Auginimo būdų įtaka valgomojo pūtelio (Tragopogon porrifolius L.) ir valgomosios gelteklės (Scorzonera hispanica L.) produktyvumui.

Investigations were carried out in the crop rotation experimental field at the Institute of Horticulture Lithuanian Research Centre for Agriculture and Forestry (IH-LRCAF) in 2016-2017. The aim of investigation -- to estimate the parameters of goatsbeard and black salsify productivity in the flat soil and ridge glance soil surface during different growing year. The object of investigation was the cultivar 'Mammouth Sandwich Island' of goatsbeard (Tragopogon porrifolius L.) (Germany) and two cultivars 'Hoffmann's Schwarze Pfahl' (Germany) and 'Duplex' (Netherlands) of black salsify (Scorzonera hispanica L.). Results of investigation showed that the highest total (18,1 t ha-1) and marketable (14,4 t ha-1) yield of goatsbeard and the highest total (18,9 t ha-1) and marketable (15,2 t ha-1) yield of black salsify was determined in the ridge glanced soil surface. The marketable yield of goatsbeard 4,4 % and 9 % of black salsify was higher in the ridge glance soil surface compared with flat soil. Plants distinguished with the index of root shape compared in the flat soil and ridge glance soil surface. [ABSTRACT FROM AUTHOR]
