“…is a widespread wheat pest, particularly numerous in the steppe zone of North-Eastern Kazakhstan. Wheat was damaged by both adult thrips and their larvae (Ivanchenko and Shevyakhova, 2022;Zhichkina et al, 2021;2023). Adult insects cause damage during the period of wheat stem elongation-heading.…”

The article is devoted to the study of spring wheat varieties cultivated in the steppe area of North-Eastern Kazakhstan and their resistance to the main pests. The dynamics of the number and phenology of spring wheat phytophages were investigated in relation to the varietal and climatic characteristics of agricultural production. Modern spring wheat varieties' resistance to the main pests was evaluated in the area of study for the first time. In the course of studying the harmfulness of pest complexes for the studied varieties, three-point mobile scales were used for the first time. They made it possible to identify patterns of varieties damage according to different pest numbers. Reliable differences of nine varieties with respect to the uptake of spring wheat by major pests, as well as their harmfulness, were established. 'Triso', 'Likamero', and 'Kurier' varieties with group resistance to them were identified. An economic evaluation of resistant spring wheat varieties was provided. The study used a three-point evaluation method with moving score limits to identify spring wheat varieties that were settled and damaged by pests. It enables the estimation of varieties with different background densities of insects and the comparison of data from different soil-climatic zones. The analysis of the obtained results confirms the high economic efficiency of pest-resistant varieties cultivation and the role of these varieties in the phytosanitary stabilization of agrobiocenoses and environmental protection. The results of the research could be used in the zoning of spring wheat varieties. Identified cultivars with group-based pest resistance might be used as donors for new breeding varieties.

The object of research is the economic relations of agricultural producers in the production of spring wheat grain. The purpose of the article is to formulate the distinctive features of the business mechanism for growing spring wheat and its improvement. The main tasks implemented in the study include: - to identify the elements of the business mechanism for growing spring wheat; - to determine its main aspects that determine the level of economic effect of growing spring wheat; - assess the level and structure of state assistance in the cultivation of spring wheat at the regional level. As a result of the research, the main organizational and economic aspects of spring wheat cultivation in the Samara region were identified. In recent years, the volume of spring wheat production in the region has grown due to an increase in the sown area and yield, while the gross harvest in 2019 amounted to 245.8 thousand tons. The spring wheat cultivation efficiency is significantly influenced by the basic tillage type, the costs of which can be up to 20% in the structure of production costs. The option with fine processing by 10-12 cm showed the greatest efficiency. The profitability of this option was 87%. State support at the regional level plays a significant role in shaping the profitability of spring wheat cultivation.

The development of the grain industry determines the food security level in Russia. Grain is a food product for humans, animal feed, raw material for industries. The research was carried out in 2018-2019 in the Samara region conditions. The research purpose is to determine the effectiveness of nitrogen fertilizing in the winter wheat cultivation. The research tasks included: - to identify the effect of nitrogen fertilization on the winter wheat yield; - to calculate the economic efficiency of using nitrogen fertilizers for winter wheat. As a result of the studies, it was found that in the variant without the use of nitrogen fertilization, the yield of winter wheat was 21.8 cwt/ha and was the lowest. In variants with the top-dressing use, the yield varied from 22.7 cwt/ha, when used as top-dressing of ammonium nitrate to 24.1 cwt/ha when used as an additional fertilizing of KASS. The increase in yield from fertilizing with nitrogen varied from 0.9 cwt/ha (4.1%) to 2.3 cwt/ha (10.6%). From an economic viewpoint, the most effective option was the application of nitrogen fertilizers KASSA, which made it possible to obtain an economic effect of 1240.95 rubles, while reducing the cost by 165.6-628 rubles/cwt and increasing the profitability level by 57.5-66.1%. The results obtained make it possible to recommend the production of the use of liquid forms of nitrogen fertilizers for feeding winter wheat, contributing to an increase in the profitability of crop cultivation.
