- KRONE is fit for growing within short periods of time under dry conditions.
- Preventive chemical control of Rhizoctonia solani is recommended.
FERTILIZATION
KRONE has a high nitrogen efficiency, so N-fertilisation should be reduced (130-140kg max. including N min.)
phosphorus 100kg/ha
potassium 250-300kg/ha (preferably sulphate)
magnesium 80kg/kg
by low pH-value addition of micronutrients
PLANT PROTECTION
- Krone is not sensitive to Metribuzin
- Routine protective control of late blight is recommended
- addition of a fungicide to chemical haulm killing.
HARVEST
Krone must be senescing before haulm killing.
Take care that skin set is finished before harvest.
STORAGE
- Good dormancy
- Good suitable for a long term storage
