Agricultural production faces critical challenges in arid regions due to global climate change and water scarcity. Exploring optimal nitrogen irrigation combinations is essential enhancing use efficiency crop yields. This study employs the logistic growth model analyze impact of varying treatments on summer maize southern Xinjiang. The goal identify an strategy enhance productivity, optimize use, ensure precise management. Field experiments included three levels (W1: 80% ETc, W2: 100% W3: 120% ETc) four rates (N0: 0 kg/ha, N1: 168 N2: 306.5 N3: 444.5 kg/ha). A model, incorporating effective accumulated temperature, plant height, leaf area index (LAI), quantified dynamics. Maximum (vmax) average (vavg) were derived, followed by regression analysis estimate theoretical maxima corresponding irrigation-nitrogen requirements. provided a good approximation for height occurred at 106% ETc 340 kg/hm² nitrogen, with temperature 319.30 °C. LAI peaked 105% 334 239.75 °C during rapid growth. Optimal water-nitrogen identified, highlighting threshold beyond which excess application becomes counterproductive. W2N2 combination was identified as optimal, achieving 3.04 kg/m3. These findings offer practical guidance optimizing agricultural practices regions.
