The trend for development and spreading of diseases and pests of blackcurrant at Orel region in the conditions of extreme drought in 2010 has been detected. Abnormal weather conditions of the summer and the lack of precipitation limited both growth of host plant and disease spreading. At the background of extreme conditions of 2010 the crop phenophases shifted to earlier dates. The awakening of wintering pathogen structures began in the classic dates of the spring, although in summer their biological cycle went off rapidly. Due to the lack of moisture the disease pathogens failed to fully realize their potential of development and spreading. A favorable aspect of the extreme conditions of vegetation period, the reducing of the protective measures against diseases, is to be admitted. Abnormal weather conditions accelerated the pathogen biological cycles and reduced the stock of wintering infection; meanwhile they provoked colonization of the plants by pests. In extremely high air temperature and lasting lack of precipitation the pests number was intensively increasing, exceeding the maliciousness threshold. Due to the above some additional insecticide and acaricide treatments of berry crops were applied. Thus, the vegetation period of 2010 was described as most favorable for the development and spreading of pests and less favorable for disease pathogens.

Purpose. To determine the efficiency of growing soybean varieties ‘Ustia’, ‘Cordoba’, ‘Estafeta’ depending on the influence of microfertilizers and growth regulators. Methods. Field, laboratory. Results. The article presents the results of studying the efficiency of growing different varieties of soybeans. It was found that in the cultivar ‘Ustia’ the best values of assimilation of photosynthetically active radiation were obtained for the applications of Yara Vita Mono Molitrak in the budding phase (0.25 l/ha) with growth regulator Radostym, and Yara Vita Mono Molitrak in the budding phase (0.25 l/ha) + in the flowering phase (0.25 l/ha) with two studied growth regulators. Similar patterns of the utilization rate of photosynthetic radiation were obtained for the ‘Cordoba’ and ‘Estafeta’ varieties. According to the indicators of the energy balance, the complex use of micronutrient fertilizers and growth regulators in any case pays off with an increase in the yield, which means it is energetically expedient. The maximum coefficients of energy efficiency in the ‘Ustia’, ‘Cordoba’ and ‘Estafeta’ varieties were obtained with the introduction of micronutrient fertilizers Yara Vita Mono Molitrak in the budding phase (0.25 l/ha) + in the flowering phase (0.25 l/ha) and growth regulators Biosyl and Radostym. However, the use of growth regulators separately does not always provide an economic return on investment. In particular, in the variant without Yara Vita Mono Molitrak microfertilizer, the ‘Cordoba’ variety received 28 873 UAH/ha of net profit, while the introduction of growth regulators did not pay off, since there was no significant increase in the yield, and with the use of growth regulators Biosyl and Radostym net profit was within 28824–29179 UAH/ha. In general, the use of micronutrient fertilizer Yara Vita Mono Molitrak with growth regulators Radostim and Biosyl ensu­red guaranteed yield increase. Conclusions. When gro­wing ‘Ustia’, ‘Cordoba’ and ‘Estafeta’ varieties from an energy point of view, it is better to use Yara Vita Mono Molitrak microfertilizer in the budding phase (0.25 l/ha) with the growth regulator Radostym. Under these conditions, the obtained energy efficiency ratio was 3.24; 3.41 and 3.45, and the profit was 31503, 34072 and 34649 UAH/ha, respectively

The article offers short characteristic of Fj hybrid combinations and reveals type of inheritance by the folwiing characteristics: plant height, height of lower bean insertion, quantity of seeds per plant, quantity of seeds per plant, beans per plant, nodes and branches per plant, as well as determines proportion of dominations displaying high heterosis effect. Two superior hybrid populations, namely Amethyst/Miao-ian-Dou and Amethyst/Krasa Podillia, have been selected and are being used to scan for transgressive forms.
