UHS10454 - The effect of controlled release nitrogen fertilisers on dual purpose wheat biomass production, grain yield and protein content
The application of industry standard Incitec Pivot® urea and Everris® 43% N controlled release nitrogen fertiliser on dual-purpose EGA Wedgetail 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.
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.
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.
