“…The WSDM values in the first season on the day 97 after planting were found to be higher in the treatments where 50% irrigation deficit was applied and FPRD75 treatments than the other treatments. Dasgan et al (2013) reported that WSDM values ranged between 3.62 -4.12% in cucumber plants grown under the partial root drying (PRD) technique. Ali et al (2020) reported that as the water deficit increases in cucumber plants grown through different irrigation levels and different doses of biofuel, the rate of WSDM increases in the fruit.…”

This study aimed to examine the effects of varying levels of deficit irrigation applied through partial root drying (PRD) and conventional deficit irrigation on some parameters of cucumber plant such as fresh and dried biomass, plant stem diameter, number of leaf, fruit length, fruit diameter, fruit weight, water soluble dry matter (WSDM). Seven irrigation treatments (DI75, APRD75, FPRD75, DI50, APRD50, FPRD50) were examined together with the control treatment (FULL). The irrigation water of the treatments DI75, APRD75 and FPRD75 are 25% less than the FULL treatment. The irrigation water of the DI50, APRD50 and FPRD50 treatments is 50% less than the FULL treatment. DI75 and DI50 are traditional deficit irrigation applications in which both sides of the plant root zone are wetted. In APRD75 and APRD50 treatments, one half of the plant root zone is wetted and the other half is left dry and the wet/dry parts are switched in each irrigation application. In FPRD75 and FPRD50 treatments, one half of the plant root zone is wetted and the other half is left dry for a fixed period during the entire season. It has been revealed that 25% and 50% water deficit levels affect the amount of biomass as a result of the application of conventional deficit irrigation and partial root drying (PRD) techniques when compared to the FULL treatment. However, it has been found that the parameters such as plant stem diameter, fruit length, fruit diameter, fruit weight and WSDM are not affected. When the results obtained in the research are evaluated; it has been observed that water application techniques (DI, APRD, FPRD) have a significant effect on both plant development and yield when the same amount of water is given. As irrigation water constraint increases, the yield has been found to decrease. However, the decrease in the amount of irrigation water and the decrease in yield have not been the same. Research aiming to save irrigation water is increasingly important, especially in arid and semi-arid regions where water is scarce and expensive. In this regard, the fact that the decrease in yield remains smaller than the rate of decrease in irrigation water can be seen as an advantage of PRD treatments.

Water availability has been a major constraint in crop production technology across the globe. The agricultural sector has been the largest consumer of fresh water for ages and accounts for about two‐thirds of the total fresh water used for human consumption. In the scenario of rapid population growth, the share of fresh water allocated to agriculture would get reduced to a great extent. Therefore, there is the ever‐increasing need to use the available water efficiently and precisely. It is a high priority to evolve new irrigation methods so that water use efficiency (WUE) can be maximized through optimum management of available irrigation water. Deficit irrigation (DI) is an optimization strategy that requires crops to intentionally endure a certain level of water deficit. This sometimes leads to a decrease in yield, however, with a significant increase in WUE. Partial root zone drying (PRD) is a modified version of DI, which has been practiced to improve WUE by controlling drought stress. In this method of irrigation, the spatial separation of dry and wet roots is maintained during the entire cropping season. The water stress developed in one part of the root zone generates chemical signals in the form of abscisic acid, which leads to partial closure of stomatal opening. Stomatal closure reduces the rate of transpiration, which in turn increases WUE. This paper is an effort to briefly discuss the concept of PRD and to review some important work carried out across the world.
