Drip irrigation is gaining increased interest in the production of soybeans. The changing climate causes an increased demand for water sources of good quality. Consequently, the drip irrigation method should be adapted for the rational use of limited water supplies. Introducing deficit irrigation instead of traditional watering rates is imposed as a potential solution to achieve this goal. Therefore, the research examines the possibility of deficit irrigation in soybean production. The experiment was conducted in field conditions during 2022-2023, in the Vojvodina region, the northern part of Serbia, at the experimental field in Bački Petrovac, the Institute of Field and Vegetable Crops, Novi Sad. The irrigation was scheduled using the water balance method. The irrigation rate was 30 mm in the vegetative and 40 mm in the reproductive stages. Three treatments were investigated: full irrigation of soybean (F), regulated deficit irrigation (RDI) with 20% less irrigation rates in the veget...ative stages, and sustained deficit irrigation (SDI) with 20% less irrigation rates through the whole season. The rainfed treatment was also included. No significant yield decrease was found between F and RDI, while the yield reduction was the highest on SDI. The lowest yield was on rainfed treatment. Irrigation and evapotranspiration water use efficiency were similar on F and SDI, while lower values were found on SDI. The yield response factor is below 1, indicating that the soybean is tolerant to water deficit. The average value in the dry year is about 0.68 and in the humid year 0.74 without major variations between F and RDI. Lower values were found on SDI which corresponds to the achieved yields. Based on the data on yield and water use efficiency, it can be concluded that RDI can be recommended in soybean production in climatic conditions of the Vojvodina region.
