Effect of Organic Compost Tea and Humic Acid to Reduce Dose of NPK Fertigation of Banana Plants cv."Grand Nain"
THIS EXPERIMENT was carried out during two successive crop ……. cycles of 2013/2014 (first ratoon plant) and 2014/2015 (second ratoon plant) of Giant Cavendishi banana (Musa spp. AAA sub group) cv. Grand Nain, grown in sandy soil. The goal of this research is to study beneficial effect of compost tea (compost extract), which abstracted by 1.0 kg/10 L water or 2.0 kg/10 L water and humic acid ( 2.5 g/L water or 5 g/L water) single or incombination to reduce the doses of chemical fertigiation by 20% of the recommended rate NPK(N:640 , P2O5: 80 ,K2O: 800 g/plant/year)in nine equal doses and added at monthly from March to Nov. on the growth, yield and fruit quality of Grand Nain banana. The dose of both treatments(compost tea) was 9 liter/hole for each date and humic acid was 3liter /hole for each date, compared to standard treatment NPK fertigation 100% of the recommended rate (N: 800, P2O5: 100, K2O: 800 g/plant/year) as a control.
The results revealed that the plants receiving 80% NPK of the recommended rate plus compost tea (2.0 kg/10L water or 1.0 kg/10 L water) andthe combination with humic acid (2.5 g/L water or 5.0 g/L water) treatments showed an increases in the vegetative growth parameters (psedostem height, circumference and assimilation area compared with the standard treatment of NPK fertigation (100%). The highest values of yield and leaf contents of N and K were obtained from plants received (NPK fertigation 80% of the recommended rate pluscompost tea 2kg/10L and humic acid 5 g/L) while, the lowest values were obtained with the plants received 80% NPK of the recommended rate only but had no significant effect on leaf P content. Organic compost tea(2kg/10 L/water) and humic acid (5 g/L water) was favorable for improving fruit quality in terms of increasing finger weight (119.00 & 124.00 g), total soluble solids % (22.21& 22.05 %), total sugars (18.47 & 18.16) compared with the other treatments. accordingto the obtained results, it can be concluded that using compost tea(2 kg/10 L water ) in combination with humic acid (5 g / L water ) reduce the recommended doses of the chemical fertilizers by 20%.

Effect of Pre-Grafting Incubation and Grafted Cuttings Positionon Grape Grafting Success
THIS EXPREMENTS was carried out during two successive ……..seasons 2015 and 2016 at the nursery of pomology department, Faculty of Agriculture, Cairo university, Egypt. The study was aimed to investigate the effect of two fators namely i.e, pre-grafting incubation and grafting materials position during callusing on grafting success of flame seedless grapes onto Salt Creek rootstock. Callusing was carried out in three positions i.e, horizontal, upright and upright down either with or without pre-grafting incubation. The results showed that either pre-grafting incubation or callusing at uprightposition increased significantly callus percent and degree, sucker number, rooting rate, bud break percent during callusing period and grafting success percent. The interaction, betweentreatments revealed thatcallusing at uprightpositionaccompanied with pre-grafting incubation gave the best results in this respect. It can be concluded that callusing at uprightposition either with or without pre-grafting incubation increased grafting success significantly compared to callusing at horizontal or upright down position.Chemically, higher grafting success is accompanied with lower phenols, reducing sugars and total indoles. It may be concluded that there is no antagonistic effect between root and callusformation in grafted cuttings. Also, upright position for incubation the grafted cuttings are better than pre-grafted incubation in increasing grape grafted cuttings.

Using Different Methods to Produce Vegetative Carob Seedlings
A FIELD experiment was conducted during 2014-2015 to study the influence of different indole butyric acid (IBA) concentration (4000, 6000 and 8000 ppm) on rooting of Carob air layers and cuttings at Horticulture Research Institute Egypt, during February, May, August and November. The results indicated that, May is the best time to make air layering. Applying IBA at 4000 ppm had recorded the longest root for genotypes (1, 3 and 4) in both seasons. IBA at 6000 ppm gave the best percentage of rooting and survival and number of root for genotype (1) and longest root for genotype (5) while, treated with IBA at 8000 ppm registered the highest percentage of rooting and survival also the number of root for genotypes (3- 4 and 5). The percentage of rooting and survival Carob stem cuttings was very low (35 and 51.7% maximum) respectively. The genetic polymorphism between the four Carob genotypes was detected by RAPD analysis. Twenty eight out of 53 bands detected were polymorphic for the different genotypes. Six RAPD specific markers distinguish genotype 5 followed by genotype 4 (four markers) and both genotypes 1 and 3 showed only two specific markers.

Improving Pomegranate Fruit Quality by Using Some Practices
THIS investigation was carried out during two successive seasons of 2013 and 2014 in a private farm located at the 64 Km on the Cairo-Alexandria Desert Road. Pomegranate trees (Wonderful cultivar) were selected to study the effect of two covering materials (white shaded net for trees and white agril bags for fruits) and potassium fertilization (K2SO4) on reducing pomegranate fruit disorders and improving fruit quality. The covering treatments started (after 21 days of fruit set till the 1st week of October) and K2SO4 as soil application at three rates (1.0, 0.75 and 0.50 kg /tree) divided monthly on batches (from March to September). The obtained results showed that, covering trees with white shaded net and supplemented with the application of 0.75 kg/tree K2SO4, increased fruit length (cm), fruit diameter (cm), fruit weight (g) and fruit volume (cm)3. While, the rate of 1.0 kg/tree increased T.S.S %, T.S.S. acidity and vitamin C. The open field trees that fertilized with 1.0 kg of K2SO4 increased yield/tree (kg) and fruit edible part (%). There were convergence between the two rates of K2SO4 (1.0 & 0.75 kg/tree) in total sugars percentage and total anthocyanin content in fruit juice. The highest marketable fruits (%) and the lowest cracked fruits (%), sunburned fruits (%) per tree and fruit juice acidity (%) associated with covered trees with shaded net and fruits with agril bags and have been supplied with 1.0&0.75 kg/tree of K2SO4. Moreover, leaves N, P, and K contents increased by increasing the rates of K2SO4 fertilization, the maximum records were obtained with the open field treatments.
Generally, it can be recommended under the same conditions of this study that, covering pomegranate trees by white shaded net with the addition of K2SO4 at 0.75 kg/tree can be used in reducing fruit disorders and improving fruit quality, that led to increase the total income per fed, this in turn increased the net profit /fed. Increasing the benefit is nowadays used in the main areas of fruit production in Egypt.

Increasing Storability of Mango cv. ‘Zibda’ Fruits By 1-Methylcyclopropene and Gibberellic Acid Postharvest Applications
The effects of postharvest applications of 1-methylcyclopropene (1-MCP) and gibberellic acid (GA3) on fruit quality of stored mango cv. ‘Zibda’ at 13°C were studied during two successive seasons, 2014 and 2015. Fruits divided into three equal groups and treated with 0, 1 and 1.5 ppm of 1-MCP. Applications were performed by placing each group into a hermetic chamber and exposing them to the gas for 24 hours at room temperature. After the duration of 1-MCP applications, the fruits in each group divided into three equal subgroups and mangoes were dipped into aqueous solutions of GA3 at 0, 50 and 100 ppm concentration for ten minutes. All treatments were stored at 13°C for five weeks. All postharvest applications significantly increased fruit storability and reduced the deterioration rate of mango fruits during storage. Moreover, the combination treatments of 1-MCP with GA3 were more effective in this aspect. This experiment revealed that, postharvest application of ‘Zibda’ mango fruits with exposed to 1-MCP for 24 hours or dipped in GA3 solution for ten minutes especially combined treatments before storage at 13°C alleviated decay incidence reduced weight loss percentage and increased marketable fruit percentage. In addition, these applications delayed the variability of fruit colour, decreased loss of fruit firmness and maintained inner fruit quality for up to five weeks at 13°C followed by three days shelf life at room temperature.

Influence of Modified Atmosphere Packaging and Cold Storage on Antioxidants Activity and Storability of Peach Fruit
PHYSICO-CHEMICAL responses and antioxidants activity of …..peach fruit (Prunus persica, L.) cv. "Succary" stored at modified atmosphere packaging (MAP) using shrink film at room temperature (25°C) and cold storage (6°C) were investigated. Results indicated that the individual treatment with MAP or cold storage was found insufficient to delay ripening and to maintain quality for long period. The combination of MAP and cold storage (MAP+6°C) was an effective technique to delay fruit ripening and to extend storage period up to 31 days throughout a reduction in fruit weight loss, fruit softening and membrane damage, in addition to maintaining the activity of antioxidant enzymes )catalase, peroxidase and superoxide dismutase) at a high level.

Evaluation of Some Pecan Varieties Growing under Drip Irrigation System at El-Behera Governorate, Egypt Environmental Condition
FIVE PECAN (Carya illinoensis Wang. R koch) varieties ….namely: Wichita, Desirable, Burkett, Grazona and Mahan were evaluated in a private farmat EL-Behera governorate, Egypt. All data was used to compare the results of morphological parameters, flowering characteristics, dichogamy phenomenon, fruit set, yield, fruit quality, nut shape, moisture and kernel oil content and biochemical genetic finger print.
The results showed that, Wichita, Grazona and Desirable pecan varieties surpassed the others in morphological growth. Mahan vr. be preferred as it produced the maximum No. of vegetative and female buds with longer male and female inflorescences. While, Wichita has higher No. of dormant, vegetative, male and female buds with longer staminate inflorescences. This study exhibited relatively incomplete dichogamy where Desirable, Grazona and Burkett vrs. were classified as protandrous (type,1) while Mahan vr. was classified as protogynous (type, 2). Desirabie can be a good pollinator for both Burkett and Mahan vrs. . There were more consistent periods of overlap between Desirable and Burkett vrs. which reflected on producing higher fruit set. Mahan was the earliest in fruit set followed by Burkett while, Grazona was the latest. Desirable gained higher nut yield in the 1st season while, Wichita has the highest nut yield in the 2nd season. Mahan vr. has the heaviest nut, and kernel weight and oil content followed by Wichita but Desirable and Burkett have the least weight. Palmetic acid was the main saturated fatty acid while, oleic and linoleic acids were the main unsaturated acids. Mahan kernel oil was the richest in palmetic acid during the two studied seasons and linoleic in the 2nd season but the least oleic acid in the 1st one. Wichita oil has the highest oleic acid in the two studied seasons and linoleic acid in the 1st season.
The genetic polymorphism between the five pecan cultivars was detected by RAPD analysis. Sixteen out of 31 bands detected were polymorphic for the different cultivars. Six markers were found to be specific for Mahan, two markers were specific for Wichita and only one specific marker detected for both Burkett and Desirable.
So we can recommend for Egyptian growers to spread the present five pecan varieties all over the new reclaimed soil for enriching Egyptian food, dietary source of antioxidants, raised local market and export.

Effect of Some Organic Compounds and Cluster Thinning on Quality Characteristics and Powdery Mildew of Flame Seedless
THE APPLICATION of some organic materials, Jojoba oil, Neem oil and micronized sulfur, sprayed alone or accompanied with cluster thinning was studied on Flame Seedless grapevine. The experiment was conducted in the 2013 season and extended for two successive seasons. It comprised eight treatments to improve berry quality and limiting the powdery mildew progression. Results indicated that spaying with Jojoba oil, Neem oil had a negative effect on the propagation of Powdery Mildew ‘Uncinulla necator’similar to micronized sulfur and they could be a valid alternative control. Jojoba oil plus cluster thinning treatment was the most effective in stimulating all growth characters and increasing significantly the TSS% and anthocyanin but it lowered the yield than the Jojoba oil treatment. Yield compensation was achieved by an increase in cluster weight of about 53%, in response to a reduction of 33%, in cluster numbers. Neem oil had no significant effect on chemical composition but significantly increased yield by 43% by lowering the number of infected berries per cluster.

Efficacy of Foliar Applications of Salicylic Acid, Zinc and Potassium on Reducing Fruit Drop, Yield Improvement and Quality of Balady Mandarins
THE OBJECTIVE of the present study was to evaluate the effects of Salicylic acid (SA), Zinc (Zn) and Potassium (K) on reducing fruit drop and improving fruit quality of Balady mandarin (C. reticulata, Blanco) at flowering initiation, fruit sized 5 mm and at pre-coloring stage. The experiment was conducted in a commercial orchard in Sharnoob, Behera governorate where 30-year- old trees budded on sour orange rootstock were sprayed with SA at 10mg/L, zinc sulfate at 0.02% and potassium sulfate at 0.25% separately or in combinations. The results showed that K applications alone or combined with SA led to the best results regarding the yield evidenced as fruit number or by weight resulting from markedly increased fruit retention after June drop and final fruit retention percentages. The latter treatment was statistically superior in increasing fruit set followed by Zn or SA solely. All treatments reduced fruit drop, SA separately or plus K or Zn reduced fruit drop than the control treatments. No definite results were obtained concerning fruit physical properties i.e. weight of fruit or peel, fruit length and diameter. However, Zn and Zn plus SA applications significantly increased TSS and TSS/acid ratio, as well as K treatments increased TSS and V.C. as compared to control. Lastly, K or Zn treatments and their combinations with SA resulted in considerable higher values in leaf k and Zn content.

Effect of Foliar Application of Cytokinin, Active Dry Yeast and Potassium on Fruit Size, Yield, Fruit Quality and Leaf Mineral Composition of Valencia Orange Trees
A FIELD experiment was conducted during two successive seasons of 2013/2014 and 2014/2015 in a private orchard located at Sharnoob village, El-Behera governorate, Egypt, this study aim to evaluate the effect of foliar application of benzyladenine, yeast extract and potassium solution on yield, fruit quality and leaf mineral content of Valencia orange trees (Citrus sinensis, osbeck) about 50 years old budded on sour orange (C. aurantium, L) rootstock planted in clay soil. The obtained results proved that spraying trees with a mixture of (BA 40 ppm+ yeast 0.4% + K 0.4%) resulted in a higher number of fruit set/branch, although it caused an increase of fruit juice acidity compared with the control and the differences were significant during both seasons of the study. Also, this treatment, significantly increased fruit length and diameter, only in one season. Moreover, benzyladenine spray treatment at 40 ppm, in both seasons, produced the highest number of fruits/tree, an average fruit weight and yield and participated with potassium at either 0.2 or 0.4% to improve fruit shape (fruits were more circular in shape). In most cases, BA 40ppm spraying treatment markedly increased fruit length, and fruit growth rate comparing to control treatment. The data also revealed that Valencia orange trees sprayed with a combination of (BA 20ppm + yeast 0.2% +K 0.2%), in both seasons, gave significantly higher fruit diameter and fruit growth rate in most measuring dates, increased vitamin C content in the fruit juice. Trees sprayed with dry yeast extract at 0.2%, in both seasons, markedly increased total soluble solid percentages in fruit juice. In addition, potassium spray treatment at 0.4% markedly increased fruit diameter, only in one season and participated with benzyladenine at 40ppm and dry yeast extract at 0.2% to improve fruit physical properties (length, diameter, pulp and rind weights, fruit weight and juice volume). Different foliar application increased total nitrogen, phosphorus and potassium in the leaves. Trees sprayed with a mixture of (BA 20ppm+ yeast 0.2%+ K 0.2%) and 0.4% potassium solution treatment, in both seasons, significantly increased leaf total nitrogen content as well as potassium spray treatments at either 0.2% or 0.4%, markedly increased leaf phosphorus and potassium content.

Recurrent Selection and Selfing with Selection as a Tools for Improvement of Sweet melon (Cucumis melo var. aegyptiacus)
THE PRESENT investigation was carried out during three ……..successive summer seasons of 2012, 2013 & 2014, in order to study the efficiency of one cycle of simple recurrent selection and selfing with selection for two generations as two breeding methods on some important characters of sweet melon. Coefficient of variation (C.V%) for the characters, main stem length, leaves number/plant, branches number/plant, fruit weight, fruit polar diameter, fruit equatorial diameter, fruit number plant-1, fruit flesh thickness, and total soluble solids, were estimated. In a relatively large population of cultivar "Kahera-6" of sweet melon reflected, generally, enough variability for the purposes of selection and improvement. Generally, the results indicated that all the studied characters were improved through the two practiced breeding methods, simple recurrent selection and selfing with selection, but with different magnitudes among the characters and the used breeding methods. Variability magnitudes within the studied characters were declined as a result of practicing the two breeding systems, but with more severe reduction in the second selfed progenies, relative to the simple recurrent selection population. The estimated values of the correlation coefficients among the various pairs of the studied characters illustrated generally that twenty two out of the possible thirty six relationships appeared to be significant and desirable for the objectives of selection in the present study.

Sweet Corn as Affected by Foliar Application with Amino – and Humic Acids under Different Fertilizer Sources
TWO FIELD experiments were conducted at the Experimental …….Station Farm (at Abies), Faculty of Agriculture, Alexandria University, Egypt, during the two summer seasons of 2014 and 2015. The objective of this investigation was to study the main effects of three different fertilizer sources as well as control (20 m3fed-1 chicken manure, 30 m3fed-1 cattle manure and 100 – 40 – 60 kg NPK fed-1, as recommended rates from each one of the three sources of fertilizer), foliar spray using two sources of growth stimulants as well as the control (spray with distilled water), (2 g L-1 amino acid and 2.5 ml L-1 humic acid), and their interaction on growth, yield and its component characters, and some chemical composition of kernels and leaves of sweet corn. The obtained results indicated that the application of chicken manure to sweet corn plants increased the most measured vegetative and kernels quality ( plant height, leaves number plant-1, kernels dry matter, reducing sugars, total sugars, T.S.S.), while, the application of either chicken manure or cattle manure, significantly, increased sweet corn yield, ears characteristics and NPK leaves content. Regarding the effect of foliar spray by amino – and humic acids, the results pointed out that the application of amino acid foliar spray were significantly associated with corresponding increases in the most important characters of sweet corn plants. The results concerning of the first order – interaction indicated that the application of chicken – or cattle manure fertilizer combined with the foliar spray with amino – or humic acids, resulted in the highest mean values of the vegetative growth characters, and most of the studied yield and its components characters. The most favorable combination treatment was chicken manure combined with amino acid foliar spray, which gave the highest mean values for the most previous studied characters.
