Laboratory experiment was conducted using silty clay loam soil collected from Agriculture fields in Abu Ghraib to study the release of phosphorus from rock phosphate (10.22 P%) on  a soil treated with three types of organic fertilizers namely; peat moss , sheep manure  , poultry manure and  control treatment (soil only). Ten grams of air dried soil  mixed with 100 mg of ground rock phosphate  and  organic fertilizers added at 2.5% level (w:w) were  incubated at a laboratory temperature (298 K ) after adding  water  up  to two-thirds of the field capacity for 40, 90, 120, 150 and 180 days. Citric  acide  soluble  available phosphorous  was estimated after each incubation periods and kinetic equations used to test its release from treated samples. The additions of chicken manure was the highest in the  amount  of  dissolved phosphorus values followed by sheep manure, peat moss, rock phosphate and control treatment, reaching levels of citric  acide  extractable  phosphorus to  4.2 , 3.8, 3.3, 3.1 and 2.5 mg P kg-1 soil, respectively. The results also showed superiority of first  order equation in the description of phosphorus release from rock phosphate with  release  rate   coefficient  of 3.801 , 3.865 , 4.328 and 4.366 mg P kg -1 soil h-1 for the treatments: soil and rock phosphate only , peat moss, sheep waste and chicken manure, respectively.

A field experiment was conducted at the experimental farm, College of Agriculture, Abu-Ghraib, Baghdad, Iraq during the period from mid. of March 2012 to mid. of July 2014 to investigate the effects of plant growth regulators and foliar application stages on ovules abortion, seed set and its germination of two alfalfa cultivars. Layout of the experiment was R.C.B.D. arranged in split-split plot with three replications. Cultivars (local and hamedan) were assigned as a main plot and foliar application stages (vegetative growth, flower buds emergence, 50% flowering and 80% flowering) were assigned as sub-plots, while growth regulators (Alar, Ethephon, Naphthalene acetic acid(NAA) and control treatment) were assigned in the sub-sub-plots. Result showed that there were no significant differences between cultivars in all traits. Foliar application of NAA increased No. of ovules per floret (9.11) compare with other treatments, but it was not significantly different compare with Alar. In 1st and 2nd seed crop, plants sprayed with Alar at flower buds emergence stage gave highest seed set (5.17, 6.93) respectively. Percentage of ovules abortion significantly influenced by growth regulaters, folair application stages and their interaction. Since, foliar application of Alar at beginning of flower buds emergence reduce % of ovules abortion (30.89). In general, plants sprayed at vegetation growth stage increased % of seed germination. It was clear from this study that more than 40% of ovules were aborted, this may be one of the reasons for reduction of seed yield in alfalfa, therefore, we recommended to do more researches in this field in order to know the causes of ovules abortion.

Abstract The experiment was carried out in the greenhouse of the Agricultural Research and Experiment Station - Kirkuk University - College of Agriculture for the agricultural season 2020-2021. The experiment was started on 20-11-2020. Carnations were taken from the mothers before the start of the experiment and planted in culture dishes to complete the rooting process. Carnations were planted on terraces with a length of (20 m) and width (75 cm), and the distance between one line and another (30 cm) and between one plant another (30 cm) as well. Artificial lighting (white LED light factor, 40 watts) was used for four hours in addition to the natural light which started half hour before sunset. The intensity of lighting was measured by a light meter (Lux 6612). As for the mulching factor, the industrial mulching was used with white polyethylene and the natural mulching with shredded yellow corn residue with a thickness of 2.5 cm, in addition to the control treatment. The experiment was carried out in a split-plot system in a randomized complete block design (RCBD) and the treatment of illumination was placed in the main plots, while mulching was placed in the secondary plots, and the results were tested according to Duncan’s multiple range test at a probability level of 5%. The following characteristics were studied: plant height (cm), plant total chlorophyll content (CCI), number of days required for flowering (day), number of flower/m2, and flower stem length (cm). The results showed the superiority of lighting and mulching treatment in all vegetative and flowering traits under study.

For Iraqi EFL learners who are studying English pronunciation in a traditional instruction method often requires more effort and hard work. Thus, using new methods of teaching such as the flipped classroom model (FCM) is necessary to facilitate learning and improve performance. Hence, this study reports on explanatory research that investigates the effect of using the FCM in the teaching of English pronunciation for Iraqi EFL learners at the university level. The study implemented mixed research methods for data collection in a quasi-experimental analysis. Therefore, two tests were conducted on the assigned groups to measure the effect of the FCM before and after the intervention. Besides, a questionnaire and interviews were used on the experiment group students to collect data about their perceptions of the FCM. The study length (lasted)  was 15 weeks and is comprised of 60 students from the department of English, College of Arts at the University of Anbar. The students were divided into two groups, experimental, and control with 30 students in each group. The findings revealed that there was a significant statistical difference between the two groups in favour of the experimental group with better performance, indicating that the FCM has considerably assisted the Iraqi EFL learners to improve their English pronunciation. Moreover, the students expressed their positive feedback and satisfaction on the use of the FCM in their responses to the questionnaire and the interviews. As such, the current study recommends further research to study the effect of applying the FCM in areas and disciplines other than language learning.
