Abstract :
The large fluctuations of the final yield of greenhouse cucumber are of great importance in Iran due to its very large cultivated area, so that 76.47% of all greenhouses in the country are under cucumber cultivation. In order to investigate the effect of crop density and variety in the production of greenhouse cucumber (Cucumis sativus), a factorial experiment was conducted in the form of a basic design of randomized complete blocks in 3 replications during 2016 and 2017. Based on this, single-flowered, double-flowered, medium-flowered and multi-flowered cucumber cultivars were cultivated in different planting densities of 37, 42 and 47 cm. The results of the research showed that the highest production productivity was achieved in the planting density of 42 cm between the plants and the selection of multi-flowered cultivars with a maximum yield of 270 tons per hectare, and the lowest yield was obtained in single-flowered cultivars with a planting density of 37 cm. meter and numerical value of 197 tons per hectare was obtained. Therefore, the main reason for the decrease in cucumber yield in Tehran province was the selection of low-flowering cultivars with inappropriate planting density.
