  Background and Aim: Food waste is one of the biggest challenges in today’s modern world and leads to greenhouse gas emissions and global warming issues. Converting organic waste into vermicompost and compost tea by efficient biotechnology methods could prevent natural resources depletion and decrease carbon footprint. These soil conditioners promote soil fertility, crop yields, soil resources conservation, and community health.Method: Based on this study, organic waste of the industrial kitchen of the science and research branch university, was converted to vermicompost. The compost tea was produced by a mixture of seaweed, vermicompost, molasses, and humic acid. Greenhouse studies to compare the effect of experimental treatments including irrigation level with compost tea 25, 50, and 100% and chemical fertilizer containing calcium nitrate, potassium sulfate, and 10-52-10 fertilizer on vegetative and biochemical traits of tomato (Karun variety) in six replications were performed.Results: The results showed that irrigation with 100% compost tea and chemical fertilizer, were not significantly different from each other and had the highest effect compared to other treatments. Irrigation with 100% compost tea had the greatest effect on leaf number (66 pieces), plant height (29.8 mm), root length (660 mm), and root fresh weight (29.84 mg). The highest number of flower clusters (8.94 clusters), root diameter (8.94 mm), peroxidase enzyme (3.5 µmol mg-1 protein min-1), chlorophyll a (14.44 mg g-1 FM), and total chlorophyll content (191.91 mg g-1 FM) obtained from 25% compost tea.Conclusion: There was no difference between irrigation with 25 and 100% compost tea, and chemical fertilizers. Furthermore, they had similar effects on most of the studied traits. So, irrigation with compost tea can decrease chemical fertilizers in tomato fields and leads to soil conservation.

  In order to evaluate the effect of organic and biological fertilizers on quantitative and qualitative characteristics of Melissa officinalis L. a factorial experiment was conducted in a completely randomized design with 4 replications in the form of open air pot conditions in Sari, in 2015. The factors examined included Mycorrhizal fungi (Glomus mosseae) (0 and10% of the pot volume), vermicompost (0 and 10% the pot volume), and compost tea (0 and 1.5 liter). Some characteristics such as number of flower, nitrogen, phosphorous, and potassium contents of aerial parts. Results showed that application of organic and mycorrhizal fertilizers had a significant impact on all measured characteristics and increased the number of flowers and fresh weight when compared with those of the control group so that the highest nitrogen concentration and the stem diameter were obtained from the combined mycorrhizal symbiosis, compost tea, and vermicomposting treatment.  The triple interaction effects showed that the absence of vermicompost with compost tea, and mycorrhizal symbiosis treatments increased the fresh weight compared to the control. Results also indicated that using vermicomposting, compost tea, and mycorrhizal symbiosis through the availability of nutrients increased the yield and improved qualitative and quantitative characteristics of Melissa officinalis L..

  Because of the importance of medicinal plants cultivation with organic manner and the advantages of biological fertilizers, the experiment was conducted based on completely randomized design with three replications in pot condition using three times at 10 days interval with foliar application of concentrations of 25, 50 and 100% vermicompost tea. Two weeks after the last spraying, canopy diameter, plant height, crown diameter, root length, node number, distance between the first node from the crown, leaf number, leaf length, leaf width, leaf fresh weight, shoot fresh weight, root fresh weight, plant fresh weight, leaf dry weight, shoot dry weight, root dry weight and plant dry weight were measured. The growth indices increased with increasing of concentration of vermicompost tea so that vermicompost tea 50% showed higher plant height, leaf number and plant dry weight. Vermicompost tea 100% treatment was the highest amount of root length, width and height of the leaf, stem fresh and dry weight, root fresh and dry weight. Vermicompost tea may have a positive effect on growth indices related to the ability of nitrogen uptake by plants or growth hormones effect of earthworms on vermicompost tea. Given the pace of the transfer of nutrients from the leaves to the different plant parts, spraying bio- fertilizers alone or in combination with chemical fertilizers can education in the cultivation of medicinal plants recommended less use of chemicals occurs, have a positive effect.
