A field experiment was carried out during the twosuccessive seasons of 2012/2013 and 2013/2014 to study the effect ofcompost and biofertilizers, as well as, some vitamins and theirinteraction on Gladiolus grandiflorus cv. Carmen plant.Results showed that vegetative growth (leaf length, number ofleaves/plant and dry weight of leaves/plant), flowering aspects (lengthof spike, number of florets/spike and lower floret diameter) and cormsproductivity (corm diameter, corm dry weight and number of cormelsper plant) were gradually increased by increasing the level of compostfertilizer.All biofertilizers and vitamins treatments significantly increased allvegetative growth characters, flowering parameters and corm andcormels productivity in comparison with the control. Effectivemicroorganisms (E.M.) + active dry yeast (A.Y.) treatment seemed tobe more effective than other treatments in this concern.The use of high level of compost (21 ton/fed) in combination withcombined biofertilizers noticeably improved the different vegetativegrowth characters, flowering parameters and corms productivity ofgladiolus.

The present investigation was conducted at the nurseryof Hort. Res. Inst., ARC, Giza, Egypt during 2013 and 2014 seasons tostudy the effect of different pre-sowing seed treatments, viz., untreatedseeds (control), soaking in tap water for 24 h at room temperature,soaking in previously boiling water for 24 h at room temperature,boil/cold water dipping (thermal shock treatment), soaking inconcentrated H2SO4 for either 2 or 4 min (chemical scarification) andabration testa with rough emery paper (mechanical scarification) onseed germination and seedling growth of Powder Puff (Calliandrahaematocephala Hassk.) shrub.The obtained results indicated that most of the used treatmentsimproved germination % and velocity, mean germination rate,germination rate and vigour indices, seed viability and epicotyl lengthof germinated seeds, as well as seedling growth with varioussignificant differences compared to control in the two seasons, exceptfor thermal shock treatment which completely failed to inducegermination. It was also noticed that seed viability markedly decreasedas a result of mechanical scarification with emery paper to reach theleast values at all. Content of total indoles and phenols in the untreatedseeds was stable as they were not subjected to any treatment, but intreated seeds, it was increased where total indoles reached themaximum by soaking in either concentrated H2SO4 or boiling water,while these two treatments caused a nil increment in seed content oftotal phenols relative to control and other pre-sowing treatments. Inaddition, content of chlorophyll a, b, carotenoids and total solublesugars in the leaves of seedlings raised from the treated seeds wasgreatly increased, especially by chemical and thermal scarification.Generally, the mastery in all previous measurements was for soakingin either concentrated H2SO4 for only 2 min or boiling water for 24 h,as they recorded the utmost high means in the majority of measuredtraits in both seasons.Hence, it is recommended to treat seeds of Calliandrahaematocephala pre-sowing by soaking in either previously boilingwater for 24 h. or in concentrated H2SO4 for only 2 min. to obtain thebest germination and seedling growth.

This study was carried out in the Nursery ofFloriculture, Ornamental Horticulture and Landscape GardeningDepartment, Faculty of Agriculture, Alexandria University, during thetwo successive seasons of 2011 and 2012. The aim was to evaluate theeffect of growing media and mineral fertilization on growth of thelawn Paspalum vaginatum,L.Split-plot was the experimented design in three replicates, andsixteen in each. The main plot represented the growing media (A)100% calcareous soil (B) 50% calcareous soil:50% sand, (C) 50%calcareous soil:50% sewage sludge and (D) 50% calcareous soil:25%sand:25% sewage sludge. The sub-plot nitrogen levels were four (0.00(N0), 5.00 (N1), 10.00 (N2) and 15.00 (N3) g N/m2).The main results of this study can be summarized in the followingpoints:1- Generally, medium (C), consisting of 50% calcareous soil:50%sewage sludge with the addition of the fourth level of nitrogen(N3), gave the shortest time to complete covering and gave the bestresults of leaf blade length and the best results for the total dryweight of vegetative growth parts.2- The medium (B), containing 50% calcareous soil:50% sand withthe addition of the fourth level of nitrogen (N3) gave the bestresults in terms of roots volume.3- The media containing either 50% or 25% sand with the addition ofthe fourth level of nitrogen (N3) gave the best results in terms ofdry weight of roots.4- Chemical analysis showed that there were non significant effectsfor growing media on the total chlorophylls content and thenitrogen percentage in the leaves.5- Increasing nitrogen levels led to significant increases in the totalchlorophylls content of leaves and the nitrogen % in the dry matter.

This experiment was consummated under shade at thenursery of Hort. Res. Inst., ARC, Giza, Egypt during 2013 and 2014seasons to explore the effect of some pre-sowing treatments, viz.control (untreated seeds), seeds without mucilage, soaking in tap waterfor 24, 48, 72 h under ambient conditions, soaking in hot water (60-70C) for 24h, soaking in absolute ethanol (97%) for either 12 or 24 hand soaking in concentrated sulfuric acid (98.5%) for 3 min ongermination measurements of Elephant apple (Dillenia indica L.) seedsand growth of the produced seedlings.The obtained results have shown that seeds of control and thosesoaked in either hot water or ethanol for 24 h failed to germinate, whileseeds without mucilage and those soaked in ethanol for 12 h gave theleast germination percentage in the two seasons. The other treatments,however significantly improved germination %, with the superiority ofsoaking in concentrated H2SO4 for 3 min treatment, which elevatedsuch parameter to 100% in both seasons. Besides, germination % wasfound to progressively increase with elongating soaking period in tapwater to reach 100% in the first season and 83.33% in the second oneby the longest soaking period (72 h). The germination velocity andmean germination rate were accelerated and the indices of germinationrate and vigour, seeds viability and plumule length were significantlyimproved by some treatments used in this trial, but the prevalence wasalso for acid treatment which followed by soaking in tap water for 72 htreatment. Similarly, were those result of seedling growth traits andleaf content of chlorophyll a, b, carotenoids, total soluble sugars,indoles and phenols, as the soaking in concentrated H2SO4 for 3 mintreatment scored the best growth of the seedling and the highestcontent of the various constituents which was accompanied with theleast content of total phenols. Also, soaking in tap water for 72 hoccupied second rank.So, it advised to soak Elephant apple (Dillenia indica L.) tree seedseither in concentrated sulfuric acid (98.5%) for 3 min or in tap waterfor 72 h to obtain the best germination and quality of seedlings.

This investigation was conducted to investigate the response of Populus alba transplants to compost fertilization at four levels and Bio. and/or mineral NPK treatments (control, phosphorein, effective microorganisms (E.M.), phosphorein + effective microorganisms, a mixture of Bio. (phosphorein + E.M.) + 75% NPK and mineral NPK, full dose) on vegetative and root growth parameters and some chemical constituents. The obtained results indicated that, transplant height, stem diameter, whole transplant fresh and dry weights, main root length, fresh and dry weights of roots, as well as, chemical constituents including total chlorophylls, percentages of N, P and K were gradually increased by increasing the levels of compost fertilizer. Biofertilizers and/or mineral NPK fertilization treatments significantly increased all the previous parameters. Bio. + 75% NPK dose followed by mineral NPK (full dose) treatments were the most effective in this concern. The interaction between compost and Bio. and/or mineral NPK fertilization treatments was significant for vegetative and root growth parameters with the highest values for vegetative and root growth traits being obtained due to either compost fertilizer in combination with Bio. + 75% NPK dose or with mineral NPK (full dose)

An experiment was undertaken in the open field at thenursery of Hort. Res. Inst., ARC, Giza, Egypt during 2013 and 2014seasons to explore the effect of different water qualities (fresh, mixed (50%fresh + 50% sanitary water) and primary treated sanitary water), variousconcentrations of jasmine oil (0.0, 0.03 and 0.05%) applied as foliar spray,3 times with 15 days interval and their interactions on growth and chemicalcomposition of one-year-old seedlings of Australian pine (Casuarinaequisetifolia L.) and River Red Gum (Eucalyptus rostrata Schlecht.)cultivated in 16-cm-diameter black polyethylene bags filled with about 3.5kg of clayey soil.The obtained results have shown that all vegetative and root growthparameters of the used two trees were significantly increased in response tothe different sole treatments and interactions used in this study. A similartrend was also obtained concerning the leaf content of chlorophyll a, b andcarotenoids, as well as total soluble sugars, N, P and K in the stem, leavesand roots, as they were markedly increased by the various employedtreatments. On the other hand, content of Pb and Cd in the stem, leaves androots was increased as the level of sanitary water increased in irrigationwater, but they were gradually decreased with increasing jasmine oilconcentration in spray solution. In general, content of these two metals invarious plant organs was greatly less than their critical levels that inducetoxicity. So, no morpho-or physio-logical disorders appear on the plants ofthe two studied tree species. However, the prevalence in all previousmeasurements was for the combining between irrigation with mixed waterand spraying with 0.05% jasmine oil solution, as this combination gave thebest rate of vegetative and root growth and the highest content of pigments,total soluble sugars, N, P and K in plant tissues accompanied with the leastcontent of Pb and Cd elements.Hence, it could be said that primary treated sanitary water can be usedafter mixing with fresh water at equal parts in irrigation Casuarinaequisetifolia L. and Eucalyptus rostrata Schlecht. plants proved sprayingthem with 0.05% jasmine oil solution, 3 times with 15 days interval toachieve the best growth and highest quality.

An investigation was conducted under the open field condition at the Experimental Farm of Hort. Res. Inst., ARC, Giza, Egypt during 2013 and 2014 seasons to study the effect of some commercial liquid fertilizers; super blue-green (SBG) at the rates of 1 and 3 ml/l, Kalsin-A (K-A) at the rate of 1 ml/l and the combinations between the two levels of SBG and that of K-A on growth, density and chemical composition of seashore paspalum (Paspalum vaginatum Swartz) planted in 40-cm-diameter plastic pots filled with about 6 kg of sand and clay mixture (1:1, by volume) when applied as a foliar spray, 5 times with one month interval. The control plants were sprayed with tap water only. The obtained results indicated that all single and combined treatments used in the study markedly improved all vegetative growth traits of the fertilized plants with various significant differences compared to control plants in the two seasons. Among the sole treatments, SBG at 3 ml/l treatment was the superior, whereas the same fertilizer and K-A one at 1 ml/l for each were the inferior. On the other hand, combined treatments induced a more improvement in all vegetative growth parameters than the individual ones, but the prevalence in both seasons was for SBG at 3 ml/l + K-A at 1 ml/l combined one, which gave the highest records at all. A similar trend was also observed as well regarding the leaf content of chlorophyll a, b, carotenoids, N, P, K, Ca and total soluble sugars except for 1 ml/l KA treatment which gave the highest content of Ca among the sole treatments, and the increment in total soluble sugars content was attained by the individual fertilization treatments as was not significant relative to control in both seasons. In addition, the total indole content was significantly increased in response to the different treatments used in this study to reach the maximum by the two combined treatments. The opposite was the right concerning the content of total phenols. Accordingly, it can be advised to spray the herb of seashore paspalum turf with a combination of super blue-green liquid fertilizer at 3 m/l plus Kalsin-A at 1 ml/l, five times with one month interval to obtain the best growth, coverage and colour.

A trial was carried out at the Experimental Farm of Hort. Res. Inst., ARC, Giza, Egypt during 2013 and 2014 seasons to study the effect of individual application of EM biostimulant solution at 25 ml/l, NPK complete chemical fertilizer (20:20:20 + microelements) at the rates of 0, 2.5, 5.0, 7.5 and 10.0 g/bag and their combinations on growth and chemical composition of 2-years – old offshoots of date palm (Phoenix dactylifera L.) cv. Siwi planted in 50- cm-diameter plastic bags filled with about 35 kg of a mixture of sand and clay (2 : 1, v/v) under the full sun. The results showed that all fertilization treatments used in this study markedly improved all vegetative growth characters with various significant levels when compared to control in both seasons. The results indicated also that EM solution alone gave means closely near to those gained by NPK complete fertilizer at 5 g/bag with few exceptions in the two seasons. Moreover, increasing application rate of NPK fertilizer to 7.5 g/bag or more did not cause a pronounced increment in growth, but combining between EM treatment and NPK fertilizer at any rate did so, with the superiority of combining between 25 ml/l EM and 5 g NPK/bag, as this combination gave the highest means over all sole and other combined treatments in both seasons. Similar observations were also attained concerning the leaf let content of N, P, K, total indoles, chlorophylls a and b and carotenoids. Hence, it can be recommended to treat the 2-years-old offshoots of date palm cv. Siwi cultivated in 50-cm-diameter plastic bags with EM solution at 25 ml/l and NPK complete fertilizer at 5 g/bag to improve growth and quality of such offshoots before transferring to the permanent field.

This study was conducted in Department of Medicinaland Aromatic Plants, Horticultural Research Institute, ARC, Dokki, intwo successive seasons of 2012 and 2013 on Moringa oleifera plant in4 (four) different regions in the Upper Egypt (A1 and A2) and Delta(A3 and A4). It aimed to study the effect of different environments onchemicals and food ingredients, as well as determine the adaptation todifferent environments to identify the best region for growth. Theseeds were germinated in the greenhouse of National Gene Bank, andthen seedlings were transferred into (A1, A2, A3 and A4 regions) inplots with 20 × 30 m distance with 2 m distance between the plant and3 m distance between rows. Samples were taken in different growthstages (2, 4, 6, 8, 10 and 12 month).The obtained results showed that there were significant differencesin chemical components in the whole regions under study. The region(A1) showed the best values in respect to acid ascorbic (vitamin C),beta carotene (vitamin A), thiamine (vitamin B1), riboflavin (vitaminB2), niacin (vitamin B3), and tocopherols (vitamin E), calcium, iron,protein, zinc and phosphorus at a rate value higher than the region (A2)by 2%, region (A3) by 15% and region (A4) by 8%. The obtainedresults explained that the differences among regions in chemical andfood components during plant growth. The best results were obtainedfrom the Upper Egypt under study in respect to the quantity ofnutrition in addition to region (A4) which were good for cultivating ofMoringa tree in Egypt.

A study was consummated in the open field at the Experimental Farm of Hort. Res. Inst., ARC, Giza, Egypt during 2013 and 2014 seasons to explore the response of seashore paspalum (Paspalum vaginatum Swartz) turf plants cultivated in 40-cm-diameter plastic pots filled with about 6 kg of sand and clay mixture (1:1, v/v) to some fertilization treatments, viz., the humic acid liquid fertilizer at 20 ml/l, as well as diatomite powder and the commercial complete fertilizer (NPK + micronutrients) at 1 g/l for each, and also to the combined treatments between 20 ml/l humic acid and one of the abovenamed products at 1 g/l for each, when applied with irrigation water (fertigation), five times with one month interval. The obtained results showed that all individual fertigation treatments significantly improved means of all vegetative growth traits over control ones in the two seasons, but the highest means were attained by humic acid, moringa leaf powder and the commercial complete fertilizer treatments which gave averages closely near together with non-significant differences among themselves in most cases of the two seasons. However, the least improvement was found due to the sole application of diatomite powder at 1 g/l. On the other side, the combining between humic acid (20 ml/l) and any one of the other fertilizers (at 1 g/l for each) induced an additional improvement in all growth characters, with the prevalence of the connecting between humic acid at 20 ml/l and moringa leaf powder at 1 g/l, as such combination resulted the tallest plants, the highest No. plants/pot, the best coverage and the heaviest fresh and dry weights in most instances of both seasons. A similar trend was also observed as well regarding the content of chlorophyll a, b, carotenoids, N, P, K, total soluble sugars and total indoles. The opposite was the right concerning total phenols content, which was slightly affected by the most of individual and combined treatments applied in this study, except for 1 g/l complete fertilizer treatment, alone or in combination with 20 ml/l humic acid one that elevated such component to the maximum values in the two seasons, as well as the combination of humic acid at 20 ml/l + moringa leaf powder at 1 g/l that gave a contrary trend by reducing content of this constituent to the minimum values in both seasons. So, it is advised to fertigate seashore paspalum turf grown in sand and clay mixture (1:1, v/v) with humic acid liquid fertilizer at 20 ml/l plus moringa leaf powder at 1 g/l, five times with one month interval to get the best growth performance, density, colour and quality

An experiment was established under plastic house at the nursery of Hort. Res. Inst., ARC, Giza, Egypt during 2012 and 2013 seasons to find out the effect of foliar spraying with active dry yeast solution at 0, 1, 3 and 5 g/l, soil drenching with NPK mixture (2:2:1) at 2 g/pot and the interaction between each level of yeast and that of NPK mixture on growth and chemical composition of 3- months-old transplants of Peperomia obtusifolia (L.) A. Diter. grown in 14-cm-diameter plastic pots filled with about 1 kg of an equal mixture of washed sand, clay and peatmoss (1:1:1, by volume.) The obtained results indicated that various single and combined treatments improved all vegetative and root growth parameters with various significant differences compared to the control in both seasons. Active dry yeast alone at 3 g/l treatment gave better result than the other individual ones, whereas comparing between any level of dry yeast combined with NPK (2 g/pot) was more effective in improving vegetative and root growth of plants than all the individual treatments, the interaction between 3 g/l active dry yeast and 2 g/pot NPK recorded the best growth at all in both seasons. On the same line were those results of pigments content in the leaves reached maximum by 3 g/l dry yeast, but the opposite was right regarding the percentages of total soluble sugars, N, P and K content those reached the highest values by the level of 5 g/l dry yeast in most cases of both seasons. However, content of those constituents was doubled by connecting between active dry yeast at any level and NPK mixture 2 g/pot, with the prevalence of 3 g/l active dry yeast plus 2 g/pot NPK combination, that gave the highest content in the two seasons. Hence, it can be recommended to fertilize Peperomia obtusifolia cv. Variegata plants cultivated in 14-cm-diameter plastic pots with active dry yeast at 3 g/l (as a foliar spray) plus NPK mixture (2:2:1) at 2 g/pot (as a soil drench), 5 times with one month interval to obtain the best vegetative growth and high pot plant quality

A pot experiment was carried out under the full sun atOrman Botanic Garden, Hort. Res. Inst., Giza, Egypt during 2013 and2014 seasons in order to reveal the effect of different media, namely:pure sand, pure loam and sand + loam mixture at 1:1, 1:2 and 2:1 ratiosalinized with a homogenous salt mixture of NaCl and CaCl2 (1:1,w/w) at 0.00, 0.75, 1.5 and 3.0% concentrations on growth andchemical composition of the 6-months-old transplants ofMediterranean saltbush (Atriplex halimus L.) cultivated in 40-cmdiameterclay pots filled with a known weight of the abovenamedmedia.The results of this experiment have shown that all vegetative androot growth measurements were significantly improved by the law andmedium levels of salinity (0.75 and 1.5%, respectively), with themastery of 0.75% level which gave the highest means various growthtraits except of leaf area character that reached the maximum values by1.5% level over control and other salinity treatments in the twoseasons. However, 3.0% rate significantly reduced means of thedifferent vegetative and root growth parameters to the least valuescompared to control in most cases of both seasons. The mixture ofsand + loam, especially at 1:2 and 2:1 ratio recorded the bestimprovement in vegetative and root growth parameters over all othermedia in the two seasons. The interaction between the 3 used mixturessalinized with 0.75% of salt mixture gave the tallest plants, thickeststems and highest No. branches and leaves/plant in both seasons, whilethe heaviest fresh and dry weights of aerial parts and roots wereachieved by 0.75% salinity level for plants cultivated in either puresand or pure loam, or in the mixture of both at equal parts (1:1). Thecontent of chlorophyll a, b and carotenoids was slightly improved byeither soil salinity treatments or media contained loam granulars. Onthe other side, the content of Na, Ca, Cl and free proline wasprogressively increased with raising salinity level, but the opposite wasthe right concerning K content, which descendingly decreased withincreasing salinity rate. The content of Na and Cl was not markedlyaffect by medium type, whereas content of K, Ca and free proline wasgreatly increased in the leaves of plants cultivated in pure loam or puresand amended with loam at any ratio. The interaction treatments haveshown variable effects, as the highest content of Na and K was mostlyachieved by the low (0.75%) and medium (1.5%) salinity treatmentsunder loam or sand or sand + loam media, while the highest content ofCa, Cl and proline was scored by plants cultured in loam or sand +loam media salinized with the high salinity rate (3.0%). It appears from the previous results that Mediterranean saltbush(Atriplex halimus L.) plants can grow well in the loam or sandamended with loam media salinized with NaCl + CaCl2 salt mixture(1:1, w/w) at low and medium concentrations.

This investigation was conducted under open field conditions at the Experimental Farm of Hort. Res. Inst., ARC, Giza, Egypt during 2013 and 2014 seasons to find out the response of seashore paspalum (Paspalum vaginatum Swartz) grown in 40-cmdiameter plastic pots filled with about 6 kg of an equal mixture of sand and clay (1:1, v/v) to some natural activators, viz. super blue green (SBG) at 3 ml/l, Ascobien at 1 g/l, BioHorm at 1 ml/l and to some combinations of them when applied as a foliar spray, five times with one month interval. The verdure of control plants was sprayed with the tap water. The results of such investigation have shown that all vegetative growth traits were significantly improved over control in response to either sole or combined treatments applied in this study. Among the individual treatments, BioHorm at 1 ml/l was the best treatment, followed by SBG at 3 ml/l and then 1 ml/l of Ascobien treatment. An excessive improvement was obtained when combining the single treatments, especially combining between the three used activators (SBG at 3 ml/l + Ascobien at 1 g/l + BioHorm at 1 ml/l), as such combination gave the utmost high means of vegetative growth parameters at all in the two seasons. A similar trend to that of vegetative growth was also observed as well regarding the content of chlorophyll a, b, carotenoids, N, P, K, total soluble sugars and total indoles in the leaves, but the opposite was the right concerning total phenols content which was decreased by the various used treatments to reach the minimum values by the combination of 3 ml/l SBG + 1 g/l Ascobien + 1 ml/l BioHorm in the two seasons. Hence, it is recommended to spray the verdure of seashore paspalum turf with a combination of SBG (3 ml/l) + Ascobien (1 g/l) + BioHorm (1 ml/l), five times with 1 month interval during the growth stage to score the best growth performance and highest quality.
