Experiments were conducted to remove heavy metals (Cr, Cd, Pb, Cu and Zn) from urban sewage sludge (SS) amended with spent mushroom compost (SMC) using worms, Lumbricus rubellus, for 105 days, after 21 days of pre-composting. Five combinations of SS/SMC treatments were prepared in triplicate along with a control for each treatment in microcosms. Analysis of the earthworms' multiplication and gr...
Scientific investigations have established the viability of using earthworms as a treatment technique for numerous waste streams besides producing organic fertilizers. Vermicomposting results in the bioconversion of the waste stream into two useful products, earthworm biomass and vermicompost. The former can be used as a protein source whereas vermicompost is considered as an excellent product ...
in order to study the effect of vermicompost individually and enriched with chemical fertilizer on soil micronutrient content and micronutrient concentration of lettuce (lactuca sativa l.), athree year experiment was conducted with randomized complete block design in two factors and three replications at the experimental farm of sari agricultural sciences and natural resources university in 200...
Smoke tree (Cotinus coggygria Scop.) is an attractive ornamental tree in landscape that has medicinal properties. In this study, the effects of different levels of salt, cow manure and vermicompost on plant growth were investigated. In a factorial experiment and completely randomized design (CRD), three levels of organic amendments (1- soil 2- 80% v/v soil + 20% v/v vermicompost, 3- 80% v/v soi...
two separate experiments were carried out with the aim of investigating the effect of vermicompost and its aqueous extracts on traits related to germination and growth of tomato varieties, (mobil and superorbina). in the first experiment, 0.5, 1, 1.5, 2, 2.5, 5, 7.5, 10 and 100% extracts of vermicompost (v - v) along with control (distilled water) were studied on germination of two varieties of...
Organic fertilizers in sustainable agricultural system are causing yield stability, especially in production of medicinal plants. Also consideration to forgotten medicinal plants such as Zuleng (Eryngium caucasicum Trautv.) that the leaves contain essential oils is most important because of the rich genetic potential. In order to evaluate the effects of different organic and chemical fertilizer...
In the current research, the simultaneous application of 0, 5 and 10 tons per hectare of vermicompost organic fertilizer and biochar on growth and grain yield of Camelina sativa as a factorial experiment based on a randomized complete block design with three replications in East Azarbaijan province (crop year 2020-2021) was evaluated. The highest oil yield (1073 kg/ha) was obtained in the appli...
This study was performed to investigate interactions of different levels of vermicompost extract and salinity stress on germination characteristics of chickpea seedlings. The factorial experiment was conducted in completely randomized design with three replications. Concentrations of vermicompost extract (0, 5, 10 and 20 volumetric percentage) and salinity levels (0, 30, 60 and 90 mM NaCl). Res...
The purpose in this research was to study the effects of Vermicompost and poultry manure on yield and yield components of the medicinal plant coriander (Coriandrum sativum L.) in the Shahr-e- Ghods region. A factorial experiment using the randomized complete block design with three replications was conducted in the Islamic Azad University of Shahr-e- Ghods. The first factor was three levels of ...
