“The drought was maintained during the vegetative phase on two drought-contrasting maize hybrids, ZP6666 (tolerant) and Drami (sensitive), by limiting irrigation and maintaining 50% field capacity (moderate DS), and 25% field capacity (severe DS). Chitosan NPs were sprayed with 100, 200, and 300 mg L-1 corn leaves. Using 100 mg L-1 chitosan NPs significantly increased most characteristics, except RWC, which showed a n…” Show full quote

Title

Chitosan nanoparticles improve corn yield in differentiating maize hybrids under drought stress

Bekhal M. Hama Tikrit Journal for Agricultural Sciences 2025. doi:10.25130/tjas.25.2.13

Other claims from this paper (7)

Intervention effect At 100 mg L-1, chitosan nanoparticles significantly increased most measured characteristics.
Intervention effect Moderate and severe drought reduced kernel yield per pot.
Intervention effect Chitosan nanoparticle spraying increased yield of tolerant maize under moderate drought by 42 percent.
Intervention effect Chitosan nanoparticle spraying increased yield of tolerant maize under severe drought by 10 percent.
Intervention effect Chitosan nanoparticle spraying increased yield of sensitive maize under moderate drought by 8.5 percent.
Intervention effect Chitosan nanoparticle spraying increased yield of sensitive maize under severe drought by 9 percent.
Recommendation The authors suggest 100 mg L-1 chitosan nanoparticles to combat drought effects.
