the time of duration of plant developmental stages could have an effect on crop yield and adaptation in a specific environment. the aim of this study was to evaluate the phenological behavior in a wide range of wheat cultivars and their relation with adaptation and potential of crop production in a specific climate (semi-arid and cold). by using a simple lattice design with three replications i...

in order to evaluation of plant densities and row spacing effects on growth and yield of wheat, an experiment was conducted by using four plant densities (125, 250, 375 and 500 plants per m2),two row spacing (12.5 and 25 cm), in a randomized complete block design with three replicates in anbare-ololum reign in rainfed and saline conditions during 2008-2009. results showed that leaf area index (...

ABSTRACT Perennial ryegrass (Lolium perenne) was inoculated with urediniospores of Puccinia graminis subsp. graminicola at four stages of reproductive tiller development. All developmental stages, from expansion of the penultimate leaf through anthesis, were equally susceptible to infection measured as number of pustules per total inoculated plant area. However, within each stage from boot thro...

Phosphorous (P) is one of the most critical macronutrient elements for plant growth, yield and quality. However, natural P sources are finite an improved recycling necessary. Therefore, we investigated effect bone char (BC) plus (BCplus) as products alternative fertilizers, on abundance microorganisms, which catalyze major steps in turnover a field experiment Central Germany. The effects were c...

to investigate the effect of nitrogen rate and split form of application on dry matter remobilization among different rice cultivars, a field experiment was carried out in the rice research institute of iran (amol) – during 2005. a split–split experiment on the basis of a randomized complete block design with 3 replications involving 3 factors was employed in which fertilizer rates (100, 150 an...

in order to study the effect of deficit irrigation at reproductive growth stages on growth and grain yield of four sunflower cultivars namely: azargol, allstare, alison and euroflor, an experiment was conducted during the 2007 growing season at the experimental field of the agricultural faculty of bu-ali sina university. the experimental design was a split plot one, based upon a randomized comp...

In plants gibberellins (GAs) are responsible for triggering stem or internodal elongation. To comprehend the molecular basis of internodal elongation in rice, a proteomics approach using differentially displayed proteins on two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) was carried out to identify the proteins expressed during the GA controlled leaf-sheath elongation response. Ou...

in order to investigate the effect of insufficient irrigation on remobilization percent and plant dry mater in three spring safflower (cartamus tinctorius l.) genotypes, a field experiment was conducted at research farm, faculty of agriculture, the university of birjand, iran, during 2008-2009, as a spilt plot arrangement based on randomized complete block design with four replications. irrigat...

to study the effect of urea application in safflower (carthamus tinctorius) and determination of effective traits on its yield, a factorial experiment based on randomized complete block design in three replications was conducted in tabriz, iran, during 2012. studied factors were urea rate levels as 100, 150 and 200 kg/ha and urea application times 100% in sowing time, 50% sowing time + 50% stem...
