“…In the experiments of Karashchuk et al (2020) the germination energy of winter wheat seeds treated with Quadrastim with succinic acid increased by 3-8% from the control, field germination was higher by 4-7%. For pre-sowing treatment of tomato seeds, soaking in fulvic acid with a concentration of 80 mg/l is recommended, where germination increased by 13%, and root lengthby 32% compared to the control (Zhang et al, 2021).…”

The first stage of modernizing cultivation of the main grain crops lies in the exogenous use of natural growth regulators and nanofertilisers for pre-sowing seed treatment. Special attention is paid to the quality of winter wheat seed material, given the high probability of seed germination in stressful climatic conditions and the need to form winter-hardy crops. Therewith, this study is relevant because modern requirements for agronomic biofortification of plant products make provision for the introduction of environmentally safe, effective, and cost-effective measures in the cultivation of agricultural crops. The use of preparations based on fulvic acids and growth regulators is an effective way to regulate the morphogenesis and productivity of winter wheat. The purpose of this paper was to investigate the effect of pre-sowing treatment of winter wheat seeds with such preparations as Fulvohumin (chelated fertiliser), 1-naphthyl-acetic acid (auxin) and succinic acid (biogenic growth stimulator, adaptogen) on germination and biometric parameters of seedlings. The study involved the use of laboratory and statistical methods. It was found that pre-sowing soaking in 1% Fulvohumin solution increased the energy of seed germination, seedlings contained a large proportion of dry matter, compared to seed treatment with 0.025% succinic acid solution or 1-naphthyl-acetic acid. In terms of germination energy and raw root mass of 7-day shoots, a combination of Fulvohumin and 1-naphthyl-acetic acid was effective. The largest total length and crude weight of 7-day seedlings were after joint seed treatment with Fulvohumin and succinic acid. According to the totality of seedling formation data, complex pre-sowing treatment of winter wheat seeds with Fulvohumin is recommended together with succinic acid and 1-naphthyl-acetic acid. Treatment exclusively with 1-naphthyl-acetic acid was ineffective. These studies are promising for programming field seed germination and mathematical modelling of winter crop growth at the initial stages of ontogenesis in the field

“…Several studies have demonstrated the positive impact of HA and FA on the growth and development of various crops, such as tomato, cucumber, maize, rice, wheat, and others (Atiyeh et al, 2002; Zhang et al, 2021; Hartwigsen & Evans, 2000; Liang et al, 2023). Our study reveals that the addition of FA can significantly promote maize growth under low nitrogen stress.…”

The potential of fulvic acid (FA) to improve plant growth has been acknowledged, but its effect on plant growth and nutrient uptake under nutrient stress remains unclear. This study investigated the effects of different FA application rates on maize growth and nitrogen utilization under low nitrogen stress. The results showed that under low nitrogen stress, FA significantly stimulated maize growth, particularly root development, biomass, and nitrogen content. The enhanced activity levels of key enzymes in nitrogen metabolism were observed, along with differential gene expression in maize, which enriched nitrogen metabolism, amino acid metabolism and plant hormone metabolism. The application of FA regulated the hormones' level, reduced abscisic acid content in leaves and Me‐JA content in roots, and increased auxin and zeatin ribose content in leaves. This study concludes that, by promoting root development, nitrogen metabolism, and hormone metabolism, an appropriate concentration of FA can enhance plant tolerance to low nitrogen conditions and improve nitrogen use efficiency.

“…However, Pirlak and Kose (2009), did not find significant differences in fruit Ph when applying rhizobacteria of the genus Pseudomonas and Bacillus in strawberry cultivation. In another study carried out by Zhang et al (2021) when applying fulvic acids in the tomato crop via foliar spray, the pH of the fruit increased by 1%. These increases in fruit pH found in this research are possibly explained by what Rodríguez et al (2004) reported, indicating that, the pH increases as the fruit reaches maturity, thus providing the characteristic flavor of the fruit, according to the species.…”

The strawberry fruit (Fragaria × ananassa Duch.) is appreciated for its aroma, color, texture and nutritional value. In conventional agriculture, the use of fertilizers damages the environment since it causes loss of soil fertility, salinity and its erosion, hence production alternatives, without harming the environment, are sought. The objective of this study was to evaluate the effect of a biostimulant based on humic substances and rhizobacteria, on the production and quality of the strawberry cultivar ‘San Andreas’. Strawberry plants cultivar ‘San Andreas’ were treated with fulvic acids + mixture of microorganisms, humic acids + Pseudomonas fluorescens, fulvic acids + Azospirillum brasilense, fulvic acids + Pseudomonas fluorescens and the mixture AH and AF + Azospirillum brasilense with two doses (d1, d2) in total 10 treatments were applied plus the control. Humic substances were applied every 15 days and rhizobacteria every 30 days. The results showed that the AFyAzoz d1 increased over control plants, the number of leaves in 38.3%, root volume in 42.6%, the fresh weight in 130% and dry weight in 63.8%, the number of fruits 50.0% and the yield in 59.5%. The AFyPF d1 favored Photosynthesis in 127.3%; AFyPF d1 increased TSS in 25%, AFyPF d2 vitamin C in 17.1% and MHyF + Azoz d1 increased in 20% the content of Phenols. Humic substances plus rhizobacteria are an ecological alternative to be used as biostimulant in the production and quality of strawberry plants.
