The Effect of Organic Fertilizers on the Spelt Yield and the Yield of its Components

The aim of this study was to determine the effect fertilization with organic fertilizers Fertil Supernova and Ilsamin N90 on yield components three spelt varieties. conducted an anthropogenized eutric cambisol at experimental site Faculty Agriculture in Zagreb during 2015/16, 2016/17, 2017/18, respectively. included varieties spelt, Nirvana, Ostro, Bc Vigor, as well a topdressing control (without topdressing). first beginning spring vegetation consisted application fertilizer amount 300 kg ha-1, while second end tillering foliar 3 l ha-1. its were significantly influenced by weather conditions, primarily distribution precipitation. studied did not differ grain yield. In all research years, variety Nirvana has achieved largest number ears per m2. Topdressing had positive impact hulled only dry year 2016/17. have significant components.
