abstract this study is carried out to determine the chemical composition in the three vegetative stages of the haloxylon sp., degradation parameters, with adding naoh and ca(oh2 ). for this purpose, in may and october and january 2010 enough some haloxylon sp. of the ammary area was prepared. crude protein and ash percentage are decrease, neutral detergent fiber percentage with pragress stage ...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
Grain yield of bread wheat (Triticum aestivum L.) is reduced by heat stress, particularly when occurs in reproductive phase, in many countries worldwide, including Iran. In order to study the effects of different levels of nitrogen and cytokinin on wheat yield and yield components at normal and heat stress conditions in Khuzestan, Iran, this research was conducted at Ramin Agriculture and Natur...
abstract the objective of this study was to assess the effects of few arbuscular mycorrhizal fungi and plant growth promoting rhizobacteria on the growth and yield indices of two wheat varieties in a saline soil (ec=10/1 dsm-1). a factorial experiment with completely randomized design with four replications was conducted to investigate the effects of three levels of fungal inoculation (non inoc...
To investigate the effect of nitrogen and zinc elements on the quantity and quality characters of sunflower plants (Jamah1cultivar), a factorial experiment in a randomized complete block design with three replications was conducted at the University of Zabol, Zabol, Iran in 2013. The experiment consisted of three nitrogen levels: 100, 200 and 300 kg ha-1 as the first factor and three levels of ...
the objective of this study was to evaluate the effect of plant population and nitrogen rate on yield and yield components of corn (zea mays l, hybrid 704) in 2008 at mamasani region, fars province. the experiment was conducted as a factorial based on randomized complete block design with three replications. experimental factors was four plant population (75000, 90000,105000, and 130000 plant h...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
Salt-alkali is the main threat to global crop production. The functioning of phosphorus (P) in alleviating damage to crops from saline-alkaline stress may be dependent on the variety of crop but there is little published research on the topic. This pot experiment was conducted to study if P has any effect on rice (Oryza sativa L.) yield, dry matter and P accumulation and translocation in salt-a...
this study was carried out to determine nutritive value and the effect of amaranthus grain on performance and carcass characteristics of broiler chicks. chemical composition of amaranthus grain including dry matter, crude protein, crude fiber, crude ash, and gross energy were 91.04, 17.50, 8.40, 2.70, 5.41, percent and 4515 kcal/kg respectively. metabolizable energy content of amaranthus grain ...
To evaluate effect of different irrigation regimes and mycorrhizal fungi on the growth and yield of mungbean NM92 [Vigna radiata (L.) Wilczk], a field experiment was conducted in split plot arrangements using randomized complete block design (Irrigation after 50, 100, 150 and 200 mm evaporation from pan class A as main plots and mycorrhiza species, Glomus mosseae, G. intraradices and a non-inoc...
