“…According to Golubev et al [19], sweet sorghum easily tolerates summer drought, and after a long period without precipitation, it is able to continue growth and development without any loss in biomass. In addition, sweet sorghum during the growing season economically consumes soil moisture for the formation of vegetative and generative organs.…”

This study aimed to determine the effects of biologically active substances and nitrogenphosphorus fertilizers on the yield of sugar sorghum (Sorghum bicolor L.) grown in southern Kazakhstan. A three-year field experiment was conducted using a factorial design with the sorghum variety 'Kazakhstanskoe 20'. Three fertilizer treatments (control, N30P30, N60P60, N90P90 kg/ha) were combined with three seed treatments (Celeste Top, Gumi 20, Potassium Humate). Sorghum was harvested at the wax ripeness stage. Analysis of variance was used to analyze the data. Fertilizer dose, seed treatments, and their interaction significantly increased sorghum green mass yield compared to the control. The highest yields (18.0-19.3 t/ha) resulted from combining N90P90 fertilization with seed treatments. Celeste Top and Gumi 20 increased yields by 1.6-4.1 t/ha across fertilizer doses, while Potassium Humate had the greatest effect (increase of 2.7-5.4 t/ha). The integrated use of biologically active seed treatments and moderate to high doses of nitrogen-phosphorus fertilizers can substantially increase the productivity of sugar sorghum grown in southern Kazakhstan. These findings provide agronomic strategies to improve sorghum yields under arid conditions.

“…The objects of research were fungicides of inorganic copper compounds: on an apple-tree based on copper hydroxide -Champ DP, VDG (576 g/l) and Koside 2000, VDG (350 g/kg), standard; on the drain, a new innovative mix-fungicide Terpen C, KS (400 g/l copper hydroxide); Cuproxat, KS (345 g/l of copper sulfate tribasic) and Abiga-Peak, VS (400 g/l of copper oxychloride), standard. The work used the methods of laboratory analyzes, setting up field experiments according to generally accepted and adapted techniques [13]. Field experiments were carried out: on an apple tree -on a stationary site of ZAO OPH "Tsentralnoye", Champion variety, 2010 planting, stock M 9, planting pattern 4.5 x 1.2 m, tree height 2.0-2.5 m; on the drain -in the growing station NCFSCHVW, variety Kabardinskaya early, 2001 planting, planting scheme 3 x 2 m, tree height 2.5-3.0 m. In both experiments, the flow rate of the working fluid -at the rate of 1000 l/ha, repeatability -three times.…”

The effectiveness of inorganic copper compounds on apple and plum trees under extreme weather conditions in 2018-2020 has been evaluated. Fungicides Koside 2000, VDG and Champ DP, VDG controlled apple scab by 98-99.6%, preparations Cuproxat, KS and Terpen C, KS blocked plum clotterosporiasis by 85.1-100%. The use of these fungicides did not have a negative effect on the biochemical composition of the fruit. Significant differences between the variants were found in the content of potassium and calcium cations, on the drain, in addition, in the content of sodium and magnesium cations. The possibility of biologization of protection technologies has been established: the use of the fungicide Champ DP, VDG on the apple tree, the replacement of Abiga-Peak, VS on the drain with preparations with lower consumption rates – Kuproksat, KS and Terpen C, KS. This ensures a reduction in the pesticide load on the environment, a decrease in the risk of resistance and the damaging effect of fungicides on trees weakened by stress.

“…The technological process of seed material sowing can be divided into several stages (Fig. 2.): 1-fall of seeds on the surface of the sowing cone, 2-fall of seeds into the seed duct, 3transport of seeds through the seed duct to the plowshare group [4]. When considering the first stage of seed movement, the driving force will be the friction force [5] of seeds on the surface of the cone ( internal friction force of seeds located above the sown seed is neglected at this stage) (Fig.…”

In this paper, we consider the study of the process of seed movement in the seed duct and the impact on the operation of a multi-level seeding system. Mathematical models of the movement of the seed material from the seeder to the plowshare group along the seed line are obtained. To a greater extent, the movement time is affected by the weight of the sown portion and the initial speed of the seeds when falling from the seeder. Also, in straight sections, the time depends on the geometric parameters of the seed line. In the future, the formula of the complete transfer of seeds from the seeder to the plowshare group will allow you to adjust the mode of adjusting the response time of the dosing system on a self-propelled seeder with a multi-level seeding system.
