Four potato varieties (i.e. Kufri Chipsona-1, Kufri Pukhraj, Kufri Lauvkar and Desiree) were investigated under water stress conditions with respect to three growth stages. The reduced photosynthetic activity of stressed plants caused a reduction in total biomass. Maximum percent reduction in total biomass production was recorded when water stress was imposed attuber initiation stage (T2) while minimum percent reduction when water stress was imposed at tuber maturation stage (T4) as compared with well irrigated control. Under water stress conditions, Kufri Pukhraj maintained total biomass higher than other cultivars. At harvest, the haulm yield was found to be reduced due to water stress at tuber initiation stage and tuber enlargement stage. Kufri Chipsona-1 recorded highest haulm yield followed by Kufri Pukhraj.
