An experiment was conducted at Breeder Seed Production Centre (BSPC), Debiganj, Panchagarh under AEZ-3 (Tista MeanderFloodplain Soil) during the Rabi season of 2013- 14 and 2014-15 to study the effect of foliar application of zinc on the yield and quality of potato. The treatments comprised foliar application with six different concentration of zinc such as: T1 (0 ppm Zn), T2 (140 ppm Zn), T3 (280 ppm Zn), T4 (420 ppm Zn), T5 (560 ppm Zn) and T6 (700 ppm Zn). The experiment was laid out in a randomized complete block design (RCBD) with three replications. The tuber yield of potato was significantly influenced by the foliar application of different concentration of zinc. The maximum yield (37.2 and 36.7 t ha-1 for 2013-14 and 2014-15, respectively) was found in 560 ppm Zn application. The highest dry matter content of potato tuber was found in this treatment. The highest gross margin and marginal benefit cost ratio were recorded in the same treatment. T5 (560 ppm Zn) also showed the minimum weight and rottage loss of potato tuber. Therefore, foliar application of 560 ppm Zn can be recommended for quality potato production.
