Trial location(s) Port Broughton, SA
Seed rate x UAN application x soil type response in wheat locations
Aims
In a grain grower planted paddock with 3 different seed rates, differing rates of UAN are applied to observe the effect on grain yield and protein. Trial is conducted in both sand dune and loam swale in order to establish best management strategy
Key messages
There are numerour interactions between soil type, mineralisation level, PAWC and tiller response inthis trial. Generally speaking the trial showed that applying more nitrogen resulted in increased protein but not necessarily yield
