Abstract

Asparagus decline syndrome (ADS) poses a critical challenge to the productivity and quality of asparagus (Asparagus officinalis L.), threatening the sustainability of its cultivation. This study evaluated the impact of ADS over four years in Western Europe by comparing soils with and without a history of the syndrome. The results revealed a consistent reduction in yield, with losses of 36% in 2019 and 2020 and 23% in 2021 compared to the results for the control soils. ADS also increased the proportion of non-commercial spears, peaking at 52% in 2020. Key quality parameters were significantly affected by ADS, especially in the final year of the trial, with reductions observed in spear weight, diameter, firmness, and volume. On the other hand, °Brix values increased by 10% to 16%, while juiciness decreased by 10% to 28%, depending on the year, enhancing sweetness but compromising texture, and thereby, marketable quality. The findings highlight the detrimental effects of replanting asparagus in ADS-affected soils and the need for integrated management strategies to mitigate its impacts. This research contributes valuable insights into ADS dynamics, offering a foundation for developing agronomic solutions that enhance productivity and ensure the long-term viability of asparagus cultivation in affected regions.
