To investigate the effect of electric shock (ES) on morphological variations of faba bean traits, seeds of three varieties of the crop were germinated. When radical was 2-5 mm, seedling were soaked in a 1% NaCl solution for 3h, then transferred to glass container with same solution. Wire with two polar were connected to the container solution and AC current 220 V was switched on for 3,6 and 9 minutes. Seedling then washed and planted at the field in winter 2010-2011,. Factorial Experiment was arranged in randomized Complete Block Design (RCBD) with three replicates were used. Seeds were collected first season of treatments, including the treatment comparison and then planted in the winter season of 2011-2012.The results obtained in the first season causing morphological variations in most of the traits, electric shock for 9 minutes gave less day to flowering was 81.21 days, increase number of pods/plant 23.94 pod , number of seeds / pod 4.23 seed and seeds yield was 3716.42 kg/ha. Shock for 3 minutes early the flowering of plants in the second season was 74.16 days and the number of branches / plant 13.66 Branch ,number of pods / plant 14.5 Pod and gave the highest height of the plant 76.92 and 62.12 cm for both seasons, respectively. While shock for 6 minutes gave the highest seed weight in the second season, which not differ significantly with treatment comparison was also, characterized with superiority in the percentage of protein in the first season (23.1%).The Zaina variety was earlier in flowering (77.91 and 78.87 days) for the first and second seasons respectively, also gave the highest number of pods/ plant 24.91 in the first season, and highest number of seeds/pod 3.98 and 2.83 seed for two seasons and which did not differ significantly from other varieties Aguadulce and Local respectively and exceed seeds yield in the first season was 3433.99 kg / ha. Aguadulce variety was superior in plant height for two seasons77.91 and 62.12 cm, respectively. Local variety , gave highest percentage of protein which did not differ significantly with Aguadulce variety reached to 22.26 and 22.25% respectively, and in the second season showed the highest number of branches / plant 13.5 and number of pods/ plant 14.12 Pod. The interaction between the varieties and shocking treatments were significant, as given in Aguadulce variety for 9 minutes in the first season gave the highest seeds yield was 4261.02 kg / ha, while in the second season Local variety showed the highest seeds yield was 4873 kg/ha in a period of 6 minutes shock also the interaction in the first season with 6-minute period of shock was significant only in the percentage of protein was 23.98 and 23.38% for the varieties Aguadulce and Local respectively, and protein yield of Local variety was 1110.28 kg / ha in the second season. In conclusion different varieties gave different responses to period of ES indicating that one period of ES could not be recommended for all varieties due to differences in response .
Foliar application and seed soaking has been used as a means of supplying supplemental doses of nutrients, plant hormones, stimulants, and organic components. the effects of these applications have included yield increases, and improved drought tolerance, and enhanced crop quality, so A field experiment was carried out during spring seasons in 2019 and 2020 for styding Seed soaking and Foliar Application of Ascorbic acid, Citric acid and Humic acid on Growth, Yield and Active Components IN Maize. Randomized complete block design in split plots arrangement was used with three replicates. Main-plots were for seeds soaking with ascorbic, citric (100 mg l-1) frequently and humic at (1 ml l-1). Sub-plots were for vegetative parts nutrition with

To know the effect of bio-enhancer (zeolite), biohealth, mineral fertilizers and their interactions, the possibility of replacing mineral fertilizers with bio-enhancers and bio-enhancers, and their effect on some potato yield measurements. A field experiment was conducted at one of the field stations of the College of Agricultural Engineering Sciences, University of Baghdad, near the electronic calculator center, research station (F) in Al-Jadriya region in the loam mixture soil during autumn season 2021-2022 AD, It was designed using a completely randomized block design (RCBD) with three replicates. The factors of the study experiment included three levels of zeolite (0, 6 tons ha-1, and 12 tons ha-1), which were symbolized by (Z0)

Abstract: This study aims to investigate the effects of solvents of various polarities on the electronic absorption and fluorescence spectra of RhB and Rh6G. The singlet‐state excited dipole moments (me) and ground state dipole moments (mg) were estimated from the equations of Bakshiev -Kawski and Chamma‐ Viallet using the variation of Stokes shift along with the solvent’s dielectric constant (e) and refractive indexes (n). The observed singlet‐state excited dipole moments were found to be larger than the ground‐state ones. Moreover, the obtained fluorescence quantum yield values were influenced by the environment of the fluorescing molecule. Consequently, the concentration of the dye solution, excited singlet state absorption and

Show MoreTo 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

Thirteen treatments were formulated to evaluate the effectiveness of four applications of Phosphorus (0, 60, 60×2 and 120 Kg P. h-1) and three applications of Zinc (0, 25×2 mg Zn. L-1 and 50 mg Zn. Kg soil-1) along with inoculating seeds of bean with strains mixture 889 and 1865 and non-inoculated treatment, on nodulation, yield and protein content in seeds (N%). The results showed that inoculated plants exceeded on non-inoculated one in all the studied characteristics. While, P and Zn, applications at the rate of 60×2 kg/ha and 25×2 mg/L respectively, significantly, increased, nodulation, yield, protein content in se
