A synchronized and uniform flowering remains the main goal to be pursued in this phase, so you must carefully manage nitrogen and pay special attention to possible biotic and abiotic stresses that may occur. The nutrition in vegetative response must therefore promote a balanced vegeto-productive development.
The technical line
- BluActive 300-400 kg/ha - granular, at the soil
- Hydrostar BTC 10 kg/ha - 2 applications in fertigation every 15 days
In case of forecast low temperatures and cold returns:
- Cerere at a dose of 1-1.5 litres/ha 24-48 hours before the onset of heat loss (also usable in case of full flowering).
In case of recurrent ferric chlorosis set the first application in vegetative recovery/sprouts development of:
- Nano. T Fe 5 l/ha + SuprEmo 20 l/ha
Technical in-depth analysis:
For the apple tree to check if it has received enough cold hours you must:
- Determine the "cold" period (e.g. October-January)
- Count the number of hours in this period below 7.2 °C.
- Consider that the required requirement is between 1000-1200 hours.
