Enhanced soil fertility results in plant tolerance against environmental stresses, including drought stress. In order to investigate the effect of different fertilizers on biochemical, quantitative and qualitative characteristics of white radish under drought stress conditions, a split plot experiment was conducted as a randomized complete block design in 2020-21 at University of Hormozgan. Exp...

Biological indicators are considered soil quality elements, due to their dependence on soil organisms. In order to investigate The effect of compost and vermicompost enriched by chemical fertilizers and manure on soil organic carbon, microbial respiration, and enzymes activity in basil plant's rhizosphere, a field experiment was conducted as a split-plot design with randomized complete blocks a...

In order to investigate the effects of nutritional role of maternal-plant phosphorus (P) on seed production and quality of black seed (Nigella sativa L.) in a calcareous soil, three experiments were conducted at research greenhouse of Ferdowsi University of Mashhad, Iran, in 2012 and 2013. The first and the second experiments were conducted as a complete randomized design based on factorial arr...

A greenhouse experiment was conducted to evaluate the effect of vermicompost and sodium chloride (NaCl) on growth of spinach cv. Viroflay and some chemical properties of post-harvest soil. The greenhouse experiment was factorial, arranged in a completely randomized design with three replications. Treatments included three vermicompost levels (0, 1 and 2% w/w) and four salinity levels (0, 1, 2 a...

The first experiment was performed to evaluate the effect of vermicompost extract (20, 40, 60, 80, 100%) on seed germination and seedling growth of Plantago psyllium. In second experiment, the effect of solid vermicompost with 4 levels (0, 25, 50, 75) on the emergence and subsequent growth of plantlets was investigated. The 20 and 40% increased germination capacity, germination index, and lengt...

  Abstract   Background: Today, vermicompost production process as one of the very good procedures in terms of economic,health, and environmental sustainability to stabilize the organic waste is discussed. The aim of this study is vermicompost production from urban waste by earthworm (Eisenia Fetida) in Household-scale.   Methods: In this experimental study, plastic tank of vermicompost product...

Current study conducted to evaluate the effects of vermicompost and zeolite on the kinetics of nickel (Ni) fixation. Treatments consisted of a factorial combination of two vermicompost levels (zero and 2 w/w percent), three zeolite levels (zero and 4 w/w percent of zeolite of Firoozkoh, and Semnan) and two soil textures (clay and sandy loam) in three replications. All treatments were spiked wit...
