  Introduction: Some of the post-harvest agricultural crops due to the improper maintenance of products, as well as damages caused by the pests might lose their quality. Therefore, the use of chemical compounds to increase the shelf life of fruits and vegetables might be inevitable. The aim of this research is to evaluate the effect of ozone, acetic acid and menthol on the shelf life and keeping quality of early Urbana Y tomato after harvesting. Materials and Methods: Tomato (Early Urbana Y variety) were subjected to different treatments such as ozonated water (0.2 ppm), acetic acid (0 and 4% V/V), menthol (0, 250 and 500 ppm) and combination solutions. Necessary experiments concerned with weight wasted, brix, sugar content, acidity, ascorbic acid content and microbial tests were carried out on the samples and the control. After 15 days of preservation in the environmental temperature, experiments were repeated and the influence of the treatments on the samples were determined and compared to the control. Results: The results indicated that the treatment caused the reducing sugar, waste and the microbial counts to be less than control after the keeping period, while the titratable acidity and ascorbic acid content in tomatoes were preserved better. Conclusion: Treatments affected the quality of tomatoes and the combined treatment; ozone, acetic acid and methanol at 500 ppm exhibited better effect. Manuscript profile

  The aim of this study was to investigate the effect of microbial inoculation on nutrient efficiency and quality of peppermint under drought stress in 2 crop years 2017-2018 and 2018-2019 in the Agricultural Research Center of Sarableh city located in Ilam province. This experiment was performed as a split plot in a randomized complete block design with 3 replications. Experiment with 2 factors, including drought stress in 3 levels of full irrigation (control), 70 and 50% of field capacity in main plots and growth-promoting bacteria and mycorrhiza in 6 levels including 1-control, 2-solute isolate Siderophore solvent + drought tolerant enhancer isolate, 3- mineral phosphate solvent isolate + drought tolerant enhancer isolate, 4- siderophore solvent isolate and drought tolerant enhancer isolate + dissolution isolate Mineral phosphate and isolates were increased by drought tolerance, 5-nitroxin commercial fertilizer and 6- mycorrhiza in subplots. The results of this study showed that most menthol essential oil in the combined treatment of siderophore soluble isolates and drought tolerant isolates + mineral phosphate soluble isolates and drought tolerant isolates and stress 50% of field capacity 24.2% was obtained compared to the lowest amount, ie control and full irrigation; Showed a 26% increase. At all levels of microbial inoculation except microbial fertilizer, the highest essential oil was always obtained at a stress of 50% of field capacity. The highest yield of peppermint essential oil was obtained in the treatment of commercial microbial fertilizer in the second year at the rate of 139.2 kg.ha-1. Microbial inoculation under stress at 50% of field capacity caused a 21% increase in dry shoot yield compared to the same level of stress in control. Growth-promoting bacteria and mycorrhizae increase quantitative and qualitative yield and increase the efficiency of nitrogen and phosphorus, which can have a significant effect on reducing costs and maintaining the ecosystem of agricultural systems.

  Biological fertilizers play a significant role in increasing the quantitative and qualitative yield of medicinal plants. In this research, the effects of vermicompost as well as nitrogen and phosphorous fertilizers were investigated on morphological traits such as height of plant and number of nod and quantitative and qualitative functions of peppermint essential oil. A factorial study was conducted as a pot experiment under the field conditions in a completely randomized design with 4 replications in 2017. Vermicompost treatment levels (consumption and non-consumption according to the manufacturer's recommendation) and nitrogen fertilizers and phosphorus (0, 50, 100, and 150 kg ha-1) were added to the  pot soils early at planting stage. The most essential components in the essential oil (more than 70%) were Alphapinene, Limonene, Izomenton, Menthol, 1, 8 Cineol, and Menton. Analysis of variations showed significant effectiveness of the treatments. Comparison of means suggested that the best treatments were application of vermicompost and nitrogen and phosphorus (100 kg. ha-1) that improved the morphological traits such as plant heights and number of nod and also the quality and quantity of essential oils. It seems that vermicompost increased morphological traits and consequently the amount and components of essential oil of the plant. Manuscript profile

  Peppermint (Mentha piperita L.) is an aromatic medicinal plant, that its cultivation is limited due to low soil from organic matter. Therefore choose right amount and type of fertilizer is very necessary to ensure of satisfactory yield. A factorial experiment was conducted at research farm of Ramin University during 2014, arranged in CRD design contain three types of nitrogen fertilizer as the first factor: liquid (urea ammonium nitrate), powder (ammonium sulfate) and granular (Urea) which were applied at five levels: 0, 70, 140, 210 and 280 KgN/ha as the second factor with three replications.  Aerial pares of plant were collected in early of blooming, the essential oils were obtained by hydro distillation method (Clevenger apparatus) and were analyzed by GC/MS. Result were showed that the nitrogen had significant effects on vegetative traits, quantity and  quality of essential oil and finally on  efficiency of nitrogen usage. With increases of nitrogen rate the vegetative traits and its yields of essential oil were increased. The effect of UAN was higher than U and SA, however, the trend of nitrogen usage efficiency was descended with AS of the lowest efficiency at 280 kg.ha-1. The rate and type of nitrogen fertilizers were also effective on essential oil components. The highest content of menthol was obtained in controls (37.16%) with 70 kg.ha-1 nitrogen (38.44%) but with increases of nitrogen application the menthol rate was decreased. Additionally, U and AS were respectively had the highest and lowest impact on menthol content, but in other hands the UAN application had the lowest content of menthofuran (1.17%). Manuscript profile

    Medicinal plants are of great value and importance in providing health care for communities in terms of treating and preventing diseases. Peppermint is one of the most important medicinal plants belonging to the Lamiaceae family which is cultivated worldwide today. Extensive research has been started to find out the effectiveness and effect of manure and biological fertilizers on the growth, yield and production of essential oils of medicinal plants which suggests improving the quality and quantity of the crops. In order to investigate the effects of livestock manure and biological fertilizers on peppermint mint, a factorial experiment in a completely randomized design with 4 replications was conducted in pots in Varamin region in 1396. Treatments included three levels of manure (0, 3 and 5 g cattle manure per 1 kg of soil) and four levels of biological fertilizers (no use, nitroxin, Barvar-2 and their composition). The results showed that the effects of livestock manure and biological fertilizer on the most of measured traits were significant. Comparison of mean of traits showed that usage of 5 grams of manure per one kg of soil, as well as biofertilizer application of nitroxin and Barvar2 had the highest significant increase in plant height, root length, fresh and dry weight of leaves per plant, fresh and dry weight of the plant, Chlorophyll b in leaf, essential oil content, nitrogen and phosphorus in leaf, essential oil yield and menthol content in essential oil compared to control; Therefore, the consumption of manure (5 grams of manure per one kg of soil) and use of the combined biological fertilizers are recommended for the highest growth yield, essential oil yield and menthol content.     Manuscript profile

  Mentha spp. are the main source of menthol essential oils. Medicinal plants sprayed with alcohols such as methanol and ethanol may cause vegetative growth and secondary metabolites improvement. The current study was carried out to evaluate ethanol and methanol foliar application efficiency on peppermint essential oils composition at Medicinal Plant Research Farm of Islamic Azad University, Miyaneh Branch based on randomized complete block design. One month aged peppermint plantlets were sprayed by 10, 20, 30 and 40% (v/v) ethanol and methanol aqueous solutions repeated twice two and four weeks after. The plants were harvested in flowering stage and their essential oils were extracted using hydro-distillation. The essential oils composition was specified using GC and GC-MS techniques. All phytochemicals in peppermint essential oils were significantly affected by hydroalcoholic solutions application but transpulegol, cis-pulegol, menthyl acetate, e-caryophyllene, α-himochalene and germacrene D. Plants sprayed by upper than 10% hydroalcohol solutions contained more menthol, significantly. Moreover, menthol amount was in higher values in the case of methanol application than ethanol. However, most of phytochemicals of peppermint were effectively promoted using ethanol 30%. Also, menthone and isomenthone negatively affected by methanol spraying in peppermint. Therefore, considering current research findings, methanol spraying is recommending to increase peppermint essence quality. Manuscript profile

  Peppermint (Mentha piperita L.) is one of the most important medicinal plants belonging to the Lamiaceae. In order to study the effect of different concentration of salicylic acid (SA) and salinity stress on peppermint morphological characteristics, an experiment was conducted as a factorial design based on completely randomized design with four replications. To investigate the interaction of salicylic acid and salinity stress, the following treatments were used: four NaCl concentrations of 0, 50,100 and 150 mmolL-1 and four salicylic acid 0, 0.1, 0.5 and 1 mmolL-1. The plants were grown in pots until they grow to harvesting stage. At the end of experiments, various traits such as height of plants, number of lateral branches, node and leaf, diameter of main shoot and shad of canopy, dry and fresh weight of shoot, fresh weight of root, length of internodes and root were measured. Plants that were under salinity stress level of 150 mmolL-1 died before end of experiments. The results showed that effects of salinity stress on number of lateral branches, number of node and leaf, shoot diameter, dry and fresh weight of shoot, length of internodes and root and fresh weight of root, SA on number of lateral branches and dry weight of shoot and their interaction on height of plants and shad of canopy were significant on peppermint. The highest suppress effect in salinity stress was obtained in 100 mmolL-1 NaCl and the effective in SA were 0.1 and 0.5 mmolL-1. Manuscript profile
