A field experiment was conducted to observe nitrogen efficacy for split application to potato crop. Urea (N 46%) was applied @ 250 kg per hectare in split doses to potato cultivar named PARS-70. Data regarding various growth and yield characteristics like germination, number of stems/ plant, plant height, number of compound leaves per plant, number of tuber per plant, mortality percentage, weight of tubers per plant (g), and per plot (kg), tuber yield per acre (tons) and per hectare (Tons), total Biomass per plant (g), foliage fresh weight per plant (g), foliage dry weight per plant (g), tuber dry weight per plant (g) were recorded and analyzed statistically following standard procedure at 5% probability level. T6 which received the total amount of Nitrogen in 5 splited applications produced best results regarding all the studying parameters while T1, received only basil dose of Nitrogen, produced minimum of all the above parameters.
