intercropping systems lead to reduce weeds population and their biomass. in order to study effect of marigold (calendula officinalis) and mungbean (vigna radiata) intercropping in different sowing times on yield and weeds control a factorial experiment based on randomized complete block design was performed in islamic azad university, tabriz branch, iran, during 2012 in three replications. stud...

to study the effect of plant density and planting pattern on iranian ox-tongue, an experiment carried out with two factors: planting pattern (square and rectangular pattern) and plant density (2, 4, 6, 8 plant m-2) in a factorial test performed based on rcbd in 3 replications during 2009-2010 in latmahalleh eshkevarat village in guilan province, iran. characteristics that measured included: dry...

To examine the genetic variation for drought stress in chamomile, eight accessions belonging to four species were evaluated under both field and greenhouse conditions using normal and late season drought stress. In the field experiment drought stress were initiated with irrigation cease at the commencement of flowering time. In greenhouse experiment, irrigation carried out at flower initiation ...

in order to investigate the effect of high density and depth of planting on agronomic characteristic of saffron, a field experiment was conducted as a complete randomized block design with three replications in faculty of agriculture, ferdowsi university of mashhad, iran during two growing seasons of 2008-2009 and 2009-2010. treatments were six levels of high densities (8, 11, 13, 16, 19 and 21...

throughout the present study some vegetative and reproductive characteristics of rosa damascene fewer than three different irrigation regimes (100, 70 and 40% of potential evapotranspiration) through an application of surface vs subsurface drip irrigation systems were investigated. some morphological characteristics investigated, included the number of branches per plant, shading diameter, plan...

using plant growth regulators at the stresses environment can improve plant growth and crop production. hence, in this research response of photosynthesis rate, chlorophyll, soluble sugar and flower dry weight of chamomile to methyl jasmonate under different salinity levels was studied. values of 0 (control), 75, 150, 225 and 300μm methyl jasmonate (meja) with salinity levels of 2, 6, 10 and 14...

several plant growth regulators are used to improve the quality of cut flower in bulb plants, but their effectiveness depends on genotype and plant growth conditions such as nutrition status. a pot experiment was conducted under farm condition to study benzyl adenine (ba) and potassium nitrate interaction on floret diameter, stem diameter, flower height, flower number per bulb, fresh and dry we...

in order to investigate the effects of soil texture and density on corm and flower yield of saffron (crocus sativus l.) an experiment was conducted as a factorial layout based on complete randomized block design with three replications at the faculty of agriculture, ferdowsi university of mashhad during two growing seasons of 2009-2010 and 2010-2011. treatment included 6 soil textures (clay loa...

in order to study the morphological characteristics affecting yield of echium amoenum under different nutritional treatments and different plant densities, a factorial experiment based on rcbd design with three replications was conducted at agricultural research station, ferdowsi university of mashhad, iran in 2011-2013 growing seasons. the experimental treatments were all combination of three ...
