Field-scale Demonstration of Prevention of HVAC Dockage in Kronos Durum by Late Season Nitrogen Application

Grain quality is important to growers and buyers of durum. Growers are usually docked if their HVAC drops below 90% or their grain protein is below 13 %. The purpose of this study was to demonstrate the ability of nitrogen fertilizer application near flowering to increase HVAC and grain protein. Six...

Description
Summary:Grain quality is important to growers and buyers of durum. Growers are usually docked if their HVAC drops below 90% or their grain protein is below 13 %. The purpose of this study was to demonstrate the ability of nitrogen fertilizer application near flowering to increase HVAC and grain protein. Six commercial sites were chosen for this study and Kronos was the variety. The application of about 50 pounds of nitrogen per acre increased HVAC by from 81 to 93% and increased grain protein from 11.2 to 12.3% on average, similar to results obtained in the past.
