Two field experiments were conducted at Private Farm Al-Doaa region, Baltim, Kafr Ash Shaykh, Egypt in 2015, 2016 seasons to study the effect of some osmo-regulators and/or antioxidants to ameliorate the harmful effects of salinity stress on Top Star hybrid sweet pepper (<em>Capsicum annuum,</em> L) plants in sandy soil under drip irrigation system, during the early summer season on vegetative growth, fruit yield and quality.The obtained results could be summarized as follows:Soil application of Kitasal (2 ml/l) gave the longest plant, heaviest fresh and dry weight, largest leaf area, and gave the highest fruit yield (ton/fed.) compared with other treatments in both seasons. All foliar applications significantly increased all studied parameters compared with the untreated plants. The superior application was 250 ppm glycine-betaine followed by Glutathione (50 ppm) or Potassium silicate (250 ppm) in both seasons, respectively. Interaction between soil application of Kitasal (2 ml/l) and foliar application of glycine-betaine (250 ppm) gave the highest values of vegetative growth represented by plant height, leaf area fresh and dry weight along with, fruit yield and its component represented by fruit weight, yield/plant, and total yield/fed. From the obtained results it could be concluded that, using Kitasal (2ml/l) as soil application in combination with foliar application of 250 ppm glycine-betaine improved both growth and yield of sweet pepper plants under salinity condition.

Two field experiments were carried out in the Experimental Station, Faculty of Agriculture, Mansoura University in the two summer seasons of 2014 and 2015 to study the effect irrigation water quantity and foliar application with salicylic acid on growth and yield of potato cv. Spunta grown under clay loamy soil conditions using drip irrigation system. The experiment layout was split plot in based on complete randomized block design with three replications. Quantity of irrigation water (700, 1000 and 1300 m<sup>3</sup>/ fed.) were present in the main plots, while foliar application with salicylic acid (0.0, 0.1, 0.2 and 0.3 g /litter.) were assigned in the sub plots. The results indicated that increasing water quantity up to1300 m<sup>3</sup>/ fed. led to a significant increase of vegetative growth parameters ( Plant height, leaves number, leaves area, number of main stem and foliage fresh weight per plant), leaves chemical composition (N, P, K, chlorophyll a, chlorophyll b and carotenoids), Tubers yield and its physical quality (tubers weight and number per plant, marketable and total yield), Tubers chemical quality ( Vit. C, TSS, N, P and K) and plant water relations (Relative water content). On contrary, foliage dry matter percentage, tuber dry matter percentage, hardness, density, electrolyte leakage and water use efficiency were decreased. With respect to the effect of foliar application of salicylic acid, the data exhibited that, the mentioned characters were increased compared to untreated plants except electrolyte leakage. The interaction between irrigation water quantity and spraying salicylic acid showed that the combination which consist of 1300 m<sup>3</sup>/ fed. and 0.2 g/l salicylic acid gave the highest values for most effective previous parameters.

An experiment was conducted out at a private orchard from Baharke town of Erbil province during 2016 season on pomegranate cv. Salimi. The age of trees was 13 years. Branches of one year old branches decapitated in February with three levels of 25, 50 and 75%. Suckers also were removed once in Feb, April and June. Results showed that 50% decapitation of branches + removal for twice of suckers gave the highest average for all vegetative and fruit traits as branches length and diameter, leaf area, leaf dry material and fruit size of 25.21cm, 25.13mm, 8.001cm<sup>2</sup>, 84.86%, 107.0 fruit tree<sup>-1</sup> and 33.23mm respectively. Furthermore this treatment reduced fruit drop percentage up to 4.33 %. It could be extracted that deputation and sucker removal were efficient to improve growth and yield components. Thus, accordingly, it is necessary to apply decapitation and removal of suckers to increase fruit yield of pomegranates.

To investigate the effect of faba bean plant populations (80000, 96000 and 120000 plants/feddan) resulted from the difference between hill spacing (30, 25 and 20 cm) and the efficiency of eight weed control treatments (butralin, metribuzin, oxadiargyl, each previous herbicides followed by one hand hoeing, two hand hoeing and unweeded check) on associated weeds, growth, yield and its attributes as well as chemical analysis. Two field experiments were conducted at the Experimental farm of El-Serw Research Station, Agricultural Research Center, Damietta Governorate, Egypt during winter seasons of 2015/2016 and 2016/2017. Main findings showed that increasing plant population from 80000 to 120000 plants/fedsignificantly decreased the broadleaved, grassy and total weeds dry weight by 46.32, 33.44 and 43.77% in the first season and by 45.99, 38.10 and 44.32% in the second season, respectively after 70 days from sowing. Plant population of 120000 plants/fed produced the highest values of plant height, dry weight/plant and LAI in both seasons. Moreover, sowing faba bean at 120000 plants/fedincreased seed yield/fed by 15.46 and 5.03% in the first season and 16.33 and 7.84% in the second season compared with 80000 and 96000 plants/fed, respectively. Two hand hoeing method significantly decreased the broadleaved, grassy and total weeds dry weight by 93.58, 99.24 and 95.68% in the first season and 92.62, 98.95 and 94.89% in the second season, respectively compared with the unweeded check. The results indicated that two hand hoeing method was the most superior treatment in increasing plant height, dry weight/plant and leaf area index at 70 and 90 days from sowing as well as yield, yield attributes and chemical composition of faba bean seeds followed by applying oxadiargyl herbicide with one hand hoeing treatment. It could be recommended that growing faba bean at plant population 120000 plants/fed integrated with two hand hoeing or oxadiargyl herbicide with one hand hoeing maximized seed yield per unit area.

A field trial was carried out during 2013/2014 and 2014/2015 seasons at the Experimental Farm of Faculty of Agriculture, Kafr El- Sheikh University to study the effect of bio, organic and chemical fertilization on growth, seed yield, essential oil and its main components as well as some chemical constituents (N, P and K) of Caraway plants. Compost was applied at the rate of 10 m<sup>3</sup> /fed., during soil preparation. NPK, active dry yeast, seaweed extract, amino acids free and triamin plus were added as folair spray. The common agricultural practices i.e. watering, weed control, etc. were done whenever plants needed and the obtained results could be summarized as follows: Compost in combinations with active dry yeast or amino acids free or triamin plus significantly enhanced both <em>Caraway</em> plant growth and productivity of seeds or essential seed oil contents. GCM (gas chromatography) analyses for oil components shown the presence of ơ–guaiene, 2,6- dihydroxyacetophenone, hydrocinnamic acid, α – gurjunene, chamigrene and caryophyllene in the seeds volatile oil. All treatments didn’t succeed in improving the main components of the volatile oil (carvone) but the plants fertilized with seaweed extract treatment gave high means of most component of the volatile oil.

The present study was carried out at Al-Amana nursery in Talkha district, Dakahlya Governorate, Egypt, during the summer season of 2014 to study the effects of different graft combinations between rootstocks and scion of watermelon (<em>Citrullus lanatus </em>(Thunb.) Matsum et Nakai) var. Lanatus cv. Aswan F<sub>1</sub>. The experiment included thirteen treatments resulted from the combinations of four rootstocks [Jumbo F<sub>1</sub> and Nun 6001 F<sub>1 </sub>hybrids [<em>Cucurbita maxima </em>(Duch.) ex. Lam.<em>×</em> <em>Cucurbita moschata</em> (Duch.) ex. Poir.], bottle gourd (<em>Lagenaria siceraria</em> Standl.) and pumpkin (<em>Cucurbita moschata</em> L.)] and three grafting methods [Hole insertion (HIG), Splice (SG) and Tongue approach (TAG)] as well as non-grafted plants as control. The obtained results illustrated that there was a high compatibility between Watermelon(scion) and Jumbo followed by bottle gourd then Nun 6001 rootstock, where these graft combinations recorded the highest vascular thickness and area of vascular cambium compared to other graft combinations. Although, SG gave the highest area of graft union. In addition, TAG showed the greatest width of graft union which is related to increase of xylem and phloem tissues thickness and area of vascular cambium. Moreover, grafted plants onto Jumbo and bottle gourd using TAG method recorded the highest survival percentage (100 and 98%, respectively) in comparison with other graft combinations. While, grafting onto pumpkin rootstock using HIG method had the lowest values of all studies traits in comparison with other combinations. Generally, the callus development and graft success in Watermeloncv. Aswan F<sub>1</sub>can be performed using Jumbo rootstock with TAG followed by SG method.

Two field experiments were conducted at EL-Kharga Oasis, Research Station, Desert Research Center (D.R.C.), New Valley Governorate, South Western, Egypt, during two winter growing seasons of 2015/ 2016 and 2016/ 2017 to study the effect of poultry manure extract (PME) as a foliar application (1, 2, 3 and 4 m<sup>3</sup>/ fed.) compared with control and soaking grains in selenium (Se) on growth, yield and its components and chemical composition of wheat. Increasing PME rates from 1 up to 4 m<sup>3</sup>/ fed .increased significantly all characters under study growth, yield and its components and chemical composition except % selenium compared to zero PME in both seasons. The differences between the two levels 3 and 4 m<sup>3</sup>/ fed. of PME were not significantly for plant length (cm), no. of tillers/ plant, no. of leaves/ plant, plant fresh weight, plant dry weight and all yield and its components in both seasons. The highest values of growth parameters, yield and its components were obtained by spraying of wheat plants with 3 m<sup>3</sup> PME / fed.in both growing seasons, while, chemical composition were obtained by 4 m<sup>3</sup> PME/fed.in both growing seasons. Increasing Se rates by soaking grains from 5.0 up to 10 mg Se/ l, increased all parameters under studied except, number of leaves/ plant and flag specific leaf weight F.S.L.W. mg/ cm<sup>2</sup>, spike length (cm) and number of spikelets/ spike and total carbohydrates % compared to zero selenium in both seasons. All concentrations of Se percentage of all chemical composition were significantly increased in both seasons. However proline were significantly decreased compared with the control in both seasons. The highest values of these parameters were obtained by soaking grains with 10 mg Se/ l while, the differences between this level and the high level 20 mg Se/ l were don’t significant in both seasons. Furthermore, the results showed that the interaction between PME foliar application and grains soaking with Se rates had a significant effect on all parameters studied in both seasons, except no. of leaves/ plant, flag specific leaf weight mg/ cm<sup>2</sup> and grains and % potassium were insignificant in the two growing seasons. The maximum increments for growth parameters, yield, its components and chemical parameters were obtained by spraying wheat plants by 3 m<sup>3</sup> PME/ feddan and grains soaking by 10 mg Se/ l in both seasons compared with the control except, leaves content of proline had the opposite trend of the other parameters. It could be concluded that grains soaking by Se (10 mg Se/ l) and foliar spraying of PME at 3 m<sup>3</sup>/ fed. At every 15 days after sowing in most cases led to increase wheat productivity under New Valley conditions.

Two field experiments were carried out at the experimental farm of Sakha Research Station, Kafrelsheikh, Egypt during 2016 and 2017 summer seasons to select the best weed control treatments for two Egyptian hybrid rice varieties under broadcasting method. Two rice hybrids {Hybrid-1 (Sk2034H) and Hybrid-2 (Sk2151H)}. Six chemical weed control treatments included; Penoxsulam 2.5% at two rates (0.018 and 0.024 kg ai ha<sup>-1</sup>) + Azimsulfuron 50% at rate of 0.014 kg ai ha<sup>-1</sup>, Bispyribac-sodium 2% at two rates (0.029 and 0.038 kg ai ha<sup>-1</sup>) + Azimsulfuron 50% at rate of 0.014 kg ai ha<sup>-1</sup>, and Fenoxaprop-ethyl 7.5% at two rates (0.045 and 0.063 kg ai ha<sup>-1</sup>) + Azimsulfuron 50% at rate of 0.014 kg ai ha<sup>-1</sup>, were applied as compared to weedy check plots (control). A split plot design with four replications was used where, rice hybrids were allocated in the main plots while weed control treatments were applied in sub-plots. The results showed that, H<sub>1</sub> rice variety (Sk2034H) recorded the lowest dry weight of grassy weeds, <em>C. difformis</em> and total weeds, and scored the highest rice dry weight, number of panicles per square meter, filled grains per panicle and rice grain yield, while H<sub>2</sub> was the best in 1000-grain weight and panicle weight during the two seasons. Bispyribac-sodium 2% at recommended dose (0.038 kg ai ha<sup>-1</sup>) or Fenoxaprop-ethyl 7.5% at reduced rate mixed with Azimsulfuron 50% at rate of 0.014 kg ai ha<sup>-1</sup> gave the lowest weed biomass and the best rice growth values in addition to yield and yield components in 2016 and 2017 seasons. The obtained results revealed that the best weed control, rice dry matter, yield and yield components were achieved by applying Bispyribac-sodium 2% at recommended dose (0.038 kg ai ha<sup>-1</sup>) or Fenoxaprop-ethyl 7.5% at reduced rate mixed with Azimsulfuron 50% at recommended dose (0.014 kg ai ha<sup>-1</sup>) with cultivation of Egyptian hybrid-1 (Sk2034H) except for panicle weight and 1000-grain weight of rice which obtained by H<sub>2</sub> rice hybrid treated with the same mixtures of herbicides during the two seasons of study.

Two field experiments were carried out in El-Gemmeiza Agricultural Research Station Agricultural Research Center, El-Gharbiya Governorate in 2016 and 2017 seasons to study the effect of foliar application with bentonite (times of application and rates) on leaf chemical composition, plant growth, earliness traits, fiber quality and yield of Egyptian cotton (<em>Gossypium barbadense</em> L.), Giza 86 cultivar. A split-plot design with three replicates was used. The main plots included three intervals at (squaring stage and flowering initiation), at (flowering initiation and the top of flowering) and at (squaring stage, flowering initiation and the top of flowering). The sub plots involved four rates of bentonite; (control "without application", spraying with 2, 3 and 4 kg bentonite/fed). The important results could be summarized as follow: Times of foliar application with bentonite gave significant effect on nitrogen, potassium, phosphorus, chlorophyll (a), (b), total chlorophyll and carotenoids concentrations in cotton leaves, in favor of foliar application with bentonite three times (at squaring stage, at flowering initiation and at the top of flowering). Leaves concentrations of nitrogen, potassium, phosphorus, chlorophyll (a), (b), total chlorophyll and carotenoids significantly increased with foliar application of 3kg bentonite /fed as compared with the other rates.The interaction between times of bentonite as foliar spraying and its rates had significant effect on chlorophyll (a), (b), total chlorophyll and carotenoids concentrations in cotton leaves, where foliar spraying with 3kg bentonite per fed three times (at squaring stage, at flowering initiation and at the top of flowering) produced the highest values of these traits. While, leaves N, P and K concentrations did not affect by this interaction. Times of application did not affect plant height and number of fruiting branches/ plant at harvest in both seasons. Bentonite at the rate of 2kg/fed significantly increased cotton growth parameters, <em>i.e., </em>plant height and number of fruiting branches/ plant at harvest as compared with the high rate of betonies(4kg/fed) in both seasons. The interaction significantly affected these two traits in the first season only, where the highest values of cotton growth parameters, <em>i.e., </em>plant height and number of fruiting branches/ plant were, generally, recorded with foliar application of bentonite at the rate of 2kg/fed three times(at squaring stage, at flowering initiation and at the top of flowering). However, the lowest values were recorded with foliar application of bentonite at the rate of 4kg/fed three times (at squaring stage, at flowering initiation and at the top of flowering).Times of foliar application with bentonite gave insignificant effect on earliness traits (numbers of total flowers and total bolls / plant, boll setting % and boll shedding %) in both seasons.Bentonite at the rate of 2kg/fed and at the rate of 3kg/fed significantly increased earliness traits (numbers of total flowers and total bolls / plant and boll setting %) and significantly decreased boll shedding % without significant differences between them as compared with the high rate of bentonite (4kg/fed) and control in both seasons. The interaction between times of foliar application and rates of bentonite significantly affected earliness traits (number of total flowers/ plant, number of total bolls/plant and boll setting %) in both seasons, where the highest values of number of total flowers/ plant, number of total bolls/plant and boll setting % and the lowest value of the boll shedding % were, generally, recorded with foliar application of bentonite at the rate of 2kg/fed or at the rate of 3kg/fed two or three times as compared with foliar application of bentonite at the rate of 4kg/fed two or three times and control treatment. Foliar application with bentonitetwice(at squaring stage and at flowering initiation) or three times (at squaring stage, at flowering initiation and at the top of flowering)significantly increased yield parameters (boll weight, seed cotton yield/plant and seed cotton yield/fed) in both seasons as compared with foliar application with bentonitetwice (at flowering initiation and at the top of flowering).On the other hand, seed index and lint % did not affect by time of application in both seasons. Foliar application of 2 or 3 kg bentonite per fed significantly increased boll weight, number of open bolls/plant, seed index, seed cotton yield/plant and yield of seed cotton/fed as compared with the control and using 4kg bentonite /fed in the two seasons of study. The interaction between times of application and rates of bentonite as foliar application had a significant effect on boll weight, number of open bolls/plant, seed cotton yield/plant and seed cotton yield/fed in both seasons, in favor of foliar application of bentonite at the rate of 2kg/fed or at the rate of 3kg/fed two times (at squaring stage and at flowering initiation) or three times (at squaring stage, at flowering initiation and at the top of flowering). While, seed index and lint % did not affect by the interaction between times of application and rates of bentonite as foliar application in both seasons. The times of foliar application and rates of bentonite as well as their interactions had insignificant effect on Pressley index and micronaire reading in both seasons. Conclusion: it could be concluded that the best foliar application rate of bentonite was 3kg per fed two times ( at squaring stage and at flowering initiation) for a significant positive effect on chemical composition, growth, boll setting and yield of cotton Giza 86 cultivar, under the conditions of El-Gemmeiza location.

One field experiment was carried out on clay soil in 2016 season and repeated in 2017 season in El-Gemmeiza Agricultural Research Station, Agricultural Research Center, El-Gharbiya Governorate, Egypt, to study the effect of seven treatments including foliar application with two rates of mepiquat chloride (pix); 2 and 3cm<sup>3</sup>/L, two rates of Kaolin (2 and 3g/L), two rates of mepiquat chloride(pix) and Kaolin application in combination (2cm<sup>3</sup>+2g)/L, (3cm<sup>3</sup>+3g)/Lthree times (at squaring stage, at the start of flowering and at the top of flowering) and control treatment on leaf chemical composition, plant growth, earliness, fiber quality and yield of Egyptian cotton (<em>Gossypium barbadense</em> L.), Giza 86 cultivar. A randomized complete blocks design with 3 replicates was used in both seasons. The important results could be summarized as follow:- The tested treatments had a significant effect on leaves N, P, K, chlorophyll a, b, total chlorophyll and carotenoids contents in the two seasons of study, where foliar application with mepiquat chloride at 3cm<sup>3</sup>/L in combined with kaolin at 3g/L three times recorded the highest values of these traits in both seasons followed by foliar application with mepiquat chloride alone at 3cm<sup>3</sup>/L. While, the control treatment produced the lowest values of these traits.Foliar spraying with mepiquat chloride at 3cm<sup>3</sup>/L in combined with kaolin at 3g/L three times significantly reduced final plant height, followed by foliar application with mepiquat chloride at 3cm<sup>3</sup>/L three times, foliar application with mepiquat chloride at 2cm<sup>3</sup>/L in combined with kaolin at 2g/L three times, foliar application with mepiquat chloride at 2cm<sup>3</sup>/L, foliar application with kaolin at 3g/L three times and foliar application with kaolin at 2g/L three times, while control treatment recorded the tallest plants. Number of fruiting branches/plant did not affect by these treatments. Foliar spraying with mepiquat chloride at 3cm<sup>3</sup>/L in combined with kaolin at 3g/L three times significantly increased numbers of total flowers and total bolls set/plant, boll setting and earliness percentages followed by foliar application with mepiquat chloride at 3cm<sup>3</sup>/L. But, the lowest values were obtained from the control treatment.Foliar spraying with mepiquat chloride at 3cm<sup>3</sup>/L in combined with kaolin at 3g/L three times significantly increased boll weight, number of open bolls/plant, seed cotton yield/plant, seed index and seed cotton yield/fed in the two seasons of study followed by foliar application with mepiquat chloride at 3cm<sup>3</sup>/L. But, untreated plants produced the lowest values.On the other hand, the tested treatments had insignificant effect on fiber quality (fiber strength and micronaire reading) and lint percentage in both seasons.This study demonstrates that foliar spraying with mepiquat chloride (pix) at 3cm<sup>3</sup>/L in combined with kaolin at 3g/L three times (at squaring stage, at the start of flowering and at the top of flowering) could be recommended to improve the chemical composition of leaves, vegetative growth traits, earliness, yield/feddan, yield components and fiber quality of Giza 86 cotton cultivar under conditions of El-Gemmeiza location.

Drought stress is one of the most harmful factors of plant growth and productivity. Two pot experiments were carried out at greenhouse of agriculture botany department, faculty of agriculture, zagazig university, Sharkya Governorate, Egypt, during two successive winter seasons (2014/2015 and 2015/2016), to study the role of proline or potassium in mitigation the harmful impact of drought stress conditions on wheat plants c.v Misr 2 grown in Egypt. Growth parameters, yield and biochemical constituents were evaluated.Results show that all plant growth characters studied (shoot dry weight, leaf area and plant height) as well as yield and its components <em>(</em>dry weight of grains /plant, number of spikes/plant, number of grains/plant, number of grains/ spike, and1000-grains weight) were decreased with increasing irrigation intervals (irrigation every 10, 20 and 30 days) during the two successive growing seasons.The most effective treatment was Irrigation every 30 days in decreasing yield and its components. Integrated application of proline or potassium at rate of 0.1 and 0.2 % alleviated these negative effects by enhancing the growth and productivity. However, these increases were less than the control treatment. Moreover, it was found that drought stress decreased RWC, ELWR, RWL, photosynthetic pigments contents, whilst increasing, total phenol, proline as well as peroxidase and catalase activities in the leaves of wheat plants during the two growing seasons. However, application of proline or potassium increased all these parameters and decreasing total phenols. Treatment of proline at rate of 0.2 % was the most effective in this respect. It is recommended that application of proline or potassium can fully or partially counteract the adverse effect of drought stress on growth, and productivity of wheat plants through their effects on biochemical constituents

A greenhouse experiment was conducted at the Department of Horticulture, College of Agriculture, University of AL-Anbar during 2017 season to investigate effect of spraying extracts of garlic and licorice root on vegetative, root and floral trait of <em>Gazania splendes</em> L. Treatments were randomly distributed under RCBD design with three replicates. Each treatment involved six plants. The design included two factors; one represented three concentrations of garlic extract viz. 0, 2 and 4 ml<sub>Gex</sub>.l<sup>-1</sup>DH2O, the second one was four concentrations of licorice root extract viz. 0, 1, 3 and 5 gm<sub>Lex</sub> DH<sub>2</sub>O. Results revealed that spraying of 2 ml garlic extract per liter causes the highest increase of leaves No., fresh weight, dry weight, root length, the time to flower opening, flowers No. and flower diameter of 59.83 leaf.plant<sup>-1</sup>, 51.67gm, 10.18gm, 46.70cm, 99.33d, 6.75 flower.plant<sup>-1</sup> and 5.458 cm, respectively. Furthermore, licorice extract spraying at 1gm per liter gave significant increase on leaves No., fresh weight, dry weight, time to flower opening, flowers No. and flower diameter at 71.11 leaves.plant<sup>-1</sup>, 58.86gm, 12.39gm, 98.89d, 7.00 flower.plant<sup>-1</sup> and 5.589 cm, respectively. The combinations of 2ml garlic.L<sup>-1 </sup>+ 1gm licorice.l<sup>-1</sup> achieved highest average fresh weight, dry weight, and time of flower opening of 74.21gm, 15.47gm and 93.67d, respectively. Thus, it could be concluded that spraying of garlic and licorice extracts were effective and efficient in improvement of vegetative, root and floral trait of Gazania.
