The aim of the present investigation was to study the growth, yield and yield components of maize (Zea mays L.) single cross 704 under different levels of irrigation, plant density, and ethephon in southern Iran where this particular crop has not yet been studied in detail. A field experiment was performed in the 2004 5 growing season at the experimental farm of the College of Agriculture, Shir...

The use of engineered nanomaterials has increased as a result of their positive impact on many sectors of the economy, including agriculture. Silver nanoparticles (AgNPs) are now used to enhance seed germination, plant growth, and photosynthetic quantum efficiency and as antimicrobial agents to control plant diseases. In this study, we examined the effect of AgNP dosage on the seed germination ...

in order to determinate the effects of plant densities in intercropped corn (zea mays l.) and bean (phaseolus vulgaris l.) on radiation absorption and use efficiency, an experiment was conducted at the agricultural research station, ferdowsi university of mashhad, iran during growing season of 2007-2008. this experiment was conducted in low input system. a randomized complete block design with ...

Ribosomal internal transcribed spacer (ITS) sequences were used to evaluate the phylogenetics of Zea and Tripsacum. Maximum likelihood and polymorphism parsimony were used for phylogenetic reconstructions. Zea ITS nucleotide diversity was high compared to other plant species, but approximately equivalent to other maize loci. Coalescence of ITS alleles was rapid relative to other nuclear loci; h...

People are worried about effect of household cleaning products in the environment. One of the sources of detergent is sewage that is being used for irrigation of the crops. A laboratory experiment and a pot experiment were conducted in 2012 to determine the effect of irrigation with different doses of detergent on plant growth and seed germination traits of maize (Zea mays). The experiments inc...

single and joint toxicity of chloramphenicol and hg acting on wheat (triticum aestivum l.), chinese cabbage (brassica campestris l.) and corn (zea mays l.) were investigated. the results showed positive correlations between root elongation inhibition of three plants and concentrations of pollutants added to soil (p
