The experiment was conducted in the botanical garden of the Department of Life Sciences/ College of Education for Pure Sciences Ibn Al-Haitham for the growing season 2021- 2020 in order to study the effect of urea and NPK fertilizer on some physiological characteristics of watercress plants. The seeds were sown on 10/15/2020 in plastic bags weighing 10 kg of soil. The shoots were sprayed with urea at three concentrations (0, 50, 100) mg L-1 in two sprays, and NPK fertilizer was added as a ground addition at three levels (0, 100, 200) kg H-1 in two sprays in conjunction with urea spraying. The results of the study showed a significant effect for the single treatments. The treatment of spraying with urea at a concentration of 50 mg l-1 . was superior to, and the treatment of NPK fertilizer at the level of 200 kg ha-1 by giving them the highest values compared with the measurement coefficients, and in the interaction coefficients between the study factors, the treatment (spraying with a concentration of 50 mg l-1 with NPK at a level of 200 kg ha-1 ) was superior, and the highest values were recorded for the number of leaves, dry weight of leaves and concentration Chlorophyll and the percentage of carbohydrates, nitrogen, phosphorous and potassium in the leaves were (29.00 leaf-1 , 12.55 gm plant-1 , 44.67 SPAD, 16.33%, 4.50%, 0.51% and 4.29%) compared with the control treatment that recorded values (15.33). Leaf-1 , 7.0712.55 g, Plant-1 , 32.68 SPAD, 8.58%, 3.07%, 0.24%, and 2.56%) respectively. The experiment was implemented according to the complete randomized sectors (RCBD) and the 9 transactions were randomly distributed. Coefficients and with three replicates, so that the number of experimental units was 27, and the averages were compared according to the LSD test at the 5% probability level. Keywords: urea, NPK fertilizer, watercress

The experiment was conducted to study the effect of leaves extract of Salvia sclarea , Rosmarinus officinalis and Thymus vulgaris with 10% and 30% concentration on germination of seeds and growth of seedlings . The effect of these extracts on infection percentage of seeds decay and surface growth of Rhizoctonia solani . The results showed that the three extracts effected significantly to reduced percentage of seeds germination, acceleration of germination , promoter indicator , infection percentage of seeds decay and surface growth of R. solani especially in 30% concentration .

To investigate the effect of spraying some plant extraction and anti-oxidants on growth and yield of two cultivars of sunflower, a field experiment was conducted during fall season of 2009 and spring season of 2010 at the Experimental Farm, Department of Field Crop Science, College of Agriculture/ University of Baghdad. RCBD with three replications as factorial at two factors was used. First factor was cultivars Akmar and Shmoss, second was spraying with extraction of karkade at 25%, liquorices at 50%, vitamin C at concentration 1.5 mg.l-1 and nutrient which content 15 elements at concentration 15 % in addition to control treatment which sprayed with distilled water only. The result showed no significant differences between the two cultivar

This study was carried out at University of Baghdad - College of Agricultural Engineering Sciences - research station B during the fall season of 2019-2020, in order to evaluate the effect of Ozone enrichment and the foliar application of organic nutrient on nutrient and water use efficiency and fertilizer productivity of broccoli plant using the modified NFT film technology. A factorial experiment (2*5) was carried out within Nested Design with three replicates. The ozone treatment was distributed into the main plots which consisted of oxygen (O2) and ozone (O3). The foliar application of organic nutrients were distributed randomly within each replicate including five treatments, which were the control treatment (T0), Coconut wat

The results of the phytochemical analysis of the crude aqueous and
methanolicextracts of Myrtle (Myrtuscommunis), peppermint (Menthapiperita) and
Sweet basil(Ocimumbasilicum) contain active compounds : Phenols, Flavonoids and
Tannins and missing of Steroids and Coumarines in all extract but Saponins and
Alkaloids found in methanolicextract only, while terpens were present in peppermint
and basiland absent in Myrtle. Administratingto animals with different extracts

This study was aimed to determine the impact of Conocarpus erectus L. compost fertilizer, and some micronutrients on growth and production of potato. This research was conducted at one of the fields of the College of Agricultural Engineering Sciences - University of Baghdad. The experiment was implemented using factorial arrangement (4X3X3) within randomized complete block design with three replicates. Conocarpus fertilizer was represented the first factor with three levels (7.5, 15, 30 ton.ha-1), which symbolized (C2, C3, C4). Chemical fertilizer as recommended dose as a control, which symbolized (C1). The second factor was foliar spraying with three levels of iron (0, 100, 200 mg.L-1), which symbolized (F0, F1, F2).
