Trials Calendar
UK Summer Trials Program 2025
Through the course of the season G’s Growers have trails across the farms testing new varietal innovations alongside core crop production. By trialling alongside core varieties, new products receive the same treatment as the commercial crop ensuring a fair benchmark.
The season is broadly split into three with early, mid and end of season varieties being trialled to understand crop characteristics and how varieties perform in different seasonal slots.
