2024-02-06T11:26:07+00:00

This study was carried out in the vineyard of the Department of Horticulture and Landscape Design, College of Agriculture and Forestry at the University of Mosul, Mosul City, Iraq. During the growing season 2022 to study the effect of foliar fertilization of Nauta fertilizer containing amino acids and seaweed extracts and foliar spraying with gibberellic acid (GA₃) on three varieties of table grapes, Halawani, Kamali and Khalili and the extent of their impact on vegetative growth. Foliar spraying of organic fertilizer NAUTA with 0, 250 and 500 mg l^-1 and spraying with a solution of gibberellic acid with 0, 50 and 100 mg l^-1. The most important results obtained that vegetative growth differed according to the varieties under this study, Foliar application of NAUTA organic fertilizer, especially at a concentration of 250 mg l^-1, led to a significant increase in the rate of height and diameter of the main stem, the leaf area , the leaf area of the seedling, the concentration of chlorophyll in the leaves. Spraying with 100mg l^-1of gibberellic acid, led to a significant increase in the average height and diameter of the main stem, leaf area, the leaf area of the seedling, protein. The results of the triple interaction between the levels of the studied factors showed a significant effect on vegetative growth.

The effect of Medical City waste on the quality of plankton diatoms in Tigris River at central Baghdad

A quarterly qualitative study of the plankton diatoms within the waters of the Tigris River was conducted, starting from September 2022 until May 2023, to find out the effect of the liquid medical city waste released to the Tigris River on the quality of plankton diatoms within Tigris River for three sites confined between Al-Sarafiya Bridge in the north and Medical City Bridge, the site of Al-Khader Elias in the south, and the middle site affected by sewage waste for the Medical City Hospital Compound, with the study of some physical and chemical variables of the river water. The study was able to record 94 species of diatoms belong to the 26 genera in which pennate diatoms prevailed 74 species belonging to 21 genera while the centric diatoms recorded a smaller number of 20 species belonging to 5 genera. The study also showed the effect of sewage water for hospitals Medical City on the quality of diatoms, which it was few throughout the study period and the waste loaded with organic matter and antibiotics with high concentrations caused a decrease in the number of diatoms species throughout the study period within the site directly affected by waste.

Senna seed germination and seedling growth stimulation by the use of gamma rays and electric shock

2024-02-06T11:32:30+00:00

The experiment, which examined the effects of electric shock and irradiation on indicators of senna seed germination and seedling growth, was conducted in labs and fields owned by the Medicinal and Aromatic Plants Research Unit of the College of Agricultural Engineering Sciences at the University of Baghdad in 2019. The experiment used an RCBD design with three replications and included six treatments (T1), seed electric shock with 4 and 6 Ampere (T2, T3), and seed irradiation with 10, 20, and 30 Gry (T4, T5, and T6). The findings revealed that the T4 and T3 treatments had the highest germination rates, wet weights of seedlings, and dry weights of roots, respectively, of 33.3, 32%, 0.225, 0.220 g, and 0.178, 0.167 g, while T2 and T4 had the highest dry weights of seedlings (0.0450, 0.0420 g, respectively). The highest levels of chlorophyll (SPAD) were found in the T2 and T3 treatments (44.17 and 43.7, respectively), indicating the importance of gamma rays and electric shock in promoting seed germination and seedling growth.

Study about the types of blood parasites that infect Iraqi camels and their infection rate in AL-Furat Al-Awsat Governorates

2024-04-13T09:32:31+00:00

Field epidemiological survey was conducted to find out the types and percentage of blood parasites infecting Iraqi camels in the governorates of AL-Furat AL-Awsat governorates (Karbala, AL-Najaf, AL-Qadisiyah, Babel and AL-Muthanna). A total of 125 blood samples for both sexes were collected randomly from camels that were coming for treatment in clinics veterinary services for the aforementioned governorates for a period time from 1/4/2020 to 1/4/2021, where the ages of the camels were (less than one year and 20 years), some of these camels were in a very good health condition ( un infected camels) about (27) animals; while the other not ( infected camels) about (98) animals .(2) mm of blood volume was collected from the jugular vein and placed in containers containing an anticoagulant (ethylene diamine tetra acetic acid EDTA). We see the highest number and percentage of infection were, respectively, of Anaplasma parasite in (37) with a rate of (29.6%), then the Babesia parasite with a number of (25) by (20%), then the Theileria parasite with a number of (19) by (15.2%); the lowest percentage was infection with a blood parasite by trypanosomes with a number of (17) by (13.6%); Thus, the types of blood parasites recorded a significant statistical difference at the level (P ≥ 0.05). The results of the clinical examination showed that there was a statistically significant difference (P ≥ 0.05) between the groups of uninfected and infected camels in sex and age. The infection of females was much higher than that of males at a rate of (52%) in females, while (26.4%) in males. Upon statistical analysis of this result, it was found that there was a significant statistical difference at the level of (P ≥ 0.05) between males and females. As for the results of examining blood slides for infection with parasites and their relationship with the age of the animal and for all types of parasites, it showed that the highest number and percentage of infection for all types of parasites was at young ages (5 years - 10 years) and the lowest percentage of infection also for all types of parasites was at ages (11 years - 15 years) this result not record statistically significant difference (P ≤ 0.05). Our study recommended that making periodic teams to treat flies and ticks and to give medicines that treat all parasites; carrying out extensive studies on camel blood diseases because of their impact on camel productivity then affecting the economy of the country; carrying out preventive programs by mobile teams to give vaccines, vitamins and all preventive medicines; carrying out research studies to find out whether camel blood parasites are transmitted to humans or not conducting a study to find out if there are negative effects of camels infected with parasites on people who are in direct contact with them.
