The research was carried out with 6 plum cultivars as: 'Piteștean', 'Cacanska Najbolia', 'Empresso', 'Stanley', 'Blue Free' and 'President (C) ', grafted on the rootstock Prunus cerasifera Mhr, planting distance 5.0x3.0 m, crown shape mixed pyramid with high volume. During the research, the diameter and growth of the trunk, the TCSA, the phenological phases of the fruiting organs during 2025 year, the morphological parameters of the fruit and seeds, the number of fruits, their average weight, the fruit yield per tree, per unit area, as well as per unit TCSA was studied. It was established that the studied cultivars had a favourable condition for growth and fruiting in the northern part of the country. Lower production, of 11.7 t/ha, was registered for the Blue Free variety, and higher production for the cultivars 'Piteștean' (25.4 t/ha) and 'Cacanska Najbolia' (27.6 t/ha). The other cultivars registered average values (18.3-21.7 t/ha), characteristic of intensive plum plantations. The ripening period for the studied cultivars was distributed over 45 days of harvesting. It has been established, that the biological characteristics of the variety, the climatic conditions and the age of the plantation have a direct influence on the number of fruits per tree, the average weight of plums, the fruit production per tree, per hectare and per unit of trunk cross-sectional area.

Sustainable livestock production is crucial for ensuring food security, sustaining natural ecosystems, and supporting rural livelihoods. In Moldova, the livestock sector faces challenges such as climate variability, limited forage availability, and the need to reduce greenhouse gas emissions. This review synthesizes the current literature on strategies for developing resilient livestock systems, with a focus on efficient feed management. Innovative approaches considered include the cultivation of alternative forage species, optimization of feed use, and the adoption of environmentally friendly production practices. Policy frameworks, research initiatives, and technological advancements relevant to sustainable livestock development were also analysed. Evidence indicates that alternative forage species and optimized feed strategies can enhance livestock productivity while reducing environmental impact. When combined with supportive policies and technological innovations, these environmentally friendly practices improve both system resilience and overall efficiency. Integrating feed management strategies with policy support and technological tools is critical for sustainable livestock production. Stakeholders, including farmers and decision-makers, can implement these approaches to mitigate the effects of climate variability and resource limitations. The review provides actionable guidance for improving livestock productivity in Moldova while maintaining ecological balance. The adoption of innovative feeding strategies and environmentally sustainable practices can strengthen resilience and sustainability in the livestock sector.

The main objective of this study is to establish the level of reliability of electricity distribution systems, which is currently characterized by multiple problems, because, at present, these systems have a complex configuration and are affected by a significant number of refusals, conditioned by various influencing factors. To achieve the proposed objective, the most important indicators were selected, which allow estimating the level of reliability of electricity distribution systems, regardless of structure and configuration. The main results obtained are those related to the application of the proposed reliability assessment procedure for estimating reliability indicators, which are of significant importance for the operation of electricity distribution systems, thus providing the possibility of justified planning of measures to prevent refusals and increase the level of reliability of the examined systems.; Основною метою даного дослідження є встановлення рівня надійності систем розподілу електроенергії, який на даний час характеризується множинними проблемами, оскільки в даний час ці системи мають складну конфігурацію та зазнають впливу значної кількості відмов, зумовлених різними факторами впливу. Для досягнення поставленої мети було обрано найбільш важливі показники, які дозволяють оцінити рівень надійності систем розподілу електроенергії незалежно від структури та конфігурації. Основними отриманими результатами є ті, що пов’язані із застосуванням запропонованої методики оцінки надійності для оцінювання показників надійності, які мають суттєве значення для функціонування систем розподілу електричної енергії, що забезпечує можливість обґрунтованого планування заходів щодо запобігання відмовам та підвищення рівня надійності досліджуваних систем. З метою спрощення процесу оцінки надійності, рівень надійності систем розподілу в аграрному секторі було оцінено на основі таких показників, як: середня тривалість відмов (τ); середня частота виникнення відмов (λ); середній час відновлення відмов (μ); середній сумарний час відмов (Tmed). Визначені показники відрізняються від системи до системи через декілька факторів, таких як: специфічні умови географічного розташування, кількість сільськогосподарських споживачів, що забезпечуються електроенергією, сумарна довжина ліній електропередачи в системах, конфігурації та структурні схеми систем та кількість та стан складових частин. На основі проведеного дослідження було встановлено, що в процесі оцінки надійності систем розподілу електроенергії абсолютно необхідною є класифікація та систематизація перерв у постачанні електроенергії споживачам, спричинених різними факторами впливу, в залежності від пори року та географічного розташування розподільчих систем.

One of the most important characteristics of any agricultural enterprise concerns the enormous number of decisions it faces on a daily basis. In this way, decisions are made related to the activity of the research and development department, of the marketing, production, financial, human resources, etc. Strategic decisions are taken - of long-term scope and impact, or tactical decisions - narrower in terms of time horizon and complexity. In this complex gear of decisions, those regarding marketing particularly attract attention; through its own philosophy, marketing aiming not only at the simple attraction of customers, but - and only here begins the difficulty of its conception and practice, ensuring their satisfaction after consumption. The solution of the difficult problems that the agricultural enterprise faces in the implementation of the marketing spirit in a scientific, modern way is carried out on the basis of a complex set of information, which allows it to correctly orient itself on the market and make the decisions that are optimal for it. Having valuable information, managers make marketing decisions burdened by the lowest dose of risk possible under the given conditions. Marketing research therefore provides precisely the information necessary for the organization to practice the modern marketing concept in its businesses.
