This study was aimed at identification and prevalence of potato soft rot and black leg disease agent in the potato production areas of Tokat province. In March-August 2018, 67 field surveys were carried out in Central, Turhal, Zile, Pazar, Erbaa, Niksar, Artova and Basciftlik districts of Tokat. The disease incidences were 0.25%, 0.33%, 0.31%, 0.5%, 1%, and 8% in Central, Erbaa, Niksar, Pazar, Turhal, and Zile district, respectively. In Artova and Basciftlik districts, no disease was encountered. The following tests, pectolytic activity on potato, gram reaction, catalase, oxidase, growth at 37°C and 39°C, salt tolerance, hypersensitivity reaction were applied to isolates obtained from diseased plant and tuber samples. In the PCR assay, 19 isolates were produced 434 bp product with Y1/Y2 primers specific to Pectobacterium spp., and 3 isolates were produced 420 bp product with ADE1/ADE2 primers specific to Dickeya spp. The isolates resulted positive with Y1/Y2 primers weren’t produced PCR product with ECA1/ECA2 primers specific to Pectobacterium atrosepticum. According to this, 19 isolates were identified as Pectobacterium carotovorum. With this study, the causal agent of potato blackleg and soft rot disease have been identified in the potato production areas of Tokat. Further studies will be conducted to determine the species and subspecies level of the pathogens using specific primers.

Economic literature pays a great deal of attention to economic and financial efficiency, expressed in terms of competition, concentration, productivity and profitability. This paper provides an all-embracing framework for the various existing theories in this area and illustrates these theories with practical applications. Currently, changing the size of the production potential in agricultural units in the Republic of Moldova depends to a great extent on the influence of different trends in the modification of production resources: the reduction of labor resources and agricultural land, quantitative and qualitative changes in fixed assets, and in current assets, etc. The notion of resource potential means the totality of the volume of all resources (natural, labor, material, intellectual, information, etc.) on specific enterprises, territories, branches, regions. Evaluating a broad field of research, the paper describes profit maximizing food products and demonstrates how several widely-used products can be fit into this framework. The authors also present an overview of the current major trends in the food sector and relate them to the assumptions for food products, thereby displaying their relevance and timeliness. The results include a set of recommendations for future research on this topic. The design, methodology and approach of this research is to explain why efficiency can help obtain a profit surplus, and to measure this efficiency. For quality of methodology we apply a range of statistical methods, as well as the strategic capability of organisations – made up of resources and competences. One way to approach the stategic capability of an organisation is to consider its strengths and weaknesses (for example, where it has a competitive advantage, profit, efficiency or disadvantage). Based on our research and results, we sought to understand the concepts of financial effciency and to apply these concepts to practical situations. At the start of each analysis entrepreneurship plays an important role. Most organisations have to innovate constantly to obtain profit and efficiency for food products. They need to be first into a market, or simply a follower of customers in developing new products and services. Original studies in Moldova and Poland regarding farm concentration in terms of Gini Coefficient, Gini Index and Concentration Index of the utilized agricultural area. Original calculus formula to determine the Concentration Index of the UAA for the top 10% largest farms in Moldova and UK. | agro-sector, European Union, correlation and regression, financial efficiency, food product, financial economy, productivity & profitability, resource efficiency | 20 | 103-112 | 4
