a trial study was set to assess the influence of the plant residue management in conjuction with application of different nitrogen sources on accumulation and translocation of wheat stem reserves, at the agricultural faculty of shahid chamran university of ahvaz during 2011-2012. the experimental design was split plot at randomized completed block design arrangement. the main plot were differen...

Remotely sensed estimates of crop residue cover (fR) are required to assess the extent of conservation tillage over large areas; the impact of decay processes on estimates of residue cover is unknown. Changes in wheat straw composition and spectral reflectance were measured during the decay process and their impact on estimates of fR were assessed. Proportions of cellulose and hemicellulose dec...

Anaerobic digestion is an optimal way to treat organic waste matter, resulting in biogas and residue. Utilization of the residue as a crop fertilizer should enhance crop yield and soil fertility, promoting closure of the global energy and nutrient cycles. Consequently, the requirement for production of inorganic fertilizers will decrease, in turn saving significant amounts of energy, reducing g...

to investigate the changes in yield and yield components of dry land wheat (triticum aestivum l. cv agosta), under the influence of residue and nitrogen levels and different tillage practices, a field experiment was conducted during the 2006-2007 growing season, in the agricultural research station of the college of agriculture, shiraz university, iran. the experiment was designed as a split-sp...

pesticides are one of the major pollutants in the environment. the residue of pesticides has been reported to be at a critical level in agricultural crops, especially in greenhouse crops. tomato is considered as an important vegetable in iranian food basket and is produced in fields and greenhouses. so, the current study aimed to assess diazinon and oxydemeton-methyl levels in tomatoes sampled ...

harvesting corn created annually a large amount of organic waste, which could be a suitable initial substrate for vermicomposting due to its high c/n ratio. the present study was aimed for recycling of corn residues and production of good quality vermicompost, after processing by eisenia fetida. the setup of experiments was conducted with 40, 60 and 80% of corn residue, compost, cow dung and pa...

A monoclonal antibody (3A5) that can recognize thiacloprid was produced, and a linear 8-residue peptide phage library was constructed. Six phage-displayed peptides were isolated from the linear 8-residue peptide phage library and a cyclic 8-residue peptide phage library. A phage enzyme-linked immunosorbent assay (ELISA) was developed to detect thiacloprid using a phage-displayed peptide. Under ...
