GRDC Southern NSW Trials – Impact of N Placement and Timing on Crop Yield and Ryegrass Population (2nd Year)

Funded by Ag Grow Agronomy and GRDC.

This trial aims to get a better understanding of the benefits, in terms of increased yield, increased crop competition and reduced ryegrass seed set when using Nitrogen application under the seed row versus top dressing or spreading then Incorporating by Sowing (IBS).

2018 will be the second year of the trials, allowing a better understanding of the effect of N placement on weed numbers, over multiple growing seasons. This will allow us to fine tune best management practices that not only lead to higher N utilisation and crop yield, but also lower weed seed set following harvest.
