Abstract

Lettuce (Lactuca sativa L.) productivity in Vietnam remains below the global average due to poor agronomic practices and inadequate nutrient management. Excessive reliance on chemical fertilisers leads to soil degradation and environmental concerns, while the potential of organic sources like shrimp waste remains underutilised. Therefore, determining optimal application rates of liquid organic fertiliser derived from shrimp waste is essential to enhance yield, soil health, and sustainable lettuce production. Thus, the purpose of this study was to evaluate the best rate of liquid organic fertiliser from shrimp waste on the growth and yield of lettuce. Four rates of liquid organic fertiliser from shrimp waste (0, 1, 2 and 3%) based on 15 t/ha of compost from mushroom byproducts and 500 kg lime/ha were carried out in the spring season 2026 at Hue city, Vietnam. The experiment was arranged in a randomised complete block design with three replications. The results showed that there was a substantial (p<0.05) effects of different rates of liquid organic fertiliser from shrimp waste on plant height, leaf parameters and total yield as well as lettuce quality. Applying 3% of liquid organic fertiliser from shrimp waste (LOFS) resulted in the highest plant height (22.4 cm), leaf area (108.7 cm2) and SPAD (18.1) as compared with the control. Maximum economic yield (8.3 t/ha) and brix content (2.1%) values were also found in this application rate. Fertiliser use efficiency was the highest at a rate of 2% (LOFS). Nitrate contents were very low at all rates of LOFS application, ranging from 10.0 to 83.3 mg/kg. In conclusion, lettuce cultivated with 2 - 3% of LOFS based on 15 t/ha of compost and 500 kg lime/ha exhibited superior growth and production.
