Abstract
Approximately 45% of apricot tree plantings in South Africa are centered on Montagu, Koo and
Barrydale in the Little Karoo. Below average production in this area could be ascribed to the
deteriorating water quality of the Breede River and highly saline groundwater from boreholes
which provide this area with irrigation water. Profit margins for farmers are such that decreased
yields cannot be tolerated. Correct management of low quality water could improve production
and net farm income and could decrease irrigation return flow into the river system. The
objective of this work was to establish whether international water quality guidelines for apricot
are applicable under a different set of climatic conditions for a locally important cultivar and to
revise guidelines if necessary for the management of irrigation with saline water. A drainage
lysimeter was used to evaluate the effect of saline irrigation on apricot (Prunus armeniaca
cultivar Palsteyn) trees over a period of four years at Stellenbosch (S33° 55’; E18° 53’) in the
Western Cape.
