To evaluate the effect of soil salinity stress on some vegetative and reproductive traits of sunflower (Helianthus annus L.) oil varieties in Mahabad conditions, a factorial experiment was conducted in greenhouse condition based on randomized complete block design with five replications in 2009. Treatments were included five levels of soil salinity (EC: 0.5 (as control), 2, 4, 6 and 8 ds /m) an...
Many traits play essential roles in determining crop yield. Wide variation for morphological traits exists in Hordeum vulgare L., but the genetic basis of this morphological variation is largely unknown. To understand genetic basis controlling morphological traits affecting yield, a barley doubled haploid population (146 individuals) derived from Clipper × Sahara 3771 was used to map chromosome...
in order to study of the effect of seed inoculation with pgpr on nitrogen and phosphorus use efficiency of spring wheat in different levels of nitrogen and phosphorus fertilizers, an experimental was conducted at the research farm of mohageh ardabili university, ardabil, iran during 2012 year. the combination of nitrogen fertilizer in three levels (0, 40 and 80 kg n/ha as urea) and phosphorus f...
Identifying selection indices is the most important step of a breeding project that aims to improve grain yield. The definition of the selection index is usually done by evaluating the variables in multivariate statistical methods. In the present study, the relationship between grain yield and its components in bread wheat genotypes was determined by multivariate statistical methods. The experi...
In order to study the effects of different levels of irrigation, nitrogen and plant population on yield, yield components and reserved dry matter remobilization of seed corn (SC. 704 hybrid) a research was conducted at the experimental field in Khuzestan Natural Resources and Agricultural Science University in summer, 2004. This research was made based on three split-plot field experiments, R...
In order to study the effect of irrigation withholding and biofertilizers application on quantitative and qualitative yield and grain filling duration of sunflower (Helianthus annus L.), a factorial experiment was conducted based on randomized complete block design with three replications in research field of Faculty of Agriculture and Natural Resources, University of Mohaghegh Ardabili, Iran i...

concinciding of wheat growth in post-anthesis period by water deficiency can result in reduction of current photosynthesis. in this circumstance stem-stored carbohydrate from pre-anthesis period had an important role in supporting assimilates for growing grain. an experiment was conducted in 2007-8 in experimental farm of arsanjan islamic azad university, in order to investigation the quantity ...
The aim of this study was to assess the effects of strip cropping and different weed control methods on the yield and yield structure of dent maize, narrow-leafed lupin and spring oat. A split-plot design with four replications was conducted in 2008-2010. The following factors were analysed in the experiment: I. Cultivation method – sole cropping and strip cropping; II. Weed control method ...
