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.

Mulching significantly increases the crop yield and quality by positively affecting the physical features of the soil. The effect of multiple mulching treatments on soil temperature, yield, and nutrient composition of green asparagus grown in a plastic tunnel was assessed. Two mulch materials: transparent plastic film (PF) and rice husk (RH), were applied and compared with non-mulching treatment (CK). The soil temperatures at the soil surface and 10 cm below it were generally higher in the PF mulch than in the CK during the spring. PF mulch accelerated early spear emergence and growth, which led to harvesting 16 days earlier than in the CK. Under the PF mulch, the early yield of spears increased by 26.6% from January to the end of March, and the annual gross income by 14.8% because of the higher price resulting from the significantly higher marketable spear length and diameter; however, they were reduced in the RH mulch. Most nutrient compositions, such as soluble sugar, ascorbic acid, rutin, flavonoid content, and total antioxidant activity, were significantly increased in the PF mulch treatment. PF mulch might benefit green asparagus production during early spring because of its ability to promote early spear emergence and growth. Full article

Effect of Subsurface Drip Fertigation with Nitrogen on the Yield of Asparagus Grown for the Green Spears on a Light Soil in Central Poland

During the growing period of many agricultural and horticultural plants, the use of fertigation usually increases the yield; however, the response to this treatment may depend on the cultivar. The effect of subsurface drip fertigation with nitrogen on the yield of three asparagus (Asparagus officinalis) cultivars grown for green spears in light soil was studied. The multi-year (2011–2017) field experiment was carried out on sandy soil and was arranged in a split-plot design with four replications. The first factor was the method of fertilization with nitrogen: (1) control—spreading nitrogen fertilization without irrigation and (2) subsurface drip fertigation with nitrogen. The second factor was the genotype (a cultivar) of asparagus—the following cultivars were tested: Ramada, Rapsody and Ravel. Generally, subsurface drip fertigation with nitrogen increases the marketable yield of green spears and the number of spears produced by a single plant, as well single-spear weight. ‘Ramada’ achieved the best results with all yield parameters. A significant correlation coefficient between the sum of rainfall and irrigation rates and yield parameters of tested cultivars was also found. The studies showed a varied response of the tested asparagus cultivars to the fertigation treatment. Full article

The aim of this study was to verify the response of 13 American asparagus cultivars cultivated for green spear on surface postharvest drip irrigation. Irrigation, used to compensate for periodic deficiencies in precipitation, allows for high- and good-quality crops for many species. The field experiment was carried out in 2006–2008 on a very light sandy soil in central Europe (Poland). Irrigation treatments were applied using the tensiometer indications. Water requirements of asparagus were calculated on the base of reference evapotranspiration and crop coefficients. The following evaluations were made: Height, diameter, and number of summer stalks, as well marketable yield, weight, and number of consumption green spears. Drip irrigation applied for 2 years (2006–2007) in the postharvest period had a positive effect on all studied traits in both summer stalks and green spears in 2007–2008. A significant increase in the height, number, and diameter of summer stalks, as well an increase in the marketable yield, weight, and number of green spears was observed for most of the cultivars. In general, postharvest drip irrigation of asparagus cultivated in very light sandy soil significantly contributes to the increase in productivity of American cultivars of this species. Full article
