Summary
This study aimed to evaluate the effect of different application rates of controlled released nitrogen fertilisers on crop biomass production, plant nitrogen content and grain yield in a high rainfall climate
Conclusions

The application of industry standard Incitec Pivot® urea and Everris® 43% N controlled release nitrogen fertiliser on dual-purpose EGA WedgetailPlant Breeders Rights wheat increased early production of biomass and plant nitrogen content compared with uncoated urea. Everris® 43 %N polymer coated urea showed the greatest dry biomass production compared with the unfertilised control and other fertilisers. Both Incitec Pivot® urea and Everris® 43% N showed strong early biomass production during the both grazing events although Everris® 43% N gave the highest protein percentage and grain yield at harvest compared with the other fertilisers. This data supported the hypothesis that controlled released nitrogen fertiliser can potentially increase dry wheat biomass production, grain protein and yield with higher application rates of Everris® 43% N performing better compared with industry standard Incitec Pivot® urea.

Recommendations

Controlled released nitrogen fertilisers Everris® 43% N on dual-purpose EGA WedgetailA wheat increased early production of biomass and plant nitrogen content during the grazing events. Following the grazing events Everris® 43% N showed the greatest yield responses for both grain yield and protein compared to the other products.

Achievements/Benefits

Overview of Project Achievements

This project indicated that the data supported the hypothesis that controlled released nitrogen fertilisers can potentially increase dry matter, grain portein and grain yield.
