Indirect Micropropagation of Gerbera jamesonii Bolus cv. Winter Queen through Callus Redifferentiation
This research was achieved in the Laboratory of Plant Tissue Culture, Vegetable and Floriculture Department, Mansoura University, Egypt during 2015/2016 on Gerbera jamesonii Bolus cv. Winter Queen for studying the indirect micropropagation of this important pot and cut flower plant in Egypt. For callus induction, unopened flower buds(10 days old) were cultured after preparation on MS medium fortified with either 2,4-D or NAA (0.5, 1.0, 2.0, 4.0 and 6.0 mg/l) each alone. The calli were transferred on media supplemented with either BAP or meta-topolin (0.0, 0.3, 0.6, 1.2 and 2.4 mg/l) each alone with 0.5 mg/l NAA as a fixed concentration for redifferentiation. Moreover, shoots were transferred to media supplemented with NAA (0.0, 0.5, 1.0, 1.5 and 2.0 mg/l) with 0.3 mg/l meta-topolin for the in vitro rooting. Results showed that 6.0 mg/l 2,4-D produced the heaviest callus fresh weight (7.22 g), and decreased the callus induction time (17.50 days), but the callus texture was compact and creamish to brown in color. In addition, the lower concentrations from either 2,4-D (1.0 and 2.0 mg/l) or NAA (0.5 to 1.0 mg/l) produced a nodular greenish calli with greenish color. Also, supplying the redifferentiation media with 1.2 and 2.4 mg/l meta-topolin or 2.4 mg/l BAP, significantly reduced the redifferentiation time, increased the multiplication percentage and micro-shoots number. Moreover, ½ strength MS medium fortified with 2.0 mg/l NAA+0.3 mg/l meta-topolin gave the maximum roots number, rooting% and reduced the roots initiation time. Finally, well rooted plantlets were transferred to a mixture of peatmoss+perlite+clay (2:1:1 v/v) produced a survival percentage of 92.90% with a plantlets height of 4.61cm and 4.50 leaves / plantlet on average.

Landscape Studies of Maintenance of Lawns in some Football Yards at Dakahlia Governorate Part 1. Effect of Different Fertilization Programs on the Growth Characteristics and Chemical Composition of Turfgrasses of Five Established Football Fields.
This study was carried out during the two successive seasons of 2013/2014 and 2014/2015 on five established football (soccer) green fields (yards) in the urban and suburban areas of MansouraCity, Dkahlia Governorate, Egypt. It aimed to compare the effects of different fertilization programs on the performance and quality of the lawn (turfgrass) of the five yards (fields). Five football fields were chosen based on similarity of basic specifications namely; a standard field size (65-70 m in width and 100-110 m in length), planted using sods of Paspalum vaginatum Sw lawn (turfgrass), sandy soil (sand thickness of 15-20 cm over 30 cm layer of pebble stones), all have existing drainage systems, and no soil aeration were carried out in any of the fields' maintenance programs. The football yards (fields) were Mansoura Stadium, MansouraUniversity and El-Shaab stadiums (located in Mansoura city) in addition to Beny Ebeid and Secondary Beny Ebeid stadiums (located in Beny Ebeid town). Data of maintenance programs were collected from the maintenance managers of different stadiums. In addition, measurements for the visual color and quality in addition to total chlorophyll contents (mg/g fresh clipping sample), and N, P and K percentages in the clipping samples of the turfgrass (lawn) of the five fields were carried out during the two seasons.The obtained results showed that increasing number of N applications (doses) combined with reasonable low quantity each application (dose) had a positive effect on color and quality of the turf in addition to its chlorophyll content. The results also supported the need of adding phosphorus to the turfgrass, but to a much lesser degree than the need of nitrogen. Based on the results of both seasons, Mansoura University Stadium fertilization program was the best to achieve better visual color and quality of the turfgrass in addition to total chlorophyll contents (mg/g fresh weight) of the clippings. This program comprised of five applications (doses) of a mixture of urea and potassium nitrate fertilizers (50% each); each dose containing 0.62 Kg N /100 m2 of the grass field during spring and summer months (March – October); summing up a total of 3.12 Kg N / 100 m2 / year, in addition to two applications of calcium super phosphate ; each containing 0.34 Kg P /100 m2 of the grass field during fall and winter months (November – February) summing up a total of 0.69 Kg P / 100 m2 of grass.

Effect of Irrigation Systems and Calcium on Productivity and Quality of Peanut (Arachis hypogaea L.) at New Valley
Two field experiments were carried out at Desert Research Center (D.R.C.), Agricultural Experiment Station (27°47.7 42 N, 30°24.7 63 E), EL-Kharga Oasis, New Valley Governorate during the two growing seasons of 2016 and 2017 to study the effect of irrigation systems (surface, advanced surface, drib and sprinkler irrigation) and calcium foliar application levels (0, 2, 4 and 6 cm3 Ca/ L) on productivity and quality of peanut (Arachis hypogaea L.) under New Valley conditions. Results showed that the effect of irrigation systems on all studied parameters were significant. The lowest values of number of pods plant-1, pods weight plant-1, 100 seed weight, pods yield and seed yield were obtained when surface irrigation system was applied, while maximum values were when sprinkler irrigation system in both seasons. However, the difference between this irrigation system and drip irrigation was not significant in both seasons. The lowest values of harvest index (%), shelling (%), oil seed yield (kg/ fed.), water use efficiency (kg/ m3) and protein (%) were obtained when surface irrigation was used, while the highest values were obtained when drip irrigation was used in both seasons. On the hand, applying of the drip irrigation system gave the lowest values for phosphorus, calcium, zinc, manganese and iron. Maximum values of the mineral content of seed produced by using advanced surface irrigation system. However, the seed content differences between it and the application of surface irrigation system were insignificant during both seasons. Raising of calcium foliar levels up to 6 cm3Ca/ to a significant increase in all studied parameters except, oil seed yield (kg/ fed.), water use efficiency (kg/ m3), phosphorus seed content (%) and Zn seed content (mg/ kg) during both seasons. On the other hand, Mn seed content (mg/ kg) and Fe seed content (mg/ kg) had adverse trend where, maximum values had obtained with control treatment and there was a gradual decrease as concentration of calcium spray application in both seasons. Maximum values of these parameters were produced by 6 cm3Ca/ L foliar application in both seasons as compared with (control). However, the difference between spraying with this concentration and spraying with the lowest concentration (4 cm3Ca/ L) was not significant with all the studied traits during both seasons. The interaction between irrigation systems and calcium foliar application levels had a significant effect on all studied characters except, Protein (%), phosphorus seed content (%), Zn seed content (mg/ kg) and Fe seed content (mg/ kg) during both seasons. The highest values of studied traits concerning the number of pods plant-1, pods weight plant-1 (g), 100 seed weight (g), pods yield (kg/ fed.), seed yield (kg/ fed.) and oil seed yield (kg/ fed.) were obtained when sprinkler system and Ca foliar spraying at rate of 6 cm3Ca/ L was used both seasons. However, maximum values harvest index (%), shelling (%) and water use efficiency (kg/ m3) were obtained when drib irrigation system and spraying Ca at rate of 6 cm3Ca/ L was applied in both seasons. On the other hand, maximum values of Ca seed content (mg/ kg) were obtained at the irrigation by advanced surface system and spraying by the higher rate of calcium (6 cm3Ca/ L).Nevertheless, the highest values of Mn seed content (mg/ kg) were obtained at the irrigation by advanced surface system and the control treatment of calcium (without foliar) in both seasons. Therefore, the study recommends that using of sprinkler or drip irrigation system and spraying by the rate of 6 cm3Ca/ L for the cultivation of peanut under NewValley conditions.

Effect of Potassium Humate and Nitrogen Fertilization on Yield and Quality of Sugar Beet in Sandy Soil
Two field experiments were conducted at Wadi El-Natrun, El-Bahira Governorate, (latitude of 30.480 N and longitude of 30.500 E) in 2015/2016 and 2016/2017 seasons to study the effect of potassium humate and nitrogen fertilization and its impact on yield and quality of sugar beet sown in a sandy soil. The present work included twelve treatments, which were the combination of four potassium humate levels as soil additives (without, 4, 8 and 12 liter /fed) and three nitrogen rates (80, 100 and 120 kg N/fed). the treatments were arranged In strip plot design with four replicates. Potassium humate levels were occupied the vertical plots, while nitrogen rates were represented in horizontal plots. Results show that soil application of 8 and/or 12 l potassium humate/fed significantly exhibited higher values of leaf area index (LAI), root diameter, root and foliage fresh weight/plant, sucrose%, and quality index as well as extractable sugar%, root and sugar yields/fed in both seasons. Moreover, root potassium, sodium, a-amino N contents, alkalinity coefficient and sugar lost to molasses% were insignificantly affected by the studied potassium humate levels.Increasing nitrogen fertilizer from 80 up to 120 kg/fed positively enhanced LAI, root diameter, root and foliage fresh weights/plant in both seasons. Whilst, the highest sucrose, extractable sugar percentages, sugar and root yields/fed, quality index and alkalinity coefficient were obtained by the application of 100 kg N/fed. On the other hand, higher values of sugar lost to molasses% and non-sucrose components (K, Na and a-amino -N) were detected in beets fertilized with 120 kg N/fed. Based, under conditions of the present work, application of 8 1/fed potassium humate and fertilized with 100 kg N/fed could recommend obtaining the highest root and sugar yields/fed.

Yield and Technological Characteristics of Sugar Beet as Affected by Sowing Date, Nitrogen Level and Harvesting Age
In order to investigate the effect of nitrogen fertilizer levels, sowing date and harvesting age on growth yield and root quality of sugar beet. Four field experiments were conducted at Mallawi Research Station, El-Minia Governorate during 2015/2016 and 2016/2017 seasons. Sugar beet sown at two dates (the 1st of September and October) fertilized with three nitrogen levels (80, 100 and 120 kg N/fed.) and harvested at three ages (180, 195 and 210 days after sowing). The results showed that all studied traits of sugar beet were significantly affected by sowing date in both seasons. The highest values of root length, diameter, root fresh weight, as well as a-amino N, Na, K, sugar lost to molasses, root and corrected sugar yields were obtained by delaying sowing date from September 1st to October 1st. On the contrary, an higher sucrose, quality and corrected sugar percentages were detected in beets sown earlier in September. Raising nitrogen fertilization level from 80 to 100 and 120 kg N/fed. resulted in a gradual and significant increases in root fresh weight, root length and diameter, root yield, sugar lost to molasses and corrected sugar yield in both seasons. While, alkalinity coefficient and quality percentages were decreased. The highest sucrose and corrected sugar percentages were recorded by applying 100 kg N/fed. The studied traits were markedly influenced by plant age at harvesting in both seasons. Root length and diameter, root fresh weight and yield/fed, sucrose, quality, corrected sugar percentages and corrected sugar yield/fed. were increased gradually with increasing plant age at harvest from 180, 195 to 210 days, in both seasons, while Na, sugar lost to molasses and alkalinity coefficient were decreased. Under these conditions of the present work, sowing sugar beet on October 1st, with nitrogen fertilization at rate of 120 kg N/fed. and harvested at 210 days from sowing could be recommended to obtain the highest root yield/fed., while harvesting it after 195 or 210 days to get the highest sugar yield/fed.

Growth, Yield and Chemical Composition Response of some Legume Crops to Inoculation with Non-rhizobial Endophytic Bacteria from Melilotus indicus (L.) All. Nodules
Two field experiments were carried out during two successive seasons of 2015 and 2016, to study the growth response and yield as well as chemical composition of some legume plants vis., cowpea (Vigna unguiculata L. cv Kaha 1), common bean (Phaseolus vulgaris L. cv. Nebraska), peas (Pisum sativum L. cv. Master B) and fenugreek (Trigonella foenum-graecum L., cv. Giza 3) to inoculation with non-rhizobial endophytic bacteria, strains ,vis., Enterobacter sp.(strain No.1), Pseudomonas sp.(strain No.2) and Pseudomonas sp.(strain No.3 ) which were isolated from root nodules of Melilotus indicus (L.) All. Results showed that almost all treatments increased all vegetative growth parameters tested, vis., shoot minerals, nitrogen content and total carbohydrate and seeds minerals, total protein, total carbohydrate and total yield (seeds and green yield) of the four tested legumes. Further, the three bacterial strains used in this study showed high growth promoting activities. They gave high production of IAA and showed highly antagonistic activity against some phytopathogenic fungi. Therefore, the best results were obtained with treatments T2 for cowpea and fenugreek and T4 for common bean and pea. So, it could be recommended to use these bacterial strains as inoculants for cowpea, fenugreek, common bean and pea crop legumes.

Response of Barley Plants to Potassium Spraying under Water Deficit Conditions
A field experiment was carried out at the Experimental Farm of Sakha Agricultural Research Station during the winter season of 2014/2015 and 2015/2016 to study the impact of foliar application with potassium on growth, yield, its components and the economic yield as well as on irrigation water productivity of barley Giza 126 cultivar under water deficit conditions. The experiment was laid out in spilt plot design with four replications. The main plots were designated to irrigation treatments i.e. I0 = full irrigation (control), I1 = two irrigations at 35 and 70 days after sowing (DAS), and I2 = one irrigation at 35 days after sowing (DAS), while the sub plots were devoted to four treatments of foliar application with potassium (K0 = without spray, K1 = 1% K2O, K2= 2 % K2O and K3= 3% K2O) in the form of potassium sulfate (48%). Results showed that, increasing water stress significantly retard photosynthetic pigments, flag leaf area, relative water content (RWC %), yield and its components and carbohydrate content. On the other hand, plants under water stress showed marked increase in grain protein content. Foliar spraying with potassium markedly increased most growth and yield parameters and quality of barley grains. The results showed that high irrigation water productivity (IWP) is attainable without significant yield penalty (utilizing a two irrigations at 35 and 70 days after sowing (DAS), or one irrigation after 35 DAS and foliar spraying with potassium (1% K2O, or 2 % K2O, or 3 % K2O) offering chance for improving land level water use and enhancing the crop economic return.

Effect of Sowing Dates on Potential Yield and Rust Resistance of Some Wheat Cultivars
Wheat production influenced by stripe, stem and Leaf rusts all over the world and Egypt. In the preset study, effect of sowing dates (1st November, 15th November, 1st December and 15th December) on rust fungi causing agents and their impact on potential yield of nine wheat cultivars. (Giza 171, Shandaweel 1, Misr 1, Misr 2, Sakha 94, Sakha 95, Sids 12, Gemmeiza 11 and Gemmeiza 12) were evaluated during 2015/16 and 2016/17 seasons. Results showed that among sowing dates, rust severity was lower in early sowing (1st November and 15th November) and sever infection was in late sowing (1st December and 15th December). In the early sowing has paramount importance to combat rust severity effectively. Results also revealed that sowing in Nov.15 resulted in high number of days to heading, plant height, number of spikes/m2, biological yield, number of grains/spike and straw yield in both seasons. Meanwhile sowing in 1st November resulted in high values of days to maturity and 1000 kernel weight. Wheat cultivars notably differed in all previous mentioned characters. Gemmeiza 11 was early in heading while Misr 2 was delayed in both seasons. Sids 12 and Gemmeiza 11 were early in maturity while Shandaweel 1 was vice versa. Sakha 95 cultivar surpassed other cultivars in grain yield/fed followed by Misr 2. Moreover Sakha 95 expressed high rust resistance followed by Shandaweel 1 and Giza171 in both seasons. Results exhibited that rust disease severity has a strong negative correlation with grain yield and the interaction effects among sowing dates and different wheat cultivars were significant on all studied characters in both seasons. Finally, delaying sowing date caused considerable reduction in previous studied characters in both seasons and increase rust severity.

Combining Ability and Heterosis Analyses for Earliness and Yield Potential in some Bread Wheat Crosses under Optimum and Late Sowing
This study was carried out during the two successive seasons 2014/2015 and 2015/2016 at the experimental farm of Sakha Agricultural Research Station, Kafr El-Sheikh, Egypt. Eight bread wheat (Triticum aestivum L.) cultivars and lines, differing in their earliness were used as parents and evaluated with their 28 F1's under optimum (29th Nov.) and late (29th Dec) sowing dates. The studied characters were earliness, grain yield and its components. significant differences were detected between the two sowing dates and among the studied genotypes in each sowing date and across the two sowing dates. The mean squares of GCA and SCA for most studied characters were significant or heighly significant under both sowing dates. Means of the parents and their crosses were decreased under late sowing date for all the studied characters. The early parents and most of their F1's had the desirable mean values for combining ability and heterosis effects for earliness characters. Moreover, the parents Giza 171, Misr 2 and Line 1 (late parents) were the best parents for mean performance and general combining ability (GCA) for grain yield and its components in most cases. Four crosses resulting from late and early parents under both sowing dates were the highest ones and could be used in advanced studies for earliness and grain yield potential. The GCA/SCA ratios were more than unity for most studied characters under both sowing dates.

Evaluation of Antimicrobial Activities of Mycelia and Crude Extracts of some Egyptian Wild Mushrooms, Agaricus and Ganoderma Species
The current study focuses on the evaluation of the antimicrobial activities of some Egyptian wild mushrooms: two strains of Agaricus namely; Agaricus bitorquis (A40), Agaricus bisporus (A60), and three species of Ganoderma (G1, G3, G7). They were investigated against 13 pathogenic microorganisms (eight fungal spp and five bacterial spp). The mycelia of A40, G7, and G3 were the most effective on the largest number of pathogenic microorganisms. Antimicrobial activities of the crude extracts of (A40, G7, G3) by different solvents (methanol, water & ethylacetate) were examined by the agar well diffusion method. The results revealed that these mushrooms have potential activities as natural antifungal and antibacterial. The highest antagonistic effect of mushroom extracts was exhibited by ethylacetate extract of Ganoderma (G7) against F. oxysporum and Ganoderma (G3) is the most effective against Salmonella typhi. The mushroom extracts have lower antifungal and antibacterial activites comparing with antifungal except ethylacetate extracts of both Ganoderma (G3) and Agaricus bitorquis (A40) exhibited higher inhibition effect against Curvularia sp.

Effect of Salicylic Acid and Mannitol on White Cabbage Plants under Saline Conditions
An experiment was conducted in the Experimental Farm of the Desert Research Center, Ras Sudr, South Sinai Governorate to study the effects of foliar applications of salicylic acid (SA) and mannitol (M) on white cabbage Kalorama F1 cv grown under saline conditions (soil and irrigation water). White cabbage seedlings were transplanted on to soil after forty days from seed sowing. Foliar applications began 30 and 35 days after transplantation for SA and M, respectively. A total of three sprays were given at an interval of 15 days. Three different foliar applications of SA (0, 75 and 150 mg l-1) and three different M treatments (0, 2000 and 4000 mg l-1) were used, in factorial randomized completely block design. Stem length, head width, head weight, total yield, vitamin C, total sugars, chlorophyll a and b, dry weight and minerals content (N, P and K) were studied. All parameters were significantly influenced by applying different SA especially 75 mg l-1, as well as application of higher dose of M (4000 mg l-1). The highest values were observed in 75 mg SA l-1 + 4000 mg M l-1 treatment. Thus, the present results revealed that application of foliar SA and MA must be performed to overcome saline stress conditions.

Callus Iduction and Differentiation for Value Medicinal Plant (Moringa oleifera) in Response to Different Explant Types and Growth Regulators
The laboratory experiments aims to investigate the response of different explant types obtained from a very value medicinal plant, Moringa oleifera for callus induction and its plant regeneration. Four different explant types (epicotyls, stems, leaves and shoot tips) were cultured in Murashige and Skoog (MS) Medium fortified with various auxins 2,4-Dichlorophenoxyacetic acid (2,4-D) and a-naphthalene acetic acid (NAA) at different concentrations of 0.5, 1, 1.5 and 2 mg/L singly or in combinations with different cytokinins (BA and Kin) to induce callus formation. The results obtained indicated that callus can be generated from all the tested plant parts, but there were very big differences among the characters of callus induced from the different explants. Shoots tips cultured on MS medium supplemented with 2,4-D at 2.0 mg/L in combination with BA at 0.5 mg/L induced Maximum callus formation percentage of 100 % coupled with the highest callus fresh weight of 9.99 g. For Callus differentiation, callus derived from shoot tip and cultured on MS media fortified with BA at 1.5 mg/L produced 100 % callus differentiation percentage and significantly the highest value of shoots number (10.36 shoots).

Effect of Irrigation Intervals and Submergence Head on Rice Yield and Soil Quality under Salinity of Soil and Water
Two field trials were performed in 2015 and 2016 seasons at the Experimental Farm of El Sirw Agricultural Research Station, Damietta province, Egypt. The trial aims to study the effect of irrigation intervals and submergence head on growth, productivity and water use efficiency of Sakha 104 rice cultivar, as well as, soil characteristics under salinity of soil and water. Strip plot design was assigned as the experimental design with three replicates. The vertical plots were denoted for irrigation intervals namely; (3, 6 and 9 days). The horizontal plots were arranged for submergence head namely;(3 and 6 cm). Salinity levels of soil were 7.68 and 7.45 dSm-1 in the first and second seasons, respectively. Results showed that prolonging irrigation intervals markedly reduced growth characteristics such as flag leaf area, leaf area index (LAI), dry matter production, stomatal conductance, number of tillers hill-1, chlorophyll content and plant height, as well as, grain yield, yield components and total water applied. The prolonging irrigation interval significantly increased salinity levels, sodium content of soil, bulk density and decreased potassium content of soil. The submergence head of 6 cm increased all measured growth parameters, yield, yield components and enhancing soil characteristics as compared with 3 cm of submergence head except heading date and number of unfilled grains panicle-1. The irrigation interval of 3 days with submerged head of 3 cm gave the highest value of water use efficiency followed by 6 days with 6 cm. Generally, under this study and similar conditions, irrigation interval every 3 days with submergence head of 6 cm are suitable to enhance growth, productivity of sakha 104 rice cultivar and effective to improve soil quality. However, the irrigation interval of 3 days with submergence head of 3 cm are suitable to enhance water use efficiency.

Germination of Indian Almond (Terminalia arjuna Roxb.) Seeds as Affected by Soil Salinity in Presence or Absence of Magnetic Iron
The hard seed coat is the major hindrance in achieving good and uniform germination for Indian almond (Terminalia arjuna Roxb.) fruits, especially when large plantations are to be raised under soil salinity stress. The present investigation was therefore, undertaken under the full sun at the nursery of Orman Botanical Garden, Giza during 2016 and 2017 seasons with the objective to find out the role of magnetic iron (Fe3O4) on mitigating the hazards of NaCl salinity, when applied at the rates of 0 or 3 g/20-cm-dimater plastic pot containing 10 fruits of arjuna and filled with about 3.5 kg of sand + clay mixture at equal parts (1:1, v/v) salinized with NaCl pure salt at the concentrations of 0, 2000, 4000, 6000 and 8000 ppm. The effect of interactions between Fe3O4 application rates and salinity levels was also studied in a complete randomized design experiment with factorial concept replicated thrice. The obtained results indicated that means of germination percentage were descendingly decreased with increasing salinity level to reach less than 50 % by 6000 and 8000 ppm levels, while planting the fruits in a soil mixture free from salt gave the highest germination %, followed by planting in 2000 ppm-salinized soil mixture, and then planting in soil mixture salinized with 4000 ppm concentration. On the other hand, addition of Fe3O4 (3 g/pot) significantly raised the mean of this measurement in both seasons. The shortest period to either maximum germination (G.V.) or 50 % germination (MGR) was achieved in both seasons by planting in non salinized control and 2000 ppm-salinized media, whereas increasing salinity level over that (up to 8000 ppm) prolonged these periods with the greatest delay in germination. On the contrary, Fe3O4 significantly reduced the means of such two traits causing a marked accelerating in G.V. and MGR. A slight increment was noticed in the means of germination rate index (GRI) by the different salinity concentrations, while Fe3O4 caused a trivial decrement. A similar response occurred as well regarding the means of vigour index (V.I.), seed viability (S.V.), hypocotyl length and vegetative and root growth attributes of the resulted seedlings. So, it can be advised to apply magnetic iron (Fe3O4) at the rate of 3 g/pot (20-cm-diameter) to improve germination and seedling quality of Terminalia arjuna Roxb. fruits planted in either low or medium salinized soil.

Effect of some Media on Artichoke Sprouts Production and Nutritional Values
Sprouts are excellent source of, amino acids, enzymes, minerals, phytochemicals and vitamins which are the most useful compounds for the human health. This study aimed to investigate the effect of three germination media (soil mixture consisted of soil + vermiculite + 10 % compost, rice straw and kitchen paper towel) on the production and nutritional value of sprouts artichoke comparing with artichoke heads. The highest sprouts yield was produced on soil mixture. On the other hand, based on dry weight, the comparison among sprouts produced on the different media, indicted that sprouts produced on kitchen paper towel showed the highest values of the most nutritional. Meanwhile, sprouts produced on kitchen paper towel exhibited significantly value higher contents of protein, total lipid, inulin, total sugars, calcium, sodium, phosphorus, antioxidants, the essential amino acids (such as leucine, isoleucine, threonine, phenylalanine and valine) than detected in artichoke heads. Reversely, artichoke heads significantly value higher contents of fibers, carbohydrates, phosphorus, vitamin A, vitamin C, total phenols, chlorogenic acid, cynarin, and the essential amino acid aspartic than all sprouts. The essential fatty acids (linoleic acid, linolenic acid) were determined in sprouts produced on soil mixture and rice straw, but they were not found in artichoke heads and produced on kitchen paper towel. According to the current results, it is recommended to collect artichoke seeds, before they are scattered in the soil at the end of the season, to be used in producing sprouts throughout the year as a source of healthy food and a protection from various serious diseases.
