In terms of the comparative study of the evolution of beans plants in the electromagnetic field, the accomplishment involved quantifying the development strains lengths, beans and pods production, dry matter content of plants, in greenhouse conditions, namely in the "House of Vegetation" of University of Agricultural Sciences and Veterinary Medicine Cluj – Napoca, in the experimental year of 2016. The process of strains growing, one month after the establishment of culture, under greenhouse conditions, highlights a superior development, statistically ensured at a 0.1% threshold of significance, , even control, when plants were placed under electromagnetic field. Two months after sowing, the growth process of beans streams under greenhouse conditions, shows a higher development statistically ensured at different thresholds of significance when plants were placed under electromagnetic field. In the absence of irradiation, two months after sowing, the length of the stems was located between 17.13 cm-20.06 cm. Under electromagnetic field, the bean plants, had one month after sowing lengths in the range of 24.06 cm - 27.13 cm. The average length stems recorded at the untreated control variant, equal to 24.06 cm differs significantly from that reported in the absence of irradiation (p <0.001), as well from the average length, equal to 27.13 cm recorded at the experimental variant. A larger number of pods is obtained at irradiated plants compared with those placed under electromagnetic field, the control one, is identical, equal to 6.40 pieces, but in the absence of the electromagnetic field. The evolution of the average number of beans in the present experiment has an identical trend with that recorded in the production of pods. At bean plants grown under greenhouse conditions, the bean production records differences, uninsured statistically at 5% threshold, between the quantity of beans obtained from plants placed under the electromagnetic field and from the non-irradiated plants, but statistically ensured differences at 5% threshold are recorded between the quantity of beans obtained from plants placed under the electromagnetic field and from irradiated plants. In the present study, it can be noted that increasing the quantity of beans production positively contributes to the increasing of the number of pods, and to a lesser extent, by almost a third, the increasing of strains length causes a decrease in the amount of beans production.
