millet cover crop

Catalogue: GRDC Updates
Millet can have a positive effect on following wheat yields, provided the millet crops are sown early in spring and terminated once 50 % cover is achieved... The results showed that if millet was sown early and removed early (40 days after sowing) there was a neutral or positive impact on wheat yield compared to a traditional fallow... The research shows that it is, differences in wheat yield when comparing the MF millet and CF traditional no-till fallows is significant and could be used to offset the costs of millet establishment...

Cover cropping is growing or partially growing a crop during a fallow period, the resultant ground cover will reduce the risk of erosion, aid rainfall infiltration and slow evaporation... The improved returns from the wheat compensated for the costs of establishing the cover crop... The dry weather continued after the cover crops were sprayed out and there was still a soil water deficit in May when fields were planted with wheat...

The modelled yield impacts in the subsequent wheat crop are shown below... Large scale trials were run between 2004 and 2007 with cover crops of millets or sorghum sown in the spring following a skip row summer crop and sprayed out at various growth stages... We are hoping to validate the modelling and explore fertilizer, crown rot and VAM effects...
