Physicochemical and Functional Value of Lettuce: Effect of Mulching Technique Used During Production on Postharvest Storage

Abstract

Lettuce is one of the most important vegetable crops cultivated worldwide. Mulch or mulching is used to protect the soil surface, create a physical barrier, and provide a more suitable environment for crops. The aim of our work was to evaluate the effect of different mulching techniques and test their effect on the morpho-physiological performance and nutritive value of Iceberg lettuce plants, and their changes during postharvest storage. Mulching soil treatments had a significant impact on biometric measurements such as yield, physicochemical values, and functional value in lettuce heads. Organic mulch had the best result, improving the bioactive compounds in lettuce.
