CONTENT OF MICROELEMENTS IN TUBERS OF POTATO TREATED WITH BIOSTIMULATORS

摘要

Three times every 10-14 days, starting from the BBCH 39 phase, four cultivars of edible potatoes were treated with the following bio-stimulants: Asahi SL, Bio-Algeen S90 or Kelpak SL. The control object was plants potato sprayed with distilled water.The large amount of precipitation in the first year of the research contributed to an increased content of Fe and Mn in the potato tubers. The tubers of potatoes treated with Kelpak SL had the highest content of Zn, Mn, Fe and Cu. The highest content ofB was found after the potatoes were sprayed with Asahi SL. Compared to the control plants, Bio-Algeen S90 reduced the content of Zn, Mn, Fe and Cu. The content of microelements in the tubers was significantly dependent on the genotype. The highest concentration of Zn, Mn and B was found in the tubers of the cv. Volumia, the highest concentration of Fe and Cu - in the tubers of the cv. Sylvana, and the highest concentration of Ni - in the tubers of the cv. Satina. The uptake of microelements with the potato harvest depended more on the cultivar, in particular its yield, than on the biostimulators that were used.
