Maximising yield on late drilled spring barley

Unfavourable weather in March and April has delayed the drilling of large acreages of spring barley. Despite this, with warmer weather now prevailing, yields may not be entirely compromised. Key to this will be maximising the number of ears/ m2 and grain size.
Physiological studies have found that in the absence of disease SiltraXpro increases tiller survival and leaf chlorophyll content
The three components of yield are:
- Number of ears per unit area - number of shoots that survive
- Grain numbers per ear - spikelet production and survival
- Average grain weight - grain development and filling (dependent on leaf area and chlorophyll)
“Survival of tillers and spikelets is favoured by good light interception, photosynthesis and growth during stem extension. Potential grain size and dry matter storage capacity are determined by ovary development during booting, as well as endosperm development in the two or three weeks after ear emergence”
