: The research aims to study the current situation of the dairy industry in Egypt and to estimate the economic efficiency indicators, production patterns and costs of the cotton cheese production plants. The overall trend of the current dairy situation indicators was estimated to show both morale )amount of production, amount of consumption, size of surplus/food gap, total value of production and net agricultural income of dairy and dairy products, average per capita consumption of dairy(. and immoral )self-sufficiency ratio(. The average cost of production inputs was found to represent the largest proportion of the average variable costs by about 78.83% of the average production cost, and total revenue per ton of white cheese was estimated at LE 40,843. The value of the pound spent per ton was about £0.145, and the value added per ton of cheese was estimated at £3,612. The ratio of total variable costs to total revenue was estimated at 71.1%. The sharp surplus amounted to 11,813.25 pounds, and the stimulus for the product was estimated at 13%. An estimate of the production function shows that the most influential factors for the amount of white cheese are the amount of milk and the number of workers. A correlation was found between the amount of production, the amount of milk and the number of workers in the function. Total productivity flexibility was about 1,053. The cost-benefit estimate shows the model's statistical morale, with a calculated value of F of 1164.2 and a coefficient of F of 0.987. The minimum cost volume was 22.6 tons, achieved by about 18% of the sample coefficient, the maximum profit was about 152 tons and no laboratory from the research sample reached it.

Shalateen is considered one of the strategic areas for the security of Egypt from the south-eastern side which requires agricultural development. The objective of this study is to evaluate the soil quality using the integration of remote sensing and GIS. Thus, geopedological soil map was generated including the required soil characteristics. Twenty-six soil profiles were selected to represent the different mapping units. Assessment of soil quality is based on three main quality indices, chemical index (CI), physical index (PI), and fertility index (FI). The results revealed that chemical quality ranges from high to low quality, where most of the study area has a moderate quality. Physical quality varies from high to moderate, where most of the study area is classified as high quality. Fertility index in the study area fell into moderate and low classes. Finally, integration of the three indices showed that the study area is classified as a moderate soil quality. These results can be utilised to plan for the agriculture development taking into consideration the limiting factors and the potential use of the entire area.

The effect of extraction systems (Continuous Process Three-Phases and press process) on quality properties of olive oil extracted from picual variety was studied. The oil yield, flow rate, acid value, peroxide value, refractive index, saponification value, moisture and volatile matter, fatty acid composition and specific coefficients of extinctions (K232, K270 and ΔK) were determined. The CP3P extraction system produced a high olive oil yield. According to the results that obtained, it could be observed that there were no marked differences between both extraction systems in view of oil values such as acid value, peroxide value and refractive index which showed almost the same results. Meanwhile, also the results showed a slight difference in fatty acids composition, relying on the extraction systems were used. the olive oil produced from the CP3P has high quality than the olive oil that produced from the PP extraction system. Olive pomace produced from PP extraction methods contains high natural antioxidants.

Two filed experiments were conducted during 2018/2019 and 2019/2020 in a private farm, Sennouris district, Fayoum, Egypt, to study the effect of sulphur and boron on morphological characteristics, plant water status (RWC and MSI), leaf photosynthetic pigments content, leaf N, P, K, S and B contents and yield and its segments of red beet plants (Beta vulgaris L.). The experimental design used was a split-plot in randomized complete blocks design with three replications. Two agricultural Sulphur (95% S) levels (0 and 150 kg fed-1) were distributed in the main plots, while boron concentrations (0,50, 100, 200, 300 and 400 ppm) were randomly allocated to the sub-plots. Each experimental unit covered an area of 16.8 m2. During soil preparation, sulphur was broadcasted, while boron concentrations were foliarly applied to run off, three times; 30, 45 and 60 days after seed sowing. Soil supplemented with 150 kg fed-1 sulphur gave the highest significant values on previously mentioned measurements as compared to soil without sulphur treatment, except leaf area leaf-1. Whereas, Soil supplemented with sulphur showed a decreased level of leaf chlorophyll b and roots yield fed-1 for < 4 cm diameter. Foliar application of boron at 200 ppm was significantly recorded higher mean values of previously mentioned measurements as compared to other concentrations. While foliar spraying with boron at concentration of 50 ppm gave higher values in number of roots for < 4 cm diameter per 1 m2 and the concentration of 400 ppm boron was given higher mean values in fresh weight of roots fed-1 for < 4 cm diameter.

In the present study, two of the Egyptian Artemisia monosperma and two Jatropha curcas genotypes were selected from Egypt, for genetics analysis by using four RAPD markers. The results indicated that the RAPD primers were able to amplify DNA fragments showing, polymorphic DNA amplification patterns among the genotypes. The data indicated that out of the total 134 bands, 57 were polymorphic (57%). The number of the observed bands ranged from two for the primer j.OPA_07, a.OPA_07 to one in the primer j.OPA_07, a.OPA_07 with an average of 2.3 across for the tested genotypes. Consequently, most of the two RAPD loci in this study were useful for the evaluation of genetic diversity between the two Egyptian Artemisia monosperma , Jatropha genotypes. However, it is worth mentioning, this value expresses the existence to different alleles of one or more loci of homologous chromosomes. Polymorphism data content (PIC) value of the Artemisia, Jatropha genomic RAPD indicated temperate to high level of in formativeness with average PIC value to 0.23 over all the tested RAPD loci primers, where it ranged from 0.29 by using to aOPA-07 to 0.27in jOPA-02 for all genotypes under research by a mean to 0.23. The genetic analysis of the three Artemisia ,Jatropha based on 2 RABD markers detected 53 separate specific alleles, It is noted that, largest number patented to the specific/unique alleles were of the genotype number G2 and G3 where 53 specific alleles were patented to this genotype only.

Olive leaves are considered a waste during olive oil extraction and appear as a good source of natural antioxidant because it contains a high percent of phenolic compounds. This work aims to evaluate the effect of olive leaves extract (OLE) on acceleration of lipid oxidation in refined soybean oil. The olive leaves extract was added to refined soybean oil with different concentrations (5, 10, 50, 100 and 200 ppm). The butylated hydroxytoluene (BHT) at concentration 200 ppm was used as a control. The refined soybean oil (SBO) samples treated with OLE and BHT which exposed to accelerated oxidation in the dark conditions in an oven at (70±3°C) for 72 hours. The olive leaves extract showed a high antioxidant activity like synthetic antioxidant (BHT) at 200 ppm by measuring the peroxide values (PV) and thiobarbituric acid value (TBA) during accelerated storage. The olive leaves extract approximately has the same strong antioxidant activity of the BHT when is used as natural antioxidant in soybean oil at 200 ppm.

The olive leaves extract approximately has the same strong antioxidant activity of the BHT when is used as natural antioxidant in soybean oil at 200 ppm.","PeriodicalId":12075,"journal":{"name":"Fayoum Journal of Agricultural Research and Development","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80195525","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}
