Abstract. One of the most dangerous and destructive parasitic weed seed is dodder, and due its impact it is registered in the list of crops risk factors and it also affects directly the animal health. At national level, the damage that it generates in agricultural crop production reaches 50-100 % and worldwide it is causing crop losses of 14-15 %. For this reason the forage plant production is determined by the seed purity the in sowing process, at national and international regulations it is required to be 100 % free of dodder seeds, because a single dodder seed can compromise the whole culture. Complete separation of dodder seeds from the basic culture seed mass is a complex and very difficult process, due to its shape, dimensions and its aerodynamic properties, which often are very similar. An effective separation is the magnetic separation method -a process with high complexity that does not affect the basic seed material properties, in which magnetic drums and fine iron powder are used. Due to the fact that dodder seeds have rough external surface on which wrinkles and fine threads can rise, which are filled with iron powder and gain ferromagnetic properties. The magnetic drums retain the dodder seeds or modify their trajectory, drawing them to the rational drum. The basic culture seeds continue their movement to a separation zone due to their smooth outer surface. In this paper, the experimental research will be presented in view of obtaining a seed material "free" of dodder, pursuing the influence of the drum speed on the seed behavior in the process of separation, improving the degree of adhesion of iron powder to the roughened surface of dodder seeds by using two wetting liquids and reducing the number of passes of seeds through the separator.

This paper aims to present the cinematic parameters determination of a drilling equipment design to work in slope degraded terrains, based on field experimental data acquired in normal exploitation condition and also in heavy environmental conditions. This equipment is developed in order conduct forestation and rehabilitation works of degraded lands and to be incorporated on innovative planting technology (degraded soil processing, levelling and terrace surface modelling, planting settlement, etc). This technology answers to the need to implement measures of environmental rehabilitation and enhancement of slope-degraded forestlands, by development several performing equipments that answer to technological needs of this works (land stability, terrace dimensions, type of power source and seedlings planting variety) in order to rise to the performances and to respect the labour safety standards under difficult working conditions. Also, here in presented equipment has a great impact on forestry and pomiculture works, and also on environmental technical works meant to improve soil quality, lowering the surface and depth erosion, rainwater capitalization, lowering the dust pollution and natural calamity risk, and at last to rehabilitate the inland flora.

In context of fruit sustainable technologies was developed the orchards innovative planting technology created to be used especially on heavy environmental conditions, respectively on degraded lands. Nowadays, the slope terrains are a very important topic especially in the in hilly and mountainous areas, where large areas have been deforested, and in this way land degradation phenomena occurred with serious social and environmental consequences on large areas. In order to mitigate and stop those effects, from technologic point of view, must be made specific land restoration works, like terracing, in order to increase land stability and to replant locally vegetation (reforestation, to establish orchards or vineyards in hilly areas). In this paper will be presented the results obtained in experimental land field when was used the innovative technology, fact that demonstrates its usefulness in the community and degraded lands owners, and also to: encourage the economically sustainable activity, establishing orchards and to add value of the degraded lands.

Usually, the planting seedlings for terrain reforestation require a lot of manual labour and high number of workers, in order to minimize these requirements it is necessary to use a mechanical system serviced by minimum two qualified workers to carry out the planting holes. In this way the soil drilling equipment can be used in horizontal ground and also on slope terrains (max. 15º). This mechanism had been designed with an innovative drilling orientation system, which has the possibility to execute vertical planting holes. The kinematic analysis of the soil drilling mechanism was made using dedicated numerical modelling methods and simulation using MATLAB software applied on a specific R-RRR mechanisms that can be used to accurately reproduce the functioning of the experimental model developed by INMA Bucharest.
