I graduated with First Class Honours in Agriculture from Massey University in 2009. My thesis involved investigating the effect of Gibberellic acid and nitrogen on pasture dry matter yield using the commercially available product ProGibb® SG (a.i 40 Gibberellic acid). This research concluded that Gibberellic acid is another useful tool available to farmers to help them achieve the balance between feed supply and demand. My parents farm at Waihi and have been using Gibb-Gro (a.i. 90 Gibberellic acid) since last spring after previously using ProGibb® SG. I am seeing no major variation in the dry matter responses achieved with Gibb-Gro compared to those achieved with ProGibb® SG. The one difference that is noticeable between these two commercially available Gibberellic add based products however is the cost per hectare with Gibb-Gro being noticeably cheaper. We continue to use Gibb-Gro.
