Comprehensive evaluation of the optimal rates of irrigation and potassium application for strawberry

Accurate and effective management of irrigation fertilization is essential for efficient greenhouse strawberry production. Here, the effects combined application water potassium on growth were evaluated by experimenting with 12 treatments, including four transpiration (ETC)-based levels (W1: 100% ETC, W2: 85% W3: 70% W4: 55% ETC) three according to target yield (K1: 369.5 kg/hm2, K2: 307.9 K3: 246.3 kg/hm2). Various indexes yield, fruit quality, fertilizer utilization efficiency, soil nutrient residues measured. Irrigation had significant Higher increased (Y), moderate single weight (SFW), efficiency (WUE), total soluble sugar (TSSC), sugar-acid ratio (SAR). While low-application protein content (SP), partial factor productivity (PFPK), reduce in effectively. A comprehensive system evaluating its benefits environment was developed. The FAHP CRITIC methods used calculate subjective objective each index, respectively. largest observed Y (0.200), soil-available (0.101). final determined using Game theory; highest (0.185), free amino acids (FAA) lowest (0.047). Grey relational analysis (GRA) evaluate optimal scheme accomplishing multiple objectives. response score strawberries exhibited a negative parabolic relationship, effect greater than application. There interaction between application, an amount 2053-2525 m3/hm2 rate 288.1-334.2 kg/hm2 promoting reducing residues. results this study provide new insights that could aid development sustainable approaches enhancing agricultural Keywords: strawberry, irrigation, potassium, FAHP, CRITIC, DOI: 10.25165/j.ijabe.20231602.7591 Citation: Yang X Q, Du R C, Zhang M Feng H W, Wang Z Z.
