“…They investigated the effect of nitrogen fertilizer on the growth and essence yield of peppermint and announced that dry matter and essence yield was significantly increased when nitrogen fertilizer applied. Not only the nitrogen element does not exist into the essence compound, but also it is involved in the chemical compound of some molecules like Protein, amino acid and nucleic acid [9]. The use of this element causes increasing extraction gland of essence at the leaves of peppermint [12].…”

“…These absorbable nutrients will be taken up by plants as soon as possible and will increase vegetative growth of plant. While, organic fertilizers will be decomposed into the soil by micro-organism gradually and released their nutrients slowly [9]. Thus, the content and content of nitrogen uptake by the plant at organic fertilizers is less than chemical fertilizers.…”

“…Niyakan et al [8] reported that wet and dry yield and also the content of essence as qualitative trait were increased using nitrogen and potassium elements at more content compared to the less content. The reason of the effect of nitrogen on wet and dry weight is existence of it in the chemical compound of some molecules like Protein, amino acid and nucleic acid [9,10]. Regarding to the effects of chemical and manure fertilizers on the qualitative and quantitative characteristics of medicinal plants, the present research is devoted more to the comparative study of chemical and manure fertilizers on yield, yield components and essence content of peppermint plant.…”

The current study examined the effect of chemical and organic fertilizers on yield components and essence content of peppermint (Mentha piperita L.). The experiment was carried out in randomized complete design with 7 treatments and 4 replications in Sari Agricultural Research Center, Iran, in 2013. Treatments were: 1-control, 2-sheep manure, 3-vermicompost, and basic chemical fertilizers at different contents as 4-N60,P50,K60 kg ha -1 which equals 0.24, 0.2 and 0.24 g per pot, respectively), 5-N60,P80,K60, 6-N90,P50,K80 and 7-N90,P80,K80. There were 28 pots that 10 kg soil was added to each of those and chemical fertilizer (at determined rates), sheep manure and vermicompost fertilizers (both at the content of 20 ton ha -1 equal 80 g per pot) were also added in per selected pot as treatment. The results showed that the effect of all treatments was very significant on the all agronomic properties and yield of peppermint. Some agronomic and quantitative traits of peppermint like plant height, number of chain, stem wet and dry weight, leaves wet weight and total wet and dry weight were obtained at the maximum values when basic chemical fertilizers was applied at the rate of 90-80-80. The maximum number of stems, number of flowers, number of suckers, leaves dry weight and essence content were also attained by sheep manure. Thus, to prevent soil, plant and finally environment pollution by using chemical fertilizers

“…These findings are in agreement with those reported by Niyakan [4], who reported that wet and dry yield and also the content of essence were increased using nitrogen and potassium elements. The positive effect of nitrogen on wet and dry weight was attributed to its chemical compound of some molecules like Protein, amino acid and nucleic acid [11,12]. So at the first harvest time, quantitative yield (wet and dry yield) was influenced by chemical fertilizers due to existent of more nitrogen (organic carbon= 28%) and potassium content in this fertilizer, and qualitative yield (the content and yield of essence) was affected when organic fertilizer especially sheep fertilizer was applied due to high in the fertilizer compared to other ones.…”

This study compared organic and chemical fertilizers on qualitative yield and essence content of peppermint. The experiment was carried out as Randomized Complete Design in Agricultural Farm Center, Sari, Iran, in 2013. The treatments were as control, vermicompost, composed sheep manure and basic chemical fertilizers at N60, P50, K60; N60, P80, K60; N90, P50, K80 and N90, P80, K80, and replicated four times. The results showed that all the measured characteristics were significantly (p<0.05) influenced by both organic and chemical fertilizers at the two harvest times. The values of the quantitative (wet and dry yield) and qualitative characteristics (essence content and essence yield) were also more at the first harvest than the second harvest. At the first harvest, the maximum value for dry and wet yield, and the maximum essence value and its yield were attained by using both sheep manure and chemical fertilizers at the rate of N90, P80, K80. The highest value for dry (96 kg ha-1) and wet (207 kg ha-1) yield, and yield (0.46 lit ha-1) and content of essence (0.48 g/100 g) were obtained with vermicompost. The values obtained for vermicompost and sheep manure were not significantly different. Application of sheep manure and vermicompost as organic fertilizer was recommended for production of peppermint. Whereas essence content and yield for first harvest were significantly higher than other treatments and control.

“…Organic fertilizer made positive changes in physical and chemical characteristics of soil and promoted the availability of the required nutrients for plants during the growing season (Khoramdel et al, 2008). It is reported that the slow releasing characteristic of animal manure prevents nutrients (N in particular) from leaching by excess water (Kolata et al, 1992). The chemical fertilizer had no significant impact on plant performance which could be explained by higher nitrogen leaching to deeper soil layers.…”

To study the effect of plant density and different nutritional systems (chemical, biological, and integrated) on the quantitative and qualitative performance of Thymus daenensis L. in Mahidasht Agricultural Training Center, Kermanshah/Iran, in 2017, an experiment was conducted in a split-plot design based on a randomized complete block with four replications. The first variable involved two planting distances in the row of 15 and 30 cm (the main factor), and the subsidiary factor comprised four different nutritional systems including control (no-fertilizer), chemical (100 kg superphosphate, 100 kg potassium sulfate, 150 kg urea per ha), biological (8 tons of cattle manure/ha), and integrated (50% cattle manure + 50% chemical) fertilizers. The results showed that the integrated fertilizer treatment produced the highest shoot dry weight (789.1 kg/ha), essential oil content (3.35%) and root length (15.97 cm). The integrated fertilizer treatment along with the 30-cm planting density resulted in the highest essential oil content of 3.35%. The results of this project have suggested that the integrated fertilizer and the 30-cm planting interval is the optimal treatment in thymus production due to the higher chemical fertilizer efficiency and better crop quality.
