Intenzita mimokořenového příjmu bóru rostlinou řepky ozimé
Zhoř, Jiří
The aim of this thesis was the evaluation of the foliar application of selected foliar fertilizers in the plant nutrition of winter oilseed rape plant (Brassica napus var. napus). In the container experiment, there was observed the efficiency of different doses of foliar applied fertilizers containing boron in various forms, such as boron ethanolamine (Borosan Forte) and boron bonded to a chelate (Lifio Boron). The container experiment was implemented in the greenhouses of the Department of Agrochemistry, Soil Science, Microbiology and Plant Nutrition at the Faculty of AgriSciences at Mendel University in Brno. The evaluation of the effect of fertilizers was based on the weight of winter oilseed rape plants and on the amount of absorbed B after 2, 6 and 10 days after foliar application. The highest absorbed amount of boron in the plants was observed in the variant C (dose 300g B/ha) and the lowest amount in the variant B (dose 150 g B/ha). The results also showed the positive effect of boron foliar application on plant growth and dry mass production.
