Field investigation during 2018-2019 and 2019-2020 were carried out to study the effect of nitrogen fertilization and iron applications on potato plants in presence or absence of azotobacter. The experiment was laid out in split-split plot design with three replications having 16 treatments arrangement as; four rates of nitrogen fertilization (0, 50, 75 and 100% N from recommended dose) as main plot, two forms of iron (soil and foliar) as sub plot and Azotobacter inoculation (presence and absence) as sub-sub plot one. The findings indicate that growth parameters (i.e. plant height, fresh and dry weights), yield attributing parameters (i.e. fresh weight of tuber (g plant -1), No. of tubers per plant, average tuber weight (g) and dry matter of tubers (%) as well as total yield; (ton fed-1), chemical content as N, P, K%, Fe mg.kg-1 in leaves and tuber, leaves chlorophyll content as well as potato quality (i.e. total carbohydrates, starch (%), vitamin C (mg 100g -1) and NO3-N;(mg kg -1) ) increased with an increase in nitrogen levels with maximum values being obtained on application of 75% N from recommended dose. However, highest values for all traits were recorded with foliar application of Fe-EDTA, also, in presence of azotopacter. So, it can be concluded that 75% N + Fe-EDTA + azotobacter produced the best potato yield and quality compared to other treatments.
