AbstractA field experiment is conducted at Thi-Qar Province in AL-Shatra District located about 30 Km North AL-Nassiria City to study the response of three wheat Cultivars Triticum aestivum L. to Growth regulators during 2014-2015 growing Season. The Cultivars are Latifia , AL-Rasheed and Iba 99. The growth regulators are Alga600, Atonik and Azomin32%. Factorial experiment in R.C.B.D. with three replicates is used . The results showed that Iba 99 Cultivar gives the highest plant height , Spikes/m2 and grain yield , with a means 80.83 cm , 272.25 spike/m2 and 3.06 Ton/h) Respectively . Azomin32% growth regulator gives the highest grain /spike , 1000 grain weight and grain yield , with a means 66.00 seed/spike ,43.55 gm , 272.33 spike/m2 respectively. In addition the interaction between Iba 99 Cultivar and Azomin32% growth regulator gives the highest Leaf Area , number of grain/spike and grain yield with means 45.10 cm2 , 70.00 grain/spike and 3.16 ton/ha respectively.
The combination treatment Iba 99 with Atonik growth regulator gives the highest number of spike/m2 with a mean 279.66 spike/m2 . In the other hand, the same cultivar with Atonik and Azomin32% gives the highest mean of grain yield with a amount 3.16 ton/ha.
