Revealing the influences of organic amendment-derived dissolved organic matter on growth and nutrient accumulation in lettuce seedlings (Lactuca sativa L.)

| description | Although the application of organic amendment (OA) is a well-established agricultural practice, the effectiveness, optimal concentration, and key characteristics of OA-derived dissolved organic matter (DOM) in promoting the growth and nutrient accumulation of lettuce are not fully understood. To gain a better understanding, the effect of OA-derived DOM that was prepared from rapeseed oil cake (ROC) on the growth of lettuce was examined. Lettuce seedlings (7 days old) were transplanted into a hydroponic nutrient solution with varying DOM concentrations (10, 20, and 30 mg C L–1) along with the control treatment (no DOM addition), and shoot and root growth of lettuce was recorded and nutrient accumulation in lettuce was analyzed after 14 days. Compared to the control treatment, the soil and plant analyzer development value, shoot fresh weight, shoot dry weight, and leaf area were significantly greater (P < 0.05) in 20 mg C L–1 DOM concentration, while the maximum leaf width was significantly higher (P < 0.05) in 10 mg C L–1 DOM concentration. The root fresh weight, root dry weight, root length, root surface area, and number of lateral roots were significantly greater (P < 0.05) in 20 mg C L–1 DOM concentration than in the control treatment. DOM concentrations of 20 and/or 10 mg C L–1 also resulted in enhanced carbon, phosphorus, potassium, sulfur, silicon, and boron contents in lettuce. Overall, these findings suggest that ROC-derived DOM can promote growth and nutrient accumulation in lettuce seedlings, with 20 and/or 10 mg C L–1 being suitable concentrations. |
