- Intervention effect Mg-deficient rice had higher starch in the leaves.
- Intervention effect Mg deficiency shifted larger biomass partitioning into roots in rice.
- Intervention effect Excess Mg with low K suppressed nitrate reductase activity in rice leaves.
- Intervention effect Excess Mg with low K decreased soluble sugar concentration in rice leaves.
- Observation Potassium and magnesium showed antagonistic and moderately synergistic effects in rice.
- Observation Effects of K on uptake and translocation of nutrients were much larger than those of Mg in rice.
- Observation The optimum K to Mg weight ratio in rice leaves at tillering stage was 22 to 25.
