Agronomy Insights
SY INSITOR is a tall variety – but the above ground biomass is mirrored below the soil surface. SY INSITOR has bigger roots than competitor varieties enabling better nutrient and water uptake and increased anchorage strength – all aspects that give confidence around growing SY INSITOR, especially in difficult seasons.
Its more extensive roots can enhance nutrient and water capture
Its rapid developing root system helps facilitate its yield performance.
SY INSITOR has:
- 12% extra root length
- Longer total primary root length
- Greater total lateral root length
