The Impact

In the formation of the winter wheat yield, the protection of the crop from pests, stress, pesticides and adverse abiotic factors is one of the important elements of the technology. To increase yield and reduce the impact of adverse factors in winter wheat protection systems, plant growth regulators are used. In the conditions of the Ryazan region in 2019-2020, the effectiveness of the use of tank mixtures of pesticides with the growth regulator Energia-M (0.01 kg/ha) in the protection systems of winter wheat of the Danaya variety was studied. In the variant with the use of a tank mixture of pesticides with a growth regulator, a statistically significant excess of yield was noted in comparison with the control (without treatment) by 1.4 t/ha (31 %) and with the variant with treatment using a tank mixture without the use of a growth regulator - by 0.9 t/ha (18 %). Under the influence of the plant growth regulator, a decrease in the negative impact of pesticides on growth processes, an increase in crop yield by 18 % due to the formation of an additional number of productive stems (80 pcs / m2 ) were noted and a higher net operating profit was obtained compared to the protection system without a plant growth regulator.

Content of the chlorophylls and carotenoids in a pigment complex is one of the most important factors that determine the productivity of crops of cereals. Although it is well known that herbicides and plant growth regulators may cause changes in the amount of pigments, there is lack of researches about their separate and integrated influence on the pigment complex of grain sorghum (Sorghum bicolor (L.) Moench). Therefore, we aimed our research to investigate the response of grain sorghum’s pigment complex to the impact of the herbicide in different combinations with the plant growth regulator and biopreparation. In result, it was found that the content of the pigments was decreasing simultaneously with increasement of the herbicide rate. However, the obtained data indicates that the complex usage of the herbicide and plant growth regulator had an auspicious influence on the pigments content, compared to the variants where only herbicide was applied. The similar auspicious effect appeared, when the herbicide was applied on the background of pre-sowing seeds treatment by the biopreparation Bioarsenal. It is noticeable that in this case the increasement of pigments content was higher than in the variants of compatible application of the herbicide and plant growth regulator. The highest indicators of the pigments content formed when the herbicide was applied compatible with the plant growth regulator on the background of pre-sowing seeds treatment. The content excess of the chlorophylls a, b, a+b and carotenoids, relatively to the control, amounted 7,4 – 9,1%, 16,0 – 18,3%, 9,4 – 11,2% and 35,5 – 40,2% respectively. It is evident that usage of the herbicide Citadel 25 OD compatibly with the plant growth regulator Endofit L1 on the background of pre-sowing seeds treatment by the biopreparation Bioarsenal is an effective measure, which allows to reduce the harmful impact of the xenobiotic on the pigment complex of grain sorghum

Наведено результати досліджень стосовно впливу гербіциду «Панда», регулятора росту рослин «Стимпо» і мікробного препарату «Ризобофіт» на забур’яненість та густоту посівів нуту сорту Пам’ять в умовах Правобережного Лісостепу  України. Встановлено взаємозв’язок між дією різних норм гербіциду «Панда» і біологічних препаратів на видовий, кількісний склад бур’янів та густоту культурних рослин у посівах нуту. Відзначено дію гербіциду як ефективного заходу боротьби із сегетальною рослинністю в нормах 3,0–4,0 л/га. Досліджено, що найменша кількість і маса бур’янів у посівах, без значного зниження щільності рослин нуту, відзначалися у варіантах за поєднаного використання ґрунтового гербіциду «Панда» в нормах 3,0–4,0 л/га, регулятора росту рослин «Стимпо» (0,025 л/т) та мікробного препарату «Ризобофіт» (1,0 л/т). Сумісна дія гербіциду з біологічними препаратами у даних варіантах досліду забезпечила зниження забур’яненості посівів за кількістю проти контролю І на 76–85 %. При цьому густота рослин у посіві знизилася лише на 2–3 %. На основі проведених досліджень встановлено найефективнішу комбінацію використання препаратів, що забезпечує підвищення продуктивності посівів, зниження їх забур’янення та є екологічно безпечною для навколишнього середовища. The article provides the results of the investigation of the impact of the herbicide «Panda», the plant growth regulator «Stympo» and the microbial preparation «Ryzobofit» on the weediness and crop density of chickpea of the breed Pamiat in the conditions of Right-Bank Forest-Steppe of Ukraine. We established the connection between the act of different limits of the herbicide «Panda», the plant growth regulator «Stympo» (0.025 l/t) and the microbial preparation «Ryzobofit» (1.0 l/t), the quantitative content of weeds and the density of crop plants of chickpea. We determined the effective action of the herbicide against growing in grain fields in limits 3.0–4.0 l/ga. It was investigated that the least amount and mass of weeds in crops, without substantial decrease of cheakpea density, was distinguished while combining the soil herbicide «Panda» in limits 3.0–4.0 l/ga, the plant growth regulator «Stympo» (0.025 l/t) and the microbial preparation «Ryzobofit» (1.0 l/t). The joint effect of the herbicide and the biological preparations in the given variants of the investigation provided the decrease of weediness of crops in the amount against the control I on 76–85%. Moreover, the density of plants decreased only on 2–3%. On the base of the conducted experiments the most efficient combination of the usage of preparations was determined – the growth regulator «Stympo» (0.025 l/t), the microbial preparation «Ryzobofit» (1.0 l/t) and the soil herbicide «Panda» in limits 3.0–4.0 l/ga, which provides the increase of crop productivity, decrease of their weediness and which is environmentally friendly.

The Impact

An experiment was conducted at the Horticulture Farm of Bangladesh Agricultural University, Mymensingh to test the impact of plant growth regulators on growth and yield of summer tomato. The experiment consisted of two tomato varieties viz. BARI Hybrid Tomato-4 and BARI Hybrid Tomato-8 and four types of plant growth regulator (PGR)viz.,(i) control (without PGR), (ii) 4-CPA (4-chlorophenoxy acetic acid), GA3 (gibberellic acid) and 4-CPA +GA3. The two-factor experiment was laid out in randomized complete block design with three replications. The results of the experiment revealed that significant variations were observed for most of the characters studied. At 75 DAT, the tallest plant (79.35 cm), number of flowers and fruits (38.11 and 19.04, respectively) plant-1, individual weight (58.44 g) and fruit yield (22.75 t ha-1) were found in BARI Hybrid Tomato-8.At 75 DAT the maximum plant height (87.90 cm), number of flowers and fruits (49.04 and 21.9, respectively) plant-1, individual fruit weight (61.16 g), and fruit yield (27.28 tha-1) were found when 4-CPA + GA3 applied together, whereas the minimum for these characters were recorded from control plants. In case of combined effect of variety and plant growth regulator, the maximum plant height (87.90 cm), number of flowers and fruits (49.04 and 21.91, respectively) plant-1, individual fruit weight (61.16 g) and fruit yield (27.28 t ha-1) were observed in BARI Hybrid Tomato-8 when treated with 4-CPA + GA3together, and the minimum for all these parameters were found in control plants. The results of the present study suggest thatboth 4-CAP and GA3together can be practiced for increasing summer tomato production for both the varieties.Progressive Agriculture 26:32-37, 2015

The article presents the results of researching the impact of foliar fertilization with microfertilizers Ecolist Mono Zinc and Rostok Corn, plant growth regulator Vimpel and bacterial preparation Biomag on the complex of economically valuable traits and productivity of maize hybrids of different maturity groups (early ripening group: Kharkiv 195 MV, (FAO 190), DKS 2960 (FAO 250), DKS 2949 (FAO 190), DKS 2971 (FAO 200), middle-early: DKS 3472 (FAO 270), DKS 3420 (FAO 280), Pereyaslavsky 230 SV (FAO 230), DKS 3871 (FAO 280) and medium-ripe: DK 391 (FAO 320), DK 440 (FAO 350), DKS 4964 (FAO 390), DK 315 (FAO 310)). The dependence of foliar fertilization usage and the starch content in corn grain is generalized. One-time foliar feeding provided a starch content increase by 0.1-0.5%, double feeding - by 0.85-1.30%. The yield of starch was in hybrids DK 391 - 8,748 t / ha, DK 440 - 8,821 t / ha, DKS 4964 - 9,559 t / ha, DK 315 - 9,314 t / ha with a single feeding and with a double feeding it was significantly higher - 9,220 t / ha, - 9,384 t / ha, 10,142 t / ha, 9,993 t / ha, accordingly. The highest yield of starch in all hybrids was provided by double application of microfertilizer Ecolist Mono Zinc (8,983-10,595 t / ha) and Rostok corn (8,721-10,597 t / ha), the increase in starch yield with the use of these fertilizers was 0.5-1.8 t / ha, relative to control (water supply). It is established that in dry years with high temperatures (2012) there is a decrease in starch content, regardless of the studied vegetation factors and cultivation technology. Foliar fertilization contributed to an increase in the starch content of the grain (by 0.1-0.46% in 2011-2013) compared to the control (without foliar fertilization). The highest starch content in the grain of the studied maize hybrids (70.92-76.72% and 71.45-76.72%) was provided by foliar fertilization with microfertilizers Ecolist Mono Zinc and Rostock corn. A decrease in the starch content was observed during crop treatment with the plant growth regulator Vimpel in the phase of 5-7 corn leaves on hybrids DKS 3420 by 0.36%, Pereyaslavsky 230SV by 0.11% and DKS 3871 by 0.5%, respectively.
