Özet
Aims: Rice is one of the most applied irrigation waters applied plant amongcultivated plants since it is grown in water or in saturated soil conditionsin a significant portion of the growing season. This study was aimed todetermine the effects of rice grown on water use, development, yield andsome yield parameters using of both separately and jointly water retentionbarriers and subsurface drip irrigation methods in Enez, Edirne, Turkey in2017.Methods and Results: Four different treatments were applied: ponding((control(C)), subsurface drip irrigation system (SDI), ponding + waterretention barrier (C+WRB) and SDI+WRB in this study. Subsurface dripirrigation laterals were placed 10 cm deep from the soil surface and theWRB was placed at 30 cm deep. Plants were irrigated with a constantwater height of 10-15 cm on the soil in C and C+WRB treatments, 20% ±5% of the available water retention capacity is consumed withoutexposure to water stress in SDI and SDI+WRB treatments, the field capacityis completed. WRB and SDI applications significantly affected the irrigationwater amount, grain yield and yield components of rice. The yield andirrigation water amount according to the treatments varied between 321-715 kg da-1 and 751-2444 mm, respectively.Conclusions: In comparison to the control treatment, water saving wasachieved by 27%, 50%, 69% in C+WRB, SDI and SDI + WRB treatments,respectively. Despite this, when marketable yield values are analysedaccording to the control treatment, it has increased by 10.8% in C+WRB,and decreased by 48.8% and 40.7% in SDI and SDI + WRB treatments. Thewater retention barriers and subsurface drip irrigation practices used inthe study have been shown to reduce the use of irrigation water in riceproduction.Significance and Impact of the Study: It can be said that these methodshave the potential to be used especially in arid and semi-arid regionswhere water is limited or inadequate.
