Today, drought stress is one of the limiting factors for the development of green space. One of the solutions to reduce the effects of drought stress for plants is foliar spraying with potassium silicate. In order to investigate the reduction of the adverse effects of low irrigation with the application of potassium silicate on ligustrum vulgare L. in the research greenhouse of Ferdowsi University of Mashhad, a factorial experiment was conducted in the form of a completely randomized design in 4 replications in 1400-1401. Experiment in the form of pot cultivation in 3 levels of low irrigation (control (100% crop capacity), 50% crop capacity (SDI), 50% crop capacity with PRD technique and 3 levels of foliar spraying with potassium silicate (0, 2 and 4%) It was done in 4 repetitions. According to the results, the highest plant height related to the treatment of no drought stress and foliar spraying with 4% potassium silicate (68.5 cm) and the lowest plant height in the drought stress of 50 PRD and without foliar spraying (29 cm) ) was the highest antioxidant activity in the treatments of drought stress 50% + potassium silicate 2% foliar spraying (67%), also in PRD 50 and without potassium silicate foliar spraying (69%) and in potassium silicate foliar spraying 4% (72%) . total phenol was the highest in PRD 50 and 4% potassium silicate foliar treatments (11.16 mg/gfw). Total carbohydrates in 50% drought stress and 4% potassium silicate foliar treatments (0.93 mg/g fw) in plants and proline in treatments of drought stress PRD 50 and without foliar spraying of potassium silicate (4.06 mg/g fw) was higher than other treatments. The results showed that drought stress with 50% FC + PRD technique compared to drought stress with 50% Crop capacity has disturbed the optimal growth of the plant, but in combination with potassium silicate foliar application, the growth and survival of the plant improved. Based on the results of this experiment, in the irrigation treatment with 50% crop capacity, the condition of the plant improved with potassium silicate foliar application.
