Abstract

This study was conducted to enhance plant resilience against drought stress, a major threat to agricultural production, by utilizing an eco-friendly application derived from agricultural waste. We investigated the protective effect of a smoke solution, derived from poppy harvest residues, on the biometric and biochemical parameters of two forage pea (Pisum sativum spp. arvense L.) varieties (GAP Pembesi and Özkaynak). Seeds were primed with 1% and 10% smoke solutions and grown under three distinct conditions: normal irrigation (control), moderate drought, and severe drought. Parameters including biometric traits, chlorophyll pigments, secondary metabolites, and antioxidant enzyme activities were analyzed. The smoke solution mitigated drought effects and enhanced antioxidant enzyme activities, both of which were statistically significant. While drought stress negatively impacted all measured parameters, the application of smoke solutions significantly mitigated these adverse effects, even promoting fresh and dry weight under control conditions. The response was dose-dependent; under severe drought, the 1% solution was more effective on leaf relative water content (LRWC), whereas the 10% solution had a greater impact on chlorophyll pigments and malondialdehyde (MDA). Both solution doses triggered the plant’s defense system, increasing levels of anthocyanins, superoxide dismutase (SOD), catalase (CAT), and other secondary metabolites. In conclusion, this research demonstrates that recycling agricultural waste into smoke solutions is a viable and innovative strategy to alleviate environmental challenges such as drought. These findings highlight the potential of poppy-smoke solutions as regulators of plant biochemical content, contributing to both sustainable agriculture and climate adaptation strategies.
