Some saline affected soils were selected at the locations Yosifya, Muwayliha, Imam, Eychreesh, Mahaweel, Ejbalah, Abe-Ghragg, Kifil, Elseneya and Eldagharaah. Using thermodynamic criteria to recalculate throught description quantitative concepts rather than analytical.The results indicate that the values ​​of SAR range from 0.96 - 26.80 (cmol Kg-¹)º<sup>·5</sup> of the studied sites and this ratio increased when taking into account free ions 3.52 - 32.7 (cmol Kg-¹)º<sup>·5</sup>. The ESP Calculated laboratory was (2.0 - 9.0 %) and all of these were less than ESP % according to laboratory salinity accounts, and generally show increase in the values ​​of the proportion of ESP with increased SAR according to the approved indicators.

Theseregions are located in provinces of Karbala, Babylon, Najaf, Diwaniyah, and Al-Muthana. Ten soil pedon were taken of soils that adjacent to the main Euphrates River, the Al-Hilaa, and the AL-Daghara Rivers in these provinces. Soil pedon of soils that on the banks or close to the main Euphrates River were taken of counties of Twarije, Kufa, Gamas, and Al-Samawa. In the same way, soil pedon of Missaib, Hashmiah, Diwaniyah, and Rumitha are adjacent to the Hilla River and soil pedon of Al-Daghara and Affak belongs to the area of Al-Daghara River. Results show a reduction in total boron concentration for all of the tested soil pedon directly related with the depth. Aggregate boron concentration values are the highest at the surface layer and reduce as going depth except for soils of Al-Samawa and Al-Rumitha. Total boron concentration values are fluctuated between 1.033 mg. kg<sup>-1</sup> and 14.658 mg. kg<sup>-1 in all of the studied soils. the results showed too the total boron values are not conducted with the tourmaline mineral percent in all sites</sup></h5> Raid Shaalan Jarallah, Bahaa Hussein Fadel Al-mayaly ##submission.copyrightStatement## http://qu.edu.iq/jouagr/index.php/QJAS/article/view/57 Sat, 01 Dec 2018 00:00:00 +0000 Improve the Growth and Yield of Figs by Foliar Nutrition at Post-Harvest http://qu.edu.iq/jouagr/index.php/QJAS/article/view/58 <h5 style="text-align: left;">A factorial experiment was carried out by spraying the fig (<em>Ficus carica</em> L.) trees cv.

Historically, the area had pioneering role in the human civilization for over 5000 years. The indigenous people of the area are called “Marsh Arabs” or “Ma’dan” who are the descendants of the Sumerians and Semitic people. The former Iraqi regime (Saddam Hussein) had violently led an aggressive campaign to drain the marshes in 1991. Only %7 of the total area survived this campaign, which caused a mass destruction of the ecosystem and dwellers’ displacement. In 2003, water started to flow back to the area. Yet, the reflooding did not restore the whole former area of the wetlands. Moreover, the new ecosystem influenced the diversity and characteristics of the co-existing species in the area. In 2016, due to the importance of the Mesopotamian Marshlands, the International Union for Conservation of Nature (IUCN) listed three marshes from the area as World Heritage Sites requiring conservation, namely: Hammar, Hwezeh and Central Marshes. The aim of this study is to re-evaluate the ecosystem of those three sites from a biological perspective by examining some challenges that should be dealt with to restore stability to this multi-thousand-year-old system</h5> Kadhim J.L.

They were collected starting of January till November 2016 with two age groups of chickens, (10-15 and 30-35) days old. Samples were examined with Modified Ziel -Neelsen stain to detect the positive samples by microscopic examination. After that, a nested-PCR technique was performed on 60 samples. Results of microscopic examination showed that total infection rate of <em>Cryptosporidium </em>was29.33% . The highest rates of infection were recorded in 10-15 days group and during spring season, infection rates reached were 35.71% and 34.28% respectively. The lowest rates were observed in 30-35 days group and during&nbsp; summer season were 23.75% and 20% respectively. No significant differences within percentage in both two age group or among percentage in seasonsat level (P &lt; 0.05) were recorded.&nbsp; According to Nested Polymerase Chain Reaction test, the results showed that overall percentage of infection is20%. The highest rate of observed infection is 23.33% in 10-15 days aged group, while the lowest rate of infection is (16.67 %) in the other age. No significant differences was observed between percentage in ages. On the other hand, result of&nbsp; comparing nested-PCR test with microscopic examination shows that there are no significant differences between the percentage of both tests.</h5> <h5 style="text-align: left;">In conclusion, cryptosporidiosis is widespread in broiler flocks in AL-Qadisiyah province, but there is no significant impact found concerning the relationship between infection rates and&nbsp; age of chickens or seasons of the year</h5> Tahseen A.
