Abstract: The thick, hard and water-impermeable seed coat cause physical dormancy and low germination rate in Albizia lebbeck (L.), to overcome this physical dormancy, seeds were pretreated with concentrated HCl and cold mist condition. Immersing seeds in concentrated HCl acid 37% for 30 and 45min effectively raised seed germination rate (35.56% and 46.67%) respectively as compared to control treatment (15.56%). Cold mist storage at 5◦C for 4 and 8 weeks also significantly increased germination percentage (51.11% and 68.89%) respectively. Furthermore, the combination of cold mist stratification for 8 weeks and immersion in HCl for 15min boost the germination rate to 75.56% an increase of 59.90% comparing to control treatment. For seedling parameters, all treatments have positive effects on the studied characters highest seedling height (37cm) and number of leaves per plant (18 leaves) where found in, 8 weeks cold mist condition, however, the combination of 15min acid scarification and 8 week cold mist stratification resulted in higher leaves area (207.52). Acid scarification and cold mist stratification both increased germinations and improved seedling features, but germination rates were highest and fastest when these treatments were applied together. The results suggest that to enhance seedling qualities, seed germination rate and speed, a combination of scarification and stratification should be used.

Abstract: This study included different soil locations around Mosul city representing non salt affected soils, and around Basrah city representing salt – affected soil. The aim of this study is to show the behavior of sodium due to first order and diffusion equations, using miscible displacement at different times (10, 20, 30, 60, 90, 120, 180, 360, 480, 600, 720 minute). The results indicate that the solubility and release of sodium decreases with time, but according to kinetic concept the cumulative of sodium solubility increased in the two type of soils study. However, salt affected soils showed more solubility and release of sodium than the non-salt affected soils. While the diffusion equation gave the best description of sodium solubility depending on the coefficient determination and standard error. Selectivity coefficient of Gapon due to the chemical concept KG, thermodynamic concept KG- and sposito concept KG= were also examend which showed that the values KG , KG- decreased with time , while KG= values increased over time.
Abstract: The study was conducted in Hatchery -private sector- in Qushtapa, Erbil, from 24-5-2016 to 14-6-2016. The hatched chicks were reared from(14/6/2016 to 26/7/2016) in one of the halls of Department of Animal Production in College of Agriculture/ Salahadding University-Erbil within total 63 days. This study was conducted to investigate the effect of thermal manipulation (TM) during different embryogenesis stages of broiler breeder eggs as at embryonic days (ED): T2 (1-5), T3 (19-21) and T1 was control (no TM) on hatching results and subsequent chick characteristics and broiler productive performance of thermally conditioned chicks (exposed to 38.0 ± 2 °C for 12 hours/day) at 21st day of age. One thousand eight hundred (1800) Ross-308 eggs from twenty seventh weeks old imported were used. Eggs were randomly divided into three treatments with four replicates per each treatment (600 eggs/ treatment). Two identical incubators were used. In the first incubator all eggs were incubated at 37.7 ºC and 60-65% relative humidity (RH). The eggs thermally treated were transferred into the second incubator and was kept at 38.2 ˚C and 60-65% RH. After four (4) hours (hrs.) of thermal treating, the eggs were returned to the first incubator, immediately. It was found that thermal manipulation did not affect the hatchability percentage of total and fertile set eggs, normal bird’s percentage, and chicks’ quality. Post-hatching, 270 day-old chicks were randomly assigned according to treatment groups within hatching process. Chicks were distributed into three treatments with three replicates-groups-, with thirty chicks per each replicate. All treatment groups were subjected to thermal conditioning of 38 ±2 °C for 12 hrs. /day for a week, from day 21stpost-hatching. After exposure body temperature of birds were measured. Live body weight, bodyweight gain, feed consumption, feed conversion ratio and mortality were recorded on weekly basis. Production index, dressing percentage and carcass cuts percentages were measured at 35 and 42 days of age of broiler chicks. The overall data showed the following results: 1- T2 showed significantly (p≤0.05) higher relative growth than control group and T3. 2- T3 and control group showed significantly higher feed conversion ratio than T2, so T2 had a better cumulative ratio. 3- T2 and T3 showed significantly (p≤0.05) lower rectal temperature than control group. 4- T2 had the higher production index than T3 and control group at marketing age of 35 days. 5- Control group showed significantly lowest cumulative mortality percentage than T2. In the embryogenesisdevelopment, the incubation temperature is increased by 0.5°C for 4 hrs. This thermal treatment of the body temperature leads to decrease of the chicks’ temperature at day 42, as compared with the control group. As a result it confirms the acquisition of thermo tolerance in thermally manipulated groups.
Abstract: A field experiment was carried out at two sites (Erbil and Mosul) in winter season 2017-2018, to study the effect of three different seed size (small, medium and large) of local broad bean planted in three sowing depths (5, 10 and 15 cm) using three levels of phosphate fertilizer (zero, 75 and 150 kg P2O5. ha-1) in yield and yield components.
