The results of the use of a yeast preparation on sunflower crops for 2016-2017 have been presented. A positive effect of the researched preparation on the growth and development of sunflower crops of the Neoma hybrid has been established. The preparation Rostmoment increased the height of sunflower plants with a single treatment by 6 cm, and with a two-time treatment of crops by 11 cm, the diameter of the baskets increased by 2.0 cm and 6.3 cm, respectively, against untreated crops. The mass of thousand achenes has been increased by 0.7 g with a single treatment and 2.2 g with a double treatment. The oil content during one-time processing in the basket formation phase was 50.7%, when used twice in the phase of flowering, 51.9%, while in the control its content was 49.2%. Weather conditions in the years of the study significantly affected the productivity of the sunflower of Neom hybrid, especially in terms of moisture supply, and the best conditions for the study of the crop were in 2016, where 209 mm fell during the growing season. precipitation with a uniform distribution. The temperature regime of air on average over the period of sunflower vegetation was 16.5 ºС. The weather conditions of 2017 significantly differed in the amount of precipitation, their distribution and temperature regime, versus 2016. Thus, in 2017, 374 mm of rain fell in the form of prolonged and heavy rainfall, which were unevenly distributed over the decades and months. Such weather conditions caused alternation of excessive moisture and drought during certain periods of growth and development of sunflower plants of the Neoma hybrid, while the average air temperature was 16.2° C. Under such extreme conditions of vegetation periods in the years of research, on average for two years, the yield of sunflower seeds on an untreated experiment was 3.32 t / ha and oil yield 1.64 t / ha. The 2016 yield was slightly higher, 3.43 t / ha and an oil yield of 1.43 t / ha. The use of Rostmoment during a one-time treatment in the basket formation phase led to an increase in yield over two years, which amounted to 3.63 t / ha, and in 2016 - 3.82 t / ha. The use of the studied drug even in the phase of the beginning of flowering contributed to an increase in the yield of seeds in two years to 3.89 t / ha, and in a more favourable 2016 - 4.02 t / ha. The average oil yield per hectare over two years for a one-time treatment of plants was 1.87 t / ha, and for a two-time treatment it was 2.02 t / ha, whereas in 2016 these figures were respectively 1.96 and 2.11 t / ha. The research having been conducted for two years indicated the positive effect of the yeast preparation Rostmoment on sunflower crops, which positively influenced the growth and development of the crops and increased the productivity of the Neoma hybrid in the conditions of the Right-Bank Forest-Steppe. The obtained results are of practical value and can be used by producers in the development and application of technologies for the cultivation of sunflower for increasing the productivity of crops and the ecological state of the agroecosystem. The preparation Rostmoment must be introduced into vegetation plants in the basket formation phase and in the phase of the beginning of the sunflowers’ blossoming, normally 4 kg per 300 l of water per 1 ha of sowing.

The article is devoted to the study of the effect of foliar treatment of Tomatillo plants with the use of drugs of bacterial origin. The paper scientifically substantiates the influence of biologicals on the morphological and biometric parameters of the plant. It was investigated that the emergence of seedlings in varieties Lichtaryk and Pineapple was observed for 7-8 days. After diving and two treatments of plants with drugs, their positive effect on the growth and development of Tomatillo, especially in the phase of budding, flowering and fruiting. A short period of bud formation on the plant was characterized by a variety of Tomatillo Lantern from the use of Biomag. Thus, the beginning of the formation of buds occurred on 66 days on the Lantern variety. A similar effect of the biological product was found during the flowering phase and fruit set. As a result of the activity of Azotobacter chorococum bacteria, the growth and development phases of the Lantern variety are accelerated by 1-3 days compared to the control variant. The use of biological products has had a positive effect on the biometric parameters of the plant. When using bacteria p. Saccharomyces, Azotobacter chroococcum, Paenibacillus polymyxa, Enterobacter nimipressuralis, plant height and stem diameter depended on the type of biological product used. The height of the plant ranged from 82,8 cm to 89,6 cm in the variety Lantern and from 86,8 cm to 91,3 cm in the variety Pineapple. As a result of spraying the plants with Azotobacterin or Rostmoment, the height of the Tomatillo plant exceeded the height of the plant of the variant where biological products were not used. In these variants, the excess of plant height relative to the control was 8,2% for the variety Lantern and 4,3 % for the variety Pineapple, respectively. The diameter of the stem was in the range of 1,9-2,0 cm. Due to the activity of the bacteria Azotobacter chroococcum, Paenibacillus polymyxa, Enterobacter nimipressuralis or yeast p. Saccharomyces and products of their metabolism, revealed a positive effect of biologicals on the increase in leaf area and dry matter content of the leaf. As a result of cultivation of the cultivar Lichtarik and application of Rostmoment or Biopolitsid the area of leaves was at the level of 79,5 thousand м2/ha and 77,6 thousand м2/ha. Growth moment, for the cultivation of the variety Lantern, helped to increase the dry matter content of the leaf by 16,4 %. Treatment of Lantern plants with liquid humus-based concentrate Humisol provided the highest weight of Tomatillo fruit, which was at the level of 8,4 g, and the use of Humisol or Rostmoment for growing varieties Lantern and Pineapple increases the diameter of Tomatillo fruit by 6,9-10,3 %. Humisol, due to humic and fulvic acids, natural phytohormones affects the growth processes of the plant more intensively, which provided in the formation of the largest mass of fruits and their diameter. High yield is characterized by the Tomatillo variety Lantern with five applications of Humisol or Biopolicide, where its value is 33,3 t/ha and 32,0 t/ha. Key words: morphological features, biometric indicators, tomatillo, fruit yield, marketability.

Abstract For the sparsely wooded regions of Russia, and in particular, the Central forest-steppe, new technologies for growing seedlings and seedlings of tree species are extremely important. It provids rapid growth and high survival rate, which is compared to classic technologies. The purpose of our experiment was to establish the effect of temperature screens from pots of various sizes on the temperature in the root zone of the substrate, and, as a consequence, on the growth and productivity of Thuja occidentalis “Smaragd” in plastic pots for three seasons. The most favorable temperature conditions for plants are formed in large pots, which is facilitated by smooth temperature drops in the substrate and a large area of contact between the substrate and the root system. Agrotechnical methods of growing plants have shown the main advantages of “Pot-in-Pot” technology. This is accelerated plant growth due to more efficient use of water and fertilizers on a specially prepared substrate under conditions of minimal temperature fluctuations. Plants, especially large ones, will have a favorable presentation due to better leafing, a well-developed crown, and a large crown diameter. High safety during wintering also increases the efficiency of the technology providing a higher yield and subsequent more intensive growth.

Outdoor experiments were conducted at two locations in Minnesota to characterize the growth, development, and vegetative reproduction potential of giant burreed grown with and without wild rice. Giant burreed growth was influenced by environment more than the presence of wild rice. Shoots emerged from corms 2 to 3 wk after planting (WAP), and continued throughout the growing season. Giant burreed attained a maximum height of 135 cm with an average 36 shoots/plant. Rhizome production started 4 to 6 WAP, and continued throughout the growing season. Corm formation at the base of shoots started 8 WAP and continued throughout the growing season. Rhizomes grew to a maximum cumulative length of 2500 cm/plant spreading in all directions and produced up to 250 buds/plant. Corm and rhizome bud viability was 15 and 10%, respectively. These data suggest that giant burreed grown in wild rice should be controlled by 2 to 3 wk after emergence to prevent vegetative reproduction.
