Climate Adaptation
The melons in your grocery store may soon be grown with a third less water by farmers using simple plant boosters — meaning more fresh fruit even as droughts become more common.
Scientists tested what happens when you water melon plants less than normal but also spray them with a special liquid made from amino acids (the building blocks of proteins). They found that using about 75% of the usual water amount, paired with the right dose of this plant booster, kept the melons healthy and tasted just as good. This is great news for farmers in hot, dry places where water is running out and the soil is getting too salty.
Key Findings
Deficit irrigation at 75% of available soil water maintained melon fruit quality comparable to full irrigation
Amino acid-based biostimulant application at optimized rates improved plant tolerance to both water stress and soil salinity
The combination of moderate water deficit and biostimulant use enhanced water use efficiency without yield or quality loss across three growing seasons (rainy, transition, and dry) in 2023
chevron_right Technical Summary
Researchers found that giving melon plants slightly less water than usual, combined with an amino acid-based growth booster, produced healthy fruit while using water more efficiently in dry, salty growing regions.
Abstract Preview
Water scarcity and soil salinization are major constraints to irrigated agriculture in semi-arid regions, affecting crop productivity and fruit quality. Combining deficit irrigation with biostimula...

A melon is any of various plants of the family Cucurbitaceae with sweet, edible, and fleshy fruit. It can also specifically refer to Cucumis melo, commonly known as the "true melon" or simply "melon". The term "melon" can apply to both the plant and its fruit. Botanically, a melon is a kind of be...
