This field experiment was conducted at Research Station B, Department of Horticulture and Landscape Engineering, College of Agricultural Engineering Sciences, University of Baghdad, Jadiriyah during the fall season of 2019-2020 to evaluate the effect of cultivation dates and soil fertilization source on the growth, yield and quality of broccoli. A split plot design within the RCBD design with three replicates was applied as the Max F1 hybrid broccoli seedlings were transferred to the field at two dates 25, Sep. 2019 and 15, Oct. 2019, which were symbolized as A and B, respectively, and occupied at the main plot. After two weeks of cultivation, the soil fertilizers were applied three times during the season in 20 days between each application including Biohealth fertilizer at a rate of 1 and 2 kg per donum, symbolized as T1 , T2 and NPK nano fertilizer at a rate of 250 and 500 ml donum, symbolized as T3 and T4 , as well as the control treatment that was fertilized according to the fertilizer recommendation and symbolized as T0 . This factor was considered the most important (sub plot) and the number of plants per experimental unit reached 15 plants. The results revealed a significant effect under the combination of first cultivation date and the soil application of Biohealth fertilizer at a concentration of 1 kg dunum (AT1) on the leaves content of N and k, leaves number, leaves area, the diameter and weight of the main disc, the total yield, the total soluble solids percent (TSS) and the heads content of beta-carotene, which were recorded 3.96, 2.99%, 41.0 Leaf-1 plant, 227.44 dm2 Plant-1, 74.0 cm, 896.40 gm Plant1 , 37.35 Tons Ha-1, 11.00%, 6.95 mlg 100 gm wet weight-1, respectively, which did not significantly differ from the combination of the first cultivation date and the application of nano-NPK fertilizer at a concentration of 500 ml dunum (AT4) on leaves area, the weight of the main head, and the total yield, which were recorded 212.39 dm2 plant-1 and 884.55 gm plant-1 and 36.85 tons ha- 1, respectively compared to the second date of cultivation and the application of fertilizer recommendation (BT0), which gave 2.33, 1.68%, 34.0 leaves, 139.99 dm2 plant-1, 51.0 cm, 689.23 gm plant-1 and 28.71 tons ha-1, 8.17% and 4.57 mlg 100 gm wet weight-1, respectively.

Abstract : This research is concerned with studying the best type and method of irrigation as well as the best cultivated area to reduce the cost of producing dunums of wheat crop in Iraq , and was based on data taken from the Ministry of Planning / Central Statistical Organization About cost of wheat crop production for (12) Iraqi governorates except Kurdistan, Nineveh, Salah al-Din, Anbar) and the sample size (554) according to the cost survey carried out by the Ministry of Planning / Central Statistical Organization for 2017, The results of the research showed that there are significant statistical differences between production costs when using t

Show MoreA factorial experiment (2× 3) in randomized complete block design (RCBD) with three replications was conducted to examine the effect of honeycomb selection method using three interplant distances on the vegetative growth, flowering, and fruit set of two cultivars of bean, Bronco and Strike. Interplant distances used were 75× 65 cm, 90× 78 cm, and 105× 91 cm (row× plant) represent short (high plant density), intermediate (intermediate plant density), and wide (low plant density) distance, respectively. Parameters used for selection were number of days from planting to the initiation of first flower, number of nodes formed prior to the onset of first flower, and number of main branches. Results showed significant superiority of the Strik

For this purpose, twenty five albino rats were divided into five equal groups, the first group was considered as control group. The other groups were given magnetized water with intensity of 250, 750, 1000, 1500 gause every day for 30 days. Then the animals were sacrificed and the histological change on heart, lung and spleen was studied. Histopathology of heart in rats treated with magnetic water with intensity of 250, 750, 1000, 1500 gause showed no clear pathological lesion. Lung section of rats treated with 250 gause of magnetic water showed no pathological lesion, while lung section belongs to rats group given
