Abstract: The current study aimed to evaluate the effects of potassium iodide in-ovo injection on thyroid gland activity and some hematological and biochemical indices of broiler chicks. A total of four hundred seventy-seven fertilized broiler eggs (Ross 308) were randomly distributed into 3 groups (159 eggs/group), with 3 replicates (53 eggs/replicate). Eggs of 1st group were considered as a negative control (not injected), the 2nd group eggs were injected with 0.2 mL deionized water (positive control), whereas the 3rd group eggs were injected into the allantois sac, with 2 mg potassium iodide/ egg in 0.2 mL volume, on the 10th day of incubation. At the hatch day, hatchability%, embryonic mortality%, chicks weight were measured, and the hematological and biochemical tests were conducted. The weight of the hatched chicks from injected eggs with potassium iodide was significantly lower than that in negative control group (P≤0.05), moreover, a significant increase was recorded for hemoglobin, packed cell volume%, lymphocytes%, and thyroxin concentration as compared with the control group, meanwhile a significant decrease was recorded for the heterophils%, H/L ratio, cholesterol, triglycerides and triiodothyronine concentration as compared with the control group (P≤0.05). In conclusion, potassium iodide has an important impact on thyroid activity and reduce stress on the incubated eggs, as well as on some hematological indices of hatched chicks.

Abstract: The experiment was carried out during the winter agricultural season 2018-2019 in Nineveh Governorate at two location (Hamdaniya district 25-30 km east of Mosul  and Talkif district 25-30 km north of Mosul), the experiment include two factors, tillage systems (conservation  and  conventional tillage) and seeding rates (80 , 100 and 120 kg.ha-1), the seeds were planted at 11/1/2019 and 12/1/2019 for the two locations respectively. The variety   Adana  registered certified by Ministry of Agriculture was used. The experiment was applied as factorial experiment  using split plots system by R.C.B.D with three replications. The main plots contained the two tillage systems levels , and  the sub plots contained seeding rates levels , the experimental unit area was 20 m2,  The results showed no significant differences between tillage system in number-of narrow and broad leaves weeds and their weight for two location but the conservation  tillage was  surpassed conventional for grain yield  by 78.57 and 119.52 gm.m-2 in Hamdaniya and Talkef  location respectively, non-significant differences between the seeding rates in no-of narrow and broad  leaves weeds for two location , but seeding rate 120 kg.ha-1 surpassed 80 and 100 kg.ha-1 for grain yield 281.89 and 360.01 gm .m2 in Hamdaniya and Talkef location respectively. Non–significant differences between the seeding rates with conservation or conventional tillage in narrow leaves weeds for two location but lower number-of broad leaves weeds in seeding rate 120 kg.m-2 with conservation agriculture for two location. The best grains yield  obtain with seeding rates 120 kg.h-1 and conservation tillage by  314.62 and 405.02 gm.m-2 in Hamdaniya and Talkef locations respectively.

Abstract: A field experiment was conducted in one of the fields in Nineveh Governorate, in soil texture was clay silty loam, under the axial sprinkler system, where the research included studying the effect of (two levels of soil moisture (13-15%), (17-19%), two depth of tillage (12-14 cm) and (15-17 cm), and three types of chisel plow-share (conventional share, the spearhead and the severed share)), on the following field indicators (draft force, soil adhesion force, the tillage appearance through (number of clods with a diameter larger than 7.5 cm) and the vertical deviation ratio to tillage depth). This experiment was implemented with split-split plot under randomized complete block design (RCBD) with three replicates. The results showed that the lowest draft force, adhesion strength, number of clods, and the lowest vertical deviation ratio to tillage depth were recorded in the soil moisture content (13-15%), the depth (12-14) cm recorded the lowest draft force, adhesion strength and a number of clods, while it outperformed depth (15-17) cm in obtaining the lowest ratio of vertical deviation, as the severed share outperformed in obtaining the lowest draft force, adhesion strength and a number of clods, while the spearhead share outperformed in obtaining the lowest ratio of vertical deviation, achieved interaction between the soil moisture content (13-15%) and the depth (12-14) cm, the lowest draft force, adhesion strength and a number of clods, while the interaction between the soil moisture content (13-15%) and depth (15-17) cm achieved the lowest  ratio of vertical deviation.

Abstract:  This experiment was carried out in the Green net house at the College of Agriculture and Forestry for the period from April to September 2019, with the aim of assessing the response of three cultivars of Gladiolus X hortulanus L. for treatment with (SA)  at a concentrations of zero and 250 mg.l-1 as well as treatment with (CaCl2) concentrations are zero, 500 and 1000 mg.l-1 sprayed on the vegetative growth twice. The results indicated the following: The red cultivar recorded the largest height, the number of leaves, shortest the period from planting to the inflorescence bud initiation and longest vase life, While the white cultivar recorded the largest value of spike length. The plants sprayed with SA had a significant effect in recording the largest values of all studied traits except for the duration from planting to the inflorescence bud initiation, which decreased significantly. The treatment with CaCl2 with both concentrations resulted in a significant increase in the number of leaves and the spike length, The treatment with CaCl2 at 1000 mg.l-1 gave the largest values for the plant height and  the vase life. showed that red and white cultivars produced flower that fall within a special grade when they were sprayed with SA or did not interact with spraying with CaCl2 at 1000 mg.l-1, while the violet cultivar ended their flowering 5 days when they were sprayed with SA interact with CaCl2 at 1000 mg.l-l.

Abstract: The work carried out on a privet local farm extended to eight weeks in Mosul city Iraq. Sixty local male rabbits, six to seven weeks aged, with an average initial bodyweight of 552 ±15gm. Randomly divided into 4 treatments and 3 replications (5 rabbits each). Soybean meal replaced by black seeds (Nigella sativa L.) meals at levels 0, 33, 66, and 100% respectively in the diets as a crud protein source. The diets were nearly equal in the level of energy digests and the percentage of crude protein. Treatment 4 (100%) showed a significant effect (p≤ 0.05) in increasing daily weight gain, daily consumption, total weight gain, hot and cold carcass weight. A higher mortality percentage was in T1 (6.67). While our other results did not show any significant differences in all other studied traits. T4 showed the highest profit in weight gain (Kg) / Iraqi Dinar) then T3, T2 and T1 respectively.

In grain yield trait, the interaction between the planting  method (ZT 17+P) with all sowing  rates and the planting method (ZT 34+P) with (120 and 100 kg. ha-1) sowing rates  achieved the highest significant value in grain yield, while the interaction between CT  with (80 kg. ha-1) sowing rate has the lowest significant value in grain yield.

Abstract: The current work aims to study three seed cultivars of rapeseed (Brassica napus), as well as trying to provide a phytochemical insight of different rapeseed cultivars to be potentially cultivated as natural alternative hydrocarbon sources to petroleum hydrocarbons. The three seed cultivars, namely Heros, Sultan and Reandy were purchased from Britain, India and Sweden, respectively. After being cultivated, the seeds were collected, dried, and crushed. Oils from the crushed seeds were extracted with n-hexane as a solvent, and the attained oils were analyzed by GC-MS. The results showed that the tested oil seeds exhibited valuable phytochemical constituents, possessing increased percentages of long chain hydrocarbons. The 2,4-Decadinal (E,E)-(CAS) was the superior phytochemical compounds in Heros (18.73%) and sultan  (29.35%) seed oils, However, it was the second prevalent compound in Reandy seed oils. Also, percentage of the hydrocarbons content of the reandy seed genotype was (39.91%) higher than that of the Sultan (17.78%) seed oils. The most prevalent fatty acids were shown to be 9-Octadecenoic acid all the three tested gen verities. Based on the obtained data, Good hydrocarb plant yields can be offered by Heros and reandy cultivars. Also as a seed oil, could be considered as efficient plant oil for the industrial utilization as non-edible oils or in the biodiesel production as a low emission renewable energy.
