Effect of growing systems on yield and quality of lettuce (Lactuca sativa) under subtropical climatic condition

The study was carried out to indentify suitable growing system for higher yield of lettuce (Lactuca sativa L.) at ICAR-CISH, Lucknow during 2021-22. The experiment was conducted with two growing, aeroponic and geoponic systems. Five lettuce varieties were sown in portray by using mixture combination of coco peat, vermiculite, and perlite in a 3:1:1 ratio. After 30 days, plants were transplanted in both aeroponic and geoponic systems. The maximum yield (181.90 q/ha) was found in aeroponic system followed by geoponic system (144.73 q/ha). However, vitamin C content and total carotenoid content were non significantly highest (12.09mg/100g) and (6.13) in geoponic system respectively. Chlorophyll ‘a’ (0.70 mg/g FW) was observed in geoponic system, while chlorophyll ‘b’ (0.119 mg/g FW) under aeroponic system.
