in order to study of nitrogen application time and seed inoculation with plant growth promotingrhizobacteria on yield, fertilizer use efficiency and grain filling rate of sunflower, a factorial experimentwas conducted based on randomized complete block design with three replications in research farm ofislamic azad university, ardabil branch in 2011. the first factor was time of nitrogen applica...

in order to investigate the possibility of reducing herbicide usage in combination with plant density and planting pattern, a field experiment was designed in chenaran, khorasan razavi, on 2010. the experiment was split plot treatments based on rcbd with three replications in factorial arragement. the treatments included of 3 level of plant density (100000, 120000 and 140000 plants ha-1) and 2 ...

The present study was carried out to determine the relationship between physiological characteristics with grain yield (GY) in barley cultivars. In this study, significant differences were found varieties (p ≤ 0.01 or p 0.05) all characteristics, except GS77 (late milk formation) period Normalized Difference Vegetation Index (NDVI). While Erciyes, Çatalhüyük, Asutay and Aydanhanım cultivars hig...

Tropical maize is an alternative energy crop being considered as a feedstock for bioethanol production in the North Central and Midwest United States. Tropical maize is advantageous because it produces large amounts of soluble sugars in its stalks, creates a large amount of biomass, and requires lower inputs (e.g. nitrogen) than grain corn. Soluble sugars, including sucrose, glucose and fructos...

An ultrasonic technique was used to study the changes of the rheological properties of dough during fermentation at 37C and compared with the ertensional properties of fermented dough obtained from tensile tests carried out in a Universal Testing Machine. The velocity and attenuation of a longitudinal wave (P-wave) propagated through the dough samples were measured and analyzed to obtain the vi...

Adolescence marks the period in which a young person attains adult stature and sexual maturity, and begins abstract thinking. These changes present both the adolescent and his parents with new challenges, new problems, and new circumstances that have not been encountered in any previous childhood developmental stage. The primary goal of parenting during this stage is to have the child develop i...

We present a gauge-invariant formalism to study the evolution of the curvature and entropy perturbations in the case in which spatial and time variations of the inflaton decay rate into ordinary matter are present. During the reheating stage after inflation curvature perturbations can vary with time on super-horizon scales sourced by a a gauge-invariant inflaton decay rate perturbation. We show...

If recognition of a polymorphemic word always takes place via its decomposition into stem and affix, then the higher the frequency of its stem (i.e., base frequency) the easier the lexical decision response should be when frequency of the word itself (i.e., surface frequency) is controlled. Past experiments have demonstrated such a base frequency effect, but not under all circumstances. Thus, a...

"Elasticity" in bakery is a sensory perception that is felt when the dough is rapidly stretched and released. Elasticity is good when the dough contracts rapidly to approximately its original shape. In another test the baker tries to stretch the dough into a thin membrane (Fig. 82). The formation of membranes with no fissures is attributed to good gluten quality 14 The Role of Gluten Elasticity...

Articulating a clear and concise research question is fundamental to conducting a robust and useful research study. Although “getting stuck into” the data collection is the exciting part of research, this preparation stage is crucial. Clear and concise research questions are needed for a number of reasons. Initially, they are needed to enable you to search the literature effectively. They will ...
