A field experiment conducted at the Experimental Station in Czesławice was aimed at assessing the effect of biological preparations in various combinations on the yield, weed infestation, and grain quality of spring spelt wheat cv. ‘Wirtas’. Single and double spraying treatments with Herbagreen Basic, Bio-algeen S90, and Asahi SL were included, and a control object and an object with full chemical protection. The experiment showed no significant effect of biostimulants on yielding, weed infestation parameters, and potassium and calcium content in spelt wheat grain. In contrast, magnesium and sodium content was significantly higher compared to the objects without the use of biological preparations. The use of chemical field protection resulted in a significant reduction in the number and dry weight of weeds relating to the control object but did not affect the grain yield. Herbagreen Basic, Bio-algeen S90, and Asahi SL can be recommended for spelt wheat cultivation and spelt wheat plants' productivity on objects where biopreparations were used, and full-field protection was similar.
