decreasing water loss and increasing the irrigation times are basic methods to develop agriculture, success in natural recourse projects, minimize the stress to planted bushes in natural fields and increase the productivity of soil and water sources. the use of super absorbent is one of these strategies to achieve these goals. the main purpose of this research was to study the effect of super a...

abstract: one of the most important and complicated social transitions has been growth of worldwide urbanization. the rapid growth of urbanization and cities has had different consequences which is associated with much urban vulnerability. physical, installation, environmental, economical and social inequalities have been the results of such urban growth. this paper aims to study and identify t...

in order to evaluate the effects of drought stress and methanol foliar application on some quantitative and qualitative traits of soybean (cv. viliamz), a split plot experiment was conducted based on randomized complete block design at the faculty of moghan research farm in 2011. treatments were three levels of drought stress based on irrigation at depletion of 40, 55 and 70 percent of availabl...

green tea extract has plenty of antioxidant. due to the toxicity of synthetic antioxidants, it is necessary that these antioxidants in products such as donuts be replaced with natural antioxidants. the purpose of this research is to reduce the usage of synthetic antioxidants as it is possible. so the extract was extracted and it was used as a natural antioxidant in the dough of donuts. due to t...

this research was conducted to evaluate the effects of 1-mcp and ethylene on extending the display quality and increasing vase life of cut carnation flowers in a completely randomized design with three replicationsat the laboratory of the postharvest physiology, tarbiat modares universityin 2014. first, cut flowers were treated with 0, 0.5, 1 and 1.5 µl l-1 of 1-mcp for 24 h and then exposed to...

main objective in wheat breeding programs is to improve high yielding and stable varieties possessing desirable morpho-physiological traits. this study was conducted to determine the stability of 18 winter and facultative bread wheat genotypes. the experiments carried out in 9 experimental stations (karadj- arak- ardebil- jolgerokh- miandoab- hamedan- mashad- qazvin- khoy) using a randomized co...

in order to evaluate effect of azotobacter chroococcum strains on yield, yield components and qualitative indices of winter rapeseed (brassica napus l.), an experiment was conducted during 2009-2010 growing season at research institute of rice in rasht. the experimental design was completely randomized block, with three replications. investigated treatments were including control (without seed ...

plant analysis is successfully used in monitoring nutritional status, recommending fertilizer rates and types, and maximizing fertilizer efficiency in sugar beet. diagnosis and recommendation integrated system (dris) is a comprehensive approach which does not have limitations of the critical value approach (cva) and sufficiency range approach (sra). over- dose application of fertilizer increase...

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...

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...
