“…A trend towards higher proportions of cereal-dominated CSs has been observed, which can increase the risk of yield losses (e.g. Berzsenyi et al ., 2000; Babulicova, 2014; Babulicova and Dyulgerova, 2018; Nielsen and Vigil, 2018), inter alia, due to higher weed pressure or soil-borne diseases (Petersen et al ., 2010).…”

One of the major challenges in agriculture is how climate change influences crop production, for different environmental (soil type, topography, groundwater depth, etc.) and agronomic management conditions. Through systems modelling, this study aims to quantify the impact of future climate on yield risk of winter wheat for two common soil types of Eastern Denmark. The agro-ecosystem model DAISY was used to simulate arable, conventional cropping systems (CSs) and the study focused on the three main management factors: cropping sequence, usage of catch crops and cereal straw management. For the case region of Eastern Denmark, the future yield risk of wheat does not necessarily increase under climate change mainly due to lower water stress in the projections; rather, it depends on appropriate management and each CS design. Major management factors affecting the yield risk of wheat were N supply and the amount of organic material added during rotations. If a CS is characterized by straw removal and no catch crop within the rotation, an increased wheat yield risk must be expected in the future. In contrast, more favourable CSs, including catch crops and straw incorporation, maintain their capacity and result in a decreasing yield risk over time. Higher soil organic matter content, higher net nitrogen mineralization rate and higher soil organic nitrogen content were the main underlying causes for these positive effects. Furthermore, the simulation results showed better N recycling and reduced nitrate leaching for the more favourable CSs, which provide benefits for environment-friendly and sustainable crop production.

“…Ефективність добрив коливається залежно від клімату зон і погодних умов вегетації (Lykhochvor & Petrychenko, 2010). За регулярного застосування високих норм мінеральних добрив, окрім високих врожаїв, у ґрунтах створюється запас поживних речовин (N, P, K, Ca, Mg та інші) (Baliuk et al, 2012;Veha, 2015;Zaiets, 2018;Lopushniak & Veha, 2015;Babulicová & Dyulgerova, 2018).…”

The use of urease inhibitors with nitrogen fertilizers is gaining relevance. There was a need to substantiate the expediency of combining these technology elements when growing winter barley. We conducted field experiments at the Lviv National Environmental University in the Banded Forest of the Western Forest Steppe conditions in 2020–2022. Our research goal is to describe the interaction of mineral fertilizers with the N-LokTM brand inhibitor, which restrains the formation of nitrates but improves the agrochemical parameters of the soil. This had a positive effect on the yield of winter barley. The soil is a dark gray forest gilded light loam with low humus. We used traditional methods of field research and standardized methods of laboratory analyses. The nitrogen fertilization system N97(NH4NO3) during vegetation restoration + N-LokTM (before sowing or during vegetation restoration) on the background of N23P60K60 ensured the initial content of easily hydrolyzable nitrogen in the arable layer of 132–136 mg/kg of soil. Applying N97(NH4NO3) + N-LokTM to winter barley during the restoration of vegetation on the background of N23P60K60 under plowing provided the highest yield in the experiment of 7.69 t/ha on average for 2020–2022. The average grain increase relative to the N97(NH4NO3) control (vegetation restoration) on the N23P60K60 background was 1.08 t/ha. On the other hand, applying N97(NH4NO3) during the restoration of vegetation + N-LokTM in autumn before sowing on the same background contributed to a more significant yield increase – by 1.26 t/ha only in 2021. The absence of a phosphorus-potassium background in the winter barley fertilization system reduced the crop yield by 0.11–0.44 t/ha. The significant importance of mineral fertilizers for obtaining high grain harvests, especially in less good years, is proven by the established high correlation coefficients of the parameters of available compounds of nitrogen, phosphorus, and potassium at the start of the growing season with the harvest in 2020–2021. The regression 3D model of winter barley grain yield under the influence of the synergistic effect of nitrogen fertilization rates and the resulting enrichment of the soil with easily hydrolyzable nitrogen illustrates the importance of fertilizers for increasing the fertility of the dark-gray podzolized light loam soil in Pasmovy Pobuzhzhia of the Western Forest Steppe.

Львівський національний університет природокористування Наведено результати трирічного дослідження системи удобрення ячменю озимого з поєднанням стабілізатора нітратів у темно-сірому опідзоленому ґрунті Пасмового Побужжя Лісостепу Західного. Встановлено, препарат N-Lok Mакс, як інгібітор уреази, мав істотний вплив на формування врожаю та різну ефективність залежно від погодних умов застосування, форм і строків внесення азотних добрив. Завдяки сповільненню утворення нітратів вдалося отримати найвищий врожай зерна на високих фонах азотних та за помірних норм фосфорно-калійних добрив. Ключові слова: азот, висота ячменю, розвиток колоса, озерненість, стабілізатор азоту, врожай зерна Вступ. Поширення культури озимого ячменю в Україні потребує диференціального -зонального підходу до мінерального удобрення і, зокрема, азотного [5, 7, 10]. Азот стимулює ростові процеси у ключові фази онтогенезувід кущення то колосіння, підвищуючи інтенсивність дихання і швидкість обміну речовин. Проте, надлишок азоту водночас спричинює ризик вилягання стеблестою за надмірного удобрення та несприятливої погоди [6, 19, 20, 28]. Табл. 2.
