“…The ease of use of the drone, which anyone can handle with a little training. The use of an unmanned complex allows, in the presence of the same equipment (tractors, seeders, combines), to increase the yield by up to 20% and reduce costs by up to 15% [26][27][28][29][30].…”

The article deals with the issue of economic efficiency of the use of drones in agricultural production. There is an opinion about their inefficiency, which is refuted by the study. The purpose of the study is to determine the effectiveness of the use of agricultural drones (using the example of U-30L-6 (BROUAV) in comparison with other technological options. The use of agricultural drones allows not only to reduce the cost of manufactured products, but also to increase crop yields by reducing losses during cultivation, as the number of passes of wheeled vehicles across the field during the growing season is reduced. Among the options considered (trailed sprayer, self-propelled sprayer, agrodrone), the use of copters took the second place in terms of production costs. But due to a decrease in the spraying rate and losses from trampling, the economic effect of using agricultural drones is the highest (3417.34 rubles/ha), which is more than twice as high as when using a self-propelled sprayer.

“…The resulting models can be used to predict the dynamics of sown areas devoted to sugar beet in the regions of Russia [33][34][35][36][37][38][39]. So, for example, in 2023 the sown area of the Penza region should be 68.3 thousand ha, in 2024 -60.9 thousand ha; in the Krasnodar region in 2013, the area will amount to 231.1 thousand ha, in 2024 -182.9 thousand ha; in general, in the Russian Federation 1112.5 thousand ha and 889.9 thousand ha, respectively.…”

The article analyzes the dynamics of indicators characterizing the production of sugar beets in Russia. The Krasnodar region, the Penza region and the Russian Federation as a whole were chosen as the object of study, the sown areas, the gross harvest and the yield of sugar beet were chosen as the subject of the study, and the period from 2005 to 2022 was chosen as the time interval. At the first step of the work, a primary analysis of the studied dynamic series is carried out, which showed a stable growth of indicators with a maximum jump in 2010. Next, regressions are constructed that describe long-term trends in the development of processes, for which, in most cases, quadratic functions are chosen. The next step is modeling the cyclical component and developing multiplicative trend-seasonal models, the error of which was 7.4% -13.8%. As a result of the study, a forecast for the development of the industry for 2023-2024 is built.

“…It was established that their harmfulness is 1.71 mg of yield per year from the feeding of one species [SAGITOV, ISMUKHAMBETOV 2004]. In addition, plants grown from seeds damaged by the wheat thrips will be more susceptible to abiotic and biotic stress factors, and, consequently, this will reduce their productivity [ZHICHKINA 2014].…”

To improve plant resistance to pests, we analysed the impact of various agronomic practices on the number and species diversity of pests in the crops of spring wheat varieties of foreign and Kazakhstan breeding in North-Eastern Kazakhstan.The intensive development of agriculture, resulting in the new technological flow processes of wheat growing, the sowing of foreign varieties not previously cultivated under local conditions, and climate change contribute to the formation of new food chains in agrocenoses. These new food chains require the monitoring of plant-feeding species with the help of ecological approaches and techniques.Efficient protection of crops with plant feeders requires constant updating on the phytosanitary in agrocenoses. Information on phytosanitary monitoring previously carried out in the region is not available, so it became necessary to collect data and analyse the number and species composition of wheat pests, considering new foreign varieties and cultivation technology practices.The research was carried out in 2021 in typical agricultural organisations of the North-Eastern regions of Kazakhstan with different preceding crops. The vegetation period was characterised by high atmospheric temperatures and a lack of moisture in the soil in spring and summer, contributing to decreasing of plant turgor and damage resistance.Early sowing of the 'Triso' wheat variety was affected by high temperatures and lack of soil moisture in the initial stage of development, which delayed its growth and made it more susceptible to pest damage. The other varieties were sown in optimal dates recommended by regional scientific institutions.
