Row spacing by nitrogen demonstration in barley locations
Aims
  • To assess the potential yield losses when increasing the seed row width for the benefits of subsequent inter-row (no-till) cropping;
  • To determine if nitrogen application efficiency can be increased in wider row spacing by applying product in a linear manner.
Key messages

Results from this demonstration suggested that in the dry season of 2006, there were yield benefits from wider row cropping. Whilst the results showed no significant differences between the nil nitrogen by row spacing treatments for yield (see Table 1. shaded plots), correct placement of nitrogen during the season for wider row spacings showed a yield advantage.
