Effect of Organic, Bio Fertilization and Foliar Spraying Treatments on Artichoke
Two field experiments were carried out at a private Farm in El-Madany Village, Abo El-Matamir Region, El-Behira Governorate, Egypt, during seasons of 2014/2015 and 2015/2016 in order to determine the influence of organic, biological fertilization and foliar spraying treatments in addition their interactions on growth, yield and yield attributes and chemical composition of artichoke Balady cultivar. The experiment was carried out in a strip-split plot design with four replications. The vertical-plots were allocated to organic fertilization treatments i.e. farmyard manure "FYM" (30 m3 per fed) and chicken manure (20 m3 per fed). The horizontal-plots were included biological fertilization treatments i.e. without biological fertilization (control treatment), treated soil with Mycorrhiza at the rate of 1 L/20 L water and Phosphorin (as a source of phosphorus) at the rate of 450 g/fed. The sub-plots were faithful to treatments of foliar spraying i.e. without (control treatment), yeast extract (100 ml/liter water), algae (1.0 g/liter water) and humic acid "HA" (1.5 ml/liter water). The obtained results could be summarized as follows:Artichoke plants which fertilized with chicken manure (20 m3 per fed) recorded the highest values of all studied characters, with exception nitrate content in receptacles in both seasons. Biological fertilizing soil with Mycorrhiza at the rate of 1 L/20 L water gave highest values of every studied traits, except nitrate content in artichoke receptacles in both seasons. Foliar spraying artichoke plants with HA (1.5 ml/liter water) exceeded other spraying treatments and gave maximum values of all studied traits, except nitrate content in receptacles in both seasons.It can be concluded that when added to soil organic fertilizer as chicken manure (20 m3 per fed) and treated soil with Mycorrhiza at the rate of 1 L/20 L water in addition to foliar spraying three times after 60, 75 and 90 days from planting date with HA (1.5 ml/liter water) in order to obtain high productivity and chemical composition of artichoke Balady cultivar under the environmental conditions of Abo El-Matamir Region, El-Behira Governorate, Egypt.

Use of Natural Raw Material Mixture and Natural Raw Potassium as Substitute for Chemical Fertilizers in Feeding Washington Navel Orange Trees under Kafr El Sheikh Conditions.
This study was done in a private orchard at Kafr El-Sheikh governorate, Egypt, during 2012 and 2013 seasons on 18 years old Washington navel orange trees on sour orange rootstock, to study the effect of fertilization with natural raw material mixture and natural raw material of potassium (feldspar) on growth, leaf NPK contents and productivity of trees. Results show that, natural raw material mixture and natural raw material of potassium (feldspar) applications significantly increased growth and leaf NPK contents as compared to regular mineral fertilizers. Moreover, natural raw material mixture and natural raw material of potassium (feldspar) treatments increased yield and improved fruit quality in terms of fruit weight, fruit size, juice size, TSS, acidity, TSS/acid ratio and vitamin C. The application of 4 kg natural raw material mixture/tree + 3 kg/tree natural raw material of potassium (feldspar) +50 kg (MOM) is considered favorable treatment, which gave the best leaf NPK contents , growth, high yield and improving fruit quality of Washington navel orange trees. This treatment is a good substitute for using chemical fertilizers to avoid their deleterious effects on soil, water and human health.

Effect of Nano Chitosan on Growth, Physiological and Biochemical Parameters of Phaseolus vulgaris under Salt Stress
Salt stress is one of the abiotic stresses; it is a major factor which reduces crop productivity. Nano particles have become a pioneer material in agriculture research nowadays because they have unique physicochemical properties. This study aimed to investigate the effects of chitosan nanoparticles on germination and seedling growth parameters under salt stress condition for bean plant (Phaseolus vulgaris L). Moreover the effect of nano chitosan combined with selected concentration of salinity (100mM NaCl) on germination and vegetative growth was also examined. Different concentrations of salinity (50 mM, 100 mM and 150 mM NaCl) was used. Data indicated that salinity decreased salt tolerance index S.T.I of germination percentage as well as seedling growth. The bad effect was higher in 150 mM concentration; so the second experiment was continued with the 100 mM NaCl concentration. The treatment of bean plantwith 100 mM of salt combined with different concentration of nano chitosan (0.1%, 0.2% and 0.3%) indicated that nano chitosan in all concentrations significantly promoted seed germination and radical length under salt stress. The best treatment on germination was 0.3 % of nano chitosan. Growth variables (plant height, leaf area, fresh and dry weights of the shoot and root) were increased significantly. High significant increase in both M.S.I and Chl.a, similarly , catalase , proline, RWC, Chl.b , caroteniods and antioxident enzymes showed positive eefect at 0.1% concentrarion.

Effect of Pinching and Spraying of Paclobutrazol on Vegetative Growth, Flowering and Chemical Composition of Zinnia elegans, Jacq.
This investigation was carried out in the Experimental Farm of Sakha Horticulture Research Station, Kafr El- Sheikh, during two successive seasons of 2014 and 2015 to investigate the effect of pinching and foliar spray of paclobutrazol (PBZ) at 0, 50, 100 and 150 ppm as well as interaction with them on growth, flowering and chemical composition of Zinnia elegans as pot plant. The obtained results revealed that the pinching increased stem diameter, number of branches and flowers/plant, fresh and dry weights of vegetative parts and flowers/plant, and N, P and K percentages but decreased plant height, leaf area, flower diameter as well as chlorophyll a, b and (a+b) contents. PBZ treatments caused an increase in the stem diameter, number of branches and flowers/plant, chlorophyll a, b and (a+b) as well as P and K percentages, while decreased plant height, fresh and dry weight of vegetative parts and flowers/plant and flower diameter. Concerning the interaction, shortest plant height, the largest number of branches and flowers/plant and the highest amount of chlorophyll content were obtained with pinching and 150 ppm PBZ treatment. It may be concluded that the pinching and treated with PBZ at 100 or 150 ppm gave a good feature for potted Zinnia elegans plants.

Effect of Plant Population and Distribution and Nitrogen Levels on Yield and Quality of Sugar Beet
Two series field experiments were done for the period of 2014/2015 and 2015/2016 seasons at Abo-SaiedVillage, KafrEl-SheikhCenter, Kafr El-Sheikh Governorate to study the effect of plant population and distribution and nitrogen levels on yield and quality of sugar beet, "CV. Zwan Poly". The studied plant distributions were 25, 30 and 35 cm on both sides of terrace (Mastaba) 80 cm width and 20, 24 and 28 cm on both sides of terrace (Mastaba) 100 cm width, which resulted in three plant populations of 30000, 35000 and 42000 plants/fad. The used design was split-plot with 4 replicates. Results showed that plant population and distribution had significant effects on all studied traits. Cultivating beet seeds at 35 cm distance between hills on both sides of mastaba 80 cm width (30000 plants/fad) resulting significant increases in number of leaves/plant, foliage fresh weight/plant, plant weight, root weight as well as sucrose percentage, total soluble solids(TSS) and purity percentages. Increasing N-levels from 69 to 92 and 115 kg N/fad significantly increased root weight, root diameter, root length, number of leaves, foliage fresh weight/ plant and plant weight in both years, while it significantly decreased sucrose, TSS and purity percentages in both years. Generally, it could be accomplished that cultivating sugar beet on both sides of mastaba 80 cm width and 25 cm between hills and fertilizing plants with 115.0 kg N/fad could be recommended for maximizing root yield under the ecological circumstances of this research.

Callus Formation and Shoot Regeneration as Affected by Plant Growth Regulators and Explant Types in Three Strawberry Cultivars (Fragaria x ananassa Duch.).
An experiment was undertaken to find the most appropriate explant type, (i.e., shoot tip, leaf, immature fruit and anther explants) and the appropriate growth regulator concentrations and combinations on callus formation and shoot regeneration in 3 strawberry (Fragaria x ananassa Duch.) cultivars, namely Festival, Fortuna and Sweet Charlie. As for callus formation in response to growth regulators, ten combinations between 2, 4-dichlorophenoxyacetic acid (2, 4-D) and 6-Benzylaminopurine (BAP) were used. significant variances among different media were obtained and 0.5mg L-1 BAP +1.5 mg L-1 2, 4-D produced the highest response (95.75%) in comparison to other media. Maximum callus formation percentage was obtained the using runner explant (75.38%) while immature fruit explant gave the lowest value. Festival and Fortuna cultivars recorded higher percentage of callus formation than Sweet Charlie. Calli derived from the good callus induction medium were tested for shoot regeneration with ten different combinations from BAP and NAA. The results exhibited that using runner as explant source and 2.0 mg L-1 BAP with the three tested cultivars recorded significant regeneration percentage in comparison to other combinations.

Yield, Quality and Stability Evaluation of Some Sugar beet Varieties in Relation to Locations and Sowing dates
Two separate field experiments were carried out in two sowing dates at each of El-Nubaria (latitude of 300 37\ N and longitude of 420 07\ E, and elevation of 34 m above sea level), El-Buhira Governorate and Tamia (latitude of 290 18\ N and longitude of 300 25\ E and elevation of -13 m beyond sea level), El-Fayoum Governorate, Egypt in 2013/2014 and 2014/2015 seasons to evaluate eight sugar beet varieties for its performance for economic characteristics and stability. The sugar beet varieties were; Cesira, Univeres, Esperanza and Yaman as monogerm seeds as well as Carola, Oscar poly, Panther and Farida as multigerm seeds, and sowing dates were; the 1st week of both October and November in the first and second seasons respectively. Every experiment of location was carried out in strip-plot design with three replications. A stability analysis was done to test the varieties to find out the most stable one over the eight environments under this study. The obtain results show that growing sugar beet at Tamia site resulted in highest values of root fresh weight/plant, root yield/fed as well as the percentages of sucrose, corrected sugar and quality index, while, at El-Nubaria, the highest value of corrected sugar yield/fed was obtained.Sugar beet planted on October had the higher values of root fresh weigh/plant, root and sugar yields/fed, as well as the percentages of sucrose, corrected sugar and quality index and less significant impurities compared with that sown on November.Oscar poly variety significantly surpassed of root fresh weigh/plant and root yield/fed, while Cesira variety surpassed of corrected sugar yield, sucrose%, corrected sugar% and quality index%. Farida had thelowest response for potassium at El-Nubaria, while Panther had the lowest for Na at El-Fayoum. Oscar poly was significantly higher in root fresh weigh/plant, and root and sugar yields/fed in October planting. Under this work, it could be recommended that Oscar poly, Panther and Farida varieties were the most high and stable root yield-type. Meanwhile, Cesira, Univeres and Carola were the most suitable ones for sucrose% and sugar yield-type and were useful for beet sugar manufacture earlier in the crushing season.

Increased Resistance to Salt Stress of Duranta plumieri Irrigated with Seawater by Using Thiamin, Humic Acid and Salicylic acid.
Global climatic changes limited the fresh water supply, which led to increasing the need for irrigation water. For this reason, the main objective of this study was to investigate the role of humic acid (HA), salicylic acid (SA) and thiamin (Vitamin B1) in increasing the Duranta plumeri resistance to irrigate with diluted seawater. The experiment was conducted on Duranta plumieri, (synonym to Duranta erecta L.) during the two successive seasons of 2014 and 2015 to estimate the effects of soil application with humic acid at 1000 and 2000ppm concentrations and foliar spraying plants with salicylic acid or thiamin at 250 and 500ppm combined with irrigation with diluted seawater at three concentrations: 2000, 4000 and 6000ppm on vegetative growth and associated with physiological parameters. The results revealed that the plant vegetative growth parameters were considerably affected by salinity stress. Plant height, the number of branches/plant and shoot fresh and dry weight were linearly decreased with the increasing in saline water concentration. Also, salt stress was negatively affected the total carbohydrate contents, photosynthetic pigments, reducing and non-reducing sugars and mineral uptake ( N,P,K and Mg) as well as higher contents of Na+ and Cl- elements. In contrast to this, SA, B1 or humic acid were induced a stimulatory effect on the all vegetative growth parameters in plants which irrigated with all diluted seawater concentrations. The highest values of vegetative parameters and total chlorophylls were obtained with humic acid at 1000 and 2000ppm concentrations under all salinity concentrations. SA enhanced the physiological processes in Duranta plants under saline conditions through increasing significantly the total carbohydrate and carotenoids contents, and reducing and non-reducing sugars. The exogenous application of thiamin significantly increased proline content in salinity stressed plants. The greatest contents of N,P,K and Mg in plants under salinity stress were obtained with soil application of humic acid followed them with the treatment of spraying with SA and B1. Also, these treatments led to decrease the contents of Na+ and Cl-. It could be recommended that soil application with humic acid at 2000ppm can ameliorate the negative effects of irrigation with diluted seawater up to 6000ppm salinity concentration and spraying Duranta plants with SA or B1 at 500ppm increased the growth and physiological processes under 4000ppm salinity.

Estimation of Heterosis, Combining Ability and Some Genetic Parameters in Sweet Pepper
Four pure lines of pepper developing locally namely (S-1004, L-1008, K-1017 and E-1001) were used in a full diallel crossing program to evaluate the performance of those parents and their crosses, to estimate combining ability and genetic parameters for agronomic, fruit yield and its components traits. Crosses among parents were carried out in plastic house in fall season of 2012 using full diallel cross mating to produce 16 hybrids the parents, F1s and reciprocals hybrids plus hybrid check were sown in plastic house in fall season of 2013 using a R C B D design with four replicates. Data were recorded for plant height, branches number per plant, fruit number per plant, fruit diameter, fruit weight, fruit length and fruit yield per plant. The obtained results showed significant differences among the different genotypes for all traits under investigation. The hybrid (1×4) and the reciprocal hybrid (4×2) produced higher fruit number (73.90, 63.40) and fruit yield per plant (4.06, 3.28 Kg) while, the hybrid (1×3) and reciprocal hybrid (3×2) gave higher fruit length 8.02 cm. Positive and negative heterosis were found among the F1,s and reciprocals. The hybrid (1×4) and reciprocal (4×2) produced higher heterosis in fruit number (88.85, 62.02%) and fruit yield per plant (79.64, 53.99%) respectively. Significant differences were revealed in general and specific combining abilities for all studied traits. Suggesting the presence of both additive and Non-additive gene effects in the inheritance of the various studied traits. The ratio of σ²gca to σ²sca was less than unity for all studied traits, expect for fruit weight, which showed pre dominant role of non-additive gene action in the inheritance. Estimates of GCA effects showed that the best combiner parents were found to these of P1 for plant height, fruit diameter and fruit weight, while P4 for branches number, fruit number, and for fruit yield per plant, and P2 for plant height and P3 for fruit length. Estimates of SCA effects showed that the hybrid 1×2 reflected the highest value in fruit diameter (0.56) and fruit weight (1.35) and the hybrid 1×4 in fruit number (10.02) and fruit yield per plant (0.54) and 2×3 in branches number per plant (0.81) and fruit weight (1.21), and 3×4 in plant height (19.30) and fruit length (0.38). Estimates of RCA effects showed that the reciprocal hybrid 3×1 was the best for fruit weight (8.09), while the reciprocal hybrid 4×1 was the best for branches number per plant (1), fruit number (16.13), fruit length (0.55) and for fruit yield per plant (0.91) whereas 3×2 was the best for plant height branches number per plants (5.37) and fruit diameter, and 4×3 was the best for fruit number (6.03) and for fruit diameter (0.30). The values of σ² D and σ² D_r were more than that (σ² A) for all studied traits expect for fruit weight and fruit yield per plant, which were less than those for fruit diameter, fruit weight and fruit yield per plant, and this reflects the exceeded one for the value of average dominance degree for all studied traits in both diallel and reciprocal crosses expect for fruit diameter in reciprocal crosses which was less than one. As for broad sense heritability it was high for all studied traits in both diallel and reciprocal crosses, while, the values narrow of sense heritability were low in diallel and reciprocal crosses for all studied traits except for fruit weight, and fruit diameter were high value in reciprocal crosses (0.81) and (0.52) respectively. It was concluded that two inbred (p1 and p4) could be used in a breeding program to develop new versions of high fruit yield per plant and high SCA to produce better fruit yield hybrids and most studied traits were under over dominance gene action. This showed that developing elite hybrids, and most studied traits were under over dominance gene action. This showed that developing elite hybrids were the best method for improving pepper fruit yield per plant in pepper plant.

Micropropagation of Oregano (Origanum syriacum L.) Through Tissue Culture Technique
This research was carried out at the Plant Tissue Culture Laboratory (PTCL) in Faculty of Environmental Agricultural Sciences, Arish University, Egypt during 2013 to 2016. The aim of this study was using tissue culture technique for the micropropagation of Origanum syriacum L. plant. One node cutting and shoot tip were cultured on Murashige and Skoog (MS), Nitsch and Nitsch (NN) and Gamborg (B5) media. The results showed that shoot tip cultured on the MS medium had the best combination for the establishment stage of mother plants. Shoots cultured on MS medium supplemented with0.50 mgl-1 Kin and 0.05 mgl-1NAA produced the highest shoots developed during multiplication stage. MS medium supplemented with 0.40 mgl-1 thiamine achieved the best shoots development compared with the other additive treatments and control. Addition of 1 mgl-1IBA to the full strength MS medium and 1.00 mgl-1 IAA to the half strength MS had the highest number of main roots and root lengths. Hardening the produced rooted plantlets were done in a greenhouse in pots containing mixture of peatmoss, vermiculite and washed sand at the rate (1:1:1) and after adjustment of mixture pH. Plantlets were successfully acclimated with 93 % survive.

Evaluation of Seed Germinability and Field Emergence Of Some Maize (Zea mays, L.) Hybrids Under Salinity Stress Conditions
Laboratory and field emergence under greenhouse experiments were designed to evaluate the germinability and field emergence of eight maize hybrids, i.e.; maize hybrids single white (Pioneer 30K8, Giza 130 and Hi Tech 2031), maize hybrid single yellow (Hi Tech 2066), maize hybrids triple white (Giza 310, Giza 321 and Giza 324) and maize hybrid triple yellow (Giza 352) under some levels of salt concentrations induced by sodium hypochlorite NaCl 1% solution, i.e.; (Tap water 320, 1000, 2000, 3000 and 4000 ppm) during 2015 season. The best results of maize hybrids were obtained by Hi Tech 2031 and the depressed values restricted by Giza 352 and Giza 130, respecting of germination indices i.e. G (%), mean germination time (MGT), germination velocity index (GVI), seedling vigor index (SVI); seedling growth indices i.e. plumule length (cm), radical length (cm), seedling fresh and dry weights (g); salinity stress assay i.e. germination stress index (GSI), seedling length stress tolerance index (SLSI), radical length stress tolerance index (RLSI) and proline content; and field emergence. Results also indicated that, all salinity stress levels while compared with control treatment (320 ppm) recorded the lowest values of all previous studied traits and the lowest values were obtained by NaCl level (4000 ppm) . Regarding to the interaction, all maize hybrids under control treatment (320 ppm) recorded the highest values of all traits compared with all salinity stress levels. The best values recorded by Hi Tech 2031, Pioneer 30K8, Hi Tech 2066, Giza 310 and Giza 321 respectively. Giza 352 and Giza 130 recorded the lowest values under all NaCl concentration levels. There were highly significant differences between studied hybrids and salinity treatments and the mean performance for studied characters was discussed.

Effect of Bio-Fertilizers, Plants Extracts and Active Dry Yeast on Marjoram Plants.
This experiment was carried out to study the effect of bio fertilizers, active dry yeast and garlic extract on growth characteristics, essential oil determination and chemical composition of marjoram (Majorana hortensis L.) at private farm, Seif El Din Village, Zarqa City, Damietta Governorate, during 2012 and 2013 seasons. The experiment was set up using a split-plot design with 3 replications. The main-plot included the three biofertilizers (0.0, Biogene and Biogene plus Phosphorene), whereas, the sub-plots were devoted for active dry yeast and Allium sativum extract. The final statistical analysis indicated that the highest values of herb (fresh and dry), essential oil percentage and oil content / plant, as well as the chemical constituents of Majorana hortensis plant were produced when Biogene plus Phosphorene were combined with active dry Allium sativum or garlic extract treatments.
