Purpose: The aim of this study was to assess the changes that occurred in grape production and the wine market in Poland in the years 2009-2021. In addition, an attempt was made to assess the impact of thermal conditions on the development of grape cultivation in Poland. Design/methodology/approach: Changes in the number of vineyards, grape cultivation areas, grape harvests and the production and sale of wine in Poland were analysed in detail. The analysis was conducted based on data from the National Support Centre for Agriculture (KOWR) and the Institute of Meteorology and Water Management (IMiGW). Findings: The research indicated that grape cultivation and wine production developed dynamically throughout the period in question. It is worth noting that most of the observed changes took place in the form of an exponential trend, which also points out the level of interest shown among producers and consumers in this industry and its potential. The study also showed that the distribution of vineyards registered at KOWR relative to the thermal conditions in a given region is relatively proportional across voivodeships (provinces). The voivodeships in which, based on the average sum of active temperatures from 2009-2021, relatively conducive conditions for the development of grape cultivation existed were also indicated. Research limitations/implications: The research period covered only 11 years, this type of research requires further analysis to determine in the long-term further possibilities for the development of wine production in Poland.

Purpose: The aim of the study was to rate the employee’s productivity on different work day organization and to indicate the most optimal work schedule. Design/methodology/approach: For the research presented in this paper, strong literature review was done. We showed why human workforce is so important in tissue culture laboratory and why proper work organization is essential for increasing competitiveness of companies. Literature in the field of overtime work and short, elastic hours of work was also presented. Our research design checked effectiveness of work of ten employees of tissue culture laboratory in five different workday schedules. First combination was control and four other investigated influence of six hour work on main task in different arrangements on productivity. Data was statistically analysed with Kruskal-Wallis ANOVA. Productivity Index and Labour Productivity Index were also used for better results processing. Findings: The highest employees productivity is concentrated in the middle of work day. In conventional eight hour workday, the highest productivity is just after fifteen minute break. Six hour workday has big potential in increasing work, especially when main task is not interrupted by other activities and when work starts at the beginning of workday. Research limitations/implications: In future, research should be expanded on employees efficiency in work with bioreactor and costs analysis of plant production in such system. Practical implications: Our results are directed to plant tissue culture companies and others where employees are essential and their work requires concentration during repetitive activities. We suggest solutions increasing work efficiency. Originality/value: Our work presents hour after hour analysis of work efficiency in different workday organization in plant tissue culture company.
