BACKGROUND: Wheat produces more than 50 percent of requirements protein and calorie for human nutrition in Iran. Management of nitrogen fertilizing is important to increasing wheat production. So, among chemical fertilizer a high correlation reported between nitrogen and yield. Also to improve physical, chemical and biological properties of soil, organic fertilizer such as verm...

to study the effect of vermicompost and urea and iron sulfate fertilizers on the growth characteristics and yield of sunflower seed (helianthus annuus l.) an pediment was conducted in darreh gaz located in khorasan razavi province in 2012. factorial experiment in a randomized complete block design with three factors and three repetition. in this experiment three levels of urea (50; 150 and 250 ...

This study investigated the effects of the sawdust vermicompost extract (aqueous extract) on yield and chemical quality of Dracaena marginata var.‘Tricolor’ grown under four sawdust vermicompost extract solutions (0, 250, 500 and 1000 ppm). The sawdust vermicompost extract was prepared using non-aerated extraction methods with 1:10 (v/v) of sawdust vermicompost to water and was sprayed three ti...

BACKGROUND: Management of water deficit is a great factor to sustainable crop production, especially in arid and semi-arid regions. Vermicompost is an organic compound that is microbial active and rich in nutrients that results from the interaction of earthworms and microorganisms with organic matter decomposition. OBJECTIVES: This research was carried out to ...

organic compost can reduce various plant stresses, because of its porous structure, high water storage capacity, and existence of some substances resembling hormones and plant growth regulators. this study was performed to investigate interactions of different levels of vermicompost extract and salinity stress on morphological characteristics of bean seedlings. the experiment was conducted in c...

BACKGROUND: Management of nutrients, especially nitrogen, in order to have economic production, maintain sustainable agriculture and provide food security, is considered to have an important priority. OBJECTIVES: Current study was conducted to evaluate effect of different level of nitrogen fertilizer and vermicompost on quantitative and qualitative traits of w...

The objective was to evaluate the effect of tannery sludge vermicompost in the chemical properties of soil cultivated with tomato and irrigated with wastewater. The experimental design was completely randomized in a factorial 6 × 2, totaling twelve treatments with three replications. The treatments were: four tannery sludge vermicompost (25% Sludge tannery(LC) + manure T1, 25% Sludge tannery(LC...

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 ...
