Effects of organic and inorganic fertilizers on growth, yield and quality of lettuce (Lactuca Sativa L.) in rooftop garden

Urban Farm DB summary

A pot experiment in a rooftop garden investigated the effects of organic and inorganic fertilizers on lettuce growth, yield, and antioxidant properties. Treatments with cowdung, alone or combined with vermicompost and biochar, increased plant height, leaf number, and shoot weight compared to control and inorganic fertilizer. Antioxidant compounds increased with organic fertilizers but decreased with inorganic fertilizers, suggesting organic fertilizers improve lettuce yield and quality in rooftop gardens.
