Abstract
The aim of this work was to study the effect of soil moisture, quality of irritation water, auX soil texture on potato growth anj yiolj. Beáides, the stujy incluJenl the chanjes of soil structure Jue to growth of potato plants. In the quality of irriatiun water oxpcrimnt, the changes of physical ant some chemical properties ware also stujiuJ.
The exjeriment was oarrlea out in fil plots anu pot trials. The filJ soil was claycy in texture at the three seasons. Tiw same tcxtur& was usJ in the quality of irrigation water experiiunt. The soils ustil in the put expLri— ments were of sanJy loam, sanay clay loam, and clay texture,
The soil moisture l.jvls taat were useti in both fielj anJ pot excrimtnts were 40,60, ant: 60% of the field capacity. The water salinity Ljvtls, were Q.32, 2.2, and 4.0 mmhos/cm at 60 F.C. soil moisture.
The tested potato cultivars were Alpha, Claudia, anJ King EJwarJ. The growth data was taken luring the giowing perioti. Data the yield soil paramttrs were taken at the end of each season. Fiela soil wnples were takem t0 the depth of 30 cm every lo cn aZ2L to the depth of 21 CJ;t evbry 7 cm in th pats.
