Abstract

Lettuce production is affected by declining soil fertility, high fertiliser costs, and improper fertiliser use, increasing dependence on chemical inputs. However, limited research on aquatic plant-based organic fertilisers and their effectiveness in improving lettuce growth and yield restricts their adoption as sustainable alternatives  Based on this, the present investigation was conducted during the spring season of 2026 at the University of Agriculture and Forestry, Hue University, Hue City, Vietnam, to assess the effect of organic foliar fertiliser derived from aquatic plants on the growth and yield of lettuce. The field experiment was set up in a randomised complete block design with three replications in spring season 2026 and comprised five treatments: control (water spraying); SW Canada (spraying ratio 1:10), SW (spraying ratio 1:10), WH (spraying ratio 1:10) and SW&WH (1:1) (spraying ratio 1:10). The combined application of SW&WH considerably boosted lettuce production and its constituents at p < 0.05. More precisely, applying SW&WH (1:1) (spraying ratio 1:10) together produced the high leaf area (16.0 dm2), and yield (9.32 t/ha) as well as brix content (2.47%), nitrate content (<50 mg/kg). In general, a 1:10 ratio of SW&WH (1:1) may be the best rate for producing lettuce with high yield and quality in the research location.
