The effects of nitrogen nutrition modification in Murashige and Skoog’s medium during in vitro phase on the production of microtuber was studied to find out whether it enhance their effects on the weight and size of microtuber. The results reported that the reduction in total nitrogen by nitrate concentration in media gave better response for microtuberisation. The reduced level in nitrogen helps to obtain maximum weight and size of microtuber. Varietal differences were also reported and Kufri Chipsona-1 gave highest weight of its microtuber followed by Kufri Pukhraj and Kufri Badshah in the reduced level of nitrogen treatment. However, average effect showed that Kufri Pukhraj was best followed by Kufri Chipsona-1.
