Two field experiments were carried out at a Private Farm near Elzarka city, Damietta Governorate, during the two successive summer growing seasons from march to November 2013 and 2014 to study the effect of organic manure treatments (control, 25 m 3 /fed, 50 m 3 /fed) on growth, yield and quality of bitter gourd (Momordica charantia L.). The field experiment was laid out in a Randomized Complete Block Design with three replicates. The most important resulted obtained from this investigation can be summarized as follows : Organic fertilization of bitter melon plants with cattle manure at the rate of 50 m 3 /fed significantly increased growth, yield, and its components, thus the highest values of these characters were resulted from adding the highest rate of cattle manure (50 m 3 /fed) in both seasons. It can be recommended that organic fertilizing bitter gourd with 25 m 3 /fed in order to increase bitter melon yield over the control treatment and reduce the environment pollution and production costs under the environmental conditions of Damietta Governorate, Egypt .

Two field experiments were conducted in a private farm at Kafr Saad district, Damietta Governorate, Egypt, during 2018/2019 and 2019/2020 seasons to study the effect of three sulfur rates (0, 125 and 250 kg/fed.) and some foliar application treatments (sulfur, selenium, chitosan) in addition tap water as a control and their interaction on broccoli growth, yield and quality. Obtained results revealed that sulfur fertilization at 125 kg/fed. gave the maximum values of No. of leaves, head diameter, total yield and head quality (chlorophyll a+b, vitamin C and total carbohydrates). Foliar application with selenium gave the highest means of No. of leaves, fresh weight of leaves, plant height, leaves area, head diameter, head compactness rate and chlorophyll a+b of head, while foliar application with sulfur gave the maximum values of leaves, head dry matter, total yield and vitamin C content, as well foliar application with chitosan gave the maximum content of total carbohydrates. Thus, it could be recommended that the combined application of 125 kg/fed. of sulfur with the foliar applications with sulfur (4ooo mg/l) or selenium (50 mg/l) or chitosan (3000 mg/l) in broccoli fields can be recommended to enhance productivity of broccoli plants and quality

Cities become crowded and open areas that children can utilize decrease; therefore, it is extremely vital to have play areas and gardens to meet children's needs and requirements. This study was carried out at all children's gardens, Damietta governorate in the north of Egypt during the period from (2016 to 2019). The aim of this study was to investigate and assess all children's gardens in Damietta governorate (New Damietta, El-sananya child and the family, The Child garden in the Woman and Development Association, Faraskour and El-Zarqa gardens) , for comparing them to the model children's gardens for distribution, location, area, design, existing structures, plants, equipment, toys and their safety and maintenance in order to diagnose the points of weakness and strengths of each garden for the necessary procedures to reach the possibilities of improving or establishing a new children's garden at Damietta governorate. The design for this study was a descriptive research design. The results showed that number of children's gardens at Damietta governorate aren't sufficient or fit with population density. All children's gardens are located at the main streets jammed with traffic that endanger on the children and some gardens like El_sananya face the bars of the train in addition to a great noise pollution except for new Damietta garden which take place at wide street and design closest for the model garden. All children's gardens area are very small if compared to the global rates as the child is allocated only 0.22 square meters / child., which isn't accordance the international standards for children under the age of six needs 8-10m 2 except for New Damietta garden where it is 20243 m 2 , The design of these gardens mostly does not follow the scientific standards, but it is determine by the available space and insufficient resources. Neglecting a large part of most gardens by plants optimally. Some poisonous and cactus plants have to be eliminated from the children gardens. Most of the play equipment in the studied gardens aren't safe for children use. They are made from unsuitable materials, not according to safety measures, crowded in limited. Inspection and maintenance of these equipment are lost. In addition, some electrical and mechanical toys doesn't subjected daily inspection and maintenance periodically which can hurt children. So it is necessary to establish model gardens or modify the existing gardens as recommended in this study in order to meet the standards of the model gardens. Finally the results of this landscaping study and the recommendations have to be presented to the local administration leaders in the city for consideration and benefit of the children.

Two field experiments were conducted at 2018 and 2019 seasons at private farm in Talkha, El-Dakahlia governorate, to evaluate the effect of soaking times of some nutrients and their interaction on vegetative growth characters, photosynthetic pigments, yield and tuber quality of potato. The experiment was arranged in split plot design in complete blocks randomized. This research included 15 treatments consist of three soaking times of nutrients (1 hour, 2 hours and 3 hours) and 4 nutrients application i.e., NPK, zinc (Zn), boron (B), Zn+B in addition control treatment (tap water). Obtained results cleared that soaking tubers pre planting 3 hours gave the maximum values of vegetative growth characters, photosynthetic pigments, yield and tuber quality. All nutrients application significantly increased measured parameters compared to the control treatment. NPK gave the highest values of vegetative growth characters, photosynthetic pigments, yield and tuber quality. Thus, It can be recommended that soaking tuber pre planting 3 hours with NPK enhanced potato growth, yield and quality.
