- Manganese is a constituent of some respiratory enzymes and of some enzymes involved in protein synthesis.
- Manganese may increase the incorporation of sugars into starch, resulting in an increased photosynthetic rate.
- Availability in soil declines with increasing pH; manganese can form complexes with organic matter.
- Deficiency or toxicity can result in reduced plant growth reduced number of stolons.
- The fastest rate of uptake occurs 30 – 40 days after emergence.
Foliar application of manganese
- Rate of application = 600 g Mn ha-1. More …
- “Sufficient” concentration on foliage = 30 – 250 ppm Mn when plants 30 cm high. More …
- Do not apply while stolon tips are swelling.
- Do not apply in a tank mix with both magnesium and zinc. More …
