This study investigates the biofortification of tomato and lettuce plants with strontium (Sr). The Sr was applied at 0, 25, and 50 mg kg-1 in the soil experiment and 0, 2.5, and 5.0 mg L-1 in the rockwool experiment. The Sr application increased growth of plants. The Sr concentration in soil-grown tomato increased from 137 to 384 and 665 mg kg-1 with Sr treatments, respectively. Similarly, Sr concentration in tomato fruits rose from 4.53 to 10.7 and 17.5 mg kg-1. Lettuce Sr concentration increased from 64.9 to 119 and 168 mg kg-1 with Sr treatments. The Sr concentration in the vegetative parts of tomatoes grown in rockwool increased from 23 to 600 mg kg-1 with low-Sr and to 604 mg kg-1 with high-Sr application. Similarly, the Sr concentration in tomato fruits increased from 1.13 to 25.7 and 19.0 mg kg-1 with Sr treatments. The Sr concentration in lettuce grown in rockwool increased from 26.2 to 285 and 356 mg kg-1 with Sr, respectively. The fruit Ca concentrations significantly increased in response to the applied high-Sr in soil-grown tomato plants. In rockwool-grown tomato, the Ca concentrations in the vegetative parts increased from 19.3 to 27.8 g kg-1, and in the fruits, it increased from 0.66 to 1.00 g kg-1 under the low-Sr treatment compared to the control. In rockwool-grown lettuce, the Ca concentration increased with the low-Sr. In conclusion, the present research establishes that the biofortification of Sr in the edible parts of tomato and lettuce plants can be achieved successfully.
