e0“spraying chitosan nanoparticles on maize leaves increased yields by 42 and 10 percent for tolerant”
t0“Chitosan nanoparticles improve corn yield in differentiating maize hybrids under drought stress”
t1“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 non-significant response in drought-prone maize leaves. The recovery of drought was notable in both hybrids. Water stress as moderate and severe drought stress conditions reduced kernel yield/pot, while spraying chitosan nanoparticles on maize leaves increased yields by 42 and 10 percent for tolerant and 8.5 and 9 percent for sensitive hybrids at both stress conditions respectively.”

Other claims from this paper (7)
- Intervention effect At 100 mg L-1, chitosan nanoparticles significantly increased most measured characteristics.
- Intervention effect Relative water content showed a nonsignificant response to 100 mg L-1 chitosan nanoparticles.
- Intervention effect Moderate and severe drought reduced kernel yield per pot.
- 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.
