Effect of Water Stress on Strawberry Yield and Yield Components using Magnetized Water

Searching for ways to reduce consumption and preserve water resources is of great importance. Using magnetized water may be effective in this regard. In this research, the effect of water stress using magnetized water on the yield and yield components of strawberry plants was investigated. The factorial experiment was conducted in the form of randomized complete block design with three replications in 2021 and 2022 in Neka Region. The main factor included the type of irrigation water (Non-Magnetized Water (W1) and Magnetized Water (W2)) and the secondary factor included the level of irrigation in three levels (100% FI: Flood irrigation =I1, 80%FI =I2, and 60%FI =I3). The results showed that the effect of irrigation water type and irrigation level on the number of fruits per plant, length, diameter and weight of fruit, biomass, and plant yield and water productivity was significant (p< 1%). On average, by application of magnetized water, the number of fruits per plant, length, diameter and fruit weight, biomass, plant yield, and water productivity were increased by 15.1%, 16.6%, 18%, 20/2%, 23%, 16.8%, and 11.7%, respectively. By reducing the amount of irrigation water, the appearance characteristics of strawberry fruit and yield decreased, but the water productivity increased. The biggest decrease was related to the number of fruits per plant at the irrigation level of 60%, which decreased by 42.72% compared to the control treatment. In conclusion, use of magnetized water technology and deficit irrigation improved strawberry yield.
