for investigation deficit irrigation and nitrogen application effect on nutrients uptake of henna ecotypes, this research was conducted in the form of split-split-plot on the basis of randomized complete block design with four replications in the research field of islamic azad university, jiroft, iran in 2013-2014. the main, sub and sub-sub plot were deficit irrigation (100, 75 and 50% of crop ...
from a total of 656 broiler farms with the permission of exploitation in guilan province, data was gathered from 20% of active farms including 85 units (capacity of over 1663000 portions of broiler chickens) to evaluate the management of nutrition and nourish using questionnaire. the questionnaires were completed by the interview method. the methods of making feed, feed formulation, the shape o...
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
the present research was conducted to accomplish two purposes. firstly, it aimed to explore and describe schematic structure or what halliday and hassan (1989, p.64) have called “generic structure potential” (gsp) of american english, iranian persian and iranian english newspaper editorials within systemic functional linguistics. secondly, a quantitative cross-comparison was made to investigate...
In any breeding program, knowledge of the nature of gene action involved in the inheritance of traits is a basic requirement. In this research, diallel crosses progenies of six coriander landrace were evaluated in F1 and F2 generations. The genotypes were evaluated in different irrigation conditions in three separate experiments, in which each experiment was conducted in a randomized complete b...
a field study was carried out at the islamic azad university of arak in 2010 to find out the effects of salicylic acid and water deficit stress on oil yield and some physiological characteristics of different varieties of sunflower. the experiment was laid out in a factorial split plot based on a randomized complete block design with four replications. treatments consisted of water stress in th...
This research was conducted at the research field of West-Azerbaijan (Saatloo station, 45° 10′ 53˝ E/ 37° 44′ 18˝ N and 1338 m above sea level), located 25 km from Urmia city (Iran) during 2019-2020 cropping seasons, as a factorial layout based on randomized complete block design with three replications. The first factor was irrigation regime at three levels (supplying 100, 75 and 50% of net ir...

Soil amendments have been widely used in greenhouse cultivation. Cucumber, as an important summer crop, has the highest area under cultivation in the greenhouses of Iran. For this reason, in the present research, effect of applying zeolite and drought stress on cucumber growth and its fruit parameters (number, weight, length and diameter of the fruit) was investigated in a split-plots experimen...
