Gowda, who has already qualified for the London Olympics, came up with a decent effort of 64.10 meter which was though below her personal best.
The United States-based Indian had recently come up with an impressive throw of 66.28m in a meet at Norman, Oklahoma to top the world list for a brief period.
His sixth-place finish here in the prestigious IAAF event is though creditable considering that the 11-man field has some top discus throwers of the world.
Beijing Olympics silver medallist Malachowski Piotr of Poland won the event with a throw of 67.53m while reigning Asian champion Ehsan Hadadi of Iran and Zoltan Kovago of Hungary bagged the silver and bronze respectively with efforts of 66.32m and 65.77m.
It was disappointment for Luka who clocked 2:01.09 and failed to breach the sub two minute time. She could not touch the London Olympics 'A' qualification standard of 1:59.90 though she has already crossed the 'B' standard of 2:01.30.
Her today's effort was also well below her national record timing of 1:59.17 she recorded at Split in the VTB Bank Continental Cup in September 2010.
Beijing Olympics gold medallist Jelimo Pamela of Kenya won the race in 1:56.94. Magiso Manedo Fantu of Ethiopia and another Kenyan Jepkosgei Janeth bagged the silver and bronze respectively in 1:57.90 and 1:58.50 respectively.
