Trial Data

Two researchers collecting data from a field
All varieties developed by Cropmark Seeds Ltd are thoroughly trialed and tested on farms throughout New Zealand, as well as in Australia to assess their performance capability under varying farming conditions prior to commercialization.


Only the very highest performing varieties are commercialized if they perform to the company’s stringent selection standards in line with the company’s ‘only the best philosophy’.

Forage varieties are evaluated in these trials for a number of performance- related criteria, including dry matter yield and seasonal performance, pasture quality (including metabolisable energy, digestibility, protein, NDF, etc), persistence, and susceptibility to plant diseases and insect pests.

Where necessary, the company undertakes animal performance trials to assess the impact of its varieties on livestock performance and health.

All trials are run to strict industry-designed protocols, and managed by the company’s technically skilled and experienced regional agronomists who are based throughout New Zealand, as well as in Australia.
