Synergistic impact of nano-fertilisers and seed priming on sugar beet (Beta vulgaris L.) yield and quality traits

Enhancing sustainability in agriculture requires innovative practices that boost crop productivity while conserving natural resources. This two-season field study (2023–2025) in sandy soils of El Sadat City, Egypt, evaluated the combined effects of nano-fertilisers and seed priming on the growth and yield of sugar beet (<i>Beta vulgaris</i> L.).Five fertilisation regimes, ranging from 100% conventional to 100% nano-formulations, were tested under both primed and unprimed seed treatments. The results demonstrated that the integration of nano-fertilisers with seed priming significantly improved sugar yield (up to 36.1 t/ha), sucrose content (20.35%), and nitrogen use efficiency(55.1 kg sugar/kg N). Post-harvest soil analysis showed improved nutrient retention, indicating enhanced environmental performance. This approach supports climate-smart agriculture by optimising nutrient input, reducing losses, and improving soil sustainability. Our findings highlight the potential of nano-agronomic inputs to contribute to global food security under conditions of climate change.
