The preservation of productive moisture reserves and the rational use of soil fertility, as well as its reproduction, remains a necessary condition for optimizing agricultural landscapes and increasing the productivity of agrocenoses. Improving the technology of cultivation of agricultural crops plays an important role in increasing the sustainability and yield of cultural cenosis. Precursors and crop rotation remain one of the most important elements in crop cultivation technologies. Despite the importance of these elements, there is a weakening of attention to the introduction and development of crop rotations, both in our republic and in the whole country. The studies conducted over 23 years have shown the influence of precursors in crop rotation on the phosphate regime of gray forest soil in the conditions of the Ancestral region of the Republic of Tatarstan. Thus, when placing rye after peas on grain, there was an increase in the content of mobile phosphorus during the growing season against the average background of fertilizers applied (the planned yield level is 2.5 grains/ha). The influence of various precursors on the incidence and development of the most common diseases of winter rye has been established; Pucciniarecondite Robergeex Desmas. f.sp. secales, Bipolarissorokiniana Shoemaker.

An analysis was made of the productivity of Black-and-White cows, originating from 60 sires of different lines, as well as those evaluated by the kappa-casein gene, which were used in Krasny Vostok Agro JSC. It has been established that cows of the R. Sovering line are characterized by the highest rates of economically useful traits, with an advantage in milk yield by 65-281 kg, in live weight by 6-24 kg, in terms of milk production index by 1-8 kg, in terms of milk yield by 0.01-0.12 kg/min. The worst indicators of productivity were found in animals of the Governer line. In general, interstrain differences are not high and productive indicators are within the normal range. When analyzing the milk productivity of the daughters of sires, carriers of various kappa-casein genotypes, it was revealed that cows of fathers with the AA genotype for kappa-casein have higher quantitative indicators of milk productivity and significantly (P<0.05-0.001) exceed the CSN3 AB and CSN3 EE by milk yield per 254-715 kg, by the amount of milk fat by 8.5-23.9 kg, by the amount of milk protein by 9.2-27.2 kg. At the same time, daughters of bulls with the CSN3 AA genotype are characterized by the maximum proportion of milk protein in milk, with an advantage over other groups by 0.03-0.12% (P<0.05-0.001). The CSN3 EE group is characterized by a high fat content in milk (4.11%) and exceeds other groups by 0.07-0.10% (P<0.01-0.001).

This is due to continuity, endurance, the ability to work under overload conditions and the exclusion of the human factor. In recent years, there has been a revolutionary leap in the development of UAVs, which made it possible to divide this market segment into completely different price categories. The increase in the use of UAVs has made this product really in demand and was able to introduce it into various areas of life. This also applies to geodetic measurements. Photogrammetry methods began to work closely with methods of easy-to-control unmanned aerial vehicles. But at the same time, the demand for filming equipment is growing, the pricing policy of which sometimes considerably exceeds the cost of the aircraft itself, which complicates photogrammetric work. This aspect has led to research on the possibility of using inexpensive non-professional cameras on UAVs for photogrammetry, due to obtaining accurate measurements. For such cameras, there is such a thing as calibration, which includes the definition of interior orientation elements. This article discusses the use of non-metric cameras on UAVs in order to reduce the cost of work to monitor agricultural land. The following materials were used as initial data in this work: test images from the UAV at the test site; software such as SAS.Planet, MatLAb, MdCockpit V2.6.2.6, PHOTOMOD. To perform this work, the following equipment was used: unmanned aerial vehicle; non-metric digital camera.

The studies were carried out in 2020–2021. at the Department of General Agriculture, Plant Protection and Breeding of the Institute of Agrobiotechnologies and Land Use.

A comparative analysis of the change in the weight of 1000 grains of varieties under the influence of the conditions of a dry 2021 showed that the largest-grained genotypes with a weight of more than 54 g of selection from Germany, France, and the National Academy of Sciences of Belarus in drought conditions reduce grain filling by 7-17%. The varieties of local selection Endan and Tevkech formed larger grains in the dry year 2021, which may be due to a longer grain filling due to the increased drought resistance of plants of these varieties.
