Purpose
To demonstrate the effect of penac-p (3041) as seed treatment versus untreated seed.Trial
Each trial was repeated four times (see H-1 to H-4) for each repetition per cultivar.Method
The penac treated seeds have been mixed with 20g penac-p (3041) per 50g seed.

The trial with the wheat showed that by dressing the seed with 20g penac-p/50kg seed a better hl mass as well as yield are achieved.
