Effects of Gibberellic Acid on Winter Pasture Production

Abstract

THE problem of restricted winter growth of pastures is of agronomic importance in many countries. This is especially true over large areas of Australia where fodder conservation, as one solution, is not economic. The possibility, inherent in the work of Morgan and Mees^1,2, Leben and Barton³, Wittwer et al. ^4,5 and Corns⁶, that gibberellic acid might increase winter growth of continuously grazed pastures, does not appear to have been exploited beyond an initial experiment of Scurfield and Bull⁷. Results of that experiment were sufficiently encouraging to warrant our pursuing the matter further.
