Green asparagus (Asparagus officinalis L.) is a widely grown and consumed crop which
provides high-level nutritional interest. In recent years, the decline syndrome in asparagus plantations
has been rapidly augmenting. This syndrome causes the early death of whole plants, also negatively
affecting the new replanting. Decline causes notable economic losses in the sector. The objective of
this work was to verify the effect of different treatments against asparagus decline syndrome on the
physiological parameters and nutritional quality of the spears. To meet the objective, four different
treatments were applied to asparagus plots strongly affected by decline syndrome: (T1) untreated
control soil, (T2) biofumigation with Brassica pellets, (T3) biofumigation with chicken manure pellets,
and (T4) disinfestation of the soil with Dazomet. The cumulative yield and physiological and quality
parameters of green asparagus spears were studied. Thus, malondialdehyde (MDA), photosynthetic
pigments, glutathione (GSH), ascorbate (AsA), total phenols, flavonoids, anthocyanin, antioxidant
test, mineral nutrients, and the amino acid profile were measured on asparagus spears. The results
showed that the Brassica pellets and Dazomet treatments were the most effective against the damage
caused by the decline syndrome. However, it would be necessary to monitor the evolution in the
following years.
