Vines were planted in sandy soil spaced 3X2 meters apart and irrigated by drip irrigation system and supported by Gable system. The study included time of bud burst, young shoots, young leaves, shoot, and time of bloom, flower, mature leaf, beside determining time of ripening, Bunch, berry, Tss, Acidity, Tss / acid ratio, and seed formation.The studied cultivars were characterized by good vegetative growth and good fruit quality. The tips of the studied cultivars were fully open Color of upper side of blade for the young leaf was green with anthocyanin spots in Arra 30, Arra 29, and Arra 24, but dark copper- red in Arra 13, and Arra 27, while light copper-red in Arra 15. The internode was long, thick and number of consecutive tendrils were less than three in all cultivars. The tip of tendril was tri-fid in Arra 29 & 15 while di-fid in Arra 13, it was di-tri in Arra 30,Arra 24 and Arra 27. The length of tendril was very long in Arra 30, Arra 29, and Arra15 and long in Arra 13, Arra 24 and Arra 27. Entire of cultivars had flowers with male and female parts fully stamens and developed gynoecium in all studied cultivars. The shape of blade was circular in Arra 27, and Arra 15, and pentagonal in the other cultivars. Depth of upper lateral sinuses was shallow in Arra 29 , Arra 27 and Arra 15 while was very deep in Arra 30 , Arra 13, and Arra 24. Arrangement of lobes of upper lateral sinuses was closed in Arra 27, and Arra 15, but slightly overlapped in the others . Petiole sinus slightly open at Arra 30, Arra 24, and Arra 15, wheaser half open in Arra 13, and Arra 27, and wide open in Arra 29. Petiole shape was u- shape in Arra 29, , Arra 13, and Arra 24, while it was v-u shape at the others. Length of petiole as compared to middle vein was moderately shorter as well as sinus limited by veins which was constantly absent in all cultivars. Anthocyanin pigment of main veins on the upper side of blades was strong in Arra 30, very low in Arra 29, low in Arra 24, and absent in the others. Yield / Feedan data showed that consequently for the studies cultivars were Arra 15> Arra 29 > Arra 30> Arra 27> Arra 24> Arra 13.Bunch weight of all studied cultivars was big, bunch shape was shouldered in Arra 30, Arra 27, and Arra 15, conical in Arra 29, and Arra 13, while winged in Arra 24. Berry shape in Arra 30, Arra 13, and Arra 15, was cylindrical and obtuse ovoid in Arra 29, And Arra 27, while broad ellipsoid in Arra 24.

E. A.Nemeata AllaSugar Crops Res. Inst., Agric. Res. Center, Giza, EgyptJournal Article20190716Two field experiments were carried out in 2015/2016 and 2016/2017 seasons at Sakha Agricultural Research Station, Kafrelsheikh Governorate (latitude of 31.10<sup>0</sup> N and longitude 30.93<sup>0</sup> E, at an elevation of 14 m above sea level) to find out to the appropriate fertilization level of boron and its application time on growth, yield and quality of sugar beet crop. The present work included twelve treatments represent the combinations of four levels of boron (zero, 50, 100 and 150 ppm) and three application times of 30, 60 and 90 days after sowing. Boron was sprayed on beets as a boric acid 17% boron. The experimental design was strip plot with four replicates, where vertical plots were occupied with boron levels, while the horizontal plots were devoted to the three application times. The results showed that increasing boron application to 100 and/or 150 ppm resulted in higher values of root diameter, root fresh weight/plant, foliage fresh weight/plant, sucrose%, sugar extractable% and quality index as well as root, top and sugar yields/fed, at harvesting time in both seasons, whilst sugar lost to molasses%, Na and K contents significantly decreased.It was found that boron application time had a significant effect on root diameter, root, and foliage fresh weight/plant as well as top yield/fed of sugar beet in both seasons, as well as sugar yield/fed in the 1<sup>st</sup> one, where the application time of 90 days achieved the highest values of the mentioned traits. However, root impurities (Na, K and α-amino-N) and sugar lost to molasses% were insignificantly affected by the time of boron application. The interaction between boron concentration and its application time significantly affected root fresh weight/plant in both seasons and root yield/fed in the 1<sup>st</sup> season only. The combination of (150 ppm boron fertilization at 90 days of sowing) attained the highest values of root fresh weight (9, 796 g and 1, 769 g) in the two seasons respectively, as well as the maximum root yield (60, 22 ton/fed) in the first season only. Under conditions of the present work, fertilizing beets with 100 and/or 150 ppm boron as foliar application at 90 days from sowing can be recommended to get the highest root and sugar yields/fed.https://jpp.journals.ekb.eg/article_41113_d7c56b8fff6e711193d2566965fde4d4.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-366981120171101Impact of Potassium Silicate Compound as Foliar Application on the Growth, Yield and Grains Quality of GIZA 179 Rice Cultivar.107710834111510.21608/jpp.2017.41115ENMariam T.WissaRice Research Department (RRD), Field Crops Research Institute (FCRI), Agricultural Research Center (ARC), Giza, Egypt.Journal Article20190716 Two field experiments were conducted at the Experimental Farm of Rice Research Department (R.R.D.), Sakha, Kafrelsheikh, Egypt during 2015 and 2016 seasons. In order to examine the impact of potassium silicate compound as foliar application on the growth, yield and grains quality of Giza 179 rice cultivar. A randomized complete block design (R.C.B.D.) with four replications was used in the two seasons. Foliar applications of potassium silicate, at the rate of control (without potassium silicate), 0.5%, 1.0%, 1.5% and 2.0 % potassium silicate were sprayed twice with the same concentration at 15 and 30 days after transplanting. The studied characters were; chlorophyll content in flag leaf, leaf area index, dry matter accumulation, plant height, no. of tillers per m<sup>2</sup>, no. of panicles per m<sup>2</sup>, panicle length cm, panicle weight g, total no. of grains per panicle, thousand grain weight, grain yield ton/ha, percentages of hulling, milling and head rice and silicon content in stems, grains and straw .The results showed that application of potassium silicate caused an increased in growth characters, yield, yield attributes and grains quality of Giza 179 rice cultivar. Potassium silicate at the rate of 1,0% produced the maximum values of chlorophyll content in flag leaf, leaf area index, dry matter accumulation, plant height, number of tillers/m<sup>2</sup>, number of panicles/m<sup>2</sup>, length of panicle (cm), weight of panicle (g), grain yield(ton/ha), as well as, hulling, milling, head rice percentages of Giza 179 rice cultivar, while sprayed Potassium silicate at the rate of 1.5 % resulted the maximum total number of grains/panicle and the rate of 2.0% produced the maximum silicon content in stems, grains and straw. All the other parameters showed overlapping results of different potassium silicate levels. According to the previous results, it could be concluded that using potassium silicate as foliar application twice with the same concentration 1.0% at 15 and 30 days after transplanting was the best treatment for improving growth and obtaining the greatest grain yield besides the grains quality of Giza 179 rice cultivar. https://jpp.journals.ekb.eg/article_41115_f3f24a326c9692c16bf214575aa84499.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-366981120171101Response of Egyptian Hybrid Rice One Cultivar to Zinc Sulphate, Potassium Sulphate and Magnesium Silicate as Foliar Application.108510924111610.21608/jpp.2017.41116ENMariam T.WissaRice Research Department (RRD), Field Crops Research Institute (FCRI), Agricultural Research Center (ARC) , Sakha, Kafr El-Sheikh ,Egypt.Journal Article20190716The two field experiments were conducted during 2015 and 2016 seasons at the Experimental Farm of Rice Research Department (RRD), Sakha, Kafrelsheikh, Egypt. In order to examine the response of Egyptian hybrid rice one cultivar to foliar application of zinc sulphate, potassium sulphate and magnesium silicate. A randomized complete block design (R.C.B.D.) with four replications was used in the two seasons. The used treatments of foliar applications of zinc sulphate, potassium sulphate and magnesium silicate were used as follows: (T<sub>1</sub>)<sub>,</sub> control (without any application of the three tested compounds); (T<sub>2</sub>), Zinc sulphate; (T<sub>3</sub>), potassium sulphate; (T<sub>4</sub>), magnesium silicate; (T<sub>5</sub>), Zinc sulphate + potassium sulphate; (T<sub>6</sub>),Zinc sulphate + magnesium silicate; (T<sub>7</sub>), potassium sulphate + magnesium silicate and (T<sub>8</sub>), Zinc sulphate + potassium sulphate + magnesium silicate. The foliar applications treatments were applied twice with the same concentration 2% at 15 and 30 days after transplanting. The studied characters were; plant height (cm), leaf area index, dry matter accumulation (g/m<sup>2</sup>), chlorophyll content in flag leaf ( SPAD-Value), number of tillers per m<sup>2</sup>, number of panicles per m<sup>2</sup>, number of grains per panicle, panicle weight (g), filled grain percentage, thousand grain weight, grain yield(ton/ha) and hulling, milling, head rice and milled grain protein percentages. The results showed that combined foliar application of the three tested compounds caused an increased in the previous studied growth characters, yield, yield attributes and grain quality of the Egyptian hybrid rice one cultivar. While, control treatment (without spraying) resulted maximum thousand grain weight (g) without significant differences between control and combined application of the three tested compounds in this criteria. All the other parameters showed overlapping results of different foliar application treatments. According to the previous results, it could be concluded and that: Using foliar application of zinc sulphate, potassium sulphate and magnesium silicate twice with the same concentration 2.0% at (15 and 30 days after transplanting) was the best treatment for obtaining the greatest grain yield besides improving growth and the grain quality of Egyptian hybrid rice one cultivar. Using of the previous fertilizer compounds as foliar spray saved about more than two thirds from the amount of zinc sulphate and potassium sulphate if applied as basal application which is a result to application of magnesium silicate which caused integration with zinc sulphate and potassium sulphate. https://jpp.journals.ekb.eg/article_41116_7066bd439ebaf12f4ba80f77bfd5b9d5.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-366981120171101Response of some Sorghum (Sorghum bicolor, L.

There were Many studies attempted to solve these problems. Thus, this study is conducted to investigate the effect of foliar spraying riboflavin at different concentration on growth traits, proline content in the plant, grain yield and yield components of three sorghum cultivars. Results revealed that Rabih cv. was significantly superior in most studied traits, such as plant height, leaf area, leaf area index, flag leaf area, leaves proline content and number of grains per head. This increment in the traits mentioned previously reflected positively on grain yield per unit area in both seasons as it produced 7.05 and 7.12 ton/ha, respectively. Foliar application of riboflavine improved most of vegetative growth traits including plant height and leaf area, while it reduced the proline content in plant which make it able to avoid stress during its life time. This in turn increased the grain yield and its components. In both season, foliar application of riboflavin at the conc. of 300 mg l<sup>-1</sup> gave the highest grain yield amounted to 7.29 and 7.22 ton h<sup>-1</sup>, respectively. There were significant interaction between cultivars and riboflavin conc. in most traits.

The experiment aims to study the effect of useing different fertilizers including (NPK), ureaform (UF), compost (C), Sheep manure (S), humic acid (HA), and yeast extract (YE) on growth, productivity and quality of Maize yield (<em>var., </em>Hi-Tech 1100). The experiment was a Randomized complete Block design (RCBD) with three replicates.The treatments were six: (T<sub>1</sub>) Check treatment full recommended NPK (Control), (T<sub>2</sub>) = (CS + UF), (T<sub>3</sub>) = (YE + UF), (T<sub>4</sub>) = (HA + UF), (T<sub>5</sub>) = (CS + YE) and (T<sub>6</sub>) = (CS + HA). In both seasons, the combination of 10 tons fed<sup>-1</sup> of compost and sheep manure plus 50 kg fed<sup>-1</sup> of ureaform (T2) resulted in the highest growth, yield and yield components and quality of maize as comparedto the others treatments. The effect of different combination from the used fertilizers could be arranged in the following descending order T<sub>2 </sub>> T<sub>6</sub> > T<sub>5</sub> > T<sub>4</sub> > T<sub>1</sub> >T<sub>3</sub>. Treatment (T<sub>2</sub>) gave the highest grain yield (3494 and 3676 kg fed<sup>-1</sup>) with an increase of (29.31 and 21.84%) as compared to T<sub>3</sub> (2702 and 3017 kg fed<sup>-1</sup>) during 1<sup>st</sup> and 2<sup>nd</sup> seasons, respectively. The NPK maize grain content as affected by different combination could be arranged in the following descending order T<sub>3</sub> < T<sub>1</sub> < T<sub>4</sub> < T<sub>5</sub> < T<sub>6</sub> < T<sub>2</sub>. Also, compost and sheep manure addition improved soil properties since they increased organic matter content and decreased soil reaction (pH). Finally, it could be concluded that the integration of organic and inorganic fertilizers was better than using organic or inorganic fertilizer separately. Using the high amount of organic fertilizers (10 ton fed<sup>-1</sup> CS) with ureaform (50 kg fed<sup>-1</sup> UF) was the best treatment for producing high quality and increasing yield of maize crop under Upper Egypt conditions in Assiut.https://jpp.journals.ekb.eg/article_41121_dee1ec79ceae7369774ca39f9401fdbe.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-366981120171101Impact of Magnetized Water Irrigation, Soil Mineral Fertilization and Foliar Spraying with Nanomaterial on Potato Plants.111311204112310.21608/jpp.2017.41123ENSamar M.

H.HassanDesert Research Center, Cairo, EgyptW. M.HassanyDesert Research Center, Cairo, EgyptJournal Article20190716Fodder Beet is potentially the highest yielding winter forage crops and is high in energy, palatability and digestibility. However, due to susceptibility of fodder beet to salinity at early growth stages and a relatively long growing season, transplanting technique and appropriate sowing date could help to fodder beet production particularly in saline soils. Therefore, two field trials were conducted in Agricultural Experimental Station of Desert Research Center at Tegzerty, Siwa Oasis, Matrouh Governorate, Egypt during 2006/2007 and 2007/2008 growing seasons. These trials were carried out to study the effect of four planting dates i.e. 15 Oct., 30 Oct., 15 Nov., 30 Nov. and two planting methods i.e. direct seeding and transplanting at 45 days on fodder beet productivity under saline conditions.Results indicated that top fresh or dry weights as well as fresh and dry weights of root either per plant or fed. (fed. =0.42 ha.) were decreased with delaying planting dates from 30 Oct. to 30 Nov. in both growing seasons. These reductions may be attributed to reducing length and diameter of roots with delaying planting dates. Whereas, number of harvestable plants/fed., at harvest, was increased with delaying planting date up to the 3<sup>rd</sup> planting date of 15 Nov. and after then it was decreased with the latest planting date at 30 Nov. Moreover, the percentage of abnormal roots (%) was significantly decreased with delaying planting dates in both growing seasons.Concerning the effect of planting methods, transplanting method markedly increased number of harvestable plants and abnormal root percentage as comparing with the traditional planting method of direct seeding in both growing seasons. Furthermore, top and root fresh or dry weights per plant were decreased with planting fodder beet by transplants. However, fresh or dry fodder beet yield/fed. was increased with planting method of direct seeding in the 1<sup>st</sup> growing season, but did not reach to a significant level in the 2<sup>nd</sup> one. These increments may be due to one or more the following reasons; increasing fresh or dry root/plant, top fresh or dry weight/plant, root length and/or root diameter.https://jpp.journals.ekb.eg/article_41128_ecd173f6c63dd0d64b8e571ce12c69a3.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-366981120171101Response of Tomato Plants to Irrigation with Magnetized Water and some Foliar Application Treatments under Drip Irrigation System: 1- Vegetative Growth and Chemical Constituents of Leaves.112711334113010.21608/jpp.2017.41130ENK.

Results indicated that the highest values of vegetative growth characteristics, <em>i.e.,</em> plant height, number of branches, number of leaves, leaf area, fresh and dry weights as well as chemical constituents of leavesas photosynthetic pigments (Chl. a, Chl. b, total Chl. a+b and carotenoids) and leaf minerals content (N, P, K, Ca, Mg, Zn, Mn) were recorded when plants irrigated with magnetized water as compared with plants irrigated with untreated water in both studying seasons. On the other hand, Fe content responded negatively to irrigation with magnetized water.Comparing the effect of foliar applications, all foliar application treatments significantly enhanced vegetative growth parameters, leaf minerals and pigments contents compared to the check treatment. Foliar application of chitosan at 250 ppm is the superior in its effect on all the aforementioned characteristics followed by yeast extract at 10 g/L then lithovit at 1.5 g/L in the two seasons except for Fe content. The best results of both vegetative growth attributes and chemical constituents of leaves were recorded when plants irrigated with magnetized water and sprayed with chitosan at 250 ppm in both seasons.

These experiments aimed to evaluate the effect of some combinations between four levels of mineral fertilizer with two types of organic fertilizer produced from biogas digester system (dried and liquid residuals) as well as farmyard manure beside the control treatment on growth, yield and fruit quality of sweet pepper (Capsicum annum L.) cv.California wander as a local famous variety, grown under open field conditions. All organic sources gave rise to a positive effect on plant growth expressed as plant height, number of branches per plant, number of leaves per plant, leaf area per plant, foliage fresh weight and foliage dry weight per plant and increased the percentage of essential macro and micro elements in pepper plant leaves, also produced the highest values of early and total yield and enhancing the fruit quality. Moreover, it increased TSS and ascorbic acid in the fruits as compared with those plants fertilized with mineral NPK alone without organic sources (control). In this concern, dried biogas residual organic fertilizer was the superior source of organic fertilizer, used in this study, which it showed the highest results comparing with the other sources i.e., liquid biogas residual organic fertilizer or farmyard manure. In pepper plants, increasing NPK rate from 25% to 100% of the recommended dose led to an increase in plant vegetative growth. Moreover essential macro and micro elements were increased also in plant leaves. Likewise, early and total yield and the fruit quality i.e., physical fruit quality TSS and vitamin C were enhanced. The promising combination was 50% from the recommended NPK plus 20 m<sup>2</sup> dried biogas digester residual organic fertilizer, which gave the best values of plant growth and yield, also fruit characters were enhance.Concerning the economical evaluation, adding the 50% of recommended NPK combined with 20 m<sup>2</sup> dried biogas digester residual organic fertilizer led to obtain the highest total yield of pepper plants as well as total revenue as compared with the other treatments under this investigation.https://jpp.journals.ekb.eg/article_41131_d1cb7ed5cf7b59e4cb25ed6dd51a66eb.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-366981120171101Improvement System of Rice Intensification (Sri) For Some Rice Genotypes114711514113410.21608/jpp.2017.41134ENA.

Results indicated that all applied soil substances significantly enhanced vegetative growth parameters, chemical constituents, endogenous phyto-hormones of leaves, yield and fruit quality compared to the control in both growing seasons of study. Soil applications of either zeolite or compost are the best treatments in enhancing most of the aforementioned parameters. Additionally, our results undoubtedly confirm that the application of zeolite or compost could decrease chemical fertilizers through improving the efficiency of both fertilizers and irrigation water which in turn increase vegetable crops production, minimize economic costs as well as limit environmental contamination.https://jpp.journals.ekb.eg/article_41137_afcee63b7ed9a8c2929f12e1b9277489.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-366981120171101Effect of Sowing Dates, Irrigation Intervals and Organic Fertilizers on Growth and Productivity of Pea Plants (Pisum sativum L.) under Sandy Soil Conditions115911754113810.21608/jpp.2017.41138ENS.

Trimming of hands was done after bunch shooting, seaweed extract sprayed three times: 1) after bunch shooting directly, 2) 15 days later 3) 30 days later. Time to harvesting, bunch weight (kg), estimated yield (ton), estimated increasing rate of yield (%), finger diameter (cm), finger weight (g) finger length (cm), soluble solids content (SSC) and titratable acidity percentage were determined. Obtained results showed that trimming with two hands gave the highest values for the above mentioned characters compared with one hand. Time of harvesting tended to decrease with hand trimming of banana. The highest values of bunch weight, yield, increasing rate of yield and finger parameters were obtained from Grand Nain banana plants trimming two hands with spraying seaweed extract at 2 % .Seaweed (<em>Ascophyllu mnodosum </em>L.<em>)</em> is a known source of plant growth regulators which an important roles in metabolism and productivity of plants. Moreover, hand trimming is practiced to increase the finger parameters. From the obtained results it could be concluded that, spraying seaweed extract at 2% with trimming two hands improved time to harvesting, yield as well as physical and chemical characteristics of the fruits of Grand Nain banana plants. A superior effect was attributed to using seaweed extract and trimming rather than control.https://jpp.journals.ekb.eg/article_41285_fe5a1e4a1f0ef5772564979c5ef2fd9e.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-366981120171101Effect of Organic Nutritional Supplement on Growth, Nodulation and Yield of Peanut Cultivated Under Different Fertilization Systems120512134128610.21608/jpp.2017.41286ENFatma A.

Two field experiments were carried out in extension field at Quweisna, Menoufia governorate, Egypt during the two growing seasons of 2015 and 2016. Results indicated that adding fertilization systems and organic substances generally had effective roles on enhancement of growth and yield of peanut grown in sandy loam soil. Application of 50 % compost + mineral ores mixture produced the highest growth characters i.e number of main branches and leaves /plant, stem and leaves dry weight/plant and leaf area/plant . However, application of 100 % compost exhibited more total chlorophyll content, number and nodules weight/plant, yield and its components (number of pods/ plant, number of seeds / pod, weight of seed /plant and pod yield per plant and per fed and seed oil percentage compared with other tested fertilization treatments. The response of peanut Chlorophyll and nodulation, yield and oil percentage significantly differed by foliar application of organic substances. Application of Jeta Plus (KP) and Si-ElGhanem (KSi ) surpassed the other organic substances for producing highest values of most above mentioned characteristics. However, untreated plants recorded the lowest values of all studied characteristics. The interactions between the fertilization systems and organic substances were found to be significant for most studied traits. The maximum pod yield/fed was obtained by soil application of 100 % compost combined with foliar application with KP, which is found to be the best combination for maximizing peanut productivity. Accordingly, the study recommends the importance of regular use of organic fertilization as soil or foliar application to reduce the need for synthetic commercial fertilizers and reduced soil pollutions.https://jpp.journals.ekb.eg/article_41286_db408099438875049e42eee780c0c1d7.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-366981120171101Genetic Analysis of Yield and Its Components in Some Bread Wheat Crosses (Triticum aestivum L.) using Five Parameters Model.121512204129210.21608/jpp.2017.41292ENE.

An general, sprayed Giza 102 variety twice by the natural Chitoker at 250 ml. / 100 L. rate during vegetative and pre- flowering stages produced the highest yield, yield components and oil yield.The results of the calculation of the economic yield of the crop showed that the cultivation of the sunflower crop in Giza 102 + spraying with the natural compound Chitoker rate of 250 ml./100 liters of water in two stages are spraying in the stage of vegetable growth and spray in pre-growth flowering Is the best experimental economic transaction for the farmer, With some other factors being given an economic rate but to a lesser degree. This study concluded that the cultivation of Giza 102 sunflower variety + spraying twice with the natural compound Chitoker rate of 250 ml./100 liters of water in two stages of vegetable and pre-growth of the Zahra under the conditions of Siwa Oasis gave the best results economically.https://jpp.journals.ekb.eg/article_41305_678adb4bec0af35efa5ac77ae5b43a62.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-366981120171101Response of Red Globe Grapevines to Spraying Barley Seed Sprout and Silicon126112654130710.21608/jpp.2017.41307ENA.

The selected vines were sprayed three times with such two stimulants. Barley seed sprout and potassium silicate each at 0.025 to 0.1% single and combined applications improved growth aspects, leaf pigments, some nutrients, berry setting %, yield and fruit quality compared to the control treatment. Using combined applications was superior to using each alone.The effect on these parameters depended on increasing concentrations. Spraying a mixture of barley seed sprout and potassium silicate three times each at 0.05% improved yield and quality of Red Globe grapevines under Minia conditions.https://jpp.journals.ekb.eg/article_41307_368cfb34c962e1e15c8a779b0869300f.pdfMansoura University, Faculty of AgricultureJournal of Plant Production2090-366981120171101Effect of Irrigation and Potassium Fertilizer on Vegetative Growth, Yield and Quality of Globe Artichoke Plants under Sandy Soil Conditions126712764130810.21608/jpp.2017.41308ENR.

Cen., Giza, EgyptJournal Article20190717A field experiment was carried out during 2014/2015 and 2015/2016 seasons at El-Kassasin Horticulture Research Station, Ismailia governorate, Egypt, to study the effect of irrigation and potassium fertilizer treatments on vegetative growth, yield and quality of globe artichoke plants under drip irrigation system in sandy soil. The experiment was designed as split plot. Main plots devoted to irrigation treatments which included irrigation with 100% of ET<sub>c</sub> (I<sub>1</sub>), 80% of ET<sub>c </sub>(I<sub>2</sub>) and 60% of ET<sub>c </sub>(I<sub>3</sub>). While potassium fertilizer treatments were in the sub-plot. Potassium fertilizer treatments were 100% of recommended potassium fertilizer dose (K<sub>1</sub>), application of 75% and 50% from recommended potassium fertilizer dose plus 1% foliar potassium citrate (K<sub>2</sub> and K<sub>3</sub> respectively). Results indicated that the highest values of plant height, leaf fresh and dry weight, number of offshoots plant<sup>-1</sup>, flower heads fresh weight and diameter, fresh weight and diameter as well as thickness of receptacle, number of early and total flower heads plant<sup>-1</sup> and total yield fed<sup>-1</sup> were obtained from I<sub>1 </sub>and K<sub>1</sub>, while the lowest values resulted from I<sub>3</sub> and K<sub>3</sub>. There were no significant differences between K<sub>1</sub> and K<sub>2</sub> potassium treatments for all characteristics, as well as between I<sub>1</sub>× K<sub>1 </sub>and I<sub>1</sub>× K<sub>2</sub> interactions in the two growing seasons. Seasonal applied water was 39.32, 31.63 and 23.97 cm when globe artichoke plants were irrigated with 100, 80 and 60% of ET<sub>c</sub> respectively. The highest values of productivity of irrigation water (PIW) resulted from irrigation with 60% of ET<sub>c</sub>. At the same time, potassium treatments of K<sub>1</sub> and K<sub>2</sub> not only resulted in higher yield but also increased the PIW. Generally, it could be concluded that under study condition irrigation with 100 ET<sub>c </sub>and application of 75% from recommended potassium fertilizer dose plus 1% foliar potassium citrate was the best combination for globe artichoke yield and its quality. When water becomes limiting factor, the treatment of I<sub>3 </sub>x K<sub>2</sub> could be recommended.https://jpp.journals.ekb.eg/article_41308_6d5c98f01b21a85c91b9b2bb2e053948.pdf
