introduction saffron as a food, spicy and medicinal plant has more than 62000 ha under cultivation with about 250 tons annual dry stigma production in iran, which includes about 90% of its world production. therefore, this plant has a specific value in agricultural export products of iran (fallahi et al., 2014). due to the important role of saffron in iran’s agroecosystems, the improvement of i...
A field experiment was conducted to evaluate the interference effects of wild barley (Hordeum spontaneum L.) on wheat (Triticum aestivum L.) yield, in 2009. The effects of different densities of wild barley (0, 25, 50, 75, 100, 125 plants m-2) in interferences with wheat at density of 300 plants m-2 were studied in a completely block design with three replications. Results showed that with incr...
to study the effect of different substrates on growth and yield of gerbera, this experiment was carried out as randomized completely block design with 14 treatments and 3 replications. treatments were as fallowing: fine sand, peat+fine sand (25%+75%), peat+fine sand (50%+50%), perlite+peat (75%+25%), perlite+peat (50%+50%), perlite+peat (25% +75%), perlite+peat+expanded clay (25%+70%+5%), perli...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
the effects of salinity and supplied calcium chloride on growth and leaf ions concentration of tomato (lycopersicon esculentum l.) were investigated in gorgan, iran. a factorial experiment was conducted based on rcbd with four nacl levels (0, 50, 100, and 150 mm) and four cacl2 levels (0, 100, 200 and 300 mg l-1). data of growth, yield and leaf’s ca, k, and na content were subjected to analyze ...
in order to determine the best traits related to indirect increasing of grain yield, five wheat genotypes (zagros, tajan, durum cul., kohdasht and n-81-18 line) were evaluated by using randomized complete block design (rcbd) with 4 replications in research field of gorgan university of agricultural sciences and natural recourses. the studied traits included leaf area index (lai), crop growth ra...
In order to evaluate the effects of sulphur fertilizer sources and amounts on growth indices and yield of peanut (Arachis hypogaea L. CV. NC2), a field experiment was conducted in Bandar Kiaashahr, Guilan province, Iran in 2004. The experiment was laid out in a factorial arrangement with two factors including sulphur sources (gypsum and single super phosphate) and sulphur rates (0, 30, 60 and 9...

Planting density, through its impact on the level of available environmental factors may have significant impacts on grain yield in safflower (Carthamus tinctorius L.). In order to investigate the impacts of plant density on grain yield, yield components and growth characteristics of safflower, a randomized complete block design field experiment with four replicates was conducted in spring-summ...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
