Abstract: 

This study was conducted during February and March of 2021 in the labs of department of food sciences, Faculty of Agriculture, University of Aleppo, in order to study the effect of adding different percentages of potato starch on the physiochemical properties of boiled luncheon made from chicken thigh meat. The result,showed,the adding potato starch to luncheon , increased in the moisture and carbohydrates and decreased the  protein, fat and ash., in another hand, the hightest starch added was resulted a high percentage of moisture and carbohydrates significantly at a significant level (P <0.05) in the final product, and the proportion of the remaining components decreased significantly. The addition of starch in different proportions increased the product’s ability to bind water, reduced the volume water separated, and improved the consistency of the final product compared to the control. Adding starch led to a decrease in the loss during the boiling process, as the more starch added, the lower the loss in the boiling water. It was also observed that the addition of starch increased consumers’ acceptance of the final product, and the best organoleptic properties were at 1%.

Keywords: broiler thigh meat, potato starch, boiled Luncheon, chemical properties, physical properties.

Abstract:

The study was conducted at Alsonawbar station of the Agricultural Scientific Research Center in Lattakia/ Syria on Maize (Zea mays L.) during 2021summer season, to estimate the efficacy of some insecticides and bio-pesticides in controlling corn stem bores sesamia sp and Chilo sp and its reflection on production. The experiment was laid out in eight treatments: (control, spraying with Oxamyl،Chlorpyrifos، Chromafenozide، Emamectin Benzoate, and bio-pesticides: Bacillus subtilis and two isolated of Beauveria Bassiana (b8, b10)). Results showed that all tested pesticides reduced the Infestation percentage even after two weeks of spraying. The highest effective pesticide was Chromafenozide 88% after two days of spraying. The tested pesticides varied in their effect on the production parameters. B. Bassiana b(8) treatment outperformed the rest of the treatments with an average production of 3.760 kg/plant, the number of the cobs also affected, where the highest number of cobs was recorded in Chlorpyrifos and B. Bassiana b(8) 19.33 and 18.00 cob/plant respectively. As for the length of the cob; B. Bassiana b(10) treatment outperformed the rest of the treatments and recorded 19.23 cm/cob.

Abstract:

This study aimed to identify the effect of different concentrations of indole butyric acid IBA and Humic acid HA at rates (0, 200, 400, 600) and (0, 15, 30, 45) ppm, respectively, on the of sugar cane Saccharum officinarum L. In terms of rooting percentage, number of roots, length of roots, fresh and dry weight of roots, number of leaves/plant, number of stems/plant, plant height, fresh and dry weight of the vegetative growth. The experiment was carried out using randomized complete blocks (R.C.B.D) in three replications. The results of the experiment showed that soaking the cuttings in indole butyric acid IBA led to a significant increase in the rooting rate at a concentration of 200 ppm. The results also showed that the other of the studied traits were significantly affected, reaching the highest value with significant differences for the number of leaves, number of tillers, plant height, fresh and dry weight of the shoot system at concentration 400 ppm compared to the control, while the difference between the different concentrations of IBA did not reach the significant level. The results also showed that soaking the cuttings with humic acid led to a significant increase in all measures of root and vegetative growth studied, where the treatment of 30 ppm recorded the highest values with a significant superiority compared to the control.
Key words: Indole butyric acid IBA, humic acid HA, measures of root growth, measures of vegetative growth and sugar cane Saccharum officinarum L.

Abstract:

The research was carried out at the Jeb Ramleh Station (Al-Ghab Research Center) in Hama province in a 1000 m2 square for the 2019 and 2020 seasons to evaluate the efficacy of the predator Serangium parcesetosum Sicard (Coleoptera: Coccinellidae) for controlling the cotton whitefly Bemisia tabaci Genn. (Homoptera: Aleyrodidae) on eggplant in cages and in the open field. The S. parcesetosum was released in three times (29/7, 20/8 and 4/9/2019) for the 2019 season and on (16/7, 23/7, 29/7) for the 2020 season at a rate of 2 adults / plants in cages and 100 adult predators/ 1000 m2 per time. The data were recorded weekly, after the first release of the predator’s release, when the immature stages of the cotton whitefly (eggs, nymphs) were recorded on an area of 1 cm2 from the under the surface of the leaves, which were randomly selected from the top, middle and bottom of the plant. The mortality, parasitism, and emergence ratios of whitefly adults were also calculated within an area of 5 cm2 from the underside of leaves. The intensity of adult and immature stages of whitefly was significantly decreased after the sixth week of release in the two treatments of the predator S. parcesetosum compared with control without release either in the open field or in cages. The average death rate of nymphs of whitefly was more than eight times greater in treatments of the predator compared to the control. The results showed the ability of the predator to control the cotton whitefly population on the eggplant in Hama, Al-Ghab area.

Abstract:

Bio fertilization is one of the ways to enhance plant growth traits. The aim of this research is to isolate and characterize bacteria from the rhizosphere of the celery plants and study some of their growth-promoting properties The bacteria were isolated and were identified based on morphological and biochemical tests. the results showed that 45 bacterial isolates from the rhizosphere of celery were described. And All the bacterial isolates possess growth-promoting properties in varying proportions, as (96) % of them were able to fix nitrogen and (51) % dissolve for While the isolates produced the hormone indole acetic acid by (46%) and iron Siderophores produced by (75%), and (49%) were able to produce hydrogen cyanide. Later, then, the isolates with the most growth-promoting properties were identified, most of these isolates belonged to the genus Bacillus and Pseudomonas. The results in this research indicate the possibility of using these isolates in agricultural practices as bio-fertilizers to encourage the growth of different crops, after being tested on agricultural crops.

Abstract:

A field experiment was conducted to evaluate the influence of treated organic residues additions (biochar (B) and treated sewage sludge (TSS)) on growth, flowering and corm production of Freesia hybrida grown in calcareous soil, at Lattakia, during the seasons 2018- 2019 and 2019- 2020. The experiment included 5 treatments: (T1: Control without any additions, T2: mineral fertilization of NPK (30:20:20) g/m2+ 2 Kg/ m2 of organic manure, T3: 2 Kg/ m2 of B, T4: 2,5 Kg/ m2 of TSS and T5: (1,25 Kg\ m2 of TSS+ 2 Kg / m2 of B). The treatment T4 achieved close results to treatment T2 with no significant differences in between of almost studied vegetative parameters (plant height, leaf number, leaf area, leaf content of total chlorophyll). No significant differences was recorded between T2 and T5 for all qualitative flowering characteristics( number of spikes plant-1, number of flowers spike-1, flower stalk’s length and diameter and flower height), while early flowering was recorded in T4 and T5 along with longer flowering duration as compared to T2. Results also showed that all fertilization treatments were superior to the control treatment T1 for all studied parameters of vegetative growth and flowering. Treatment T5 achieved the highest percentage of cormels < 1 cm in diameter (50,26%) and was significant superior to all other studied treatments.

Abstract:

We often witness annually many sites within the precincts of public roads, especially in the green belts sites, traces of burning dry weeds in order to get rid of them and prevent their spread. The research studies the resulting effects on plant biodiversity as a result of doing this process. The research method relied on the field follow-up of the development of plant life for each of the terrestrial herbaceous species and the planted companion trees that were directly burned in the summer and then at the beginning of the spring within selected samples, in which random table readings were taken to determine the dominant herbaceous species. The study proved that the method used in this site was useless. On the contrary, its use led to the burning of most of the accompanying trees. The results of the research recommend that you should search for ways to control other than the burning process, especially in previously wooded sites. But if the method of burning is the only method that can be applied, then before carrying out the burning process, the nature of harmful herbaceous plants and their resistance to burning processes must be known, as well as the nature of the accompanying trees and their sensitivity to fire.
