for investigation quantitative and qualitative properties of different lines and cultivars of rapeseed, 19 selected lines from advanced inbreeding progenies, and zarfam variety (as check), totally 20 lines and varieties, were evaluated in a randomized complete block design with three replications at the experimental field of seed and plant improvement institute in karaj, during 2005-6. morpholo...

Performance of Chamomile (Matricaria chamomilla L.) was evaluated on twelve transplanting dates that were arranged at 30 days interval; during 2013-2014 on experimental field of Wondo Genet agricultural research center; using RCBD design with three replications. Transplanting time exerted a very highly significant (p<0.0001) influence on plant height, flower yield and essential oil yield; essen...

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...

Castor oil was extracted by mechanical cold pressing (< 45 0 C) of the seeds of wild castor plant (Ricinus communis L.) found in wet marginal lands of Katsina, Nigeria. Oil yield was 39.43%. The virgin oil (obtained as clear, viscous, pale-yellow liquid) was further purified by filtration through sintered glass (fine mesh screen). This was to eliminate any dust, gum, or other particulates prese...

Purpose: To determine the effects of temperature, pressure and extraction time on oil yield obtained from Polygonatum odoratum as well as the optimum processing conditions for supercritical carbon dioxide (CO2) extraction. Methods: Supercritical CO2 extraction technology was adopted in this experiment to study the process of extraction of volatile oil from Polygonatum odoratum while gas chromat...

this research was carried out to assess the effect of drought stress on head branch dry weight, photosynthesis, essential oil yield and radical scavenging of rosemary (rosmarinus officinalis l.) in islamic azad university, shoushtar branch, iran during 2010-2011.the experiments were carried out using complete randomized block design with four replications and drought stress levels included cont...

determination of the response of differentcrop varieties to environmental variables from planting to harvest is one of the fundamental pillars of agriculture planning to achieve maximum yield and desirable quality. changing planting date by effect on vegetative and reproductive growth period and balance between them, will affect yield and product quality. in order to study the responses of four...

in order to study the effects of drought stress on yield and yield components of safflower genotypes, a split plot based on randomized complete block design with four replications was performed at the research field, islamic azad university, arak, iran during summer of 2009. irrigation treatments included three levels of 100, 75 and 50% crop water requirement and four levels of safflower genoty...

Increasing attention is being paid to use of organic fertilizers such as manure and vermicompost which can increased yield and protect the environment. Replacing chemical fertilizers with manures has the benefit of low production cost and imparts beneficial effects on soil. Then an experiment was conducted during 2013 to measure effects of organic fertilizers on essential oil of dill (Anethum g...
