Issue Date: | 17-Nov-2019 | Journal: | Acta Agriculturae Scandinavica Section B: Soil and Plant Science | Abstract: | © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group. Biofortification experiments with three winter wheat cultivars treated with sodium selenate through foliar- and soil-fertilisation were conducted at two locations in Croatia and Serbia in two consecutive years to increase the selenium (Se) concentration in bread-making wheat grain. The treatments were: (a) 5 g ha−1 Se foliar-, (b) 10 g ha−1 Se foliar- and (c) 10 g ha−1 Se in soil surface-application and they were compared with (d) control. Both Se foliar- and soil-fertilisation increased the Se concentration in grains from 2.6- to 4.6-fold. The concentration in grain was highest with Se foliar-fertilisation of 10 g ha−1 and it was increased by 29–32 µg Se kg−1 dry weight for each gram of Se applied per ha. The wheat cultivars differed in grain yield and Se uptake (g ha−1 Se). However, on average, there were no differences between wheat cultivars with respect to Se grain concentrations. Agronomic use efficiency (by grain) was significantly higher for Se foliar- (19%) than for soil-fertilisation (13%). It can be concluded that agronomic biofortification of winter wheat can be effective in increasing Se grain concentration, where the efficiency depends on the rate of Se applied, application method and local environmental conditions rather than on cultivar differences. | URI: | https://open.uns.ac.rs/handle/123456789/43 | ISSN: | 09064710 | DOI: | 10.1080/09064710.2019.1645204 |
