Purpose. To reveal features of formation of productivi­ty and quality of commercial products of parsnip (Pastina­ca sativa L.) depending on ways of application of growth regulator Bioglobin in the conditions of the Western Fo­rest-Steppe of Ukraine. Methods. Field, laboratory, analytical and statistical. Results. With the introduction of the growth regulator Bioglobin, the mass of a parsnip root increased from 207 to 249 g (control – 196 g). A large mass of roots – 244 and 249 g – was observed when proces­sing seeds with Bioglobin (0.5 l/ha) + foliar fertilization in two stages and seed treatment with Bioglobin (0.5 l/ha) + foliar fertilization in three stages, which is higher than control (without treatment) for 48 and 53 g, or 20.4 and 27.0%, respectively. High yields of roots of parsnip cultivar ‘Stymul’ were obtained in 6 and 8 variants of the experiment – 53.5 and 54.7 t/ha, yield increase was 10.3 and 11.4 t/ha, or 23.8 and 26.4% in accordance. There is a strong relationship (r = 0.98 and 0.99) between yield and weight of parsnip root. Qualitative indicators of root crops (dry matter, amount of sugars and vitamin C) improved with increasing number of treatments with growth regulator Bioglobin. There is a tendency to decrease the concentration of nitrates in roots with increasing number of treatments with growth regulator. In general, the content of nitrate nitro­gen in the roots in all variants of the experiment did not exceed the threshold limit value (TLV) (400 mg/kg of raw weight). Conclusions. An increase in the number of treatments for parsnip seeds and foliar application of the growth regulator Bioglobin ensured an increase in the mass of root crops, an increase in their yield, marketability and an improvement in the quality of commercial products. The highest yield – 54.7 t/ha of marketable root crops of parsnip variety ‘Stymul’ was obtained when processing seeds with Bioglobin (0.5 l/ha) + foliar feeding in three stages.

Fertilizer Rates

In recent years, interest in non-traditional methods of farming and plant growing has increased, which include the widespread use of biological methods of plant protection and nutrition, allowing significantly reduce the use of pesticides and reduce fertilizer rates. Therefore, there is a constant search and selection of highly effective and competitive formulations that, in growing technologies, ensured an increase in yield and the quality of the grown products. It has been established that the reasons for obtaining seeds of low yielding and sowing qualities of winter wheat in the zone of excessive moisture in the Western Forest-Steppe of Ukraine are lodging of crops and the development of harmful diseases. These negative phenomena can be prevented through the use of the Vympel-2 growth regulator and Oracle microfertilizer colofermin copper, both when separately and simultaneously introduced into the ejection phase of the tube. Under the influence of these formulations, resistance to lodging of plants increases, the spread of diseases decreases: powdery mildew, leaf septoria, and dark brown rust. The increased spike growth and the best filling of winter wheat grains occur due to the shortening of the vegetative part of the shoot, which contributes to a significant increase in productivity - 0.45–0.55 t / ha. Due to optimal growth and development, seeds of high sowing qualities are formed on maternal plants. The most effective is the tank mixture of the Vympel-2 growth regulator (0.5 l / ha) with microfertilizer Oracle colofermin copper (1.0 l / ha) against the background of N30P90K90 with the phased introduction of nitrogen according to N30P90K90 at the IV and VII stages of organogenesis, which reduced development diseases on plants compared with the control (without treatment of sowing) by 15.4% (powdery mildew), 10.8 (leaf Septoria) and 10.4% (dark brown spotting).

Abstract Pot experiments conducted in a growth chamber studied the effectiveness of foliar fertilization of spinach (Spinacia oleracea L.) with macro- and microelements in the form of a 1% water solution of Insol U fertilizer applied with fluorescent light of the PAR intensity of 200 μmol m-2 s-1 and with dispersed daylight of the intensity of 600 μmol m-2 s-1. Insol U was applied three times, supplied on the upper, lower or both sides of the leaf blades. The control consisted of plants sprayed with distilled water. The obtained results pointed out that foliar fertilization of spinach with Insol U significantly increased the leaf gas exchange, the yield of the fresh leaf mass, the content of vitamin C, chlorophyll, carotenoids, as well as potassium and phosphorus in the leaves. The application of the fertilizer onto the upper and the lower side of the leaf blade had the most positive effect on the analysed property of the leaves. Independently of the side leaf, the application of the fertilizer at a higher light intensity had a significantly better consecutive effect on all the analysed properties of the leaves.

The objective of the vegetation experiment established in 2008–2011 was to explore the effect of the time and dose of foliar molybdenum (Mo) application on the yield and quality of sunflower. Four treatments were established in the experiment: (1) control – not fertilised with Mo; (2) application of 125 g Mo/ha in the growing stage of 4 developed leaves (V-4); (3) application of 125 g Mo/ha at the beginning of elongation growth (R-1), and (4) split rate of Mo application of 62 g Mo/ha at stage V-4 (4 developed leaves) and 62 g Mo/ha at stage R-1 (terminal bud forms). Foliar application of molybdenum increased the biomass production of sunflower plants and its content in dry matter. A statistically significant effect of molybdenum foliar application on sunflower yields was found. Foliar application of Mo up to a dose of 125 g Mo/ha at the beginning of vegetation (stage V-4) and developmental stage R-1 increased yields of achenes. The relative increase in the oil content after foliar nutrition was not significant and ranged between 1.4% and 2.6%. Oil production increased due to increased yields and stabilised oil content. Foliar application of molybdenum had no effect on the content of oleic acid.

Наведено результати досліджень впливу регулятора росту рослин «Грейнактив-С», що застосовується для передпосадкової обробки садивних коренеплодів цукрових буряків, на процеси формування насіннєвої продуктивності висадків та посівні якості гібридного бурякового насіння, а також на розвиток морфологічних елементів насіннєвих рослин. У результаті польових досліджень було встановлено, що обробка садивних коренеплодів цукрових буряків регулятором росту рослин «Грейнактив-С» за 12 годин до їх висаджування сприяє кращому відростанню висадків і збільшенню їх висоти, порівняно з контролем, на 8,0 і 28,7% відповідно. Ураження рослин висадків буряків мозаїкою і некрозом судин листя на ділянках із «Грейнактивом-С» виявилось у 1,41 і 1,52 рази, відповідно, меншим порівняно з варіантом, де коренеплоди не оброблялись цим препаратом. Застосування «Грейнактиву-С» для обробки садивних коренеплодів перед їх висаджуванням сприяло зменшенню у 2 рази кількості насінників цукрових буряків, заселених листковою буряковою попелицею. Препарат «Грейнактив-С», що застосовувався для обробки садивних коренеплодів, сприяв збільшенню врожайності гібридного насіння буряків на 11,5 %, маси 1000 плодів – на 14,0 %. На 5-й день кількість схожого насіння в термостаті на відповідному варіанті виявилася на 10 % більшою, ніж на контролі, а ростковість – у 1,3 рази більшою, ніж на контрольному варіанті. To solve the problem of increasing the seed productivity of sugar beet deforestation, and, having low costs for their cultivation, it is possible not only by genetic selection methods, the application of mineral fertilizers and pesticides, but also by means of growth regulators of plants that become integral elements of intensive technology growing this crop. All this testifies to the relevance of the study of the influence of the growth regulator of plants «Grainaktiv-S», which was used for the processing of seedy root crops of sugar beet, on the processes of growth and development of planting of plants, as well as on the seed quality of the hybrid beet seed. As a result of field studies, it was found that the treatment of sugar beet seedy root crops 12 hours prior to their planting by the growth regulator «Grainaktiv-S» contributes to a better growth of landings and an increase in their height compared with control of 8.0 and 28.7 %, respectively. The damage to beet plants by mosaic and necrosis of leaf vessels on sites with «Grainactiv-C» was 1.41 and 1.52 times lower, respectively, compared to the variant where the root crops were not treated with this drug. The number of seeds of sugar beets populated with leafy beetroot aphids was 2 times lower in the variant where «Grainaktiv-S» was used for processing root crops before planting. The drug «Grainaktiv-S», used to treat the planting root crops, contributed to an increase in the yield of hybrid beet seeds by 11.5 %, and a weight of 1000 fruits – by 14.0 %. On day 5, the number of similar seeds in the thermostat in the corresponding variant was 10 % higher than that of the control, and germination in the same variant under the conditions of the thermostat on the 5th day was 1.3 times higher than in the control version.

In the results conducted between studies, the studied regulators affect the biometrics and yield of table carrot plants. The greatest influence on the interphase period "root formation - technical maturity" was performed by the regulator Phytocid-r, which helped reduce the growth of the interphase period Shantane KL by 3 days, in the hybrid Brilliance F1 by 4 days. With the use of the growth regulator Phytocid-r of the vegetation period of the population in the variety Shantane KL – 117 days, in the hybrid Brilliance F1 – 118 days, respectively 6 and 7 days shorter with control. The highest weight of root crops during the growing season was observed using the growth regulator Phytocid-p, in the variety Shantane KL the increase relative to control was 15.5 – 23.7 g, in the hybrid Brilliance F1 – 18.5 and 25.5 g. root crops were also characterized by variants using growth regulators Ivin and Emistym C, where the increase relative to the control at the end of the growing season was: in the variety Shantane KL – 4.1-8.3 g, in the hybrid Brilliance F1 – 4.9 and 6.0 g respectively. The growing season of table carrots was characterized by slightly higher temperatures and low rainfall, with a long dry period, which negatively affected the formation of roots of table carrots. However, the highest yield was obtained from the option using the growth regulator Phytocid-p, which provided an increase in yield at the level: in the variety Shantane KL – 8.5 t / ha, in the hybrid Brilliance F1 – 13.3 t / ha. The highest percentage of marketable yield was obtained using the growth regulator Phytocid-p in both varieties and hybrids – 94.8 and 95.2 %, which is more than the control by 11.2 and 11.0 %. The largest mass of root crop was formed by plants using the growth regulator Phytocid-r: in the variety Shantane KL – 112 g, in the hybrid Brilliance F1 – 118 g, which is 23.8 and 25.6 g more than the control. The diameter of the root was in the range of 5.8-7.0 cm and varied slightly from the growth regulator. The hybrid Brilliance F1 was characterized by a longer root length. However, taking into account the applied growth regulator, it was found that the highest figure was for the use of Phytocid-r: in the variety Shantane KL – 17.6 cm, in the hybrid Brilliance F1 – 18.3 cm, which is more than the option without treatment 1.2 and 1.0 cm.

Fertilization Level

Soil tillage and fertilization level are important in the system of agro-technical measures that increase soil fertility and sugar beets productivity. Today the cultivation of this crop requires a great deal of expense, therefore, there is a need for a wider study of the use of cheap soil cultivation, soil protection, energy-saving soil tillage technologies and appropriate ferti-lization levels. Under western Forest-Steppe of Ukraine conditions, investigations were conducted on dark grey podzolic light loamy soils where the influence of tillage models and fertilization levels on the formation of sugar beets root crops was studied. Shallow no-plow tillage of the soil on 14-16 cm is expedient to use as a main tillage under sugar beets. Under favorable weather and climatic conditions, it can provide yielding capacity at the level of deep fall plowing. The use of shallow no-plow tillage helped to increase the yielding capacity of sugar beet roots relative to plowing by 28-30 cm for 1.3 t / ha and the biological sugar output – for 0.2 t / ha. Then the sugar content was by 0.1% higher in the application of deep fall plowing on 28-30 cm. The optimization of the system of sugar beets fertilization allows ensuring the growth of the yielding capacity of root crops. It is established that the application of fertilizer norm N300P225K350 provides the yielding capacity at the level of 90 t / ha. The sugar content of root crops at the given fertilizer rate was the lowest in the experiment - 16.5 – 16.6%. Thanks to the high yielding capacity of root crops in terms of N300P225K350, the sugar harvesting was the highest and depending on the method of basic soil tillage was 14.95 – 14.79 t / ha. That is in 3.2 times more as to the control, in 1.3 times more than the norm of N180P135K210 and in 1.1 more than the fertilization level N240P180K280.

The productivity of agricultural crops is the most variable and integral indicator of their vital activity, which accumulates their genetic potential, soil fertility, weather conditions and components of agricultural technology. Soybean under optimal growing conditions (the reaction of the soil is close to neutral, sufficient phosphorus and potassium nutrition, the use of nitraginization) assimilates from the air about 70 % of the total nitrogen requirement. Therefore, it is believed that it is enough to apply only a starting dose of nitrogen fertilizers (20–40 kg/ha a. s.), to get a high yield with good indicators of grain quality. The results of studies of the influence of long-term (8 years) application of different doses and ratios of fertilizers in field crop rotation on podzolized chernozem in the conditions of the Right -Bank Forest-Steppe of Ukraine on the yield and quality of soybean seeds preceded by spring barley were presented. It was found that crop yields could be increased by 18–77 % owing to different doses, ratios and types of fertilizers. The highest indicators of seed yields for three years of the research (3,02 t/ha) were obtained under the application of mineral fertilizers at a dose of N110P60K80 per 1 ha of crop rotation area, including under soybean – N60P60K60. Exclusion of the nitrogen component from the complete fertilizer (N60P60K60) reduced its yield by 26 %, phosphorus – by 17, and potassium by 11 %. There was no significant decrease in soybean yield in the variant of the experiment with a decrease in the proportion of potassium in the composition of complete mineral fertilizer (N60P60K30) for three years of study. The largest mass of 1000 soybean seeds was formed at doses of N60К60 fertilizers, and their protein content — under the application of complete mineral fertilizer in doses of N60P60K60 and N60P60K30.

Introduction of complex mineral fertilizer of an azofoska in combination with ammonium nitrate and urea to early ripe potatoes of Zhukovsky and Red Scarlett variety on the planned productivity of 40 t/hectare has allowed to achieve a goal. At the same time in control option without fertilizers the productivity was 23,2-24,8 t/hectare. Use of encapsulated urea has led to decrease in productivity and level of profitability by 26,3-30,9%. Early ripe potatoes of Zhukovsky and Red Scarlett variety on natural fertility of the chernozem leached in the northern forest-steppe of the Tyumen region have created average yield of 23,2-24,8 t/hectare for years of researches. Use of complex mineral fertilizer of an azofoska in combination with ammonium nitrate and urea on the planned productivity of 40 t/hectare has led to increase in productivity on the first variety to 39,5 on the second variety up to 41,4 t/hectare. Introduction of the encapsulated urea has led to decrease in productivity of the early ripe potato tubers studied. At the same time, the peel was gentle and when cleaning it was strongly injured. As to the content of starch (11,9-12,6%) at both varieties the big difference between ex-perience options isn't revealed. The similar picture was observed also according to tastes of tubers. It has made 3,2-3,5 points at Zhukovsky variety and 3,4-3,7 points at Red Scarlett's variety. Profitability level in con-trol option at Zhukovsky variety was 157,3%, at Red Scarlett's variety – 140,5%. In options with non-encapsulated ammonium nitrate and urea the first variety got 172,6-184,1%, second variety – 190,4-207,2%. In option with encapsulated urea at varieties under study the profitability level has decreased 26,3-30,9.
