Abstract: This experiment was conducted at Research Farm of the Department of Vegetable Science, CCS Haryana Agricultural University, Hisar during rabi season of 2019-20. The treatments comprising three potato varieties (KufriPukhraj, KufriGaurav, and AICRP-P-39) and four levels of nitrogen (0, 80, 160, and 240 kg/ha) were laid out in a randomized block design (factorial). The results revealed that among the various nitrogen levels, the nitrogen dose of 240 kg/ha gave superior results for various field parameters, viz., plant height at 60, 75, and 90 DAP, number of leaves per hill at harvest, leaf and stem weight per hill at harvest, the yield of tubers in different grades (up to 25, >25-50, >50-75, and >75g) per square meter and total tuber yield (q/ha), which were statistically at par with the nitrogen dose of 160 kg/ha. As far the variety is concerned, KufriPukhraj performed significantly better for all the recorded parameters. Hence, potato variety KufriPukhraj is recommended with the application of 160 kg nitrogen per hectare for cultivation in the northern plains of India.
