Salinity problem is increasingly affecting tomato production in Lebanon leading to
economic losses.
The study investigated the potential effects of nano

due to improvement in fruit number rather than fruit
weight.
Consequently, LITHOVIT® and MKP showed superior effects under salt stress compared to
Aspirin and Glycinebtaine.
