ABSTRACT Potato, also known as Solanum tuberosum L., is a vegetable that is grown everywhere in the world and is considered a major staple food crop. It is a member of the Solanaceae family (Ewing, 1997). The increasing population of people in the world is driving up both the demand for and consumption of potatoes every day. In order to meet the demand, modern agricultural practices, highly efficient fertilizers, and a wide range of potato cultivars are utilized (Haider et al., 2012). By providing NPK in the appropriate proportions and split dosages at different phases of crop development, it is possible to fulfill the nutritional prerequisites for plant life. When it comes to the growth and production of potatoes, NPK are the crucial elements. Sufficient phosphorus improves numerous physiological aspects of plants, including basic photosynthesis processes and roots growth, especially lateral roots development (Brady and Weil, 2008). Hence the quantitative study and analysis will therefore identify the particular dose of N:P will be selected and recommended to farmers. Cultivars that will show high yield according to results will be recommended to farmers. Insufficient or the additional use of fertilizer have a negative influence based on the quantity and quality of the tuber. This proposed experiment was performed at vegetable farm Morphou (Güzelyurt). Four varieties of potato was tested under two level of NP fertilizer and yield parameters are tested through statistics. The results of study concluded that the variety Chalanger was significantly high yielding as compared to other varieties. However, the response of fertilizer application showed maximum marketable yield of Spurta variety was obtained under (100 Kg N + 50 Kg P and 100 kg N + 75 Kg P). Marketable tubers per plant were gathered under Spurta variety Overall, the response 100 kg N + 75 Kg P significantly improve yield and quality of potatoes.
