The application of the Atonik biostimulant increased the yield of two bean cultivars. The highest yield was found after a double spraying with 0.3% biostimulant. Treatments had no negative impact on the nutritional and nutraceutical quality. Atonik did not cause any significant changes in starch and protein contents. Atonik did not enhance the activity of α-amylase and trypsin inhibitors.
