Abstract: Field investigation was carried out to study the effect of organic and biofertilizers on growth and yield parameters in potato cultivar Kufri Chipsona-3 at School of Agriculture and Environmental Sciences, Shobhit University, Gangoh Saharanpur, Uttar Pradesh condition during 2016-2017 and 2017-2018. The experiment was laid out in a randomized block design with four nutrient management practices vermicompost (VC), and their combinations with biofertilizers (PSB). Growth parameters like plant height, number of compound leaves per plant, number of shoots per plant, diameter of stem and number of stolon per plant, number of branches per plant, fresh and dry weight of shoot and yield attributing parameters like fresh and dry weight of tubers per plant, number of tuber per plant, diameter of tuber per plant and total yield per hectare increased with the application of vermicompost in different combination rates with biofertilizers was much better than applying of vermicompost one and the using of phosphate solubilizing bacteria with them in tries combinations were the most effective treatments comparing with the others. However, highest values for number of tuber per plant and per plot as well as tuber yield per plot and per hectare was recorded on application of Vermicompost @ 6 t/ha + PSB @ 10 kg/ha was the most effective treatment both the years followed by Vermicompost @ 6 t/ha, respectively.
