this experiment was conducted to improve the nutritive value of barley stubble for two consecutive years. after harvesting crop, at first year, a completely randomized design, with a 3 × 3 factorial experiment was conducted in which 27 plots were divided into nine treatments. the treatments including zero, 2.5 and five percent urea each with zero, three and six percent molasses were mixed with ...
To establish a high-efficiency system of isolated microspore culture for different barley genotypes, we investigated the effects of nitrogen sources and concentrations on callus induction and plant regeneration in different barley genotypes. The results showed that the organic nitrogen sources greatly increased the callus induction, and the great reduction of total nitrogen sources would signif...
in order to study the effect of planting pattern and nitrogen application on barley and faba bean yield and quality of forage in intercropping, an experiment was conducted on farm of agricultural and natural resources faculty of gonbad kavous university as factorial based on rcbd with three replications in 2012-2013. planting pattern consisted of five levels, i.e. sole barley, intercropping of ...
zero tillage practices have a direct effect on soil microbial communities modifying soil productivity and sustainability. the crop sequences used can change the aforementioned properties, too. in this study, we evaluated the effect of crop sequences under zero tillage management on soil biological and chemical properties including vertical distribution of soil organic carbon, soil basal respira...
An experiment was conducted to determine growth performance, carcass characteristics, and fat quality of growing-finishing pigs fed diets based on short-season corn hybrids. Twenty-four individually housed, Cotswold, growing pigs with an initial BW of 41.4 (SD = 1.4) kg were blocked by BW and sex and randomly allotted from within block to 1 of 3 diets to give 8 replicate pigs per diet. Experime...
The objective of this research was to evaluate the effects of monensin (MON), thyme (THY) and cinnamon (CIN) essential oils on dry matter and crud protein degradability characteristics of cottonseed meal, barley grain and corn silage, nutrient digestibility, and some plasma metabolites in Holstein steers (540 ± 35 kg initial BW) fed high-concentrate diets. Four rumen fistulated Holstein steer...
This study was conducted in acompletely randomized block design with three replications using three concentrations of 107, 105, and 103cfu/ml of Azotobacter isolated from the rhizosphere of Karun varieties of barley (Az. salentris) and standard Az.chrococom along with control (zero concentration of bacteria). The aim of this study was to study the reactions of barley plantin response to inocula...
the aim of this study was to investigate the effects of winter crops residues on weed control, physiological indices, yield and yield components of potato. an experiment was carried out at the research farm of colleg of agricultural of bu-ali sina university in 2009. the experiment was a randomized complete block design with three replications. residues of rye, oilseed rape, triticale, barley, ...

In order to determine the effects of using macaroni wastes instead of barley on dry matter intake (DMI), milk yield and composition, and nutrient digestibility, eight lactating Holstein cows (4 primiparous and 4 multiparous) in midlactation were used in a 44 Latin square design. The experimental periods were 21 d with 16 d for adjustment and 5 d for data collection. Treatments included a contr...
