The effect of synthesized organic compounds of 6-hydroxy-2,2,4-trimethyl-1,2-dihydroquinoline, its derivatives, and hydrogenated analogs on the height of seedlings of ornamental woody plants was studied. The height of seedlings as a morphometric parameter was measured 7 months after the start of the experiment. The pre-sowing seed treatment of Rhododendron ledebourii and Rhododendron smirnowii, with the studied compounds, demonstrated that dihydro- and tetrahydroquinoline with the concentration of 0.1% proved to be the most efficient. Dihydroquinolines at concentrations of 0.05 and 0.1% proved to have the strongest effect. Dihydroquinolines for perennial woody plants are more effective, then tetrahydroquinolines. The most efficient synthesized chemical compounds for Rhododendron contain benzoyl substitute. For Rh. ledebourii and Rh. smirnowii the most effective are the same synthesized chemical compounds: 6-hydroxy-2,2,4-trimethyl-1,2,3,4-tetrahydroquinoline, 6-hydroxy-2,2,4-trimethyl-1,2-dihydroquinoline, and 1-benzoyl-6-hydroxy-2,2,4-trimethyl-1,2- dihydroquinoline with concentrations of 0.01, 0.05, and 0.1%. These compounds, when applied with the presowing seed treatment of Rh. ledebourii and Rh. smirnowii, result in an increase in the height of the seedlings by 3.6-89.3% and 14.3-57.1%, respectively. The effect of synthesized chemical compounds of 6-hydroxy-2,2,4-trimethyl-1,2-dihydroquinoline and its hydrogenated analog on woody plants of the same genus is not speciesspecific. It is suggested using the compounds of 6-hydroxy-2,2,4-trimethyl-1,2-dihydroquinoline, its derivatives, and hydrogenated analogs as growth stimulators for Rhododendron. The compounds of the quinoline series were tested for genotoxicity by the cytological method in the model object (Betula pendula) and recognized as environmentally friendly. The cytogenetic responses for Betula pendula and Rhododendron are identical, so positive compounds influence for Betula pendula cells because of increased metabolic activity means the same for Rhododendron. Therefore, synthesized organic compounds can be recommended as effective growth stimulators.

It is investigated the effect of synthesized organic compounds of 6-hydroxy-2,2,4-trimethyl-1,2- dihydroquinoline, its derivatives, and hydrogenated analogs. These compounds affected the height of seedlings when they were used for pre-sowing seed treatment of the following ornamental plants: annual ornamental grass – scarlet sage (Salvia splendens) and woody plant – yellow rhododendron (Rhododendron luteum). Prior to the sprouting process, the seeds of Rh. luteum and S. splendens were soaked in water solutions of compounds with concentrations of 0.01%, 0.05%, and 0.1% for 18 hours. Dihydro- and tetrahydroquinolines with a concentration of 0.05% proved to be the most effective for both plants. For Rhododendron luteum, the compounds of 6-hydroxy-2,2,4-trimethyl-1,2-dihydroquinoline, its derivatives, and hydrogenated analogs with a concentration of 0.1% proved to be the most effective. Dihydroquinolines at concentrations of 0.05 and 0.1% proved to have the strongest effect when applied to the studied perennial woody plant (Rhododendron luteum). Dihydroquinoline at the concentration of 0.05% also proved to be effective when applied to the annual grass (Salvia splendens). For annual S. splendens, tetrahydroquinoline at concentrations of 0.01 and 0.05% appeared to be the most effective. The pre-sowing seed treatment of grass Salvia splendens and woody plant Rhododendron luteum with the studied compounds demonstrated that their effect on the height of the seedlings is species-specific. The pre-sowing seed treatment of Rh. luteum and S. splendens allows increasing the height of the seedlings by 3-61 % and 17-25 %, respectively. It is suggested using the compounds of 6-hydroxy-2,2,4- trimethyl-1,2-dihydroquinoline, its derivatives, and hydrogenated analogs as effective growth stimulators for ornamental grasses and woody plants

In conditions of climate change, when temperature and precipitation fluctuations occur more and more frequently during the growing season, it is necessary to obtain high quality seedlings with "immunity" to various stress factors, including high weediness, the damage from which is associated with a decrease in yield (by 25 -35%) and with a deterioration in the quality of agricultural products. Due to the imbalance in production technology, seedlings are often weakened, overgrown, with a low yield per unit area and survival rate in the field. One of the solutions to this problem is the use of PP for pre-sowing seed treatment to increase the competitiveness of seedlings in the field.

Seed of Leucaena glauca (L.) Benth. germinates slowly, and irregularly unless treated before sowing to render the testa permeable to water. Treatment with sulphuric acid is effective but inconvenient to use. Experiments with hot water over a range of temperature and time are described. An effective treatment was to immerse the seed in water at 80�Cfor two minutes. After this treatment seed can be dried rapidly and stored before sowing. Seed treated in this way has retained full viability for 15 months.

The article presents an analysis of the determination of the effectiveness of mineral and organic fertilizers on the yield of winter wheat grain. The studies were carried out in 2017–2020 in the Rostov region on the southern chernozem. The object of research was the Doneko winter wheat variety. The predecessor is corn for grain. Ammonium nitrate, ANP fertilizer (16-16-16) and urea were used as mineral fertilizers, which were applied in the fertilization system of winter wheat and acted as a background option in the experimental scheme. ANP fertilizer (16-16-16) was introduced when sowing winter wheat, ammonium nitrate - scattered over thawed-frozen soil and carbamide in the heading phase by foliar method. Organomineral fertilizers were represented by the following types: Ruther, Leili 2000, Siamino Pro, Gumiful Pro, Soft Guard and Double Wine MKR (monocaliphosphate) produced by Biokepharm (Switzerland). The raw material for the production of organomineral fertilizers was the algae of the warm seas Laminaria. In the field experiment, the options for the joint application of foliar application and pre-sowing seed treatment with organomineral fertilizers were also studied. The control was the option without mineral fertilizers and the option with the background of the use of mineral fertilizers (farm fertilization system). It was found out that the use of organic fertilizers Ruter (0.5 or 0.25 l / t) and Leyli (0.25 l / t) for seed treatment before sowing, the use of Soft Guard (0.2 l / ha) and Gumiful Pro ( 0.2 l / ha) in the spring tillering phase and in the flag leaf phase against the background of sowing nitroammophoska at a dose of N32P32K32, random fertilizing on thawed-frozen soil with ammonium nitrate at a dose of N40 and the use of carbamide in the heading phase at a dose of N20 increased grain yield on average for 2018–2020 compared with the control (fertilization system of the farm) by 0.73 t / ha, or 23.0%. The maximum yield increase from the root-forming agent Ruther, used for pre-sowing seed treatment, reached 0.36 t / g, or 11.3%.
