Considering the critical challenges in food security, environmental quality improvement, and societal well-being, this study investigates the effects of zeolite and wood vinegar on the biochemical characteristics of camelina (Camelina sativa L.) under water deficit conditions. The aim of this research is to find solutions for enhancing the sustainability of food production under water scarcity using zeolite and wood vinegar as two effective factors in improving the growth and quality ofcamelina.
Four irrigation levels (optimal irrigation, mild, moderate, and severe water deficit) were considered as the main plots, two zeolite levels (zero and eight tons per hectare) and four wood vinegar levels (zero, 5000, 10000, and 15000 ppm) as subplots. The experiment was conducted as a factorial split-plot design in a randomized complete block design with three replications.
Based on the results of this study, irrigation regimes, zeolite application, and wood vinegar foliar spraying had significant effects on the physiological and biochemical traits of camelina plants. Generally, water stress conditions led to a considerable decrease in both fresh and dry weights of aerial parts of the plant. Additionally, grain yield and photosynthetic indices (chlorophyll a and b, total chlorophyll, and carotenoid) noticeably decreased during water stress, while water stress led to an increase in anthocyanin and flavonoid contents in the leaves. Under favorable irrigation conditions, zeolite application and absence of wood vinegar foliar spraying are recommended.
The application of zeolite and wood vinegar foliar spray can be used as a suitable strategy to increase plant resistance to water deficit stress.
