How do they compare?
We have compiled the results below to show starch yield (t/ha) and starch content (%)
– these are the key targets we look for in ‘ultra early’ hybrids.
A high starch yield makes maize economic to grow in marginal areas, when
combined with the protein and sugar from grass silage.

32 Maize PortfolioDrilling Tips
Optimum drill timing depends on soil conditions, temperature and seedbed moisture.
Modern hybrids have a high degree of cold tolerance but should not be drilled before
soils have reached an even temperature for 3-4 days (8°C for light soils, 10°C for heavy
soils) to give the best possible establishment.
Considerations before drilling
n Soil temperature
n Seed bed and soil structure
n Moisture availability
n Short term weather forecast
Drilling considerations
n Soil type (heavy, medium or light soils)
n Seed rate
n Site and yield potential (e.g. warm site with light
soils, cold site with heavy soils)
Effects of premature drilling
n Slowed germination
n Uneven emergence
n Reduced nutrient uptake
Effects of late drilling
n Delayed harvesting
n Requirement for earlier maturing varieties
n Increased risk of lodging
