In: Minufiya Journal of Agricultural Research 2003. v.28(1)Summary: The objective of the present investigation was to study the effect of different levels of salinity and irrigation water regime on mineral content of potato leaves. Four levels of saline irrigation water E.C.0.4, 1.5,3.0 and 4.5 dS m-1 were used in the present study. Plants in each treatments were irrigated with one of the four mentioned salinity levels either once or twice a day every two days in pots containing sandy soil during fall 1998, 1999 and summer seasons of 1999, 2000. Diamant potato cultivar was used. Twice irrigation significantly increased FW and Dw of foliage and produced a higher leaf content of chlorophyll, nitrogen, potassium and higher starch content. while it decreased the both sodium and proline content.
