Pre-sowing laser light stimulation is a method commonly used to increase the productivity of legume species. However, it has not been proved that single-laser light stimulation is a more effective technique for enhancing plant productivity and seed yield quality than using different laser lights in sequence, by which means synergistic relations are produced. A two-year, single-factor field experiment was performed in order to test selected combinations of light stimulation of soybean seeds, the effectiveness of which would be expressed as increased plant yield and improved quality parameters. Pre-sowing light stimulation of soybean seeds was shown to significantly influence the morphological traits of the plants. It significantly increased pod number, pod weight, seed number, and seed weight compared to the control. Coherent laser light stimulation of soybean seeds with a helium–neon laser and with an argon laser increased soybean yields by 30% on average compared to the control. The ratio of the yield from the main shoot to the yield from the lateral branches in this treatment was 40:60, indicating that pre-sowing stimulation of seeds had a significant and positive effect by increasing the yield of the lateral branches relative to the control. Stimulation of seeds (3 × 3 sec) with a helium–neon laser significantly increased protein content in soybean seeds, on average by 11% compared to the control. A longer duration of pre-sowing stimulation of seeds (3 × 9 sec) resulted in a significant increase in crude fat content in the seeds by an average of 5% compared to the control. The use of physical light stimulation on soybean seeds is a promising solution for increasing soybean yields.

The use of laser biostimulation technology in agriculture has thus far been limited to assessment of the effect of stimulation of seeds or seedlings on crop yield, mainly due to the technical limitations of the apparatus. Advances in mechatronics will enable broader application of laser biotechnology, for stimulation of plants in field conditions in order to minimize biotic and abiotic stress throughout their growth and development. This will increase productivity and improve crop quality, while reducing the use of pesticides, minimizing mineral fertilization, and increasing nutrient utilization by crop plants. Laser biotechnology can be used not only in agriculture, but also in energy production and environmental protection. More effective reclamation of degraded areas through biostimulation of plants can significantly increase the production of biomass as an energy raw material and contribute to the development of renewable bioenergy production (with no negative effect on food production) and the entire bioeconomy. Wider use of laser biotechnology can also contribute to more effective environmental protection and better exploitation of water resources by substantially increasing the efficiency of hydrobotanical wastewater treatment plants.

In the cooler regions of Europe, the success of winter pea cultivation depends strongly on proper plant development before winter. Previous research has suggested that plants need to develop short internodes and at least their first two leaves before the arrival of frost. However, this stage of growth is sometimes not reached in the event of late sowing, due to factors such as unpredictable weather conditions or the delayed harvest of a previous crop. An effective solution may be the application of plant growth regulators before the sowing of seeds. The aim of this study was to assess the seedling developmental characteristics of winter pea dependent on biostimulator applications in low temperature conditions (4°C). Seven different winter pea cultivars were treated with three biostimulants: Asahi SL, Kelpak SL, and Primus B. After 21 days of seedling development, basic biometrical characteristics were measured (length and weight of shoots and roots). It was found that ‘Enduro’ and ‘Aviron’ showed greatest root development, regardless of the applied biostimulants. The highest germination was achieved by ‘Aviron’. The efficiency of biostimulators on the cultivars tested was low, although slightly better results were found for Asahi SL in combination with ‘Enduro’ and ‘Aviron’.

... Although the mechanisms of LILR effect on plants are still a subject of discussion, it is widely used (currently, along with LED lamps) to stimulate growth and development processes in plant tissue in vivo and in vitro. At the same time, a positive (under certain conditions) effect of LILR on plants, including seeds, is considered to be proven [6][7][8][9][10][11][12][13]. However, the role of physical characteristics of radiation, as well as key compounds involved in the realization of the action of laser light, are still insufficiently studied. ...

... Because of the essential properties of lasers, like polarization and intensity, laser radiation has a strong potential for use in photobiology. These features of laser radiation make it valuable in the biological and agricultural domains, where it can have multiple effects on crop plants [8,11]. Certain progressions in plant height, fresh and dry weights, and biochemical up-regulation, such as proteins and starch contents of plants, are triggered after laser radiation [12,13]. ...

... Natural PBs appear as a potential category of agricultural inputs to improve the quality of horticultural plants, as well as enhance tolerance to abiotic and biotic stresses [1 , 2] . To date, a few PBs have been used during the cultivation of pea ( P. sativum L.) that contain marine algae extract [3] , micro and macro elements [4] , licorice root extract [5] and nitrophenols, nitroguaiaco [6] . Herbal drug-containing plant conditioning, general immunostimulant and yieldenhancing product Elice16Indures ( https://gynki.hu/en/rimph-botanicals/products ) and Fitokondi ( https://www.fitokondi.hu/a-fitokondi ) may have beneficial effects on plant growth and development and stress resistance. ...
