ABSTRACT Irrigation water management is key to promoting resilient crop production amidst the increasing effects of climate change. Super absorbent polymer (SAP) an innovative technology for conserving irrigation within arid and semi‐arid lands (ASALs). AquaCrop, a productivity model, has been used management. This study aimed model response cowpea various SAP levels under greenhouse conditions via AquaCrop. The experiments included five application rates [0% (control), 0.05%, 0.1%, 0.15% 0.2% weight soil substrate] [full (FI), 80%, 70%, 60% 30% FI]. AquaCrop simulations matched observed values with normalized root mean square error less than 16%. simulated yield biomass full 0% were 5.1 11.0 t/ha, respectively, whereas 5.3 10.8 respectively. Treatments showed increased yield, biomass, (WP ET ) harvest index (HI) stress up 137%, 17%, 10% 117%, Thus, can improve production, suitable improving ASALs where scarce.

Maize is vital for global and Chinese food security. Yet, in Henan Province, a key maize-growing region China, water scarcity, uneven rainfall, inefficient irrigation fertilization limit its yield quality. This study combines two-year field experiment (2023–2024) with the DSSAT model to optimize typical hydrological years (wet, normal, dry). After calibration validation data, showed strong performance. Results indicate that optimal timing volume vary years: no needed wet years, one 30 mm at tasseling (VT) stage normal three irrigations (total 90 mm) emergence (VE), jointing (VT), grain filling (R2) stages dry years. The nitrogen fertilizer 240 kg·ha−1 water-rich 180 These optimized schemes can achieve 98–100% of maximum potential maize yields across offering practical insights enhancing agricultural nutrient management central support sustainable development reduce environmental impacts.

Water conservation is critical for global maize production, particularly in arid regions where water scarcity, exacerbated by climate change, threatens conventional irrigation sustainability. Optimizing strategies to reconcile productivity and yield remains a key scientific challenge water-limited agriculture. This four-year study (2018–2021) evaluated integrated management that combined frequency volume adjustments. A field experiment compared three strategies: high-frequency limited (HL: 2400 m3·hm−2), low-frequency (LC: (HC: 4800 m3·hm−2). The mean showed HL (10,793.78 kg·hm−2) had non-significant 18.2% numerical advantage over LC (9,129.11 kg·hm−2, p > 0.05). WUE reached 3.63 kg·m−3, representing an 18.6% increase (3.06 kg·m−3; Physiological parameters (plant height + 2.6%, leaf area 9.9%, SPAD 1.5%) marginal improvements HL, yet lacked both statistical significance (p 0.05) strong correlation. Multi-year analyses confirmed no statistically distinguishable differences between 0.05), demonstrating adjustments alone cannot reliably enhance drought resilience. These findings caution against advocating as superior practice, given the equivalence despite savings, gap HC. Future research must establish causality through models integrating real-time soil–crop–climate feedback prior recommending altered regimes.
