The paper is focused on the study and evaluation of quality of the seeding of seeds and
its effect on the biomass yield. The aim was to evaluate the space arrangement of the seeds by
using of polygon method on one field with the repetition for different forward speeds of the drill
machine. For the evaluation there were used digital photographs, which were taken during
repeated measurements of the each value of the forward speed after sprouting of crop. These
images have been used in order to determine the shape and size of the surface area belonging to
the plant. Own software TfPolyM was used for the image analysis. The shape of the polygons
belonging to the individual plants was expressed by values of the shape factor Tf. This factor
characterises the suitability the shape of polygon surface related to the individual plant. By
comparing of the values of the shape factors for different forward speeds of the drill machine we
can determine the optimal value of the forward speed from the point of seed placement uniformity
in horizontal level. During harvest of the crop there was analysed the variability of the biomass
yield in relation to values of the forward speed used during seeding. The most suitable values of
shape factor Tf (0.8519) was recorded for speed of drill machine set on 12 km h
-1
. For other tested
speeds 8, 10, 15 km h
-1 were recorded lower values of shape factor 0.7994, 0.8173 and 0.8449,
respectively. In determination of biomass production for drill machine speed 12 km h
-1
the
greatest yield from 1 m2 was observed. Subsequently, for speeds 8 and 10 km h
-1 was lower about
4.26% and 1.83%, respectively. For tested speeds of drill machinery 15 km h
-1
and above was
observed only a small descent of yields about 0.6%. Fluctuation in yields affected by working
speed then demonstrates fluctuation in sowing rate. It was also observed that the working speed
of sowing machinery also affect the amount of yield directly. However, in case of lowest yield of
straw recorded it was observed even 20% decrease in yield of grains.
