The experiment entitled “Effect of planting dates and nitrogen levels on potato cv. Kufri Lima” was conducted at Research Farm of the Department of Vegetable Science, Choudhary Charan Singh Haryana Agricultural University, Hisar during winter season of 2020-21. The treatments comprising of three planting dates (25th September, 10th October and 25th October) and four levels of nitrogen (0, 75, 100 and 125% of recommended dose of nitrogen, RDN) were laid out in a randomized block design (factorial) with three replications. Results of study revealed that significantly increase in growth and yield on 10th October planting as compared to earlier and late planting. Total marketable potato tuber yield was recorded with 10th October planting with 100% RDN application (408 q/ha), closely followed by 125% RDN application (407.7 q/ha) and minimum was recorded under control. It can be concluded that 10th October with application of 100% of RDN (150 kg N/ha) provided with highest marketable yield and benefit to cost ratio (1.82). This may be due to higher marketable and total tuber yield under this treatment.
