Heavy metals contamination is a major environmental problem which requires immediate human attention. The use of plant species to remove pollutants from soils, generally defined as phytoextraction. In order to evaluate phytoextraction of contaminated soils, a pot experiment conducted using two plants Barley, Canola three kinds of heavy metals (Cd, Pb, Ni) with 3 levels in a completely randomize...
In this experiment 36 accessions of seven species of Brassica genus were evaluated under field condition (for study of genetic variation) and under laboratory condition (for study seedling drought tolerance) in 2012 at Isfahan university of technology research farm. The statistic design in field was completely randomized block with three replications. Results of field assessments were suggestiv...
optimizing the herbicide dose by the addition of adjuvants is an acceptable way to increase performance and to reduce the risk of side effects from herbicides. therefore, to detect a suitable adjuvant for clodinafop-propargyl against little seed canary grass (phalaris minor retz.). greenhouse experiment were conducted as factorial in completely randomized design with four replications for compa...
A ten-week experiment was conducted to study the effect of a nanostructure of phytic acid absorber (NPAA) on the performance and protein digestibility in laying hens. A total of 100 Bovans laying hens were randomly assigned to 5 treatments, with 4 replicates, 5 hens each. The experiment was a completely randomized design with 5 levels of NPAA; including zero (T1, as a basal diet (BD)); T2 (BD+ ...
A completely randomized experimental design was conducted to estimate ammonia excretion rate by red tilapia (Oreochromis sp.) during different stages of its growth in recirculating water system units typically designed to meet the experiment purposes. Eight weight groups each containing 75individuals of 20, 30, 40, 60, 80, 120, 180 and 200g average weight were considered as treatments in duplic...
The mechanism of compensatory growth in rainbow trout (Oncorhynchus mykiss) was studied in a completely randomized design with four experimental treatments and a control group (no food deprivation) with three replicates. Animals in treatments 1 to 4 were fed with rates of 0, 25, 50 and 75% saturation, respectively for two weeks. Then, the treatments were fed twice a day until saturation level f...
The effects of Trigonella foenum graecum (TF) and Foeniculum vulgare (FV) seeds powder on antimicro-bial activity and performance of broiler chickens were studied. Based on a completely randomized design, 240 broiler chicks (Ross 308) were assigned to 4 treatments and 4 replicates. The treatments were a basal diet (control, T 1), T 1 plus 0.5% TF (T 2), T 1 plus 0.5% FV (T 3) and TFFV (0.25% TF...
A 4 days study was conducted to determine the effects of Different concentration of bioaugmentor bacterial strain Bacillus licheniformisi, B. subtilis, B. polymyxa, B. laterosporus and B. circulans (Protexin Aquatech, UK) on adjustment of parameters of water quality as TAN, NO2-N, NO3-N and turbidity from the effluent of Common Carp ponds. Effects of time and concentration were studied as a com...
The aim of the study was to compare the growth performance and carcass quality of layer-type cockerels and broilers reared under identical conditions. A total of 180 one-day-old broiler male (BM), broiler female (BF) and brown layer male (LM) chicks were distributed into 9 floor pens in a completely randomized design, with 3 replicates of 20 birds per experimental unit. The body weights and fee...
