“…The main reason is the violation of agricultural technologies, extremely low fertilization and aridity of the climate. More severe weather conditions in recent years in the Omsk region developed in the five-year period 1996-2000, when the yield of grain crops in most areas did not exceed 1.20-1.50 t/ha (Yushkevich et al, 2021). It is established that the influence of hydrothermal conditions in the formation of grain yield in arid conditions is unequal.…”

“…In this regard, in order to increase the effectiveness of agricultural technologies in arid agricultural landscapes, it is necessary to use moisture storage techniques (the optimal share of the steam field in the structure of arable land is up to 16-18%, mechanized snow retention UVS -9.0, stubble of increased cut, the use of combing harvesters, sowing of wings, mulching of soil, improvement of technical means, etc.) [11,13,14].…”

In the arid agricultural landscapes of Western Siberia, the productivity of leading grain crops is determined by adaptive agrotechnology, the use of intensification tools and hydrothermal conditions. The relatively low (up to 1.40-1.70 t/ha) and unstable yield of grain crops is mainly due to the limited use of fertilizers (up to 20 kg/ha), the aridity of the climate. Long-term studies have established that in the southern forest-steppe agricultural landscapes, precipitation of all periods of the year, except for spring, has an impact on grain productivity. Autumn moisture reserves determine the yield of spring wheat after its corn predecessor by 51% in general, up to 21% for steam, and only 13% for barley. The conjugacy of spring soil moisture is higher on wheat, on flat-cutting processing than on plowing, on intensive agrotechnology. The most significant combination of spring moisture reserves and summer precipitation (June-1st decade of July). The dependence of wheat yield after steam reaches a high conjugacy (r=0.77-0.84), after corn – from medium to strong (up to 59-71%). The correlation of yield with the temperature regime during the growing season is negative. The conjugacy with the value of GTK is more pronounced after the corn precursor – 46%, steam – up to 30%, barley only 8%, the greatest dependence was revealed with the Coefficient of dryness. The predicted yield level of high–quality grain with complex chemicalization and soil protection treatment with average long-term hydrothermal parameters on wheat after the corn precursor reaches 2.8 t/ha with a probability of up to 76%, and 3.4 t/ha for steam. To optimize the water regime, it is necessary to use additional moisture-accumulating agricultural techniques.

“…Сибирская пшеница, благодаря почвенно-климатическим особенностям региона, а также в силу сортовой специфики, отличается высокими технологическими свой ствами. В то же время средняя урожайность пшеницы в регионе находится на уровне 1,50…1,80 т/га и менее, что связано с засушливостью климата в последние годы, нарушением зональных агротехнологий, ограниченным применением удобрений и другими факторами [1]. Одним из ведущих приемов, обеспечивающих высокую продуктивность агроценозов и получение высококачественной продукции, является применение удобрений [2][3][4].…”

The effectiveness of fractional application of nitrogen fertilizers in cultivation of spring common wheat was studied in the conditions of the Omsk Irtysh region on meadow-chernozem medium-sized medium-humus heavy loamy soil. The research object was spring common wheat (Triticum aestivum L.) cv. Melodiya. The purpose of the research was to establish the effectiveness of fractional application of nitrogen fertilizers depending on the level of labile phosphorus in meadow-chernozem soil on yield and grain quality of spring common wheat in the conditions of the Omsk Irtysh region. The field experiment had three factors (242): Factor A phosphorus background: 1. No fertilizers; 2. Application of P30 a. i./ha; factor B main application of ammonium nitrate in increasing doses: 0, N30, N45, N60; factor C foliar feeding with ammonium nitrate and carbamide at a dose of N30: 1. Once in heading stage; 2. Twice in heading stage and milky ripeness. It was found that the most effective was main application of nitrogen-p hosphorus fertilizers in doses of N3045P30; crop productivity in these variants increases by 4048 % in comparison with the nonfertilized variants due to the gain in 1000-seed weight (r = 0.400.42), productive stooling (r = 0.83). The agronomic profitableness of one kg of a. i./ha applied fertilizers in these variants was 21.5 and 19.9 kg of grain with 7.5 and 6.1 kg increase in protein content, respectively. Late foliar sprayings, regardless of their number, did not increase crop productivity and quality of wheat grain. Thus, fractional application of nitrogen fertilizers in years with insufficient moisture levels (hydrothermal index 0.60.7) is not effective.
