influence of cadmium toxicity on rice genotypes as affected by zinc, sulfur and nitrogen fertilizers

Influence of Cadmium Toxicity on Rice Genotypes as Affected by Zinc, Sulfur and Nitrogen Fertilizers

Cadmium (Cd) is among the most widespread and toxic heavy metal in several part of the world. Its toxicity in soil is becoming a severe threat to living organism worldwide. It is one of the main pollutants in paddy fields near industrial areas and highly toxic to plant growth and development of the plants. Cd can be easily taken up by plants and enter the food chain. Therefore, precautionary me...

Biofortification and Bioavailability of Rice Grain Zinc as Affected by Different Forms of Foliar Zinc Fertilization

BACKGROUND Zinc (Zn) biofortification through foliar Zn application is an attractive strategy to reduce human Zn deficiency. However, little is known about the biofortification efficiency and bioavailability of rice grain from different forms of foliar Zn fertilizers. METHODOLOGY/PRINCIPAL FINDINGS Four different Zn forms were applied as a foliar treatment among three rice cultivars under fie...

Influence of mineral and organic fertilizers on yield and nitrogen efficiency of winter wheat

The aim of this study was to evaluate the long-term (16-years) nitrogenefficiency after the application of organic and mineral fertilizers at two sitesLukavec (S1) and Suchdol (S2) with different soil and climatic conditions in theCzech Republic (Central Europe) and to determine grain yield and nitrogen contentwith regard to the requirements of protein content for baking quality of wheat.After ...

Interactive Effects of Cadmium and Zinc Application on Their Uptake by Rice Under Waterlogged and Non-waterlogged Conditions

In order to investigate the effect of Cd and Zn on uptake, concentration and the translocation factor of the Cd and Zn in the rice plant, a factorial experiment was conducted with four factors including two rice cultivars of Vandana and Hashemi, two waterlogged and non-waterlogged conditions and three levels of Zn and Cd (0, 5 and 10 mg kg-1 soil). The experiment was carried out in a randomized...

Combined toxicity of copper and cadmium to six rice genotypes ( Oryza sativa L . )

Accumulations of copper (Cu) and cadmium (Cd) in six rice cultivars (94D-22, 94D-54, 94D-64, Gui630, YY-1, and KY1360) were evaluated through exposure to heavy metal contamination (100 mg/kg Cu, 1.0 mg/kg Cd, and 100 mg/kg Cu + 1.0 mg/kg Cd) in a greenhouse. The dry weights of shoot and root, concentrations of Cu and Cd in plant tissues and the Cu, Cd, P, Fe concentrations in the root surface i...
