A study was carried out to determine the population fluctuations and dispersion of green lacewings and aphids inhabiting pomegranate orchards in Assiut, Northern Upper Egypt, during the 2021 and 2022 growing seasons. A yellow sticky trap was used, and five directions corresponding to the cardinal directions and center were selected. The population density of the green lacewings and aphids recorded three peaks in both growing seasons. Statistically, the correlation coefficient (r) value between the average number of adult green lacewings and aphids was negative and non-significant (r= -0.08834, P= 0.2135) and the coefficient of determination (R 2 ) was 30.97% during 2021 growing season. However, the correlation coefficient (r) was positive and highly significant (r= 0.30901, P= < 0.0001), and the coefficient of determination (R 2 ) was 12.92 % during the 2022 growing season. The correlation coefficient (r) values between the average number of adult green lacewings and ambient weather factors differed in both seasons. In both seasons, the maximum average number of adult green lacewings was in the center. The maximum average number of aphids was in the east during the 2021 season and in the north during the 2022 season. The most preferred direction for green lacewing adults was the east northern side in both seasons. Aphids preferred the east northern side and the northern east side during 2021 and 2022, respectively. In conclusion, determining natural enemy fluctuations and preferred directions are important for the successful Integrated Pest Management (IPM) approach.","PeriodicalId":115841,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123870168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tallest plant, the highest number of leaves per plant and the highest plant fresh weight were obtained from Dash, F 1 hybrid and SCO-017 F 1 hybrid when sowing on the first planting date (1 Nov) in the first and second season, respectively. These results may be due to the favorable weather with the first planting date and the adaptation of these F 1 hybrids to these conditions.

The goal of the study was to determine the applying various potassium sources to Sultani Fig trees' vegetative growth, yield components, and fruit quality. Data showed that when compared to untreated ones, the application of various potassium fertilization sources considerably enhanced leaf area, shoot length, and shoot thickness. Additionally, yield, ripeness, and fruit quality were all improved by all investigated potassium fertilization sources. The usage of potassium thiosulfate led to the maximum values of fruit weight, length, and diameter being noted. Between all examined treatments, there were no appreciable variations in fruit length or fruit diameter. The highest TSS and reducing sugar values, as well as the lowest titratable acidity values, were produced by vinasse and potassien. Additionally, no appreciable variations were discovered between them. One may deduce that in order to improve some vegetative development, high yield, and good fruit quality, different potassium fertilization sources were required twice a year. Therefore, from an economic perspective, vinasse and potassien are preferred. Due to reduced pollution and a lower overall cost of production.","PeriodicalId":115841,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124968486","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research aimed to study the impact of modern technologies on economic efficiency of wheat crop in the New Valley Governorate, To achieve this goal, a cluster sample was drawn from Al-Kharga district, divided into two groups according to the cultivated wheat varieties, each group was divided into sub-groups representing farmers who used mechanization. Using the analysis of variance method to compare the different technological groups in terms of economic efficiency. Results show that the third technological combination, which represents farmers high productive seeds with the use of agricultural mechanization, was superior to its counterpart from other combinations. Therefore, the study recommended encouraging farmers to adopt the idea of using the agricultural machine in addition to the high productive seeds in producting wheat crop to included in all cultivated areas in New Valley Governorate.","PeriodicalId":115841,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133436168","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It causes a high damage to the legumes by decreased dietary values, germination and seed weights. Using synthetic insecticides for controlling stored grain pests have a lot of problems for humans and environment. Therefore, the mixing seeds laboratory experiments were conducted to study the efficacy of certain alternative safety compounds against C. maculatus such as Beauveria bassiana , Metarhizium anisopliae , ascorbic acid, boric acid, talc powder and kaolin compared with an organophosphorus nervous insecticide, malathion 1% dust, that recommended in Egypt for controlling stored grain pests. The present results showed that the malathion was the highest toxicity effect against cowpea beetle adults with LC 50 (3.89 ppm) after 3-day post treatment. However, the boric acid was the lowest toxicity effect with LC 50 (72855 ppm) after 6 days post treatment. The other tested materials showed moderate effects. These results indicate that malathion is still having high effect against cowpea beetle. The toxicity of bio-insecticides ( M. anisopliae and B. bassiana ) after 6days were more than toxicity malathion 1%dust after 1day.Wheraes, the toxicity of bio-insecticides ( M. anisopliae and B. bassiana ) increased with increase of period of exposure from 2 to 6 days high rates about 28 times, 31 times, respectively. The findings showed that the tested compounds have a promising insecticidal activity against C . maculatus and can be used as possible alternatives to synthetic chemical insecticides such as malathion for the control of stored product insects.","PeriodicalId":115841,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116402300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiments were carried out at Hawamdia sugar refinery factory, Giza Governorate, in the General Administration for Quality and Control, during September and October 2022. The results showed that the rate of decolorization of the samples increased with the increase the concentration of the additives.

While the best color removal of the syrup was 35.2% when ammonium persulphate at a concentration of 800 ppm was added to outlet syrup of talodora when compared to color of outlet syrup of talodora. On the other hand, it became clear that the removal color of the syrup when adding the material at the same concentration to the treated syrup was 70.2%, when compared to the color of the syrup inlet talodora.
