بررسی تاثیر کودهای شیمیایی و زیستی بر عملکرد و درصد اسانس نعناع فلفلی

In order to investigate the application of chemical and biological fertilizers on quantitative and qualitative traits of peppermint plant a split plots in time with two factors in experiment randomized complete blocks design with four replications conducted in research farm of the University Campus and Natural Resources Tehran (Karaj), was implemented in ۲۰۱۹. The first factor of chemical and biological fertilizer treatment at ۱۳ levels (A۱= nitroxin fertilizer (۵kg/ha), A۲= nitroxin fertilizer (۱۰kg/ha), B۱=supernitroplus fertilizer (۵kg/ha), B۲= supernitroplus fertilizer (۱۰kg/ha) ), C۱=biosulfur fertilizer (۵kg/ha), C۲=biosulfur fertilizer (۱۰kg/ha), D۱=superphosphate fertilizer (۵kg/ha), D۲= superphosphate fertilizer (۱۰kg / ha), E۱= urea fertilizer (۷۵kg/ha) ), E۲= urea fertilizer (۱۰۰kg /ha), F۱= iron fertilizer (۱kg/ ha), F۲ = iron fertilizer (۱.۵ kg/ha), S=control (without fertilizer), and the second factor was harvest time in two cutting times. The experimental results showed that application of biochemical fertilizers significantly increased all quantitative and qualitative traits (height, length and number of inflorescences, wet and dry yield, leaf area, percentage and yield) of essence plant significantly ۱% probability level. Treatment of biochemical fertilizers improved the quantitative and qualitative traits of peppermint compared to the control treatment (without fertilizer). The tallest height, length and number of inflorescences, wet and dry yield, leaf area, percentage of essential oil in the first harvest obtained in nitroxin biofertilizer treatments at ۱۰ kg/ha and urea chemical fertilizer at ۱۰۰ kg / ha. Also, the highest amount of the above traits in the second harvest was related to nitroxin biofertilizer at the rate of ۱۰ kg/ha. The lowest amount of all quantitative and qualitative traits of peppermint obtained in the first and second harvests in the control treatment (without fertilizer).
