TLDR
It is shown how the amount of water needed by the potato crop depends on climate, soil and plant characters and the effect of water stress on marketable yield and varietal differences to shortage of moisture are discussed.Abstract:
The effect of water stress on plant morphology, production rate and marketable yield is discussed based on the literature. Compared to other species the potato is a drought sensitive plant. The reduction of yield as a result of water stress can be caused by reduced leaf area and/or reduced photosynthesis per unit of leaf area. Water shortage during the tuber bulking period decreases yield to a larger extent than drought during other growth stages. The relationship between the stress parameters relative water content (RWC), leaf water potential (LWP) and stomatal diffusion resistance on the one hand and photosynthesis on the other is discussed. Further it is shown how the amount of water needed by the potato crop depends on climate, soil and plant characters. Finally the effect of water stress on marketable yield and varietal differences to shortage of moisture are discussed.read more

Different irrigation methods and water stress effects on potato yield and yield components
TL;DR: In this paper, the authors investigated the effects of two drip irrigation methods and four different water stress levels on potato yield and yield components in the early potato growing season of 2000 and 2002.

Yield and size of deficit irrigated potatoes
TL;DR: The irrigation regime that leads to moderate deficit in the beginning of the season (growth and tuber bulking periods) can achieve production results of the order of those obtained by the test treatment, well irrigated along the whole cycle, it being a clearly advisable regime.

Adaptation of potato to high temperatures and salinity-a review
TL;DR: The development of new methodology, such as association genetics in conjunction with marker-assisted selection, offers promise that stress-tolerant germ plasm can be developed as the need increases for potato germplasm that can tolerate these adverse conditions.

Evaluation of breeding strategies for drought tolerance in potato by means of crop growth simulation
TL;DR: The simulation results emphasized the complexity of selection for drought tranrance caused by the many plant processes involved, the contrast between instantaneous and cumulative reactions and the strong genotype × environment interaction for drought tolerance.
