National Priority: FCR-Production of high-quality export-grade fodder
This research proposal looks to assess the change in percentage of head emergence of oaten hay crops when plant hormones are applied. Poor head emergence of current oaten cultivars is proving to be a significant challenge to growers in marginal cropping regions. Incomplete head emergence increases both dry down time and hay combustion fire risk while reducing overall hay quality. Overcoming poor head emergence will offer hay producers in marginal growing areas significant efficiency and economic benefits.
The project will use replicated small plot field trials to assess the hormone type x hormone rate x hormone application interactions on quality parameters. The trial will be conducted at a single location for a single season to gather preliminary data for further experimentation. The Kimba and Mid North (SA) regions have been chosen for the trial due to the low yield potential and knowledge growers have significant issues most seasons with head emergence. Agronomic and economic analysis will be conducted to determine what potential benefits hormone applications offer to hay producers. Project results and outcomes will be extended through Farming Systems Groups, Hay Exporter Customer and AgXtra Databases.
Increase percentage head emergence of oaten hay crops grown in low rainfall areas using plant hormones.
- Assess the effects applying plant hormones (auxin, cytokini and gibberellic acid) on head emergence and hay quality
- Assess the effects of application timing of plant hormones (auxin, cytokini and gibberellic acid) on head emergence and hay quality
- Assess the effects of application rate of plant hormones (auxin, cytokini and gibberellic acid) on head emergence and hay quality
- Provide economic analysis on the effects of change in quality parameters on gross margin
