This study was conducted at a research station affiliated with the Department of Horticulture and Landscape Engineering, College of Agricultural Engineering Sciences, University of Baghdad, during the spring season of 2024. The study aimed to investigate the effect of inocul mycorrhiza fungi, seaweed extract, and the amino acid arginine, along with their interactions, on the chemical and root characteristics of sweet corn plants. The experiment involved three factors: inoculating sweet corn seeds with mycorrhizal fungi at two levels (M0, M1), foliar spraying with seaweed extract at three concentrations (0, 1, 2 mL L⁻¹), and foliar spraying with arginine at three concentrations (0, 125, 250 mg L⁻¹). The study was conducted using a randomized complete block design (RCBD) with a split-plot arrangement. Results showed that the three-way interaction (M1S2G2) showed significant superiority in the studied traits, including Percentage of Nitrogen, and potassium with the value 2.80% N , 0.416% P and 2.17%K respectively, root length (30.67 cm), number of root branches ( 40,475 branches per plant), and root dry weight (36.00 g).
This study was aimed to investigats effect of foliar application with moringa extract , yeast, and adding humic acid on antioxidants content of the marigold plant flower . The study was conducted at Research Station A- College of Agricultural Engineering Sciences - University of Baghdad, during the autumn seasons of 2021-2022 and 2022-2023, The experiment was carried out as Randomized Complete Block Design (RCBD) with three replicates. Three factors were included in the study: foliar application of moringa leaf extract at concentrations 4,6,8% (M1, M2,M3), in addition to the control treatment M0, as well as yeast suspension at concentrations of 5 and 10 g L-1 (Y1 and Y2), in addition to the control treatment without spraying (Y0). Furthermore, humic acid was applied at two concentrations of 0, and 5 ml L-1 (H0 and H1) The results showed a significant superiority of the treatment M3Y2H1 in Lutin, Rutin, Quercitrin ,Kaempferol and Isoquercitrin, at (11.343, 99.23, 66.81, 64.39, and 38.77) µg g-1, respectively, compared to the control treatment (7.043, 95.16, 61.82, 59.46, and 33.16) µg g-1, respectively. For the second season the treatment M3Y2H1 recorded (9.706, 88.22, 62.83, 60.28, and 34.76) µg g-1, respectively, compared to the control treatment, (4.525, 82.18, 58.15, 55.11, and 30.11) µg g-1, respectively.
The aims of this study to validate a specific primer to confirmatory identification of three Raillietina species in naturally infected feral pigeons (Columba livia). Initially intestinal examinations were conducted on 55 birds, revealing the presence of Davaineidae through morphological identification. The primers previously designed targeting ITS2 region. The results showed that 35 (63.6%) of the examined birds were infected with cestoda. Molecularly, DNA was extracted from 60 cestode samples. The primers successfully amplified specific species without cross-amplifying of other parasites or host DNA. The polymerase chain reaction (PCR) product were approximately 473, 352, and 397 bp, respectively. Subsequent Sanger sequencing revealed the molecular identification of R. echinobothrida, R. tetragona, and R. cesticillus. The primers usefully can be used for detecting cysticercoids for all parasite stages in pigeons and other poultry for epidemiological surveys, as well as for the management and control of infection.
This study was conducted to evaluate the effect of foliar fertilization and seaweed extract on floral growth characteristics and the production of corms and cormels in Freesia hybrid L. under plastic house conditions during the 2023–2024 autumn season. The study, designed as a factorial experiment with a randomized complete block design and three replicates, evaluated the effects of nano-fertilizer (NPK) at concentrations of 0, 1, and 2 mg L⁻¹, It was obtained from local markets, and seaweed extract at concentrations of 0, 1, 2, and 4 mg L⁻¹ on the floral growth and yield of corms and cormels in Freesia hybrid L. Results revealed that fertilizer (2mg/L) and seaweed extract (4mg/L) significantly improved key traits, including floral stalk diameter, flower longevity on the plant, days to the first flower opening, and corm and cormels production. These treatments achieved the highest number of corms, the greatest corm weight, and the largest corm diameter. The results of the experiment showed that the interaction between the two treatments, specifically N2M3, significantly outperformed in most floral traits and the yield of corms and cormels.
This study evaluated the effect of adding different levels of grape pomace meal on growth performance and microbial population of broilers dietary. A total of 275 one-day-old ROSS 308 chicks were randomly allotted into five treatments. Each treatment had five replicates, with 11 birds per replicate. The control birds were fed a diet consisting primarily of corn and soybean meal. The four treatments were fed a similar diet with the corn meal partially substituted by 2, 4, 6, and 8% grape pomace meal. Results showed no significant effect of grape pomace meal was observed on body weight and weight gain at days 24 and 35. The birds fed an 8% grape pomace meal diet reported higher (P<0.01) feed intake compared with other treatments. The feed conversion ratio increased (P<0.05) by 6% and 8% grape pomace meal diets. The population of E. coli and total bacteria declined (P<0.01), whereas the number of Lactobacillus spp inclined (P<0.01) with increasing the amount of grape pomace meal in the diets. In conclusion, the study indicated that feeding grape pomace meal up to 6% showed no deleterious effects on the growth performance, and the number of Lactobacillus spp was increased.
