Reaction of spelt wheat cultivars (Triticum aestivum ssp. spelta) to foliar applications of fertilizers

Field experiments were carried out in 2015–2017 on medium heavy mixed rendzina. The aim of the study was to assess the yield and weed infestation of winter spelt wheat cultivars (Oberkulmer Rotkorn, Badengold and Frankenkorn) under foliar application with Santaura Pro+ or Pro Horti Micro Amin Mg fertilizers. Among the evaluated spelt cultivars, the largest yield of grain, as well as the largest number and weight of grains from ear was produced by Badengold cv., while the highest 1000-grains mass was characterized by Oberkulmer Rotkorn cv. Prohorti Micro Amin Mg foliar fertilizer was more yield-forming. Compared to the control object, three-fold application of this preparation resulted in a significant increase in the grain yield, the weight of 1000 grains, as well as number and weight of grains in the ear. Santaura Pro+ fertilizer also had a positive effect on the yielding of spelt, however differences in relation to the control object were statistically insignificant. Tested foliar fertilizers did not differentiate the weight of weed in the canopy of spelt.
