Management of abiotic stress in horticultural crops

Horticultural crops are exposed to multiple abiotic stresses because of ongoing climate change. Abiotic stresses such as drought, extreme temperatures, salinity, and nutrient deficiencies are causing increasing losses in terms of yield and product quality.

The horticultural sector is therefore searching for innovative and sustainable agronomic tools to enhance crop tolerance towards these unfavorable conditions. In a recent review published in Agronomy, 'Biostimulants Application in Horticultural Crops under Abiotic Stress Conditions', Bulgari and colleagues discussed the main pieces of evidence of the use of biostimulants to manage abiotic stresses in vegetable crops.

The intent of this editorial was to focus the attention on aspects related to the stress development in plants (i.e., timing and occurrence of multiple stress factors), in combination with the application of biostimulants. The large number of factors potentially involved in the enhancement of crop tolerance toward stress calls for an intensification of research activities, especially when conducted in field conditions and with well-defined protocols. This must be seen as a mandatory task for a successful implementation of biostimulant products among the available agronomic tools for the management of abiotic stresses in horticultural crops.
