The tomato (Solanum lycopersicum L.) is one of the most cultivated vegetable species worldwide, both in protected areas, as well as in open - field conditions, due to the preferences of consumers for this vegetable, its nutritive and nutraceutical value, also its multiple processing possibilities. At the same time, tomatoes are model plants for studies on fruit growth, development and ripening. Along with many other common factors that influence the quality of tomatoes (variety, cultural practices, timing and method of harvesting, handling, transport and storage) and taking into account the various growing conditions and possible exposure to the action of various stress factors, the primary condition for good growth and development of plants (including for promoting yield, fruit quality value, as well as technological properties) is the use of a seed characterized by a high physiological quality. In this context, the different seed priming techniques have proved effective both in favor of the germination process and increasing the vigor of the seedlings, as well as in terms of enhancing the crop productivity within the different cultivation systems. Besides these, the quality of the fruits at the time of harvest, as well as their behavior in the post-harvest period proved to be beneficially influenced by the treatments applied to the seeds. This short overview presents some noteworthy research results obtained in the last decade for tomatoes, which have proven to be of interest from the economical, environmental protection and human health viewpoint in the context of increasing sustainability.

The notion of quality is an attribute of products and services that can be evaluated in terms of good or bad. Quality represents customer satisfaction through the best product at the most reasonable price. Modern culinary production, defined by the terms cook-chill = cooked and refrigerated, cook-freeze = cooked and frozen and sous vide = cooked and vacuum-packed, has emerged as a necessity of the modern times we are going through. In this paper, we aimed to analyze the degree of customer satisfaction within the Restaurant Reforma 9 - Complex Agronomia. We completed a questionnaire, which we applied to the restaurant's customers, between January and March 2020. Due to the fact that in March 2020 started the COVID-19 pandemic, and the restaurant was closed, we managed to apply only 60 questionnaires, some of which had incomplete answers. In this study, we received help from several students from the Master of Quality Management and Management in Agrotourism and Public Catering from our Faculty. The results of the study show that, although the restaurant is a student one, where many students from our faculty work, customer satisfaction with the quality of food and services is high. Unfortunately, the COVID-19 pandemic led to the closure of the restaurant for a long time, but managers have found modern solutions to partially maintain the business.

The public participation is seen as a political principle or as a public practice, and it is also recognized as a right of the citizens, with the aim at facilitating the involvement of the segment of citizens affected or interested in a public decision. The citizen’s participation in making decisions regarding the community where he lives is an indicator of how everyone socializes, is involved in making decisions that concern him directly, regarding a new project of the local authorities. As the human resource is extremely dynamic, it is the one that highlights the other types of resources: economic, social and cultural, we elaborated a survey in four rural localities in Călăraşi county to capture the degree of citizens’ participation/involvement from the rural area in the development decisions at the level of the community in which they live. The research was achieved using on the questionnaire-based survey method and the data were processed by the analysis and comparison method, using also the χ2 test. The survey- questionnaire was used with a number of 7 items, to survey the opinion of the population, to which a number of 377 persons answered. The questions were structured on 2 levels, respectively, filter questions and grid questions. The answers in the questionnaire were analyzed according to 5 criteria, namely: by locality, by respondents’ age, by level of education, by gender and by social status. The differences in the conception of participation in the decision- making act are different between the analyzed communes, even if overall 58.27% answered that the group participation is the best. The group activities are appreciated to the detriment of the individual activities, by those aged between 30 and 60 years old, by those with high school education, farmers, employees, without status and pensioners. From the analysis of the citizens’ participation in the respective decision-making in a current way, occasionally or not at all, there is a significant and very significant differentiation at the commune level, age, studies and social status.

Price volatility is one of the main sources of risk in the production of fresh fruit, including table grapes. Sustainable functioning of the supply chain requires a detailed study of price fluctuations in the context of both - stable development of production and security and access to food for consumers. The movement and variation of producer, wholesale and retail prices of table grapes during the period 2000-2019 were studied. The changes in the relative price margins of the production prices in the wholesale and retail prices were identified. The producer prices have risen significantly in the period after Bulgaria accession to the EU until 2012. Variation in the quantity of production in the country explained 24.9% of the change in producer prices by years, as the quantity of imports, the unit price of imported products, the bargaining power of other contractors in the supply chain, changes in consumer demand also have an impact. Declining relative share of producer prices in the wholesale and the retail prices showed the weakening market positions of producers in recent years and the limited market power to negotiate a satisfactory level of purchase prices.

At the level of the European Union, Spain was the largest peach grower in 2019, with an area of 47.94 thousand ha and a production of 940.50 thousand tons, followed by Italy and Greece. Romania's peach production amounted to 17.19 thousand tons, far behind other states in the eastern part of the EU. Although it had the largest number of peach trees, 296,424, Constanța County was surpassed in terms of production by Bihor County, which obtained in 2019 5,718 tons of peaches. In order to support this sector, the Fruit-Growing Trees Subprogram of the NRDP (PNDR) 2014-2020 made available to fruit growers the non-reimbursable funds for the reconversion and establishment of new fruit plantations. For this purpose, the paper presents some aspects concerning the management of natural and anthropic resources for peach fruit trees, lands and orchards in expert system-CROM. Following the application of the expert System CROM, the peach plots and the orchards at Research and Development Station for Tree Culture -SCDP Băneasa, Bucharest received 138 points and were included into the class with natural and anthropic restrictions. Recommendations for the improvement of the peach orchards have also been established.
