AB  - This paper analyzes the problems related to the reconstruction of a semi-mounted
berry harvester into a self-propelled one specified for exploitation on smaller orchards. The
components of the self-propelled machine, their purpose and mutual functional connection are
described in details, which retained the principle of unilateral picking of half the row of bush
berries from its semi-mounted predecessor. Among the most important general design features,
the following stand out in particular: the drive of the harvester working components, which is
achieved by means of appropriate combinations of hydraulic and mechanical power transmissions,
which allows it to be highly adaptable to different working conditions on the terrain, and the
control device, which is designed to maintain the movement of the machine in the direction set
by the driver, without decreasing the safety and passability requirements of the machine itself.
In the technology of berry fruit production in the Republic of Serbia, the harvesting process is
still the basic limiting factor. Manual picking participates as much as 75% in total production
costs. The costs of mechanical harvesting are between 2.05 and 2.27 times lower in comparison
to manual picking, depending on whether the machine is a towed or self-propelled. The paper
also provides a comprehensive analysis of the energy parameters of work for both versions of
the harvester. The results indicate that power losses on rolling and slipping are lower in the
self-propelled version 10 and 40%, respectively, while in the semi-mounted version the power lost
on the climb is 60-70% lower compared to the self-propelled version. As the harvesting process
is still a limiting factor in berry fruit production, in addition to reducing costs by applying
mechanized solutions, one of the goals of the work is the optimization of applied technical
solutions for the same.

AB  - In agricultural production, sowing is one of the most important agro-technical
operations that influence the quality of the product and yield. The crops sowing quality, including wheat, depends on properly prepared soil, that is, on the quality of soil cultivation.
However, despite well-executed soil cultivation, satisfactory results cannot always be achieved if
sowing is not done in an appropriate manner. The achieved depth of sowing affects the speed of
sprouting, rooting, resistance of plants to low temperature and drought, intensity of budding,
growth and development, and achieving the highest yield in certain conditions. In unfavorable
agro-technical conditions, and especially in the conditions of dry farming, optimal conditions for
high-quality sowing often cannot be ensured by applying the conventional method. Therefore,
new cultivation and sowing systems are being applied in order to perform high-quality sowing
in time. During the experiment, the influences of the tillage system and sowing method on the
sowing depth and the depth of the formation of the tillering nodes were registered. The results
of two-year study are given, where four methods of tillage were applied, namely conventional
tillage at depths of up to 25 cm and three reduced tillage methods at different depths. Reduced cultivation with a discc harrrow was done at a depths between 8 and 12 cm, and reduced
cultivation with rototiller was done at depths of 5-10 cm and 10-15 cm. During the tests, the
sowing depth and the depths of the tillering nodes were determined by direct measuring of the
knots positions of the analyzed plants. Furthermore, it was verified that depth of the knot
has a significant effect on the resistance of wheat to low temperatures during winter and lack
of moisture during summer droughts. Achieved results enable further optimization of applied
cultivation and sowing systems.

AB  - Genotypic variability of root and shoot traits of bread wheat (Triticum aestivum L.) at seedling stage. - Genetika, Vol 53, No.2, 687-702. The evaluation of the embryonic root and stem of bread wheat (Triticum aestivum L.) in the early stage of development (seedling stage) can be a powerful tool in wheat breeding aimed at obtaining progenies with a greater early vigour. It is revealed that genotypes with faster early vigour have produced higher biomass and grain yield. In this study, the evaluation of traits of the embryonic root and the embryonic stem of 101 bread wheat genotypes was preformed at the 10-day old seedlings. The following eight morphological traits of roots and stems were analysed: primary root length, branching interval, the number of roots, total length of lateral roots, angle of seminal roots, stem length, root dry weight and the stem dry weight. Analysed lateral roots included seminal roots. The greatest, i.e. the smallest variability of observed traits was detected in the branching interval, i.e. the stem length, respectively. The highest positive correlation was determined between the primary root length and the total length of lateral roots. The cluster analysis, based on observed traits, shows that genotypes were clearly divided into two main clusters, A and B. The two clusters essentially differed from each other in the values of the following traits: primary root length, total length of lateral roots, root dry weight, stem dry weight and the stem length. Genotypes with shorter primary and lateral roots, lower root and stem dry weight and a shorter stem were grouped in the cluster B. On the other hand, the cluster A encompassed genotypes with values of these traits above or around the average. The values of the remaining analysed traits: the angle of seminal roots, the number of lateral roots and the branching interval varied greatly between obtained clusters. The cluster analysis showed the homogeneity of genotypes originating from Serbia and the region; their values of the root and stem length and weight were mostly around and below the average. However, the values of the angle of seminal roots, number of lateral roots and the branching interval were above average.
