A survey of New Zealand's first-class cricketers, organised by the Cricket Players Association, found the University Oval had the worst wicket and practice facilities of the major grounds.
But Dykes said cricketers might be getting too picky, and pitches had to offer some assistance to bowlers.
Dykes said he was disappointed with the results of the survey, adding that comments about the pitch had not come through players' and coaches' pitch reports at the end of games.
"We acknowledge the pitch is not consistent enough for our liking," he told the Otago Daily Times.
"But we had some good pitches for one-day games and a decent pitch for the test match. But some of the four-day pitches have not been up to standard."
He said one of the four-day games was affected by a match being shifted from Oamaru, while the weather had hit another.
Dykes said the inconsistent Dunedin weather did not help pitch preparation.
Cricket Players Association chief executive Heath Mills acknowledged a huge amount of work had gone into the ground in the past two or three years, and players liked playing there.
"But the practice facilities are still not good enough. And the pitch is not as consistent as it has to be," Mills said.
He said the ground staff worked hard but were under-resourced.
"The problem is the University Oval is seen now as a premier cricket ground alongside the likes of the Basin Reserve, Hamilton and Eden Park.
"But those grounds have four or five staff just looking after the ground, where there is only one groundsman and an assistant at University Oval. They want, and have the ability, to produce quality wickets but may not have the resources," he said.
Mills said the association wanted to have the best wickets and practice facilities, as the only way to get better was to have the best of everything.
He rejected the suggestion cricketers were getting too critical and said grounds and facilities had improved greatly in the past two to three years.
The University Oval was not the worst by much, Mills said, and players accepted its short boundaries.
Dykes said the Dunedin City Council had shown commitment to developing the ground, but having just three staff and an apprentice for the Oval and the rest of Logan Park meant there was much work to do.
The association would continue to talk to the council about the ground.
That lack of ground staff had an impact on the practice facilities, he said.
"Craig Cumming said earlier in the season they were the best practice pitches he'd batted on. But as the season went on, they got worn and were not too flash," Dykes said.
He said he was not trying to make excuses, but the association was continuing to work hard and Tom Tamati was an excellent groundsman.
He said sometimes cricketers used the state of a pitch as an excuse for their own shortcomings.
"Maybe the real issue is that all around the country the standard of pitches is improving and players are getting more and more picky in their comments.
"Do we want pitches to not be able to take spin, seam or bounce?"
