Field trial was conducted in Research Field equipped with rainfall transparent
shade, Biology Department, College of Science, Baghdad University during the
growing season of 2012 to test the potential of sorghum water extract in improving
yield and yield components of local cultivar of mung bean crop grown under
different moisture deficit stresses. The water stresses were applied by irrigated the
plots to field capacity and withheld the next irrigation until the soil water deficit
reaches 80, 50 and 30% of field capacity for control, mild water stress and higher
water stress, respectively. Foliar application of sorghum water extract at 0 ( control),
2.5 and 5% (W/V) was made at preflowering, flowering and fruiting stages. The
experiment was conducted in split plot design with four replications for each
treatment. The sorghum water extract rates were kept in the sub plot while moisture
deficits were assigned as main plot.
Results showed that drought stress significantly reduced the averages seed
yield , dry matter accumulation, number of pods per plant, number of seeds per pod
and plant height. Foliar applications of sorghum extracts significantly increased
seeds yield, dry weight biomass, number of seeds per pod and plant height. The
interaction of drought stress and sorghum water extract treatment significantly
affected seed yield , dry matter accumulation, number of pods per plant, total
chlorophyll content and plant height. Application of sorghum water extract under
severe moisture deficit stress (i.e., 70% field capacity) increased seed yield, dry
weight biomass and plant height , number of pods per plant, number of seeds per
pod by 37.8%, 48.9%,64.3%,8.7% and 5.1%, of control, respectively compared the
reduction achieved by the sever moisture deficit applied alone which was 58.50% ,
56.06% , 57.17% , 48.05% and 14.78 % of control for the aforementioned
parameters respectively.
Chlorophyll content was found to be increased by effected by application of
sorghum extracts at control moisture treatment. Proline content of leaves was
significantly increased by high drought stress when water extract applied alone.
However, such differences disappeared when sorghum extract was applied,
suggesting another mechanisms could be responsible for the stimulatory effect of
sorghum extract under drought stress.
Convolutional Neural Networks (CNN) have high performance in the fields of object recognition and classification. The strength of CNNs comes from the fact that they are able to extract information from raw-pixel content and learn features automatically. Feature extraction and classification algorithms can be either hand-crafted or Deep Learning (DL) based. DL detection approaches can be either two stages (region proposal approaches) detector or a single stage (non-region proposal approach) detector. Region proposal-based techniques include R-CNN, Fast RCNN, and Faster RCNN. Non-region proposal-based techniques include Single Shot Detector (SSD) and You Only Look Once (YOLO). We are going to compare the speed and accuracy of Faster RCNN,

Abstract
Endophytic fungi are gaining interest as sources of novel bioactive metabolites.
The study was carried out to screen and isolate endophytic fungus.An endophytic
fungus isolated from root of calyptous plant .The fungus was identified as
Stemphylium radicinum (Meier, Drechs and Eddy)based on morphological
characterization. Fungal secondary metabolites was carried out by ethyl acetate
solvent.The antibacterial activity was tested against five bacterial isolates.
Esherichia coli, Staphylococcus aureus, Proteus vulgaris, Klebsiella pneumonia and
Streptococcus pyogenes by using a disc diffusion technique. The inhibition zones
exhibited by Fungal secondary metabolites were ranged between 22.5-35.5 mm.

The present study was carried out to compare the physicochemical characteristics of eggs of guinea fowl, turkeys and domestic chickens outdoor reared in traditional farms in Baghdad, Iraq. A total of 166 fresh eggs; 32 eggs from guinea fowls (Numida meleagris), 44 eggs from turkeys (Meleagris gallopavo) and 90 eggs from domestic chickens; were collected. Egg weight, percentage of egg components, chemical composition (protein, lipids, and ash), and lipid profile were determined. Results revealed the significant differences in egg weight among studied birds. The average egg weights for guinea fowl, turkey, and indigenous chicken were 48.51 ± 0.72, 52.15 ± 0.74 and 61.24 ± 0.22 g, respectively. No significant differences were found in egg c
