Early sown (March) wheat - effect of plant density locations
Aims

The objective of this trial was to compare a commercial plant density for dual purpose and grain-only production with reduced rates
comparable to that used for early sowing in the UK.

Key messages

The effects of plant density (50, 125, 200 plants/m2) on growth and grain yield of early sown wheat were evaluated. Early in the growing season the low density plots looked very sparse but by September had largely caught up whereas the highest density plots looked visually good during early tillering but later in the season tillers were visually thinner and prone to lodging.
