“…The degree of their effect in vegetable roots depends on the dose and the frequency of application, among other factors [10,11]. According to a previous study [12][13][14], the single application of Kelpak seaweed biostimulant was favorable for carrot root yield and quality (increased total sugars, reducing sugars, vitamin C and nitrates).…”

The application of biostimulants to prevent stress-related losses and increase productivity is becoming an increasingly common practice. A study was carried out to determine the effect of the type and methods of biostimulant application and long-term storage on the content of antioxidant compounds determining the processes of the enzymatic browning of carrot roots. The natural seaweed biostimulant Kelpak and synthetic Asahi were applied as part of the study. A quality assessment of carrot roots was carried out directly after harvest and after six months of storage in air at a temperature of 1 °C and a relative humidity of 95%. A single application of Kelpak seaweed extract in the four-leaf phase (2 or 3 dm3 ha−1) proved to be the most effective for reducing oxidative darkening processes (by 33.5%). The oxidative potential was most strongly dependent on the anthocyanin (r = −0.477) and chlorogenic acid (r = −0.474) contents. The concentration of polyphenols (r = 0.836; r = 0.719) and flavonoids (r = 0.671; r = 0.729) had the greatest effect on the antioxidant capacity (FRAP and ABTS respectively). It was observed that pectin, polyphenol, chlorogenic acid, flavonoid and anthocyanin concentrations tended to increase after a single application of Kelpak in a dose of 2 dm3 ha−1. A long-term storage period had a stronger effect on the increase in the oxidation potential than on the antioxidant capacity FRAP value.

“…Nonmicrobial biostimulants of different nature have been reported to reduce nitrate levels in carrot roots [ 64 , 70 ]. On the other hand, there are studies that the biostimulant application did not affect the nitrate content in carrot roots [ 25 ]. In our study regardless of the biostimulant used, organic carrots contain about 2-fold lower content of nitrate than nonorganic ones, and probiotic preparations did not show a significant effect on nitrate accumulation ( Figure 6 ).…”

“…According to [ 23 ], the highest levels of vitamin C content in tomato fruits were obtained after the inoculation of two bacterial strains B. amyloliquefaciens (FZB2 and FZB42) in different treatments. We also found data that the use of biofertilizers in the cultivation of carrots led to an increase in the produced biomass, and modified the chemical composition of roots [ 2 , 24 , 25 ]. Nevertheless, there is still a lack of knowledge about the effects of probiotics on carrot productivity and yield quality.…”

The interest in studies focused on applying probiotic microorganisms is increasing due to sustainable agriculture development. In this research, we aimed to evaluate the impact of two commercial plant probiotics—ProbioHumus and NaturGel on carrot growth, yield, and quality in organic and nonorganic production systems. The research was carried out under laboratory and field conditions. Plants were treated with probiotics (2 L/ha) at the nine leaves stage. Biometrical measurements and chemical analyses were performed at a maturation stage. The average weight of carrot roots increased by 17 and 20 g in the test variant with ProbioHumus as compared to the control in the organic and nonorganic farms, respectively. Plant microbial biostimulants ProbioHumus and NaturGel had a positive effect on the quality of carrots from organic and nonorganic farms: applied in couple they promoted the accumulation of monosaccharides, ascorbic acid, carotenoids, phenols, and increased antioxidant activity. Quantitative nitrate analysis regardless of the biostimulant used revealed about twofold lower nitrate content of carrots from organic than nonorganic farms, and probiotics did not show a significant effect on nitrate accumulation. Finally, ProbioHumus and NaturGel were effective at low doses. The use of microbial biostimulants can be recommended as an element of cultivation for creating ecologically friendly technologies.

“…Biostimulants have shown potential in many agricultural crops, but the efficacy and specificity of probiotic products in improving cereal yields and soil structure are not well studied. There are few studies on the effects of PPM on vegetable and fruit yields, and particularly on the accumulation of bioactive compounds [ 19 , 20 , 21 ]. Knowledge of the effect of probiotics on growth, crop productivity and yield quality in wheat ( Triticum aestivum L.) and oats ( Avena sativa L.) is very limited.…”

The aim of this study was to determine the influence of microbial biostimulants on wheat and oat growth, grain yield, and grain quality and to evaluate the influence of these probiotics on some soil agrochemical traits in the open field. Active concentrations of ProbioHumus and NaturGel and their mixtures were selected under laboratory conditions using winter wheat as a reference plant. Probiotics had a biostimulating effect on the development of the underground and aboveground part of winter wheat when 2 µL/g was used for seed priming and 2 mL/100 mL for seedling spraying. Under field conditions, after treatment of soil (2 L/ha), wheat and oat seeds (2 L/t), and plants (2 L/ha) with ProbioHumus and NaturGel, it was found that the yield of the studied cereals increased, on average, by 0.50 t/ha to 1.09 t/ha. ProbioHumus promoted protein accumulation in the investigated cereal grains. The level of microelements in wheat and oat grains increased after treatment of plants with NaturGel. Probiotics improved soil agrochemical properties, such as total and nitrate nitrogen, total and available phosphorus, organic carbon, humic acid, and humus content. In conclusion, plant probiotics can be used as an ecological alternative for growing cereals and improving the agrochemical properties of the soil.
