“…A lot of studies which have been conducted so far showed a positive influence of a pre-sowing treatment of seeds with physical stimulants (laser light, magnetic and electric fields, gamma radiation, etc.) on the stimulation of germination, initial development and yielding of selected cereals [11][12][13][14][15][16]. Reports available in literature also mention increased content of photosynthetic pigments [17][18][19][20][21] and increased protein concentration [17,20] in crops and vegetables grown from seeds subjected to electromagnetic stimulation prior to sowing.…”

The study aimed to determine the impact of laser light (L), magnetic stimulation (p) and silver nanocolloid (AgNC) on pumpkin seeds on the germination rate and content of photosynthetic pigments as well as the efficiency of photosynthesis and greenness index in the plant’s development stages. Seeds germinated after the use of various combinations of different refining techniques. The best results were observed for the alternating magnetic field, where the germination energy increased significantly by 20% relative to the control. A similar effect was observed in terms of germination capacity which increased by 4%. A decrease in terms of emergence rate was observed in all study groups. Leaves grown from seeds soaked in nanocolloidal silver on platters were characterised by a significantly higher content of chlorophyll a and b by, respectively, 53 and 11%, as well as 79% higher carotenoid content. The leaves of potted plants contained 42 and 43% more chlorophyll a in groups p and AgNC. In addition, 66 and 81% more carotenoids in groups L and p. At the stage of the onset of flowering of pumpkin, an improvement in terms of photosynthetic efficiency and greenness index was observed in all study groups. The highest improvement was recorded for seeds soaked in silver and reached 23% (intensity of photosynthesis) and 11% (greenness index SPAD).

“…This phenomenon may result from the activity of microorganisms contained in the preparation, which accelerated the decomposition of organic compounds and the release of nutrients from the soil. On the other hand, Szymanek et al [82] reported a negative impact of EM on the amount of available forms of soil phosphorus, potassium, and magnesium. Likewise, long-term studies by Pranagal et al [71] did not confirm the positive effect of EM on the physical properties of the soil, and the application of the preparation led to a decrease in the content of organic carbon in the soil.…”

In order to meet the global nutritional needs of a growing population, attempts are being made to develop strategies that can effectively offset the negative effects of intensive farming. The aim of this study was to investigate the effect of Effective Microorganisms (EM) preparation and organic matter incorporation on the soil microbiological and chemical features. The analyses included the number of heterotrophic bacteria, fungi, actinobacteria, cellulolytic, amylolytic and proteolytic microorganisms, and bacteria of the genus Azotobacter. The content of organic carbon, the total and mineral nitrogen forms of phosphorus, potassium, magnesium, and the pH were also determined. The application of an EM of higher dose combined with the manure and straw resulted in the highest abundance of heterotrophic bacteria (165.1 × 106 cfu g−1), actinobacteria (43.2 × 105 cfu g−1), cellulolytic (17.2 × 106 cfu g−1), and proteolytic bacteria (82.0 × 106 cfu g−1). The highest content of chemical parameters was always observed in the experimental variant, including biomass incorporation, accompanied by EM use. The novelty of our research is the analysis of the synergistic effect of the experimental factors studied on the microbiological and chemical parameters of arable soils.

“…Moreover, in a study on He-Ne light stimulation, the processing intensified the response to drought in wheat seedlings [Qiu et al 2017]. Influence of red light (RL) and the use of effective microorganisms (EM) was observed in a study on the growth, grain and straw yield in two wheat cultivars [Szymanek et al 2020]. Michtchenko and Hernández [2010] observed an increase in the number of wheat seeds germinating correctly and decrease in those germinating incorrectly under the influence of stimulation with laser light at the wavelength of 980 nm with exposure time of 30 and 60 s.…”

The study pertained to environmentally-friendly methods in the cultivation of cereal, and aimed to manage the quality of rye and triticale seeds and determine the impact of seed conditioning using effective microorganisms (EM), red light (RL), and a combination of the two (RL × EM) on the yield of grain and straw. Moreover, the seeds were sown into soil with and without EM conditioning, designated as 0 and PEM. The yield fluctuations depended mostly on the studied rye and triticale cultivars. The best effects we observed in soil without EM conditioning for Dańkowskie Złote rye and Moderato triticale. The increase in grain and straw yields was, respectively: 26% (RL), 31% (RL × EM), 40% (EM), and 17% (RL × EM), 23% (RL), 32% (EM) – Dańkowskie Złote, 27% (RL × EM), 44% (EM), 46% (RL), and 17% (RL × EM), 51% (EM), 78% (RL) – Moderato. In turn, seeds exposed to the experimental treatment and sown into soil containing EM produced reduced yields in both of the above cultivars. It is noteworthy that the conditioning methods employed in the field experiment can facilitate increased yields but most importantly contribute to the resilience of agrosystems and can therefore have environmental benefits.
