Abstract
Abstract Sweet basil (Ocimum basilicum L.) is susceptible to drought stress. In the commercial production of basil, biostimulant application has potential to enhance biomass production and promote the biosynthesis of secondary metabolites under drought stress. The current experimentation focused on assessing the effectiveness of selected biostimulants applied as seed priming materials on growth, herbage yield, and physio-biochemical composition of sweet basil exposed to drought stress. The seeds of sweet basil were primed with six agents (hydropriming, silicon (Si), salicylic acid (SA), gibberellic acid (GA), methyl jasmonate (MeJA), and chitosan (CHI)) and non-primed seeds were used as the control. Plants were subjected to three levels of soil water exposure (50, 75, and 100% field capacity (FC)). Seeds primed with GA and MeJA outperformed the non-primed control in all investigated parameters by increasing germination parameters, growth, herbage yield, and biochemical properties. An increase of 10–24 and 35–66% in height and leaf area of plant, respectively, was observed from MeJA-treated plants than the non-primed control plants, while GA-priming treatment enhanced leaf number per plant, aboveground biomass, herbage yield, irrigation water productivity, leaf relative water content, free proline content, net photosynthetic rate, stomatal conductance, total phenolic content, and total flavonoid content by 11–47%, 15–23%, 16–47%, 21–50%, 6–30%, 90–180%, 19–55%, 26–50%, 25–35%, and 46–67%, respectively, regardless of soil water contents. Seed priming with GA and MeJA could be an effective strategy for enhancing the performance of sweet basil plants grown either in well-watered or water-stressed conditions.
