traditional breeding as well as analytical breed-
ing with gene transfer. These breeding approaches
will necessitate an in-depth knowledge of the
potato's ecophysiology (Parry
et al
., 2005). In
addition, a better understanding of potato physi-
ology and adaptation mechanisms will be critical
for dealing with future challenges.
Simulation of potato growth and develop-
ment could provide the necessary insights into
adaptation to drought (e.g. Campbell
et al
., 1976;
Spitters and Shapendonk, 1990; Peiris
et al
., 1996;
Jones, 1998; Sinclair, 2000; Sinclair and Muchow,
2001; Passioura, 2007). However, overall suc-
cess will require collaboration across several dis-
ciplines that range from the molecular to the
ecological, with close links to climate research
(Bazzaz, 2001; Howden
et al
., 2007; Morison
et al
.,
2008; Weart, 2013).
as micro-irrigation and drip irrigation was
shown to conserve water. Soil moisture sensors
are useful monitors of soil water status and are
used to control irrigation schedules and quan-
tities. Potato production systems could probably
benefit from an LVHF soil moisture-based drip
irrigation system (Muñoz-Carpena
et al
., 2005).
The low-pressure/low-flow drip irrigation system
(Dowgert
et al
., 2006) is also a promising system
that deserves additional studies.
Current VRI irrigation regimes are based
on GPS data of uneven field conditions, topog-
raphy, microclimate, soil gradients, etc. Preci-
sion irrigation is expected to develop further and
to provide a reliable representation of the spatial
water status of crops, including in the potato
crop (Rud
et al
., 2014). This technology may fa-
cilitate VRI based on variations in water require-
ments among potato cultivars with diverse
water needs or different tolerances to drought,
and respond in real time to the crop's water
requirements at various growth stages. Combin-
ing an understanding of potato-water relations
with recent advances in irrigation management
may provide the tools necessary to conserve
water while securing potato yields under chal-
lenging climate conditions.
7.9 Summary
Irrigation management systems are constantly
improving and provide the farmer with tools
for increased efficiency of water use. Imple-
mentation of efficient irrigation systems such
