Daly and Harvey run Te Onepu and Longridge, two properties both within 30 minutes' drive of Hastings.
The field day will be at Te Onepu, 2849 Raukawa Rd, and because of its location and comparatively close proximity to Hastings is expected to attract more than 250 people.
Awards committee chairman and former Farmer of the Year Peter Tod said although Davy and Harvey's focus is "100 per cent" on friesian bulls, Daly has "a real story to tell" around friesians and feeding.
"He is very focused on growing good quality grass and doing it sustainably," Todd said.
"Anybody can look at that information, take it back to their farm property and look at implementing it, whether they're running bulls, cattle, sheep or whatever.
"I'm not a friesian bull farmer, but I am excited to learn from what he is doing.
"You could make a very good career out of looking at and learning from these field days."
The Primary Sector Awards, attended by more than 400 people, comprised eight presentations for achievements throughout the agricultural, horticultural and farm forestry sector of the region, built around the Hawke's Bay Farmer of the Year Award, which was first presented in 1972.
Among the winners were Pan Pac Farm Foresters of the Year Graeme and Neil Fontaine who will stage a field day on May 9, and Horticentre Trust Hawke's Bay Horticulturists of the Year Leon and Robyn Stallard, who will hold a field day on a date to be confirmed.
