Abstract

Drought stress reduces growth, yield, and photosynthetic efficiency in pea plants, limiting nutrient uptake and requiring mitigation strategies. Salicylic acid plays a key role in plant development, and pea (Pisum sativum L.) ranks fourth in global production. A pot experiment was conducted to evaluate the effect of salicylic acid on two pea cultivars viz: Super Classic and Madarna, under water stress conditions at the Botanical Garden Research Area, University of Agriculture Faisalabad PARS, in 2021. Salicylic acid was applied as a foliar spray at concentrations of 0 (control), 50 ppm, 100 ppm, and 150 ppm. Drought stress was imposed at two levels: 100% field capacity (FC) and 75% FC. The experiment was conducted in completely randomized design (CRD) with a factorial arrangement and each treatment was replicated three times. The analysis revealed that drought intervals significantly affected various growth indicators, including fresh and dry weights of both shoots and roots, their lengths, physiological pigments such as chlorophyll and carotenoids, ionic contents of Na + , K + , and Ca2 + , and the overall yield. Notably, the application of 150 ppm salicylic acid effectively mitigated the effects of drought stress in pea plants. In conclusion, salicylic acid demonstrated beneficial effects against drought in pea plants by enhancing growth and yield while protecting photosynthetic pigments. Additionally, the Super Classic variety exhibited greater growth compared to Madarna when treated with salicylic acid at the 150 ppm concentration under drought stress.
