Využití humátů v kombinaci s bórem ve výživě řepky ozimé
 Rzymanek, Jakub
The aim of the thesis was to assess the effect of foliar application of boron (B) together with humate on yield and oil content of rapeseed (Brassica napus L.). For this purpose, a one-year field trial was evaluated. In this trial two different fertilizers containing boron were used. These fertilizers were applied both without and in combination with humate. In each treatment, a total of 300 g of B/ha (in the form of borethanolamine) and humate in a dose of 2 l/ha were applied. In one variant, humate without boron was used, in a total dose of 2 l/ha. The average of two unfertilized control treatments was used for comparison. A significant effect of boron used with humate on the yield of winter rape was reached (highest gain by 7.93%) in comparison to the control. A positive effect on seed yield was also reached by application of boron without humate in B2 treatment (+ 6.83%), which was significant compared to the control and compared to the B1 treatment too. Significant yield effect (+ 2.55%) in comparison to the control was reached also by application of humate without boron. A very small effect of boron fertilization on oil content was found. The highest oil content was reached by the separate use of humate (+ 1.19%). The treatments were also evaluated in terms of economic efficiency. Based on the results of yield obtained and economic efficiency of treatments, the B1 + NF treatment was chosen as the best one.
