Аннотация: Drought is a devastating abiotic stress decreasing crop productivity. This study aimed to assess the effect of seed priming with leonardite humate (LH, 0.5 g L–1) and their mixtures with polyethylene glycol (PEG6000, 200 g L–1) on radish field performance in hot, dry conditions. Hydropriming and osmopriming with PEG were also examined. A field experiment was conducted on Urbic Technosol (silt loam, pH 7.4, organic C 38 g kg−1). During the experiment, the air temperature generally exceeded the long-term average temperature; the precipitation was 68.7 mm. Priming led to an increase in the fresh mass of root crops by 23–31%, but no significant difference between priming treatments was recorded. Yield after priming with LH or PEG + LH increased by 43% and 34% as compared to the unprimed variant, which was not statistically significant despite the observed visual differences. Priming with LH or PEG + LH resulted in lower ascorbic acid content in the roots, indicating apparent partial adaptation of plants to stress. The opportunity to enhance the beneficial effect of priming by foliar treatment with biostimulants was concluded to be of interest for future research.
