| Abstract | ||
| Raising plant tolerance to environmental stress, particularly salinity is necessary. So, a pot trial was conducted to assess the impact of different compost types; normal compost (NC) and enhanced compost (EC) at a rate of 10.0 Mg ha-1, with a control treatment (without soil addition) on the performance and storability of crisphead lettuce plants grown on salt-affected soil. Additionally, the exogenous application of selenium at the rate of 500 ppm (as sodium selenite, Na2SeO3) and silicon at the rate of 600 ppm (as potassium silicate, K2SiO3), was assessed. Results indicated that compared with control, the highest values for growth, yield parameters total chlorophylls, vitamin C, and edible head weight were observed in plants treated with EC, followed by those treated with NC. Conversely, plants grown without compost exhibited maximum values for total phenols, reactive oxygen species, SOD, PPO, and APX. Concerning foliar application of microelements, selenium treatment proved superior than that of silicon. Furthermore, the studied treatments prolonged crisp-head lettuce storability parameters compared to plants without compost and beneficial elements (control). Specifically, the weight loss percentage of crisp head lettuce was significantly reduced during the storage period. The combined treatment of EC and selenium fertilization demonstrated the most promising effect regarding storability. So, this combined treatment could be recommended for improving crisphead lettuce performance and quality over an extended storage period. | ||
