Calculation of seeds and number of plants per meter
Planning the plantation - Slippage index
• The tires must have the same calibration.
• Fill up the equipment on the working place only.
• Do not transit with the equipment when there is a load excess.
NOTE
Calculation:
(Distance with load - Distance without load x 100)
Distance without load
To obtain an amount of 100,000 plants per hectare, whose seeds contain:
Germination index = 95%
Physical purity = 90%
Slippage index = 1.05 (5%)
It is necessary to use the formula below to determine the number of seeds to be used
on 1 hectare, considering the losses that may happen due to the germination index, physical
purity and slippage index of the equipment.
Seeds / ha on the plantation = 0.95 x 0.90 = 0.855
100,000 = 116,959.06 x 1.05 =
122,807.00 plants / hectare.
0.855
Based on this and considering the seed compensation to reach the plants number
estipulated beforehand (100,000 plants / ha), the new number of plants must be 122,807.00
plants / ha. Thus, to determine the number of seeds per linear meter that the equipment
must deposit to reach this next number, define how many linear meters exist on 1 (one)
hectare, according to the adopted spacing between row units (a spacing of 0.90 m was
adopted on this example). After that, divide the value of the
new number of plants
by the
obtained result.
10,000 = 11,111.11 linear meters.
0.90
122,807.00 =
11.05 seeds per linear meter.
11,111.11
This equipment must deposit
11.05 seeds per linear meter. To reach this result, it will
be necessary to adjust the sprockets according to the technical table that can be found on
the 'Seed distribution table' page.
