Evaluating the effect of a biostimulant on growth performance and productivity of Vitis vinifera 'Aglianico' through a multidisciplinary approach tracing functional traits in the continuum soil-plant-atmosphere

Grapevine is the most widely cultivated fruit crop in the world and Italy is one of the world's leading wine-producing countries whose vineyards are facing environmental constraints due to climate-change-driven rising temperatures, changes in precipitation frequency and occurrence of extreme events. In this scenario, the use of biostimulants to improve vines' capacity to cope with biotic and abiotic stressors is considered a promising practice in vineyards. Indeed, specific products can be a useful tool to improve the vineyard resource use efficiency, enhancing the tolerance to water scarcity and excess solar radiation. Moreover, by strengthening plant tissues and improving resistance to diseases, they can complement the utilization of chemicals in the pest control for a more sustainable crop management. In this study, we tested four different combinations of a biostimulant and conventional chemicals for pest control on ...
