Yield, Quality and Nitrogen Use of Forage Maize under Different Nitrogen Application Rates in Two Boreal Locations

Research focusing on the nitrogen (N) application and N use of forage maize (Zea mays L.) in boreal region is either limited or non-existent. The aim this study was to investigate response yield, quality recovery efficiency (NRE) an increase rate different climatic conditions two locations Finland. field experiment conducted southern (Helsinki; 60° N) central (Maaninka; 63° Finland 2019 2020.
