Abstract Background and aims Cadmium (Cd) contamination is a serious threat to plants humans. Silicon (Si) was reported have some alleviative effects on Cd stress in plants. However, whether Si alleviates toxicity maize genotypes with contrasting root system size are unknown. Methods Effects of application (200 mg kg ?1 soil) shoot growth, uptake transportation under (20 were assessed at the si...

This research aimed at investigating the effect of different levels of nitrogen and planting patterns on dry matter production and growth physiological indices in intercropping maize and sunflower. To do this a split plot experiment carried out based randomized complete block design with three replications in research field of Shushtar Islamic Azad University. The main plot included three level...

Effective, economical and feasible remediation technology of heavy metal pollution in farmland is an important research concentration the field soil remediation. In order to investigate effects formula fertilizer biochar on cadmium (Cd)–plumbum (Pb) contaminated farmland, blank (CK), lime (SH), (SWT), (FL), + (FS) were set up Cd–Pb farmland. The results demonstrated following: (1) Compared with...

background: heavy metals (hms) are one of the most important polluting substances emitted to the environment during cement production. tehran cement factory located in the southeastern of tehran, iran, closer to agricultural lands cultivates alfalfa, barley, and maize as feed. the objective of the study was to determine the concentration of hms in agricultural soils. methods: thirty six soil sa...

To determine the effect of nematode infection on the response of snails to selected toxins, we infected Helix aspersa with 0-, 0.25-, 1-, or 4-fold the recommended field dose of a commercial nematode application for agricultural use. In the first experiment, the snails also were exposed to cadmium via food and soil at concentrations of 0, 30, 60, 120, or 240 mg/kg in a full-factorial design. In...

controlled drainage is one of the strategies to reduce negative environmental effects in conventional drainage systems. this study examines the effect of controlled drainage on quality and quantity of drainage water, specifically amounts of salt and nitrate in drainage water, and nitrate uptake by maize (sc 704) with sandy loam soil texture in karaj. the experiment was performed as a randomized...

The Aim of this research is to examine the ability maize ( Zea mays ) accumulate heavy metals and assess bio-concentration factor (BCF) by collecting, analyzing data on metal concentrations in . This study assessed accumulation three selected metals; Copper (Cu), lead (Pb), Cadmium (Cd) soil corresponding Bio concentration grown those soils using a systematic approach.

The effluent from a Lucknow- based distillery (Mohan Meakin Distillery) was analyzed for physico-chemical and biological parameters of pollution and concentration of potentially toxic heavy metals (Cd, Cr, Ni and Zn) and the effect of the distillery effluent, as such and on 50% dilution with tap water was studied on seed germination and seedling growth of maize (Zea mays L.) and rice (Oryza sat...
