Application techniques of liquid starter fertilizer in commercial maize production

Abstract

Conventional corn production involves the use of granular fertilizer which distribution is carried out with various types of fertilizer spreaders. As opposed to the conventional production, this research is conducted with the assumption that using a combination of granular and liquid starter fertilizers, and improved application techniques, achieve higher in grain yield. In this scientific paper, in addition to the use of conventional mineral fertilizers, investigated the impact of mechanized application of different norms of liquid starter fertilizer in the production of commercial maize. The application of liquid starter fertilizer was performed simultaneously with sowing, with the existing seeder, adapted with prototype machine for the application of liquid starting fertilizer. The results show that grain yield in areas where was applied a method of application starter fertilizer, increased by 1.43 t · ha-1 compared to the results obtained with conventional production.
