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 at a concentration of 4 g L-1 were significantly higher in all the traits under study, Record The average of 329.70 g and 2.68 tons -1 and 29.09% for the the weight of 100 soft seeds and the total number of seeds and the proportion of protein in seeds sequentially The varieties showed a significant difference between them in most of the studied traits. The local cultivars exceeded 100 soft seeds and the percentage of carbohydrates in the seeds while Luz de otono outweighed the total number of seeds and the superiority of Aquadols in the percentage of protein in seeds. The overlap also showed a significant effect between the cultivars With the extract of seaweed, where the plants of the class Luz de otono, which was sprayed with extract of seaweed at a concentration of 4 g L-1, significantly increased the total seed yield by 3.16 tonne-1 In the proportion of protein, the superiority of Aquadolus, sprayed at a concentration of 4 g L-1, reached 32.99%..

This study was carried out at University of Baghdad - College of Agricultural Engineering Sciences - Research Station B during the autumn season 2019-2020, in order to evaluate the effect of Ozone and the foliar application of coconut water and moringa extract on the growth of broccoli plant grown in 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 water with two concentrations of 50 (T1) and 100 ml.

Experiment was conducted using clay pots at botanical garden of Department of Biology/ College of Education for Pure Science / Ibn –AL- Haitham, University of Baghdad during the growth season of (2013-2014).The experiment aimed to study the effect of NPK Zn fertilizer in (15-15-15-1)% with the levels 0.2, 0.4, 0.6 grams per five kilograms soil based on (80, 120, 240 kg per Hectare)in some of morphological characters and yield of Vigna radiatia. The results showed a significant increase in plant height, dry weight, biological yield, economic yield, weight of 100 seeds, harvest index, absolute growth rate (AGR) were all increased and amount of output compared with control plants.

ABSTRACT
The results showed that the organic fertilizer mixture (1:1) 30 tons/ha with chemical fertilization recorded the lowest level of bulk density of 1.2 g/cm3, the organic fertilizer mixture (1:1) 30 tons/ha with chemical fertilization recorded the highest percentage of aggregation stability amounting to 16.17%, the organic fertilizer palm fronds recorded the highest level of ready water with an average of 5.50 cm3/cm3 and the organic fertilizer mixture (1:1) 30 tons/ha without chemical fertilization recorded the highest level of ready water as it reached 6.93%, the or

potential of sorghum residues alone or in combination with reduced rate of trifluralin
herbicide on weeds in mung bean field. The field experiment was conducted during
2014 season at the Research Farm of Biology Department, College of Science,
Baghdad University by using randomized complete Block design (RCBD) to test the
effect of sorghum residues at rates of 5 and 10 t ha-1 alone or in combination with
reduced doses of trifluralin (30 and 60% of recommended dose) on weeds and mung
bean crop. Weedy check and label rate of trifluralin (2.4 Lha-1) were also included
for comparison. Each treatment was replicated four times. Total phenolics
Pots experiment was conducted at the greenhouse of botanical garden belong to Department of Biology, College of Education for Pure Science, Ibn-AL-Haithum, University of Baghdad, for growth season 2018-2019. The aim of the experiment was to study the effects of foliar application of a-tocopherol concentrations (0, 50, 100, 150, 200 mg.L-1) on growth parameters and the activity of some antioxidant enzymes of wheat plant irrigated with sodium chloride concentrations (0, 75, 150, 225) mM.L-1. Salinity reduced plant growth parameter, plant height, flag leaf area, flag leaf chlorophyll content and increased the activity of antioxidant enzymes, superoxide dismutase and peroxidase. Plant growth parameters were enhanced by foliar application of a-t

This study was carried out to find out the effect of germination of broad beans and chickpeas seeds for different periods on their antinutritional factors content ( Trypsin inhibitor and Phytic acid ) and the chemical constituents of germination seeds compared with the control samples (ungerminated seeds) . The results indicated asignificant increase (P<0.05) in crude protein content as germination period proceeded.The highest values of 28.0% and 24.0% were reached on the sixth and fourth day for germinated broad beans and chickpeas respectively, The intial values were 25.6% and 23.5% for control samples, respectively. The content of raffinose,stachyose and verbascose were reduced as germination period proceeded, Stachyose and verbascose we

Present study is carried out to evaluate the effect of alkaloids extract of
Amaranthus gracilis on some biological aspects of the house fly Musca domestica to
find out the best way for their control. The highest mortality percentage on eggs of
the house fly was 83.3% at concentration of 10 mg/ml followed by 44.4% and
31.1% at 7.5 mg/ml and 5 mg/ml respectively. Results also referred that the
mortality rates of eggs, larvae, pupae were increased with increasing concentration.
The pupal weights were decreased with increasing of concentration.
