INFLUENCE OF ELECTROMAGNETIC FIELD AND BACTERIA ON SPRING WHEAT BIOMETRIC PARAMETERS

Abstract

As human population is rising, food demand is rising as well. One of the ways to fulfill this demand is to increase crop yield by using electromagnetic field (EML). EML may increase various plant growth parameters such as germination, shoots growth and mass, chlorophyll and nitrogen concentrations in plant leaves. Another way might be usage of various bacterias. Bacillus spp. bacterias improves crop growth in direct and indirect ways through nitrogen fixation, phytohormones, as making resistance against diseases for plants. The study investigated how spring wheat seeds of “Hamlet” variety respond to 24-hour exposure to EMF, usage of Bacillus toyonensis, Bacillus megaterium and Bacillus Licheniformis and also using combinations of EMF and bacteria. The effects of spring wheat biometric indicators (assimilation area of leaves, aboveground and root mass) and chlorophyll with nitrogen concentrations were studied. Leaf area was measured using the Win Dias program, chlorophyll concentration in leaves measured with the MC-100 device and nitrogen content was measured using the PlantPen. The results were statistically processed using the DISVEG plugin of the Selection program. The highest results were generally obtained using combinations of EMF and bacteria. When comparing the use of EMF alone, it is seen that the results using EMF are insignificantly but greater than without using EMF, except for the result of nitrogen concentration in leaves, which was significant.
