Comparison of different side-dressings on winter wheat yield

摘要

The trial with different side-dressing fertilizations for winter wheat has been conducted at Vetovo site, Croatia, in vegetation seasons 2007/08 and 2008/09. The five side-dressing fertilizations has been tested (Control - no sidedressing, KAN - 100 kg KAN ha-1 in tillering and jointing stages; M1 - 8 l of foliar NPK fertilizer 'Profert Mara' ha-1; M2 - 16 l ha-1 of foliar fertilizer, and; M3 - 24 ha-1 of foliar fertilizer) at four winter wheat cultivars (Anika, Fiesta, Gabi and Rapsodija), with previously applied 400 kg NPK 7:20:30 ha-1 for all treatments. Results showed that all foliar side-dressing treatments gave winter wheat grain yield higher than the control, and that M1 treatment showed equal in comparison with KAN side-dressing. Treatments M2 and M3 had, in comparison with the control, KAN and M1 treatments, higher yields which leads toward conclusion that foliar treatments can be recommended for side-dressing for given agroecological conditions.
