Copper (Cu) accumulation in shoot and root tissues and low molecular weight organic acids (LMWOA) root exudation have been studied in two metallophytes from Central Chile (Oenothera affinis and Imperata condensata) and two agricultural plants (Lupinus albus and Helianthus annus) growing under hydroponics conditions at increasing Cu levels (0, 0.125, 0.250, 0.5, 1 and 2 mg Cu/L). The plants were...

Experiment was conducted during 2007 growing seasons at the Field of College of Agriculture, Tarbiat Modares University, Tehran Province, Iran to study the effect of biofertilizers (Azosporillum and Azotobacter), nitrogen fertilizer (N) and farmyard manure (FYM) in various rates on the grain and biological yield, seed protein content as well as seed oil content and fatty acid composition in sun...

The effects of plant species (castor bean (Ricinus communis L.) versus sunflower (Helianthus annus L.)) and irrigation regime (freshwater versus secondary treated municipal wastewater) on soil properties and on seed and biodiesel yield were studied in a three year pot trial. Plant species were irrigated at rates according to their water requirements with either freshwater or wastewater effluent...
