Abstract
This study was conducted in AL- Shatra , Thi-Qar province during 2010 growth season, to study the effect of potassium fertilization with level ( zero , 1 , 2 , 3 kg / Trees / year ) on some physical properties (fruit weight, seed weight and flesh weight) and some chemical properties (moisture content, TSS, reducing and non reducing and total sugars )and yield o f date palm c.v. Sayer . C.R.B.D. with three replicates was the design the results showed that: The fertilization with 3 kg / Tree / year potassium fertilization gave asignificant superiority in all physical properties of ( Rutab stage ) include , fruit weigh , seed weight and flesh weight increament ratios were (20.00 , 19. 67 , 20.00 % ) respectively as compared with control treatment and same trend in all chemical properties (moisture content, TSS, reducing and non reducing and total sugars) increament percentage were (16.39 , 12.28 , 17.19 , 30.69 , 18.18 %) compared with control treatment and also fertilization treatment with ( 3 kg / tree / year ) resulted in significant increase of yield presented in bunch weight it which (67.19 %) compare with control treatment.
