Abstract: Present investigation was carried out on influence of irrigation methods and nitrogen levels on plant growth and tuber yield of potato cultivar Kufri Bahar. The experiment was conducted at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during Rabi season of 2015-16 and 2016-17. The treatments comprising of irrigation methods (drip and furrow)and five doses of nitrogen (60, 80, 100, 120 and 140% of RDN) were laid out in split plot design with three replications. The irrigation methods showed significant differences in all the treatments in both the years. The maximum value for percent plant emergence, number of shoots per hills, plant height (cm), foliage weight (kg/m²) and total tuber yield (q/ha) were recorded with 100% of RDN and drip irrigation. Hence, 100% of RDN with drip irrigation condition have shown the best treatment combination for potato production under semiarid conditions of Hisar, Haryana.
