DOSAGE

6.4.2- Seed dosing adjustments.

When using high quality certified seeds it is not enough to know the weight
in kilograms distributed by the machine, as the final result of the harvest will
depend on the number of plants which eventually ripen.
Every plant requires a certain amount of land from which nutrients will be
absorbed. Therefore, both a low or an excessive plant density can be detri-
mental. To determine how many kilograms per hectare are to be sown, you
should know the number of plants per square metre that are going to be
planted.
As a guidance, the recommended number of plants per square metre when
sowing wheat or barley in un-irrigated land can be found in following table:
AUTUMN SPRING
Premature sowing, 310 plants per m 2
Premature sowing, 200 plants per m 2
Late sowing: 445 plants per m 2
Late sowing: 265 plants per m 2
Please note that in spring there is less tillering so more seeds should be sown.
MAQUINARIA AGRÍCOLA SOLA, S.L., RECOMMENDS THAT THE FARMER
SEEKS PROFESSIONAL ADVICE ABOUT THIS SUBJECT FROM A TECHNICAL
SOWING CENTRE.
SEED DOSING SHOULD BE ADJUSTED TO EACH TERRAIN, DEPENDING ON THE:
TEXTURE, FERTILIZING LEVEL, PLUVIOMETER RESULTS AND SOWING SEASON,
GRAIN QUALITY, GERMINATING AND TILLERING POWER, ETC.
It should be taken into account that a seed's germinating power is variable
and dependant on multiple factors. It can be experimentally calculated to
be between 70% and 80%, which is practically equivalent to multiplying the
number of grains to be sown by 1,43 or 1,25 respectively.
