SOWING
The
success of all crops begins with an opportune sowing date an appropriate
depth and mainly a good population density depending from the material
to sow. The hybrid Sefloarca are designed for the tropic and they
should be sowed populations between 45.000 and 50.000 plants/hr
which can be gotten following the following square:

This population is obtained sowing between 16-19 kg of seed/hr according
to the size
FERTILIZATION
All
fertilization plans should leave of a floor analysis. Once established
the n-p-k doses, to apply this way: the whole phosphorus, half of
the nitrogen and half of the potassium in the sowing and the nitrogen
rest and potassium between the 25 and 30 days. The repayments with
potassium guarantees bigger grain quality, better adaptation to
hydric stress, minor flattens and bigger yield.
CONTROL
OF OVERGROWTHS
The
cultivation of corn should remain free of overgrowths during the
first 30 days from the sowing; being this the stage more crucial
of competition with the overgrowths, where the biggest yield reduction
occurs. Therefore herbicides should be used pre-sowing and / or
pre-emergent leaving the control post - emergent for possible rescues
of the cultivation.
ASPERSION
EQUIPMENT
- Gauge
the sprinkler appropriately according to the product to apply
and the volume for required hectare.
- Select
mouthpieces fan for herbicides and conical for insecticides and
fungicides.
- Make
the triple laundry with the empty containers and use the content
in the cultivation.
-
Making maintenance of their equipment saved time and money and
it will protect the environment.
