The main aim of this work was to evaluate the effect of flat (UNI) and variable application (VRA) of mineral nitrogen fertilizers (NF) on the yield of winter wheat grain using yield maps. VRA NF technologies represent a wide range of procedures and processes that are a part of precision farming. The technologies are used to optimize the applied NF dose in order to fertilize high-yield crops with regard to their nutritional needs and the condition of the land where they are located. VRA NF on winter wheat fields we...

Variable rate application (VRA) of fertilizers represents specific crop management where N is applied on the basis of information about field yield potential, plant health and quality. The main goal of this study was to assess the influence of nitrogen VRA (VRA-N) on grain yield and nitrogen use efficiency in winter wheat production. The VRA has been realized according application maps only for production and qualitative dose of N. Application maps for individual fields were prepared by SatAgro Company on the basi...

Variable rate application (VRA) of mineral nitrogen fertilizers (NF) represents one of the parts of the new farming practice пїЅ precision agriculture. VRA has been developed to address the spatial variability of fields and vegetation. The objective of this study was to assess the potential effect of VRA of NF on qualitative parameters of grain and grain yield in real farm conditions. Assessment of the potential effect of VAR of NF application was performed in Spearhead Czech Company which has been using VAR techn...
