Účinek kombinace hnojení dusíkem a mikroelementy na výnos a kvalitu rajčat
Koriťák, Pavel
The aim of this thesis was the evaluation of the effect of foliar fertilization by microelements combined with nitrogen fertilization on the yield and quality of tomato (Solanum lycopersicum L.) The experiment was implemented as a container experiment and field experiment. There were 5 variants of the container experiment: B1 (150 g B/ha), B2 (300 g B/ha), B3 (150 + 150 g B/ha), Zn1 (300g Zn/ha) and Zn2 (150 + 150 g Zn/ha) - all with the same dose of calcium nitrate. The field experiment was designed in Nová Červená Voda in 3 variants: B1 (150 g B/ha), B2 (300 g B/ha) a B3 (150 + 150 g B/ha) – all with the same dose of NPK fertilizer. In the container experiment, the highest NDVI was measured in Zn1 variant. The NDVI showed a significant dependence on the average yield of fruit. The lowest nitrate content was seen in Zn1 variant. The highest yield of fruit was in Zn2 variant. In the field experiment, the highest yield of fruit was in variant B3. The results of the experiments showed positive effect of nitrogen application combined with the microelements on yield and quality of tomatoes.
