This experiment was carried out in greenhouse condition to evaluate the effect of foliar spray of methanol and combined bio-fertilizers (Azoto-barvar1 and phosphate- barvar2) on greenhouse cucumbers fruit yield (Negin and Nagin) in two planting periods of spring and autumn as a split-split plots in randomized complete block design with three replications. The bio-fertilizers were used as seed inoculation and plant injection (top – dressing). Methanol foliar application at four levels (0, 5, 15 and 25%) started in the 8-6 leaf growth stage and was repeated three times during 15 days once. Fruit harvest was performed at average size in all treatments. A product of each treatment measured separately and at the end of the planting season, the sum of all impressions for each plot was applied as a final yield of the plot. Analysis of variance and means comparison were performed by SAS9.2 software. The analysis of variance in both planting periods (spring and autumn cultivation) showed that the Negin and Nagin cultivars are not statistically different. Also, the effect of combined bio-fertilizers (Azoto-barvar1 and phosphate- barvar2) on cucumber fruit yield was not significant in both planting periods. But, in both planting periods (spring and autumn cultivation) the effect of methanol foliar spray was significant at p>1% probability and by increasing the percentage of methanol from 5% to 25% cucumber fruit yield increased with the bullish trend and significantly. The highest yield of cucumber fruit was obtained from 25% methanol foliar spray. The treatment of 5% methanol foliar spray increased cucumber fruit yield compared with the control significantly, too. The interaction effect of bio-fertilizer and methanol foliar spray was significant (at the level of 1%) in autumn planting that indicated the different reaction of C factors various levels within B factor levels.
