- Intervention effect The highest assimilate remobilization (ABR and CDR) under drought occurred with moderate drought stress and 50 ppm abscisic acid.
- Intervention effect Under normal irrigation with 0 ppm ABA, CP, SPAD and grains per ear were highest.
- Intervention effect Under normal irrigation with 0 ppm ABA, grain yield was highest.
- Intervention effect Without magnesium and potassium application, CDR and CP were lowest under moderate and severe drought.
- Intervention effect A ratio of 100 kg magnesium sulfate to 300 kg potassium sulfate gave the highest CP under moderate and severe drought.
- Intervention effect Increasing potassium sulfate relative to magnesium improved grain yield by 16% compared with the control under moderate drought stress.
- Intervention effect Increasing potassium sulfate relative to magnesium improved grain yield by 28% compared with the control under severe drought stress.
- Recommendation Moderate ABA (50 ppm) with 300 kg potassium sulfate and 100 kg magnesium sulfate is recommended to improve maize single-cross 704 grain yield under drought.
