Agronomists are urging graziers to consider gibberellic acid as a boost for their pasture growth in the cold months as many move out of cropping, seeking livestock cashflow.
The data is in on the benefits of applying gib acid after trials in the Central Tablelands. It is found to be effective on boosting growth in grasses such as phalaris, cocksfoot and perennial rye, with the boost in dry matter between 300-500kg/hectare possible after application.
Agronomist Jesh Smith, Growmore, Young, said gib acid was "a cheap way to get feed". "It is a natural hormone that helps a plant grow bigger cells and therefore bigger leaves." He said the cost of gib acid was about $10/ha, and so it was the "best bang for buck" in winter as the temperatures dropped and pastures were under pressure. He recommended a three to four week holding period.
