NFVT Hybrid ryegrass results - NZ

Graphs combine data from the National Forage Variety Trials run across New
Zealand between 1991 and 2015.


Yield is given by where the green bar ends (yield scale along bottom of graph), and
statistical variation of yield by 'H' error bars. Cultivars whose error bars overlap are
not significantly different from each other.
