| Iran's agricultural landscape confronts significant challenges from excessive groundwater extraction, leading to escalating salinity levels that threaten saffron yield. This study investigates the effectiveness of nano-sized cattle manure fertilizers in mitigating salinity stress in saffron cultivation. Nano-sized particles (mean diameter 45 ± 5 nm, >90% particles below 100 nm) were produced using ball milling and characterized through scanning electron microscopy and particle size distribution analysis. The experiment employed a randomized complete block design with three replications (n=36, α=0.05, power=0.85), testing four irrigation water salinity levels (freshwater, 1.75, 3.5, and 5 mS cm⁻¹) and three fertilizer treatments (nano-sized cattle manure, conventional cattle manure, and control) in field conditions at Torbat Heydarieh County, Iran during 2019-2020 growing seasons. Results indicate that higher irrigation water salinity reduces saffron yield by 39% while incorporating cattle manure fertilizers results in a 27% increase, and nano-fertilizer applications enhance yield by 51.8% (p<0.01). Furthermore, both treatments improve electrical conductivity thresholds by 18.5% and 43%, respectively, and significantly reduce soil bulk density by 23% and 31%, respectively (p < 0.01). The nano-sizing process reduced fertilizer half-life from 34 to 9 weeks, enabling more efficient nutrient availability [34]. Cost-benefit analysis indicates a 2.3-fold return on investment for nano-fertilizer application compared to conventional methods, despite higher initial costs. While long-term environmental impacts require further investigation, this study advocates for adopting nano-sized cattle manure fertilizers as a sustainable and economically viable approach to address the challenges posed by salinity in saffron cultivation, particularly in regions facing increasing groundwater salinity issues. | ||
