This work was carried out at the Glass House at the Faculty of Agriculture/ Anbar University in the period between 2016 to 2017 Nano-iron and dry yeast extract were added to evaluate the response of maize productivity. Three concentrations of nano-iron, 0, 50, and 100 mg, were sprayed on the leaves The yeast extract of three concentrations 0, 100 and 150 grams per liter were sprayed on the leaves. The results showed the superiority of the treatments that were sprayed with nanoparticles with the highest rate of chlorophyll, the seed protein ratio and the percentage of seed oil. Significant levels were also recorded when spraying the plants with dry yeast extract. The interactions of 100 mg of nanotube and 150 g / l dry yeast extract chara

     The external signals are used as elicitors that can modify the levels of secondary metabolites production and trigger the biotechnological enforcements to improve plant production. In this study, sodium chloride NaCl was used as a stimulating factor for the production of beta-carboline alkaloids, harmine and harmaline, in Peganum harmala. The in vitro induced callus of P. harmalain was used as a source for alkaloid production in the stimulating experiments with sodium chloride. The results illustrated that 2 mg.l^-1 of NaCl increased the fresh and dry weight of callus with an average of 944.30 and 72.0 mg, respectively. In a comparative analysis through Gas Chromatography (GC)

    The experiment was conducted in the glass house in a  nursery at the growth season 2013.The experiment was designed by  the Completely Randomized Blocks Design(CRBD).The seeds of two varieties of eggplant were studied.They were : 1.Lot (Number)Melaneana  an American species,2.Aydinsiyah a Turkish species.We used three periods of water stress(1,8 ,16)days  respectively, and three concentrations of proline acid (0,50,100) ppm using three frequents for each treatment.The experiment contained 54 experimental unit.The seeds were planted on the 30th/8/2013 in the glass house of the nursery, a month later, we put the plantelet in pots with good  fertilized soil in the glass house.Some growth features were

This study was conducted in the botanical garden, Department of biology, College of Science / Mustansiriyah University in spring season, where the starts from (15 February to 15 March, 2019). Under the natural environmental conditions in the greenhouse in order to evaluate the effectiveness of some plant extracts as a promoter for rooting the apical stem cutting of rosemary plants at different concentrations compared with the IBA growth regulator. Plant extracts are Parsley (Petroselinum crispum), Dill (Anethum graveolens) and date palm fruits (Phoenix dactylifera) were used with concentrations (0, 1.25, 2.5 g / l). The IBA concentration was (100 mg / L) with dipping time 24 hour for all treatments. The following measurements were taken aft

The present study was conducted to determine the effect of different concentrations of putrescine and spermidine at all stages of regeneration (callogenesis, somatic embryos multiplication, germination and rooting)) of date palm cultivar Barhee. Shoot tips were eradicated from 2-3 years old offshoots, surface sterilized and inoculated onto Murashiege and Skoog, 1962 (MS) medium supplemented with 20 mg/L 2,4-D and 3 mg/L N6-2-isopentyl adenine (2ip). Primary callus was obtained after 24 weeks on the nutrient medium. Calli were then transferred onto fresh MS medium containing 0.0, 50, 100 or 150 mg/L of putrescine or spermidine individually. Results were recorded after 12 weeks. A significant increase in embryonic callus fresh weights reached

A field experiment was carried out in one of the agricultural fields in Thi Qar governorate in Nasiriyah during the winter season 2017-2018 The aim was to investigate the effect of foliar application of seaweed extract on yield and quality of four varieties of broad bean .The design of field experiment was (RCBD) in factorial experiments with three replications in two factors. .The first factor included four broad bean cultivars (Luz de otono – Grano Violtto -local - Aquadols. ( The second factor included four sprayed extracts of the seaweed extract (1, 2, 3 and 4 g L -1) In addition to the comparison treatment in which the plants were sprayed with distilled water only. . The plants of the broad bean that were sprayed with seaweed extract

Carnitine is a regulatory amino acid, necessary for the metabolism of long-chain fatty acids in the ß - oxidation, and it is important in the organization of the work of the blood brain barrier, and is very important in the treatment of infertility and sexual apathy. This study was conducted at the Poultry Farm of the Department of Animal Resource, College of Agriculture, University of Baghdad during the period from 15/2/2011 to 1/8/2011. The aim of this study was to investigate the effect of dietary supplementation with different levels of L - carnitin e on semen characteristics of guinea fowl male. A total of 24 guinea fowl male, 30 weeks of old were used in this study. Birds were randomly distributed into 4 groups (C0, C100, C200, C300)

The  two  i nsecticides  Nogos and  Sumicidin  were  tested  for  their activity  against larvae  and  eggs  of  Culex  pipiens under  laboratory conditi on.

Third  instar  larvae  were  exposed  for  24, 48 and  72.  hrs  to five concentrations  each insecticide  test: 0.0005, 0.005, 0.05, 0.5 and  1.0 ppm. The same concentrations were used to test the eggs hatching.

The  results showed   that Nogos  was more effective  than  Sumicidin. This insecticide (Nogos)  demonstrated  larval  mortal ities (94%) after

24  brs and (9

  The study was designed to invetigate the effect of two plant growth regulators (GA3 and IAA)on growth and leaves volatile oils of sweet basil .      The plants were treated with 200ppm concentration for each of the bove regulators after 2 monthes  of planting ,after 2weeks of the first treatment and after month of the first treatment .     The results showed an increase in plant height 25,35% ,number of large leaves 20,40% and percentage of volatile oils 200,100%respectively after one month of first treatment.
