Purpose: the aim of the article is to evaluate supply chain resilience strategies adopted by an industrial cluster to cope with the lack of critical materials originated from the Ukraine crisis Design/methodology/approach: the study analyzes historical time series between the 2014 and 2022 Ukrainian crisis and assess import concentration adapting the HHI Index methodology to evaluate critical supply chains. Findings: despite a lack of a coherent supply chain resilience strategy, empirical data imply the self-emergence of adaptive behaviors within a prototypical industrial cluster. Originality/value: These results could suggest the intrinsic value in terms of supply chain resilience of strong socio-economic networks and addresses new research scenarios.

Background: With the emergence of supply chain management as a key strategic function in the agri-food sector, a lot of research has been conducted to find ways to improve the performance and sustainability of agri-food supply chains. The Triple-A Supply Chain concept, which refers to the agility, adaptability, and alignment of the supply chains, has been a field of study for various researchers aiming at shaping meaningful and sustainable competitive advantages for businesses and organizations in various sectors. Over the years, alternative, complementary, or upgraded versions of this approach have been proposed, such as the “New AAA Supply Chain”, which describes the renewed Triple-A Supply Chain model based on Super-Agility, Architectural Adaptability, and Ecosystem Alignment, and the “Triple A & R” framework, which refers to Agility for Robustness, Adaptability, and Resilience, and Re-Alignment. Methods: This paper presents the results of a selective study of the bibliography considering the Triple-A Supply Chain model, the “New AAA Supply Chain” model and the “Triple A & R” framework. These frameworks are analyzed and compared with each other considering their principles, and their implementation in the agri-food sector is researched. The scope of this study is to analyze the potential of the application and suitability of these frameworks in agri-food supply chains, having considered the particularities of the sector. Results: Examining the models concerning the evolution of the Triple-A Supply Chain paradigm, it is evident that they differ from each other, as they approach supply chain management from different viewpoints. Conclusions: The potential of application of various models originating from the Triple-A Supply Chain paradigm was examined in the case of the agri-food sector considering product nature, sustainability, and investment cost as the factors affecting it. These frameworks could partially find application in the agri-food sector, as some of their guidelines promote the increase of the agri-food supply chain effectiveness.

В статье приведены теоретическое обобщение и новое решение научной задачи, которая заключается в научном обосновании и разработке агротехнологических мероприятий повышения зерновой продуктивности растений пшеницы озимой с учетом морфобиологических особенностей сорта, его реакции на применение микробиологических препаратов с целью повышения эффективности выращивания и стабилизации валовых сборов зерна в регионе. Установлено, что инокуляция семян микробиологическими препаратами положительно сказалась не только на формировании биометрических показателей растений пшеницы озимой, но и улучшало физиологические процессы, такие как накопление хлорофилла в листьях. Условия осенней вегетации растений озимых в годы проведения исследований способствовали наращиванию содержания хлорофилла в вегетативных частях растений. Так, на время прекращения осенней вегетации все варианты, где применяли инокуляцию семян обеспечили увеличение содержания хлорофилла по сравнению с контролем от 0,3 мг/г а.с.в. до 0,6 мг/г а.с.в. Среди вариантов выделились те, где к препарату Меланориз добавлялись ГумиФренд или ХелпРост. Исследованиями доказано, что использование микробиологических препаратов в технологиях выращивания озимой пшеницы способствует усилению поступления питательных веществ к растениям, стимулирующим развитие растений в течение вегетации, и, как следствие, повышает показатели структуры урожая. Наряду с вариантами, где использовали инокуляцию семян, варианты с опрыскиванием посевов также повлияли на длину колоса обеспечив прибавку к контрольному варианту на 4,1%, за счет опрыскивания посевов в фазу кущения и на 6,9% при опрыскивании посевов в фазу флагового листа препаратом ГумиФренд. Установлено, что за годы проведения исследований, наиболее существенная прибавка урожайности была при инокуляции семян препаратом Меланориз (12,5%). В результате многолетних исследований усовершенствованы существующие приемы выращивания озимой пшеницы за счет внедрения новых агротехнических мероприятий, которые позволяют в условиях восточной части Северной Степи полнее реализовывать генетические особенности нового сорта озимой пшеницы

The article presents a theoretical generalization and a new solution to a scientific problem, which consists in the scientific substantiation and development of agrotechnological measures to increase the grain productivity of winter wheat plants, taking into account the morphobiological characteristics of the variety, its response to the use of microbiological preparations in order to increase the efficiency of cultivation and stabilize the gross grain yield in the region. It was found that the inoculation of seeds with microbiological preparations had a positive effect not only on the formation of biometric indicators of winter wheat plants, but also improved physiological processes, such as the accumulation of chlorophyll in the leaves. The conditions of autumn vegetation of winter crops during the years of research contributed to an increase in the content of chlorophyll in the vegetative parts of plants. So, at the time of the termination of the autumn vegetation, all variants where seed inoculation was used provided an increase in the chlorophyll content in comparison with the control from 0.3 mg/g up to 0.6 mg/g. Among the options stood out those where GumiFrend or HelpRost were added to the Melanoriz. Studies have shown that the use of microbiological preparations in winter wheat cultivation technologies enhances the supply of nutrients to plants that stimulate plant development during the growing season, and, as a result, increases the yield structure indicators. Along with the options where seed inoculation was used, the options with spraying crops also influenced the ear length, providing an increase to the control option by 4.1%, due to spraying crops in the tillering phase and by 6.9% when spraying crops in the flag leaf phase with the GumiFrend. It was found that over the years of research, the most significant increase in yield was when seeds were inoculated with Melanoriz (12.5%). As a result of many years of research, the existing methods of growing winter wheat have been improved through the introduction of new agrotechnical measures, which make it possible to more fully realize the genetic characteristics of a new variety of winter wheat in the conditions of the eastern part of the Northern Steppe.
