Field and laboratory experiments were performed to evaluate the allelopathic
potential of sorghum residues alone or in combination with reduced rate of trifluralin
herbicide on weeds in mung bean field. The field experiment was conducted during
2014 season at the Research Farm of Biology Department, College of Science,
Baghdad University by using randomized complete Block design (RCBD) to test the
effect of sorghum residues at rates of 5 and 10 t ha-1 alone or in combination with
reduced doses of trifluralin (30 and 60% of recommended dose) on weeds and mung
bean crop. Weedy check and label rate of trifluralin (2.4 Lha-1) were also included
for comparison. Each treatment was replicated four times. Total phenolics in field
soil amended with sorghum residues at 10 t ha-1 was determined in at 0, 14, 28 and
42 days of sorghum residues decomposition. Also bioassay experiment was
conducted to test the allelopathic effect of sorghum residues at 10 t ha-1
incorporated into the field soil on seedling emergence and growth of Portulaca
oleracea weed during the above mentioned decomposition periods. Results showed
that incorporation of sorghum residues at 5 t ha-1 reduced weed density by16.9 and
18.8% of control after 30 and 60 days from sowing, respectively. The reduction was
increased when sorghum residues were incorporated at 10 t ha-1 and reached to 30
and 30.5% of the control after 30and 60 days from sowing, respectively. However,
the suppression of weed population and dry weight biomass was further improved
when the plots were treated with 30 and 60% of label rate of trifluralin and sorghum
residues at 5and 10 t ha-1. The highest suppression of weed population and dry
biomass was achieved by application of reduced rate of trifluralin (60%) to plots
amended with sorghums residues at 10 t ha-1. Integration of reduced herbicide and
sorghum residues at 5and 10 t ha-1 resulted in more weed suppression than sole
application of the respected sorghum residues. The results also revealed that weed
suppression was directly translated into yield of mung bean. Application of
trifluralin herbicide at 60% of label rate in plots amended with sorghum residues at
10 t ha-1 recorded the highest biological and grain yield, number of pods per plants
and weight of 100 seeds. Chemical analysis indicated that total phenolics started to
increase at14 and 28 days of decomposition and decline thereafter until vanished 6
weeks of decomposition. Biological activity test of field soil revealed that
suppression of Portulaca oleracea weed was highly correlated with total phenolics
(R2 = 0.95for seedling emergence and 0.87 for dry biomass) of soil suggesting that
high weed suppression was mainly due to high activity of phenolics.
The movement and broadening of foreign and European words into Persian is a topic within historical linguistics. Such changes are semantic, phonological
Since many of these European loanwords into Persian took a remarkable space within Persian dictionaries, and became an indispensible part of the language, a study of the original languages of these loanwords may identify the enormous effect of those languages upon Persian, being a receptor language, and may refer to the liveliness.
Among the important factors which helped the movement of various loanwords into Persian are:
- Geographical: this is seen via contact between Persian people and those neighboring people, specifically those speaking Ara
Hate speech (henceforth HS) has recently spread and become an important issue. This type of speech in children's writings has a particular formulation and specific objectives that the authors intend to convey. Thus, the study aims at examining qualitatively and quantitatively the classism HS and its pragmatic functions via identifying the speech acts used to express classism HS, the implicature instigated as well as impoliteness. Since pragmatics is the study of language in context, which is greatly related to the situations and speaker’s intention, this study depends on pragmatic theoriespeech acts, impoliteness and conversational implicature) to analyze the data which are taken from Katherine Mansfield's short story (The D

In this research the Empirical Bayes method is used to Estimate the affiliation parameter in the clinical trials and then we compare this with the Moment Estimates for this parameter using Monte Carlo stimulation , we assumed that the distribution of the observation is binomial distribution while the distribution with the unknown random parameters is beta distribution ,finally we conclude that the Empirical bayes method for the random affiliation parameter is efficient using Mean Squares Error (MSE) and for different Sample size .
The Purpose of this study is mainly to improve the competitive position of products economic units using technique target cost and method reverse engineering and through the application of technique and style on one of the public sector companies (general company for vegetable oils) which are important in the detection of prices accepted in the market for items similar products and processing the problem of high cost which attract managerial and technical leadership to the weakness that need to be improved through the introduction of new innovative solutions which make appropriate change to satisfy the needs of consumers in a cheaper way to affect the decisions of private customer to buy , especially of purchase private economic units to

His book Albidaya Walnihaya is considered among the important historical sources. This book's study of the subject of commercial dealing methods clarifies that the commercial dealing methods dealt by the people throughout the successive historical eras were multiple, most prominent of which was money (whether Dirhams, Dinars, measures (mikyals), weights (like Sa') in addition to other means like usury. But here we notice that Iben Katheer stressed that usury must be prohibited because it is religiously forbidden and cited many Quranic verses and Prophetic sayings w

The dental caries and gingivitis/periodontitis are widespread chronic diseases in diabetes. The aim of the present study was determined the salivary matrix metalloproteinase (MMP-8), Secretory Leukocyte Peptidase Inhibitor (SLPI) and oral health status among uncontrolled diabetic group in comparison with healthy control group. Materials and Methods: The total sample composed of 90 adults aged (18-35) years. Divided into 60 uncontrolled diabetic patients (HbA1c >7%) and 30 healthy control group.
