الملخص EN

A study was conducted during the growing season of 2013- 2014 at Alhartha district , Basrah province at commercial orchard that.

Effected by salinity to evaluate the effect of the addition of sulfur ,calcium and citric acid to improve salt tolerant and fruit quality and quantity of date palm cv.

Sayer at rutab stage .

sulfur were used at tow levels(100 and 200 gm\ tree) and tow levels of calcium as calcium nitrate (50 and 100 gm\tree) and tow levels of citric acid (50 and 100gm\tree) .

the addition of those materials were done at two different time , the first addition was at the middle of October and the second one at the biggining of March .

Results showed addition Sulfur (200gm\tree) improved physical and chemical characteristics ( fruit length , diameter , size , mesocarp , weight, seed drymatter , moisture content , redusing sager , total suger and sucrose ), wheras the addition of sulfur (100 and 200 gm\tree) increased total soluble solids and reduced total titrable acidity .

Results also showed that the addition of citric acid (100gm\tree) increased fruit length , reducing suger and total suger and reduced sucrose .

total soluble solids was increased by addition of citric acid at both levels (50 and 100 gm\tree) .

Results also showed that the addition of sulfur (100 and 200 gm\tree) , calcium (50 gm\tree), and citric acid (100gm\tree) caused an increased of bunch and total yield compaired with control treatment .
