Influence of hydrolyzed animal protein-based biostimulant on primary, soluble and volatile secondary metabolism of Genovese and Greek-type basil grown under salt stress

Basil is susceptible to stressful conditions, of which salinity a major problem in agriculture, causing significant yield losses. Biostimulants can be used as stress reducers and for sustainable agriculture. Genovese-type 'Marian' basil Greek-type 'Manos' were grown under 100 mM NaCl salt conditions treated with hydrolyzed animal protein-based biostimulant (as foliar fertilizer via nutrient solution). Greek was positively affected both treatments. The irrigated had positive effect on primary metabolites basil. Foliar application the resulted higher glucose ascorbic acid content (+23.8% +25.7%, respectively) compared treatment Phenolic increased biostimulant-treated cultivars ranged from +73.3% +628.9%, depending cultivar treatment. Volatile most by added solution 18.5% 111.5% Genovese than With results our study, we have laid foundation further studies internal quality herbs method more suitable production conditions.
