this experiment was conducted in 2012 at the research field of alborz research station, research institute of forests and rangelands, karaj, iran, to study the effect of chemical and biological fertilizers on sage (salvia officinalis l.) and replacing biofertilizers instead of high doses of chemical fertilizers. the experiment was conducted in factorial in the form of a randomized complete bloc...
In this study, factor analysis was conducted to determine the factors which contributed to the variation of quantitative traits and path analysis was performed to find the direct and indirect effects of yield components on grain yield in bread wheat. A doubled haploid population of 157 lines of wheat (Triticum aestivum L.) was evaluated for agronomic and morphological traits, using a randomiz...
Understanding the soil-plant relationship is important to determine critical limits of soil properties that influence crop growth and yield. The objectives were quantify compaction levels on physical yield in a clayey Oxisol. An experiment was performed having main plots, (NT: no-tillage during six years, NTC: NT + four passes 10 Mg machine agricultural year 2003/2004, Chisel: chiseling harrowi...
two different propagation procedures including aeroponics and soil systems were compared for the minitubers production in potato. the minitubers were evaluated for several quality characters. the plant materials were from three cultivars, agria, marfona and savalan. the plantlets were grown in aeroponics and soil production systems at a plant density of 100 plants per m-2 and stem length, root ...
rhizomania (root madness) is caused by beet necrotic yellow vein virus (bnyvv). this disease was first reported fromitalyin 1959 and fromfars,iranin 1996. during the recent years, it has been increasingly developing across the country so that most beet production areas such as khorasan, fars, west azarbaijan,isfahanandkermanshahare now more or less affected by the disease. typically, the taproo...
چکیده یکی از مهمترین دغدغه های بزرگ جوامع بشری، از دیر باز تا کنون که ذهن پژوهشگران و متخصصان بهداشت روانی و اجتماعی و دولتها رابه خود مشغول داشته، مسأله ی بزهکاری می باشد. شناخت کامل پدیده ی بزهکاری و بزهکار، علل وعوامل سقوط یک انسان، چگونگی درمان وی و درنهایت پیشگیری ازبزهکاری ودریک کلام سالم سازی یک جامعه، رسالت عظیم، انسانی ومقدسی می باشد که با بررسی شخصیت مجرم یعنی[ انسانی که تحت شرای...
Due to the increasing need of the country to imported edible oil and rapeseed importance among oilseeds, efforts to increase its grain yield and oil content are of high importance. Therefore, recognizing the traits that increase grain yield of rapeseed has an important role in the success of breeding programs. Thus, sixteen rapeseed genotypes were evaluated in a randomized complete block design...
Considering the effect of salinity stress on the quantitative and qualitative traits of sugar beet genotypes, it seems necessary to study the response of genotypes obtained from breeding programs to salinity stress. For this purpose, 17 full-sib genotypes (derived from sibling crossing) with 7 different tolerant control under two salinity stress (electrical conductivity 17.36 dsm) and without s...
Genetic diversity is the base of plant breeding. Hence, 33 M7 soybean mutant lines, which were evolved by γ ray from cultivar L17 irradiated with doses of 150, 200 and 250 Gray (absorbed dose), with L17 cultivar and two commercial cultivars (Clark and Williams) were evaluated in view of some morphological traits (number of leaves/plant, pods/plant, seeds/pod, seeds/plant, 100-seed weight, dry w...
In order to study the effects of seed pre-treatment with potassium nitrate (KNO3), gibberellic acid (GA3) and hydro-priming on growth and yield of two sugarbeet cultivars, an experiment was conducted at Miyandoab Agricultural and Natural Resources Research Station in 2009 growing season. The experimental design was a factorial based on randomized complete blocks design with three replications. ...
