Effect of water deficit imposing methods on yield and water productivity indices of Cucumber (Cucumis sativus L.) in Ahvaz region

In order to investigate the effect of irrigation deficit on cucumbers grown in greenhouse conditions, an experiment was conducted in a completely randomized block design with three irrigation levels of 100, 85 and 75% water requirement in two growing seasons during the years 2018 and 2019.Performance and quantitative and qualitative performance indicators were measured during the experiment. The results showed that in the first crop of treatments of 85 and 75 percent of water requirement, the amount of water consumption productivity decreased by 6.12 and 15.73 percent compared to the control treatment, respectively. Also in the second crop, the amount of water consumption in treatments of 85 and 75% of water requirement compared to the control treatment has decreased by 3.4 and 12.6%. Analysis of data related yield indices and plant growth indices showed that with decreasing water consumption, water productivity and performance are significantly reduced.
