abstract genetic diversity of german chamomile (matricaria chamomilla l.) populations in iran was evaluated using morphological, agronomical and phonological characteristics and compared with three cultivars from germany, hungary and iran. in this experiment, statistical design of rcbd with three replications was used, sixteen quantitative traits were measured such as yield, flower number per p...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
for optimum utilization of saline soil and water resources, various methods have been proposed. application of best management practices and selection of salt tolerant cultivars are two important issues. selection and breeding for salt tolerant cultivars require potential genetic materials, screening and evaluation of them in laboratory and field experiments. starting in 2000, 80 sugar beet gen...
High yielding crop production technologies became available for farmers in irrigated favorable agricultural ecosystems from 1960’s known as Green Revolution, while 77% of world arable land (~1,086Mha in 2014, FAOSTAT) is estimated without irrigation and prone to water shortage or drought (a disaster from a shortage of rainfall and available water on agriculture and other human lives). Greater d...
in order to study the effect of solitary and combined application of two types of green manure, cow manure, barvar-2 phosphate fertilizer and conventional chemical fertilizer on some of the qualitative and quantitativeproperties of sugar beet, an experiment was conducted at the research farm of shahrekord university in 2013. the experimental design was randomized in a complete block design with...
The adaptations of root morphology, physiology, and biochemistry to phosphorus supply have been characterized intensively. However, characterizing these adaptations at molecular level is largely neglected under field conditions. Here, two consecutive field experiments were carried out to investigate the agronomic traits and root traits of wheat (Triticum aestivum L.) at six P-fertilizer rates. ...
abstract this research has been carried out with the purpose of investigating the conditions and related elements of the employment of the educational sciences graduates of hamedan province universities in 1382-1387 academic years. it has been a descriptive research of a correlation kind, and the population number has been 1180 grduates of payam- e noor universites in asad – abaad, kaboudaraha...
Chickpea, the second most important legume crop, suffers major yield losses by terminal drought stress (DS). Stronger root system is known to enhance drought yields but this understanding remains controversial. To understand precisely the root traits contribution towards yield, 12 chickpea genotypes with well-known drought response were field evaluated under drought and optimal irrigation. Root...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
in order to evaluate salinity tolerance in 20 sugar bee genotypes, an experiment was conducted in two fields with salinity (ec= 12 ds/m, ph= 7.6) and non-salinity stress, in the form of rcbd at miandoab agricultural research station. different morphological and physiological traits such as root yield, sugar percentage, white sugar percentage, molasses, n, na, k, syrup purity and green cover per...
