units was 54 units and the (SAS, 2007) programme was used for the purpose of results analysis. Means of Comparison was done by using Duncan's multiple range tests at \mbox{5\,\%} level. to investigate the effect of the biofertiliser (Azotobacter) and planting date on the yield quantity of three okra cultivars (\textit{Abelmoschus esculentus} L.) (Sultani, Clemson Spineless and Chervil Albaraa) under protective conditions. The main results are summarised as follows: The planting date significantly enhanced the quantitative characters of okra with the superiority for all planting date. The biofertiliser (Azotobacter) significantly enhanced fruit quantitative characters of okra (number of fruits.plant$^{-1}$ \mbox{18.87\,\%} , fruit weight \mbox{9.36\,\%}, early yield \mbox{11.11\,\%}, yield.plant$^{-1}$ \mbox{23.95\,\%} and yield per area 24.2 m$^{2}$), The cultivar factor significantly  improved the yield characters and the Sultani cultivar was the best among the three cultivars. }
