Effects of Sewage Sludge Compost and Vermicompost on Wheat Yield and Vitality

This is the authors' abstract. We don't add key points for this paper.

This study investigates the effects of compost and vermicompost derived from sewage sludge and moulded pulp on wheat yield, nutrient uptake, photosynthetic activity, and drought resistance. Optimal weather conditions in March facilitated timely wheat sowing, contributing to ideal yields, while subsequent higher temperatures and rainfall influenced grain formation and weight. The experiment demonstrated that vermicompost significantly enhances plant physiological and yield parameters, including photosynthetic activity, chlorophyll content, and water use efficiency. Fertilized variants exhibited improved soil properties, leading to higher grain and straw yields compared to the control. Macronutrient uptake was notably higher in vermicompost-treated variants, with variant VI showing the highest values. Enhanced photosynthetic activity and drought resistance were observed in fertilized variants, attributed to better stomatal regulation and osmotic adjustment under stress conditions. The study underscores the role of vermicompost in promoting sustainable agriculture by improving nutrient availability, soil structure, and plant resilience. These findings suggest that compost and especially vermicompost applications can effectively enhance wheat productivity and resilience, offering a sustainable approach to improving crop performance under varying environmental conditions.
