Implemented a field experiment is conducted in one of the farmers fieldsat
the bank of the Euphrates River in Ramadi - Anbar Province in the autumn
season 2010 to study the impact of two important factors on the
productivity of crop sunflower products Vlami, Group I, levels of
irrigation, the irrigation 100% (full irrigation), 75% and 50 % of ready
water, and Group II levels of plant density, distributed as follows (53 333
and 66 666 and 88 888) plants / ha, use a split plot design with random
sectors, where the occupied levels of irrigation main plots and plant density
secondary pieces. From levels of irrigation the first treatment of irrigation,
has given the best area of leaf is 6743 cm 2 / plant and the top holds the
seeds of the amount of 3.896 tonnes / ha and the top of each of the
consumption of water amounted to 399 mm / season, as well as the amount
of water given to where the 499 mm / season and the highest coefficient of
yield calculated from the basin of evaporation and the highest coefficient of
yield calculated from the equation of Kalat , while the third irrigation
treatment gives the highest efficiency in the use of water amounted to 1.868
kg / m 3, the less amount of water given 246 mm / season. The plant density
is low plant density 53 333 plants / ha increase in leaf area, while densities 66,666 and 88,888 plants / ha gave an increase in the sum of seeds 4.502 and
3.536 tons / ha, respectively, and water use efficiency is 1.824 and 1.386 kg /
m 3 respectively>

Experiment is conducted in the lath house in the the Department of
Horticulture , College of Agriculture, University of Baghdad. Seedlings of
Aloe vera plant are planted in plastic pots 28 cm in dimeter filled with
sandyloam soil. The research contains two separate experiments.
In the first experiment, nitrogen fertilizer is used as urea CO(NH2)2 46%
applied to the soil at a rate of:0,0.5,1.0,1.5 g. plant-1 or as afoliar spray at a
rate of :0,1,2,3 g . L-1.In the second experiment, cycocel is sprayed at the
following concentration :0,500,1000,1500 mg.L -1.The experimental results
show that nitrogen at the rate of N1.5g.plant-1 in the content of the leaves of
the aloin and barbolin , Alotic acid, anthrone, exceeds the fertilization
treatment N0.5g.plant-1 in the content of the leaves of Aloe- emodin,
exceeds the fertilization treatment N1.0 g.L-1 in the content of the leaves of
anthranol and cinnamic acid. The spray treatment of nitrogen at the rate of
N2g.L-1 increases the concentration of. aloin , Aloe-emodin , anthrone and
cinnamic acid. The spray treatment of cycocel at the rate of 1500 mg.L-1
for two spry increases the concentration of, cinnamic acid , aloin , barbolin ,
aloe- emodin and Alotic acid. The spray treatment of cycocel at the rate of
1500 mg.L-1 in four spry increases the concentration of cinnamic acid and
aloin . The spray treatment of cycocel at the rate of 1000 mg.L-1 for two
spry increases the concentration of anthranol and anthrone.

The study is conducted to determine the effects of Humic acid and planting
distances on growth and yield of Karkada ( Hibiscus sabdarifa L.) The
seeds are planted directly in field at 19-5-2010 . The experiment is designed
as a factorial experiment 322 by Randomized Completely Block Design .
The humic acid is sprayed on the leaves in rates of 0 ( control ) , 1.5 and 2
ml liter after one month from seedling emergence and in same rates
recurrent after one month . The seeds are planted at two distances 50 cm ,
70 cm. Results show that the humic acid has significantly effect on fruit
weight (5.53) gm and height plant(192.90)cm.
The planting distances have no significant effect on all plant traits . The
interaction between humic acid and planting distances have significant
effect on chlorophyll content(59.60) spad , number of Branches (37.60)
branch per plant , fruit weight (5.57)gm and plant height (132.0)cm.

A field experiment is carried out at Mishkab Rice Research Station , Al-
Najaf Governorate during summer season of 2008 to investigate the
response of rice to Herbicides ( Bispyrabic-Sodium , Propanil and
Oxadizon) on some characteristics , yield and its component of cultivar
Jasmine. The design used is RCBD with four replication. Bispyrabic-
Sodium causes a reduced number of weed at stages 30 , 60 and 90 day, from
plant sowing 16.7 , 75.7 and 80.3 plant.m-2 and also reduces the dry weight
of these plant by 83.6% compared with control treatment, therefore it gives
high value of plant height 91.6 cm , biological yield 1998.9 gm.m-2 , number
of tillering per square meter 420.6, number of grain per panicle 127.5
grains, also it gives highest paddy of rice 966.0 gm.m-2. It can be concluded
that the different of dosages among the herbicide gives the same result of
weed control and increasing paddy of rice according to weedy treatment.

The experiment is conducted to study the effect of gibberellin, cultar, and salinity levels and their interactions on flowering and fruiting characters of faba bean (Vicia faba L.) cv; local and luz De otono. Seeds are planted in metal canes at dimensions of 23 X 33 X 33 cm using silty-clay soil. The experiment runs during the period from 15-10-2006 until 17-4-2007. The two plant growth regulators used are; GA3 at 100, 200, or 400 mg/L and cultar at 250, 500 or 1000 mg/L in addition to control (plants sprayed with distilled water only). The salt levels are 0.02, 0.04 or 0.06 molar in addition to control treatment. Treatments are designed as a factorial experiment (7 x 4) in completely randomized design with three replicates. The flowering and fruiting parameters measured are; date to 50% flowering and podding, total flowers number, total pods number, percentage of dry matter of pods and seeds in addition to protein and carbohydrate percentage in seeds.
The results show that there are no significant effects of gibberellic acid treatments on the time to 50% flowering, or total number of flowers per plant. Cultar treatments causes an earliness of flowering and an increase in total number of flowers. Salinity treatments has a negative effect especially at the treatment of 0.06 molar of sodium chloride. Gibberellic acid treatments increase the time to reach 50% pods and decreased the total number of pods. Cultar treatments decrease the time to reach 50% pods and increase the total number of pods. Sodium chloride treatments have a reverse effect to that of the cultar. Dry matter percentage of pods and seeds decreased due to all treatments used. All treatments used have no significant effect in protein percentage in seeds of the local cultivar or carbohydrate percentage in seeds of luz De otono cultivar. Interaction between the two growth regulators and salinity levels has significant effect on most of the parameters determined especially the combination of the high concentration of gibberellic acid or cultar with the high level (0.06 molar) of sodium chloride.
