Abstract:

Parallelly with the importance given to the environment today, the use of microorganisms as an alternative instead of chemical fertilizers used in agricultural production is becoming increasingly important. This study was conducted in order to determine the effects of the application of microbial fertilizers in marul and white heads, which are among the most produced winter vegetables in our country, on grinding and fide development. As a plant material, the Green Wave marul variety and the Flaged-85 white head beans variety were used. The study applied 5 different doses of commercial microbial fertilizer called EM.5 (0, 5, 10, 15 and 20 mL L-1). The study found significant differences in the characteristics of the microbial fertilizer doses. According to the findings obtained from the research, the microbial fertilizer has been found to increase the grass rate, the fide length, the fide dry weight, the root dry weight and the proportion of dry substance, and the white headache has significantly increased the fide length, the fide age weight and the proportion of dry substance according to control. In general, the application of microbial fertilizers has been determined to have a positive impact on seed grinding and fide growth parameters. When the microbial fertilizer doses were evaluated, the 15 mL L-1 application was found to be more effective on grinding and fide development in both marulde and white headaches. Compared to the control application, the 15 mL L-1 application increased the fide length of the marulda by 35.71%, while the white head butter increased the fide age weight by 38.18%. The application of microbial fertilizer has been concluded that it can be successfully used as an alternative application method in increasing grinding and fide development in marul and white heads.
