Aim. Studying of black nightshade young plants’ response to the induced mechanical stresses. Methods. Researches conducted in small plot fi eld experiments. Results. Change of sensitivity level of Solanum nigrum L. plants depending on phases of their development at the moment of damage of elevated parts has been proven. Owing to loss of the surface capable to photosynthesis, there is an essential decrease in volumes of photosynthesis at plants of weed survived and their possibilities of ontogeny passage. The deep induced dis- stresses reduce biological effi ciency of plants, their ability to accumulate weight and to form seeds and even lead them to death. Conclusions. The defi ned principles of response of weed plants to the induced mechanical dis-stresses are can be used for working out and ecological receptions of crops protection from weeds.

Owing to the significant differences in the adaptability of state-registered varieties, those which can adapt well to the local conditions should be given preference. There are several high-yielding varieties available in Hungary with excellent agronomic properties, good adaptability and satisfactory baking quality. This study was conducted to analyse the adaptability of 34 state-registered winter wheat varieties tested in the small plot trials of the National Institute for Agricultural Quality Control (NIAQC) at 5–9 locations between 1994 and 1997 based on their gluten quantity and farinographic index. For the comparison of the varieties the evaluation method of Eberhart and Russell (1966) was applied as modified by Bedő and Balla (1977). The qualitative stability and adaptability values of the varieties differ from the adaptability and stability values calculated from the grain yields. Some winter wheat varieties have good qualitative adaptability and stability, while others have special adaptability and poor qualitative stability, but the majority of the varieties do not belong to these groups.

In the small-plot experiment of the Russian State Agrarian University - Moscow Timiryazev Agricultural Academy against potato viruses in 2014-2019 were tested some kinds of preparations with antiviral activity: Pharmayod, GS (100 g/l of iodine); Immunocytophyte, TAB (20 g/kg arachidonic acid ethyl ester); Ecogel, WS (30 g/l of chitosan lactate); Amulet, TAB (composition of linear polyaminosaccharides (chitosan) in succinic acid solution); Zerox, WS (3000 mg /l colloidal silver); Viron, WS (biostimulant based on urea and citric acid with the addition of essential oils). According to the results of the studies, it was found that, in addition to the effect on the causative agents of viral diseases of potatoes, all tested preparations had a stable tendency to maintain or increase the yield of tubers of infected plants. The increase in the yield of tubers ranged from 0.5 to 1.3 kg/m2. In 2016 under the production conditions of Astrakhan region on the potato variety Impala infected with the PVM + PVS and PVM + PVS + PVY virus complexes a comparative assessment of the effect of Pharmayod and Immunocytophyte revealed a significant increase in the gross and marketable yield of potato plants in the areas with the use of these preparations compared to with control.
