Cascade cropping systems (CCS) utilize leachate from a primary crop to grow secondary crops and enhance the efficient use of water fertilizers in areas with scarce resources. A preliminary study investigated effect melatonin cascade system potentially improve plant tolerance abiotic stresses. This aimed cultivate Salicornia fruticosa this reduce nutrient discharge assess impact exogenous on growth quality. The CCS included grown an agro-industrial compost or peat. Leachates these media were used same once again floating under four treatments: (T1), peat (T2), 100% solution (NS) (T3), 50% NS (T4) strength. Four concentrations applied foliar spray: 0, 100, 200, 400 µM. Melatonin application increased yield, highest values observed when plants T1. Water efficiency was also maximized T1 both 200 µM applications. nitrogen achieved leachate. lipid membrane damage assessed revealing that exhibited lowest MDA regardless concentrations. accumulation some antinutritional compounds (nitrate, oxalate, sodium) those Overall, shoots best phytochemical profile (total phenol content, total flavonoids, antioxidant capacity), peak treated melatonin. These findings suggest S. can be effectively cultivated using previous enhances yield nutritional quality shoots.
