Summary
PubMedWhy it matters This matters because gardeners and farmers struggling with dry summers may be able to use low-cost chloride-containing fertilizers to help their tomato plants stay productive even when water is scarce.
Scientists discovered that giving tomato plants small amounts of chloride (the same element in table salt) helps them handle drought much better than untreated plants. The chloride works by helping the plant control how much water it loses through its leaves and by improving how it takes up important nutrients from the soil. This means a simple, cheap soil treatment could help tomatoes — and possibly other crops — thrive during dry spells.

Researchers found that chloride — a common component of table salt and many fertilizers — can actually help tomato plants survive drought by improving how they manage water and absorb key nutrients.
Key Findings
Chloride treatment improved drought resistance in tomato plants by enhancing their ability to regulate water loss through leaf pores (stomata)
Chloride-treated plants showed improved uptake and balance of essential nutrients under drought conditions, supporting better overall plant function
The drought-resistance effect was linked to both physiological water-management changes and nutritional mechanisms working together
