The effect of nitrogen nutrition with different doses and application methods on the quantity and quality of potato yield in the irrigated conditions of the Askeran region of NKR was studied throughout 2018-2019. Four fertilization variants have been studied: manure 25 t/ha+P90 – background (control), background+ N30+(35+35) - pre-sowing and split nutrition, background+N100 - single nutrition,
background+N120 - single nutrition. As a result of conducted studies and estimations of economic efficiency, it has been disclosed that among the tested variants the highest gross and commercial
yield was provided by the variant of background+ N30+(35+35), which amounted to 321.5 c/ha and 250.5 c/ha respectively. Meanwhile, 2.6 mln AMD profit has been resulted from the sale of marketable product.
