in rainfed areas of iran, cereal yields are low, variable and mainly as a result of inadequate and erratic seasonal rainfall and associated management factor, such as late sowing date (or late crop germination). in order to investigate the effects of single irrigation and nitrogen on bread wheat (triticum aestivum l. var. sabalan) a field experiment was conducted as split plot arranged in a ran...

in order to determine the lipids and lipoproteins profiles in iranian khouzestanian arab horses, blood samples were collected from the jugular vein of 77 horses(47 female, 30 male) from different age groups(< 6, 7-12, 12-36, 37-60, 61- 69 and > 96 months). serum cholesterol and triglyceride were measured by enzymatic methods and lipoproteins by precipitation methods. the results were analyzed b...

in order to study the interrelations of photosynthetic rate and surfaces and leaf proline content with yield and yield components of safflower under different irrigation regimes, a field experiment in a split plot arrangement under a ranomized complete block design with four replication was performed at lavark reasrch farm, isfahan university of technology, isfahan, iran in 2007. two irrigation...

the study of spatial and temporal changes in climate parameters, is one the most important issues in the world&apos;s climate research. study of changes in cloud cover as one of the most important climate parameters is important, because clouds are in top of hydrologic cycle and changes in them make changes in spatial and temporal variations in other climate parameters. in this study, the spati...

to compare the nutritional value of rapeseed meal and cottonseed meal in holstein cows, feeding 20 lactating holstein cows each with an average weight of 580± 34 kg and 100± 10 days in milk were studied in a randomized complete block design. the experimental diets consisted of 4 levels of 0, 8, 14 and 25 percent rapeseed meal replaced with cottonseed meal and barley grain in the diets. diets we...

effects of different k/ca ratios on the growth, yield and physiological characteristics in galia (cucumis melo var. reticulatus l. naud. cv. galia) grown in hydroponics were evaluated. the experiment was arranged in a completely randomized design of three replicates. melon seeds were sown in a medium containing perlite and vermiculite (3:1 v:v) and then irrigated with water containing different...
