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...

high moisture levels in fresh dairy manure provide a suitable environment for growth of pathogens and cause environmental pollution. dry manure can be used for different purposes in agriculture and in livestock industry. such heat properties of manure as specific heat, thermal conductivity and thermal diffusivity are important needed factors for the design and development of a suitable efficien...

in order to investigate the effects of different irrigation regimes and zeolit on the yield, yield componentsand relative leaf water content of sorghum, a field experiment was conducted in split plot in time andspace based on randomized complete block design with three replicates in research station of shahidbahonar university of kerman in 2011. irrigation regimes (100, 80, 60 and 40% of field ...

in order to evaluate the effect of different mechanical treatments (application of sulphuric acid, boiling water and flooding) on seed dormancy breaking of licorice, an experiment was carried out in randomized complete block design in 2012. moreover, a factorial scheme in rcbd was performed to assess the application of giberalic acid and potassium nitrate treatment as well as stratification and...

in order to investigate the effect of different irrigation regimes on yield and leaf proline content of a spring isfahan local variety of safflower, a field experiment was conducted as split plot in randomized complete block design with three replications at the research station of shahrekord university in 2013-2014. the main factor consisted of four different irrigation regimes (irrigation aft...

soil compaction is one of the most prevailed limitations for crop growth. the use of organic matters as fertilizer on agricultural soils can reduce the effects of soil compaction and provide the nutrients for the plants. so, a factorial experiment was carried out in a randomized complete blocks design with three replications. the first factor was the source and amount of organic fertilizer (far...
