Good quality potato is suitable for its use, flawless, good in nutritional value and safe to use. Good quality potato doesn’t contain pesticides, harmful substances or heavy metals. The quality variations of potato are a significant problem for potato producers as well as consumers. Problems in potato quality come up usually in the handling or production processes. The disappointments in potato quality directing consumers and institutional kitchens to substitute potato with other products can be seen as a loss of market share in the production chain. Adequate and balanced fertilization that takes into consideration the nutrient substances of the soil is an essential part of the cultivation technique of potato. Potato reacts as a demanding crop for differing or unbalanced fertilization by the yield and/or quality of the crop. In the planning of fertilization should be taken into consideration the results of soil analysis, crop rotation, line of production and varieties etc. Additionally the factors influencing the yield and quality of the crop are soil type, water management, weather conditions of growing period and storing conditions. In this research the nutrient contents of tubers varied and nutrients behaved in particular according to pH –levels. The organic matter of soils had no impact on crop yields or on nutrient contents of tubers. Cultivars differed greatly in how they responded to fertilization. Also, growing season weather conditions had a great significance to the release of nutrients from the soil. With potato quality means its external and internal properties of use and tuber’s nutritional value. In external quality a potatoes visible properties like general outlook, size, colour, mechanical damages and disease symptoms are observed. The internal quality of potato consists of chemical composition, starch content and properties of use. These properties are for example the mealiness, flavor or discolorations in raw, cooked or fried potato. In this research a connection between potato variety and cooking quality was observed. There were also other factors wich affected cooking quality; fertilizing, nutrient contents in the soil and nutrient contents of tubers. Seamless co-operation of producers and processors of potato is a necessity for securing the good quality potato for consumers. It needs to be assured that the processing of potato (cleansing, pealing, chopping and cooking up) is not to weaken the quality. In this research it was observed that there are more communication problems if the production chain of potato is long. Most common flaws in potato quality were discoloration of fresh potatoes, crusting, breaking up and scaling. Peeled and chopped potatoes in plasticpacking were used most commonly in kitchens. The use of unpeeled potatoes was raised in kitchens in the years 2011-2014. The report is presenting main results of “Better quality of potato” –project concerning potato production, processors and institutional kitchens for managing potato quality. Additionally in the report is described producers and institutional kitchens co-operation model
