  Potato (Solanum tuberosum) is the fifth most important cultivated crop according to its growing area and fourth by its production volume. Originated from the Andes of South America throughout the last five centuries spread over the world and became a global staple food. Over the years potato production has greatly evolved due to advancement in agrotechnology reflecting in higher yields contrary to the worldwide decreasing production area. The wide range of potato’s ability for adaptation allows it to thrive in many different soil types and climates making it a main contributor in food security. Nonetheless rising temperatures, extreme weather events, water scarcity driven by climate change imposes serious challenges and threats for global potato production.

  This review presents the short history of potato cultivation, statistics of present and past production and agroecological needs for ideal farming. The review also attempts to explore the impact of climate change on potato growing spotlighting on drought and heat sensitivity.
  To deal with these climate change induced challenges several mitigation options are proposed just as foliar applications of salicylic acid, hydrogen peroxide, silicon and micronutrients to elevate perseverance against abiotic stresses.

  I introduce the performance management from the area of human resource management that I examined at organizations operating in market environment and in the public sphere as well. The reason of my choice of subject is that the performance management got into the centre of interest also in Hungary lately.
  The scale of values connecting traditionally to the organizations of the private and public sphere is different vitally, what affected substantive differences of the organization, the management and the human resources management environment. Within these I tried to reveal their performance management system and with their comparison to draw conclusions. I did my surveys at profit oriented organizations and at organizations operating at the public sphere.
  Performance management is one centre field of modern human resource managing, as the basis of the successful functioning of any company is the possibly most effective operation of its resources. Performance management is a possibility for the company and for the employer to overview the realization of the determined aims and the factors that block or promote accomplishments. Considering the results, the employee and the manager could determine subsequent realistic and accessible aims for the following period. Achievement management is extremely
  important in those positions where achievement could not be measured accurately.
  I carried out my surveys according to performance management by observation and data acquisition. I applied questionnaire survey to collect data, or rather made deep interviews; I talked personally with more employees as well.
  The questionnaire consisted of one data format and performance management questionnaire. I processed the gathered data by computer and visualized graphically. I also did examinations by using statistic methods, by which I was able to get to know the certain organizations deeper and thus it was possible for me to reveal more connections.
