The chosen vines were 6-years-old, planted in a clay loam soil under surface irrigation system, spaced at 1.5 x 3 meters using spur pruning with quadrilateral cordons training and supported by Gable system. The total load was 48 eyes. The aim of this study was determined the influence of removal of some shoots after harvestperiod on carbohydrates content, wood ripening, C/N ratio in canes, growth and yield of Flame seedless grapevines. The design treatments was complete randomized blocks and involved four treatments, which included control (without shoots removal), 15% shoots removal, 25% shoots removal and 35% shoots removal after harvest period, by removal the shoots which developed from spurs during the growth seasons. The results showed that there were significant differences between the various shoots removal treatments after harvest period. Removal of shoots at 35% application and control treatment had negative effect on most parameters which were studied. On the other contrary, both of 15% followed by 25% application gave the best results in most parameters which were studied such as total carbohydrate contentin cans, wood ripping %, length and diameter of cans, C/N ratio, vegetative growth measurements such as shoot length and leaf surface area, total chlorophyll content in the leaves, yield and its components as well as chemical properties in grape berries.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-366910720190701Growth and Productivity of Fennel (Foeniculum vulgare, Mill) Plants as Affected by Phosphorus Rate and Nano-Micronutrients Concentration4834885354010.21608/jpp.2019.53540ENM.

The experiment included fifteen treatments resulted from the combination of three irrigation water levels (100%, 80%, 60% from ETc) and five antitranspirants (kaolin, CaCO<sub>3</sub>, MgCO<sub>3</sub>, green miracle and tap water (control)). The obtained results showed that irrigation with 100% from ETc was the best irrigation treatment and the negative impact of drought appeared on studied characteristics with decreasing water supply to become more serious under irrigation with 60% from ETc. The frequent foliar application of antitranspirants played a remarkable role in alleviating the hazard of drought stress. However, all antitranspirants had promotive effects, kaolin foliar application gave the best results on all studied characteristics. It improved vegetative growth, leaf chemical constitutes and increased seed yield and quality parameters under both non-stress and stress conditions. Moreover, Kaolin treated plants irrigated with 80% from ETc performed better even than untreated plants irrigated with 100% from ETc. According to findings of the current study, summer squash can be protected from the negative consequence of the drought by frequent foliar applications of reflective antitranspirants such as kaolin, as it proved to recover the growth as well as seed yield quality under water limitation conditions.

The findings showed that, deficit irrigation treatment (I<sub>3</sub>) was related with reduced vegetative growth aspects (canopy volume, No. of shoots /branch, Shoot length) as well as stomatal resistance, however transpiration rate was increased in both seasons, in addition, nano-silicon spraying at 300 or 200ppm caused a significant increase in previous growth aspects over the control.</span><span style="font-size: xx-small;">The combination between high or moderate irrigation rate (I<sub>1</sub> or I<sub>2</sub>) with nano-silicon spray at 300 ppm (S<sub>4</sub>) were more effective in enhancing growth parameters. In both seasons, deficit irrigation treatment (I<sub>1</sub>) decreased leaf mineral contents and increased leaf proline content. However, high concentration of nano-silicon markedly increased leaf mineral contents but reduced leaf proline contents. Both low and high irrigation rates (I<sub>2 </sub>and I<sub>3</sub>) or high concentration of nano-silicon (S<sub>4</sub>) and their interaction achieved the highest values of bound water and osmotic pressure and the lowest values of total and free water contents. Furthermore, the yield and components, water use efficiency and most of external and internal fruit properties were significantly increased under moderate irrigation (I<sub>2</sub>) or high concentration of nano-silicon and their interaction (I<sub>2 </sub>xS<sub>4</sub>), while, the percentage of fruit splitting was decreased. Finally, trees irrigated with moderate irrigation rate combined with nano-silicon at (300 ppm) enhancement the growth, yield and fruit properties.

Sixty rice genotypes were used in this research. A field experiment was conducted in a randomized complete block design with three replications at Sakha Agricultural Research Station, Kafr elsheikh, Egypt during 2017 and 2018 seasons. The results revealed that the Giza 178, GZ 9399-4-1-1-3-2-2 and Giza 177 exhibited the highest values of no.of filled grains panicle<sup>-1</sup> and grain yield t/ha. The mean square analysis for the rice genotypes was highly significant for all studied traits, indicating that the differences among the rice genotypes and their traits. Chlorophyll content, flag leaf area, number of panicles plant<sup>-1</sup>, panicle length and number of filled grains panicle<sup>-1</sup> showed positive direct effect on grain yield, while, rest of traits showed negative effect on grain yield. This indicates that more number of filled grains panicle<sup>-1</sup> is a highly reliable component of grain yield. Another important character with direct effect on grain yield is number of panicles plant<sup>-1</sup> and flag leaf area which showed positive direct effect on grain yield. Hence, number of panicles and filled grains panicle<sup>-1</sup> should be given a prior attention in rice improvement program because of their major influence on yield.

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<sup>2</sup> except for New Damietta garden where it is 20243 m<sup>2</sup>, 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.Mansoura University, Faculty of AgricultureJournal of Plant Production2090-366910720190701Influence of Sowing Dates and Foliar Spraying of Iron and Zinc on Sugar Beet Productivity in Salt Affected Soil5695735355410.21608/jpp.2019.53554ENManal S.

The treatments consisted of two sowing dates (August 1<sup>st </sup>and October 1<sup>st</sup>) and for micronutrients, without micronutrients, Zinc-EDTA (16 %) in concentration of 1g/l and Fe-EDTA (14 %) in concentration of 1.5 g/l were applied three times at 60, 75 and 90 days after planting. The combined analysis showed that the first sowing date (August 1<sup>st</sup>) surpassed the second one (October 1<sup>st</sup>) in all studied characters. Foliar application of Fe-EDTA at concentration of (1g/l) was more effective than foliar spray of Zn-EDTA at concentration of (1.5g/l) in improving root performance (length, diameter and fresh weight/plant) and juice quality as well as increasing root, top and sugar yields/fed compared with without treatment (control). The effect of interactions between sowing dates and foliar application of micronutrients were not statistically significant on the all studied characters.
