چکیده

In order to investigate the effect of humic acid on various aspects of the growth of the medicinal plant peppermint (Mentha piperita L.) in areas with alkaline soil, this research was conducted in Rafsanjan. This research is a randomized complete block design with four treatments (1- control (without using any fertilizer) 2- humic acid 50% (brand name bishumic) per hectare, 1000 kg (100 grams) per plot with dimensions of 1 m x 1 m) 3- Humic acid 40% (with the brand name Humi Green) along with 5% nitrogen, 2% phosphorus, 2% potash per hectare 1000 kg (100 grams per plot with dimensions of 1 m x 1 m) 4- 40% humic acid (with the brand name Humic Plus) along with 5% nitrogen, 5% phosphorus, 2% iron and 0.25% copper per hectare 1000 kg (100 grams per plot with dimensions 1 m x 1 m) ) in four repetitions, a total of 16 experimental plots were performed. After determining the location of each treatment, except for the control treatment, half of the determined amount of fertilizer was added to each plot (50 grams for each plot), then one irrigation was done and the seedlings were planted. The results showed that the amount of essential oil in the humic plus fertilizer treatment increased due to the increase in plant growth and the subsequent increase in dry matter. The amount of absorption of micronutrient elements such as iron, copper, zinc and manganese also increased.
