THE ECONOMIC AND SOCIAL IMPACTS OF THE DEVELOPMENT OF THE HUMAN RESOURCES IN THE EGYPTIAN RURAL’ AREAS
The research aims at examine the extent to achieve the desired objectives for the development of village and rural human development and the human element, which did not take adequate attention, especially in the aspect of improving the quality of life in spite of the expansion of services horizontally. There are also many evidence of the existence of a development gap between rural and urban areas, and the most important manifestations of this deficiency, illiteracy and poor health conditions, and the spread of unemployment and lack of employment opportunities. As it turns out there is a strong correlation between the human development index and all of the education manuals on GDP and guide health, has turnover of the link between the human development index and all of the evidence mentioned as 0.95, 0.84, 0.79 respectively, and All transactions have moral link at 1%. It is clear that the relationship between education and human development index, where the power that education guide associated HDI extrusive very strong link, followed by the gross domestic product guide, then the life expectancy index. It is clear from this that it must be focus on education and reform and to promote it in the countryside, The most important component of the human development index factors. found evidence also of statistical moral relationship regression to the influence of both the education and health guide and GDP on the Human Development Index, it has been possible to reach the relationship regression and showing moral influence exponential previous variables on the Human Development Index, a logical relationship also indicates coefficient of determination rate to be 98% of the changes in the value of the HDI due to change in the three sub-directories. It emerged from Manuitin test results for comparison to the values of the HDI revised each and Lower Egypt face and Total Republic that there is no significant difference between the Upper and sea at the moral level of 5%, as well as there was no significant difference between the Lower and Egypt on the same moral level, but that there significant difference between Upper Egypt and the moral level of 5%, which means that there is a difference between the normal human development index and revised between Upper Egypt and the total Republic.

A COMPARATIVE ECONOMIC ANALYSIS OF BROILER LITTER USAGE ALTERNATIVES AS A SOURCE OF FERTILIZER AND A SOURCE OF ENERGY PRODUCTION IN JORDAN
The increase of broilers production in Jordan makes it urgent to study broiler tiller produced. So, the study uses the economics of broiler litter concerning its usage as a source of energy production or as a source of fertilizers. The reuse of broiler litter (BL) will reduce the environmental impact. This empirical term paper used the different alternatives to manage broiler tiller. Many assumptions have been made to reach the feasibility of managing broiler litter. The results showed that the cash flow of using litter as a source of fertilizer was higher compared to use it for energy production for the years of study (1992-2014). The use of litter as a source of fertilizer as a source of fertilizer is more feasible than being used as a source of energy. The study recommended that the collected litter of broiler farms should be treated through specialized party to increase the economic feasibility and minimize the environmental effects.

GREEN MARKETING AS A RECENT ATTITUDE TO ACHIEVE SUSTAINABLE DEVELOPMENT
Environmental issues is an important topic nowadays as almost every country’s government and society has started to be more aware about these issues. This leads to a trend of green marketing used by the firms /producer in order to gain profit and protect the environment, Green marketing is the process of satisfying the needs and wants of customer’s in a way which can bring benefit or profit for both the producer and the society by reducing detrimental impact on the natural environment by providing less environmental harmful and/or more environment friendly products to the respondents, green marketing tools such as eco-label, eco-brand and environmental advertisement will make easier perception and awareness of green products attributes and characteristics, consequently, guiding them into purchasing environmentally-friendly products. Applying these policy tools plays an essential role to switch customer’s actual purchasing behavior to buy environmental friendly products, therefore, reduce the negative impact of synthetic products on the environment. The aim of this research was to know the respondents awareness of green marketing and its impact on sustainable development and to assess the attitude of respondents towards green marketing and sustainable development. A sample of (150) respondents was chosen from (5) super markets for administering well structured survey questionnaires. The analytical tools were used descriptive statistics, inferential statistical treatments such as percentages, means, and correlation analysis were applied to the data. From the research it was found that majority of the respondents did not have knowledge about green marketing because it is very new concept for respondents otherwise majority of the respondents agreeabout believing in the concept of green marketing, paying extra cost for green products also majority of the respondents strongly agreeabout supporting green marketing and sustainable development strategies The results of a correlation analysis between the respondents’ attitude towards green products with respondents’ demographics showed that, the respondents’ attitude towards green products was significant negatively correlated with Age, Education and income were significant positive correlated with respondents’ attitude towards green products, the research recommended that government and marketing organizations have to disseminate the importance of green marketing and enhancing the awareness at every level of stakeholders about green marketing.

EXTRACTION AND EVALUATION OF BIOACTIVE COMPOUNDS FROM SOME FRUIT AND VEGETABLE PEELS
Different research reports have revealed that food industry by-products can be considered as good sources of potentially valuable bioactive compounds. This study was performed to evaluate the antioxidant capacity of the peel extracts of pomegranate (PoP), mango (MaP), prickly-pear (PrP), Cantaloupe (CaP) and pea (PeP) using different solvent polarity (methanol, ethanol, ethylacetate and water) to particular attention to their content of total phenolics and flavoniods. Among all tested extracts, ethanolic extracts of PoP, MaP and PrP and aqueous extract of CaPand PeP were shown to exhibited a significant (p≤0.05) highest extraction yield, total phenolic and flavonoid contents and antioxidant capacity (measured by DPPH,ABTS and FRAP methods). The antioxidant capacity of different peel extracts was showed the following descending order, MaP>PoP>PrP>CaP≈ PeP. Also there was a strong positive correlation between the DPPH, ABTS, FRAP values and total phenolic as well as, flavoniod contents of different peels extracts. Seventeen phenolic compounds were identified and quantified by HPLC-UV analysis in different peel extracts. Galic acid was identified as the major compound in MaP and PoP extracts, while it was rutin in the case PrP,CaPand PeP extracts. From the results obtained, fruit and vegetable peels can be considered as good sources of valuable bioactive compounds.

EFFECT OF ACIDIC MARINATION ON THE QUALITY CHARACTERISTICS OF SPENT HEN KOBEBA DURING FROZEN STORAGE
Marinated spent hen meats were used in the preparation of kobeba. The chemical, physicochemical, microbiological and sensory properties of kobeba were evaluated during storage at -18˚C for 5 months. Kobeba treated with lime juice had higher crude protein (14.03%), crude fat (7.78%), total ash (3.18%), carbohydrates (8.69%), cooking loss (5.62%), water holding capacity (3.41 cm2/0.3g) and plasticity (2.30 cm2/0.3g) and lower moisture (66.41%) and pH (5.96) than kobeba treated with propionic acid and acetic acid. Lime juice, acetic acid and propionic acid marination reduced total volatile nitrogen values by 25.82, 20.53 and 11.20% and thiobarbituric acid values by 33.82, 25.37 and 18.38%, respectively. Lime juice followed by acetic acid was more effective in reducing total bacterial, psychrophilic bacteria and yeast and mold counts than propionic acid. Kobeba marinated with lime juice had higher rating scores (7.68-7.98) for all sensory properties than kobeba marinated with propionic acid and acetic acid. Total volatile nitrogen, thiobarbituric acid, pH, water holding capacity and cooking loss of kobeba were increased as storage period increased. However, plasticity had an opposite trend. Water and fat retention of kobeba were not affected by storage period. At the end of storage period, kobeba had rating scores described as like slightly (6.19-6.45) for all sensory properties.

PRODUCING PROMISING PEA LINES THROUGH RE-SELECTION FOR YIELD AND QUALITY FROM MASTER B CULTIVAR
This investigation was conducted at Barrage Station (BHRS), Horticultural Research, Kalubia Governorate, Egypt, to get some new and promising pea lines (Pisum sativum L.) using pure line selection method on the basis of genetic variability. Selection was performed between or within four pea populations of Master Bcultivar. The populations were collected from four different regions in Egypt and subjected to selection procedure during 2012/2013, 2013/2014 and 2014/2015 growing seasons. The investigation intended to study different traits of growth and yield and its components viz., No. of days to flowering, No. of first flowering node, plant length, No. of branches per plant, pod length, pod width, pod thickness, pod weight, No. of seeds per pod, weight of seeds per pod, No. of pods per plant, weight of 100 seeds, shelling percentage, pod yield per plant and seed yield per plant. The target of this study was to improve pea yield and its components as well as earliness of yielding. The analysis of variance revealed highly significant differences among genotypes for most of the studied characteristics, indicating ample scope of selection. Most characteristics showed a higher heritability coupled with higher genetic advance through two cycles of selection indicating that these characteristics are stable and can be improved through selection based on phenotypic observations. Twenty lines were obtained from selection program and were compared against the baseline populations in addition to check cultivar (Entsar1).Results showed significant differences among lines for most studied traits. Selection program resulted in genotypes or lines given symbols of H3, G7, N1, N3, G2, G1 and K2 that considered promising lines. These lines have good pods traits, higher productivity and earliness of flowering. Simple correlation coefficient analysis revealed that greater emphasis should be given to the traits of No. of branches and No. of pods per plant along with pod length, pod width, No. of seeds and weight of seeds per pod for yield improvement.

A STUDY ON THE DIFFERENTIATION BETWEEN ORANGE TREES DIRECTIONS ON THE CITRUS LEAFMINER, PHYLLOCNISTIS CITRELLA STAINTON (LEPIDOPTERA: GRACILLARIIDAE) AND THE COMMON PREDATORY SPECIES, IN QALUOBIYA GOVERNORATE
Field studies were carried out to study the effect of the different four directions (East, West, North and South) and the middle of the orange trees on the occurrence of the citrus leafminer, Phyllocnistis citrella Staint. (Lepidoptera: Gracillariidae), attacking orange orchards during the period extended from the beginning of July, 2015 until the end of June 2016. Also, to determine the common predatory species occurred in navel orange orchards in Qaluobiya Governorate. The warmer months that have the highest temperature degrees and that months having the newly orange leaves, had the highest percentages of infestation by the pest. The obtained results revealed that, the South direction of the orange trees had the highest percentages of leaves damage by the citrus leafminer, P. citrella. Where, there were significant differences between the South direction (68.75%), in comparing with those of the West direction (64.42%), the North direction (60.58%), the East direction (54.58%) and the middle of the orange trees (45.38%). So, it is recommended to firstly begin the Integrated Pest Management (IPM) programs against the pest in this direction and at the suitable time. Moreover, the importance of the natural role of the common predatory species recorded in the orange orchard is obviously shown and must be encouraged and developed. The highest total numbers of all recorded predatory species were during July, 2015 (47 individuals) and April, 2016 (35 individuals). The recorded predatory species were the highest in the South direction (70 individuals), in comparing with those of the North direction (54), the East direction (50), the West direction (37) and the middle of the orange trees (20). True spiders were recorded as the most predators (114 individuals), in orange orchard and also in the same time of pest occurrence. The animal predatory species (true spiders and predatory mites) were the highest in their numbers (167 individuals), in comparing to the insect predatory species: Chrysoperla carnea, Scymnus sp., Coccinella undecimpunctata, Orius sp. and Metasyrphus sp., of lower individuals numbers (64 individuals). In general, from this study, it is also recommended to use the different predatory species such as: Chrysoperla carnea, Scymnus sp., Coccinella undecimpunctata and Orius sp., for P. citrella control firstlyfrom the South direction. Where, this pest controlcan be applied by mass rearing of these predators in the laboratory and releasing them in orange orchards against P. citrella or other related pests (such as the citrus aphids species and mealybugs). This approach is believed to be highly practical for use as one of the means of biological control with the frame work of suitable and safe IPM programs in citrus orchards in Egypt.

A STUDY ON THE WEEDS DIVERSITY ALONG MARIOTTEYA CANAL AT GIZA GOVERNORATE, EGYPT
This research aims to study weeds diversity among five represented habitats namely; field crops, orchards, canal banks, wastelands and water bodies along Mariotteya Canal, Giza. A total of 88 species belong to 74 genera and 27 families were recorded and identified with Egyptian floras and available checklists. The dicotyledons families were represented by (69%); while monocotyledons were (31%). The common families were Poaceae (26%); while both of Compositae and Leguminosae were represented by (8%). Three species were recorded from each of Apiaceae, Cyperaceae, Malvaceae and Polygonaceae and two species from Salicaceae and Amaranthaceae. In addition to, 13 families were monotypic. The annuals species were represented by (59%), perennial herbs were (30%); while trees, shrubs and biennials species were (7%), (3%) and (1%); respectively. The life form showed that, therophytes species were represented by (60%) followed by chamaephytes (14%) then phanerophytes (10%). The chorological ratios showed that cosmopolitan taxa had the highest contribution (25%), followed by pantropical (19%) then palaeotropical (14%). Based on species recorded among five represented habitats, the cluster analysis divided the studied habitats into three groups. Group one included field crops and orchards habitats. Second group contained canal banks and wastelands habitats; while third group included water bodies' habitat. Moreover, field crops and orchards habitats showed the highest similarity value (0.614) followed by (0.559) between canal banks and wastelands habitats. On the other hand, there was no similarity between species of water bodies' habitat and species of the other habitats.
