The experiment was carried out in the wooden canopy in the green garden of Biology Department , College of Education for Pure Science – Ibn AL –Haitham, Baghdad University, during the growing season of 2012- 2013 , to study the influence of foliar application of three concentrations of zinc (0,50,75)mg. L ¯¹ with four concentrations of boron (0, 25, 50, 75) mg. L¯¹ and their interactions on some growth parameters of vegetative part of chickpea plant. The experiment was designed according to Randomized Completely Block Design(RCBD)with three replications, results indicated that:- 1- Foliar application of zinc and boron caused a significant increase in the averaye of dry weight for the first harvest, No. of branches. plant¯¹, No. of flowers . plant¯¹ , the relative efficiency of fertilizer for the first harvest , the secondary productivity , the content of each nitrogen , phosphorus and calcium for the both harvests , percentage of protein for the both harvests and the content of total chlorophyll, compared with the control . 2- The interaction effect between the two elements was significant in the growth parameters and superiority of the treatment 75 mg . L¯¹ zinc and 75 mg. L¯¹ boron in giving the best value.
Poly methyl methacrylate PMMA polymer could be considered the main material that used mostly in the recent years in denture base fabrication. It commonly known by it is poor strength properties such as low impact strength. The aim of the present research was to enhance the performance of PMMA denture base through the addition of two kind of nanoparticles (nano particles that selected from artificial and natural sources). Nano -particles from both Al2O3 and crushed peanut Peel were used for comparing purposes.Various weight fraction used in this study for both kinds of the additive (1%, 2% and 3%). Moreover, in this work a study and evaluation in impact strength (I.S.) value were done before and after immersion. The new prepared nanocompo

Pot experiment was carried out at the College of Agriculture – Baghdad University during autumn season, 2007. 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

The Experiment was conducted during the fall of 2002-2003 at the botanical gardenor of biology Department, Ibn- Al Hiatham Education college Baghdad University to study the effect of two planting dates (23/10 and 6/ll 2002) with different concentrations of GA3 (100 and 200 ppm) on growth characters and the active material of two cultivars (Local and German) of chamomilla (Matricaria chamomilla L.) plants. Randomized complete Block Design (R.C.B.D.) was used with three replications . Each one of the experiment units 1x1m .The parameters study were plant height, no shoots, no inflorescence branches and nodes , leaf area and leaf area index and violate oil percentage. The result showed that planting date. At 23/10 give a significant
... Show MoreThe 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

Show MoreAn experiment was carried out on the fields of the college of Agriculture - Abu Ghraib, of a silty clay loam soil that has moisture of 15-16%, to study the effect of plowing and pulverization systems on some plant indicators of onion. The experiment included plowing systems with three levels (plowing with a moldboard plow, plowing by chisel plow and zero tillage plowing) as a primary factor. The second factor was that pulverization for only one time and repeating the pulverization twice through the use of the rotary tiller. The plant indicators of onion that are studied: plant length, onion diameter, onion weight and onion neck diameter. The experiment has carried out according to SPLIT PLOT design according to RCBD design by three replicat

This study was carried out to investigate the possibility of chickpea soaked water as a substitute for yeast in dough fermentation and its effects on sensory properties of the laboratory loaf bread. Chickpea was soaked for 24,48 and 72 hours at room temperature and used in proportion with or without yeast in dough fermentation . The results revealed that , as the percentage of soaked chickpea water substitution increased, the volume of the produced loaf bread decreased as compared with the control treatment (only yeast ).Best results were obtained by using soaked chickpea water for 24 hours in proportion of 1:1 soaked chickpea water : yeast regarding the sensory properties ,volume and leavening of the loaf bread.
