| Abstract:
In the field experiment, with apple Jonagold variety, the effect of different ways of selenium application on replant soil was examined. The investigated orchard was planted on a brown forest soil with very low Se content (133 μg/kg). The selenium was applied as Na2SeO4. The experimental treatments were as follows: 0 kg Se/ha, 0.5 kg Se/ha, 1.5 kg Se/ha, 0.1% foliar spraying and by special root-soaking application. In each experiment five separated trees were treated and analyzed as one replication. Unfertilized apple trees gave the lowest Se concentration in leaves (0.03 μg/g) and fruits (0.04 μg/g), while the highest dose of Se its increased significantly up to 3.22 μg/g and 2.81 μg/g respectively. The Se foliar application was less effective, especially on the Se content in fruit (0.20 μg/g), and this is not in accordance with the Se increase in leaves (1.78 μg/g). | |
