The use of MODDUS enhances the rooting ability of HYVIDO®, enabling the hybrid barley to increase root mass and length in order to scavenge even more effectively for water and nutrients. It has the additional benefit of maintaining stem strength.
All of these factors contribute towards the three components of yield (fertile ears/m2, grains per ear, and thousand grain weight).
Seed rate impacts on all three and in ideal conditions you are looking for a an establishment of 90%, 180 plants/m2 is the target.
The first influence on fertile ears/m2 is seed rate, 200 seeds/m2 allows space for larger ears, with more grains per ear and access to more nutrients. Early nitrogen supports ear and canopy development. IZM (isopyrazam) maintains the fertile ears later into the growing season.
Grains per ear is mainly influenced by seed rate and early nitrogen determining the final number.
Thousand grain weight (TGW) is maximised through IZM extending grain fill as much as possible and MODDUS enhancing rooting and maintaining stem strength.
