The present study was conducted during 2008 and 2009 seasons on fifteen olive cultivars as a source of cuttings and planted in the experimental orchard of Horticultural Research Station, Seds, Beni- Suef Governorate, Egypt. The cultivars namely: Aggizi Aksi, Aggizi Shami, Arbequin, Coratina, Dolce Frantoio, Hamed, Kalamata, Koroneiki, Manzanillo, Maraki, Nabali Mohassan, Picual, Toffahi and Wardan. The cuttings were planted under a white plastic tunnel inside a shaded net house. This study included the two experiments: Experiment (1): The aim of this experiment was to study rooting ability parameters of the fifteen olive cultivars under study, the results showed that, cuttings of Manzanillo, Picual, Aggizi Shami, Aggizi Aksi, Koroneiki and Coratina gave the highest values of most of the studied rooting parameters as, rooting percentage, number of roots and total roots length. Experiment (2): The main objective was to study the effect of time of cutting preparation dates (February, May, August and November) of three olive cultivars (Coratina, Kalamata and Manzanillo) as well as interaction effect of their combinations on rooting ability parameters. Cuttings of Manzanillo cv. had good rooting characters 66.25 & 66.14 followed by Coratina cv. 62.39 & 59.91 then Kalamata cv. 12.52 & 10.81 during 2008 & 2009 seasons. August and November were considered the best date of cutting preparation under the same conditions of this study. Cuttings of Manzanillo prepared at August gave the highest rooting percent .The highest survival percentage after two months from transplanting was recorded from cuttings prepared and planted at August and November in both studied seasons. As a conclusion we can say that rooting of some olive cuttings under shaded Polyethylene tunnel consider the best method compared with the other methods because it do not need a very expensive equipments.

Two sugar industrial by-products, cane bagasse “SCB” and sugar beet molasses “SBM” along with two fructan storing crops ,chicory roots“CR” and Jerusalem artichoke tubers “JA”, alone or after mixing were utilized as a carbon source in fermentation medium to produce citric acid by Aspergillus niger strainGQ890276. It was found that the proximate composition and total sugars content of these agro-materials played a role in terms of citric acid production . Moisture ranged from 6.55 to 23.15%; crude fat from zero to 1.55%; crude protein from 3.27 to 8.53%; crude fiber from zero to 47.46% , ash from3.29 to 8.93% ,nitrogen free extract from 44.83 to 87.06 % and total sugar 8.11 to 87.06% among these materials. The fermentation media either containing mixture of CR +SCB and/or CR as carbon source gave high citric acid yield after 7 days of fermentation comparing with other used carbon sources. The citric acid yield was 59.36 g/L in CR +SCB medium .It was 87.80% when calculation was based on the amount of consumed fermentable sugars. Also this media gave the high biomass ( 22.90 g/L)yield.

The present work was conducted in the Experimental Farm of the Faculty of Agriculture in Shebin El-Kom to study seasonal population dynamics of Parlatoria ziziphus (Lucas). During the present investigation it was observed that it is often difficult to remove the scales of this insect especially as alive adult females from the citrus infested leaves. It was observed also, that the average numbers on upper surface of leaf were more abundant than that on lower surface. Three annual peaks of abundance were encountered and recorded through both years of study (2008/2009 and 2009/2010) during April (in spring season), October (in autumn season) and December (in winter season). The highest one occurred in October in both years. Thus, the present results may help in planning a successful control program to check the ravages of P. ziziphus below economic injury level.

A pot experiment was carried out in a greenhouse at the Faculty of Agriculture (Saba-Basha)-Alexandria University in order to evaluate the effect of two species of mycorrhizae (Glomus intraradiaces (M1) and Glomus macrocarpium (M2)), two genera of bacteria (Bacillus subtilis (B1)and Pseudomonas fluorescens (B2)) and two genera of yeast (Cryptocooccus neoformans(Y1)and Candida albicans (Y2)) as a biological control of white mold of bean disease (Phaseolus vulgaris L. with two varieties Bronco and Contender ) which infected by Sclerotinia sclerotiorum. Two isolates of Sclerotinia sclerotiorum (S4 and S6) were selected. The results of this study suggested that the difference microorganisms which used as bioagents especially AMF first specie (Glomus intraradiaces) was sufficient to inhibit the Sclerotinia isolates. On the other hand, Contender common bean variety was more sufficient than the other variety (Bronco). Also, the first isolate of Sclerotinia (S4) was less dangerous compared with the other isolate (S6). In future studies, the interaction between the bioagents and the host plant are needed to develop much more efficient biological control agents of the related diseases.

The fungus Stachybotrys chartarum was isolated from Orobanche seeds, which were collected from different localities of the Nile Delta, Egypt. In pot trials, mycelial suspension, as well as, the fungal filtrate completely prevent the attack of O.crenata to faba bean (Vicia faba) with. Also, fungal filtrate completely inhibited the germination of O.crenata and O.ramosa seeds induced by the synthetic germination stimulant GR24. Such effect was attributed to the presence of mycotoxin(s) secreted by the fungus.

Toxicity of some insecticides against egg masses and two larval instars of cotton leafworm (CLW), Spodoptera littoralis, field and laboratory strains was determined. The activities of glutathione S-transferases (GST) and alkaline phosphatases (ALP) in the two strains also were compared. Results revealed that, spinosad, spinetoram, emamectin benzoate and lufenuron have low ovicidal activity. Chlorpyrifos and methomyl at 10 ppm achieved 80.4 and 83.6% mortality of treated egg masses, respectively. On the other hand, spinosad, spinetoram and emamectin benzoate at the same concentration caused 18.9, 19.4 and 28.1% mortality of treated egg masses, respectively. While lufenuron at 25 ppm caused 54.9% mortality of treated egg masses, lufenuron at 100 ppm achieved 100% mortality of treated egg masses at 100 ppm. Although spinosad, spinetoram and emamectin benzoate have low ovicidal activity compared with methomyl and chlorpyrifos, they have a comparable residual toxicity with methomyl and chlorpyrifos against the neonates. The residual toxicity of lufenuron against neonates is low at all tested concentrations. The 2nd and 4th instar larvae of the field strain exerts high resistance levels towards methomyl, chlorpyrifos and esfenvalerate. Regarding the 2nd instar, resistance ratios in 2008 and 2009 cotton seasons were 43.9 and 50.8 towards methomyl, 27.6 and 24.7 towards chlorpyrifos and 76.4 and 79.2 towards esfenvalerate. For the 4th instar resistance ratios in 2008 and 2009 cotton seasons were 62.8 and 63.6 towards methomyl, 43.9 and 49.2 towards chlorpyrifos and 112.4 and 114.8 towards esfenvalerate. On the other hand, field strain shows low or no levels of tolerance to spinosad, spinetoram, emamectin benzoate, lufenuron and methoxyfenozide. Activities of GST and ALP in the field strain were higher compared with that in the laboratory strain. In conclusion, the alternation between these insecticides can avoid increasing selection pressure of CLW populations to these insecticides.

This study was carried out to evaluate the biological effects of two IGRs (Match® and Baycidal®) on Culex pipiens mosquitoes when fed the adults on sugar solution mixed with 0.1, 0.5 and 1 ppm of each compound. Some delayed effects of these treatments were also determined. The results indicated that the use of each of the tested IGRs caused a reduction in the blood-feeding activity of mosquito female when compared with the controls. The reductions were 18.2, 22.7 and 31.8% by using Match and 25, 27.3 and 36.3% by using Baycidal®, respectively, at the tested concentrations. The reduction in biting activity of mosquito females may lead to a decrease in the number of fully engorged females and accordingly affect their reproductive capacity of mosquitoes. The use of Match® and Baycidal® at the tested concentrations caused a marked prolongation in the time needed for blood meal digestion by C. pipiens females. The prolongation percentages were 44.4, 48,8 and 55.5% by using Match and 51.1, 55.5 and 62.2% by using Baycidal®, respectively. Also, treatments caused a reduction in the reproductive capacity. The maximum decreasing in egg production was 30.3% at concentration of 1 ppm of Match®. The result showed that the treatment by Baycidal® at 0.1, 0.5 and 1ppm led to a remarkable reduction in the egg production by 61.9, 66.1 and 69.2%, respectively and also the hatchability was reduced in the treated females. Subsequent study was carried out to investigate the delayed effect of IGRs Match® and Baycidal® on the hatched larvae. The result showed that the larval development was gradually inhibited by 17.8, 49.8 and 92.7% by using Match® at 0.1, 0.5 and 1 ppm, respectively. On the other hand the larval development was completely inhibited after the treatment of adults fed by 0.5 and 1 ppm Baycidal®. The larvae developed till the 2nd instar but completely failed in molting to the 3rd instar. Subsequent study was conduced on the effect of Match® and Baycidal® on the longevity of the survived mosquito adults that, the records showed that no significant differences in the mean of adult longevity between treatments and control.

The maximum decreasing in egg production was 30.3% at concentration of 1 ppm of Match®. The result showed that the treatment by Baycidal® at 0.1, 0.5 and 1ppm led to a remarkable reduction in the egg production by 61.9, 66.1 and 69.2%, respectively and also the hatchability was reduced in the treated females. Subsequent study was carried out to investigate the delayed effect of IGRs Match® and Baycidal® on the hatched larvae. The result showed that the larval development was gradually inhibited by 17.8, 49.8 and 92.7% by using Match® at 0.1, 0.5 and 1 ppm, respectively. On the other hand the larval development was completely inhibited after the treatment of adults fed by 0.5 and 1 ppm Baycidal®. The larvae developed till the 2nd instar but completely failed in molting to the 3rd instar. Subsequent study was conduced on the effect of Match® and Baycidal® on the longevity of the survived mosquito adults that, the records showed that no significant differences in the mean of adult longevity between treatments and control.

Powders of the aerial parts of thirteen Saudi wild plant species namely: Achillea fragrantissima, Anastatica hierochuntica, Brassica sinaica, Calotropis procera, Cleome rupicola, Ducrosia anethifolia, Fagonia bruguieri, Lactuca serriola, Pulicaria crispa, Reseda muricata, Salsola imbricata, Trichodesma africanum and Zygophyllum migahidii were screened for their nematicidal activity towards the root-knot nematode(Meloidogyne javanica) infecting common bean cv. Strike in a pot experiment under greenhouse conditions (35±5ºC). Plant powders were applied as amendments of nematode-infested soil at 0.3% (w/w), comparing to a treatment with the nematicide, Carbofuran 10%G (0.1g/pot), 7 days prior to planting. Nematode-free soil and nematode-infested soil were served as checks. All studied plant powders significantly reduced (P≤0.05) numbers of root galls, nematode egg masses, final nematode egg populations and reproduction factor on common beans, as compared to nematode check. Among them, C. rupicola, S. imbricata, T. africanum and Z. migahidii provided the maximum reductions of all disease parameters ranged from 82.0-96.4%, whereas F. bruguieri gave the minimum ones (33.9-40.4%). Meanwhile, application of Carbofuran 10% resulted in 88.0-90.8% reduction of all disease parameters. On the other hand, common bean growth of the most treatments significantly increased (P≤0.05), as compared to nematode check plants, and mostly to the nematicide-treated and healthy ones. Percentages of increase were ranged from 80.1 - 188.3% in shoots and 106.8 - 278.8% in roots. On the contrary, soil treatments with the powder of A. hierochuntica and Z. migahidii, showed little phytotoxicity symptoms on common beans. Powders of C. rupicola, S. imbricata, T. africanum and Z. migahidii achieved relative nematicidal efficacy ranged from 66.5 – 269.1% of Carbofuran 10%. The current results recorded new wild plants in Saudi Arabia with a potential nematicidal activity against the root-knot nematode. They may be considering a safe source of new alternative nematicides.

This study was carried out during two successive seasons of 2008/2009 (Mother plants) and 2009/2010 (First ratoon) of GrandNain banana grown in the newly reclaimed sandy soil (an orchard located at Kafr Daoud), MonofiaGovernorate, Egypt. The vegetative growth, flowering, fruiting and yield of GrandNain banana grown under six planting distances, a range of within row spacing, giving population densities of (933 to 1400 plants/fed.), were studied. The data revealed that the banana plants at close spacing had taller pseudostem than plants under wide spacing. The plants which were at 3x3 m as 2 plants per hole gave higher values of plant circumference, number of green leaves at bunch shooting and total leaves/plant. Earliest shooting and minimum days for harvesting were recorded at wider spacing at 3x4 m and bunches emerged earlier (10-15 days) than bunches from plants spaced at 3x1 m during the two studied seasons. Heaviest bunches were produced from plants at 3x4 m spacing and three plants per hole. Spacing at 3x2 m and 2 plants per hole gave the highest yield (23.8 and 32.34 ton/fed) during the mother plants and first ratoon, respectively. The increase in yield by this planting distance could be attributed mainly to the increase in number of plants per unit area. The biggest fingers ( weight, length and diameter) were produced from plants spaced at 3x3m. orded new wild plants in Saudi Arabia with a potential nematicidal activity against the root-knot nematode. They may be considering a safe source of new alternative nematicides.

The agricultural cooperatives play a central role in Egyptian economy, through the cooperatives roles on community development, production services, subsidized agricultural inputs, technical support, financial responsibilities and social activities. Accordingly the study aims to identifying the socioeconomic determinants of the performance of the new lands cooperatives. The study is applying the multidimensional ILO/DANIDA scale of cooperative performance including the community development, facilitating social services, productive investment, agricultural inputs, minimizing the production cost, technical support, resources protecting, training and logistics and communication. Using he socioeconomic variables: goal attainment, self reliant ratio, marketing, annual sales, technical support, finance, training and communication. The study was carried out on four villages at El-Behira governorate (Alghomhoria, New Edko, El-horrya and Nasser villages), and data were collected by personal interviews using a pre tested questionnaire from 155 cooperative members using a random systematic sample. The questionnaire was coded and data were statistically analyzed applying the simple correlation and multiple linear regression techniques. The participation on cooperative activities alone explains about 17% of the variance in the cooperative performance and the values of collective work variable explains about 9% of the variance of cooperative’s performance, the marketing opportunities explains about 4% of the variance in the dependent variable and the finance of productive projects variable explains about 3% % of the variance of cooperatives performance. The results were conceptualized around applied linkage that connects four practical fields; encouraging member participation, activating the values of collective work, the marketing of commercializing products and the financial support to the agricultural projects

Apple orchard cv. Anna/MM106 rootstock planted in 2003 at 4 x 3 m at Al- Nubaria , Behira governorate, were treated during 2009 and 2010 seasons in the inter-row spaces by: 1) check – plots, CP (Control); 2) black polyethylene film, BPF (from the tree trunk to the tree canopy, 0.12 mm thick applied from February to October each season); 3) white polyethylene film, WPF (from the tree trunk to the tree canopy, 0.12 mm thick applied from February to October each season); 4) mulching with Alfalfa straw, MAS; 5) mulching with Rice straw, MRS and 6) compost of organic matter, COM (15m3/Fed.) applied once at December. Trees were planted in a sandy loam with a pH of 7.6 and irrigation was drip system. Results indicated that, all plastic mulch coverings treatments (BPF and WPF) and applied compost of organic matter (COM) showed an increment in soil temperature and soil moisture content in both seasons as compared with control treatment. Moreover, plastic films around the trees gave the highest increment in shoot length, number of leaves/shoot and leaf area followed by mulching with alfalfa or rice coverings soil treatments as compared with check plot treatment, while the compost organic matter treatment gave the lowest value in both experimental seasons. Also, all mulching treatments with plastic films, covering crops, as well as, compost organic matter caused an increased fruit weight (g), tree yield (Kg), fruit length, fruit diameter and fruit firmness as compared with check plot treatment in both seasons. Fruit color percentages had greater light intensity at all polyethylene films applications than light reflected from the other covering crops, compost organic matter and untreated trees. The same trend was found for anthocyanin contents in fruits at both seasons. Concerning the TSS % and acidity %, results showed that mulching treatments either with polyethylene or cover crops decreased the two parameters comparing with control treatment in both seasons, while the reverse was true for starch and total sugar contents. Moreover, the applied treatments increased significantly leaf and fruit N, P, K, Fe, Zn and Mn contents as compared with the control treatment in both seasons.

The present study was carried out at a private orchard at El-Akrisha Kafr El-Dawar district, Behera Governorate, Egypt, on eight years old "Anna" apple trees (Malus domestica, Bork) buded on Balady rootstock during the 2008/2009 and 2009/2010 growing seasons under surface irrigation system. This investigation aimed to study the response of Anna apple trees to organic amendment type (cattle (M1) and horse (M2) manures) with rate of 25 kg/tree/year (20 m3/fed/year), with two different types of potassium fertilizers (K2SO4 (SOP) & KCl (MOP) with three levels from each type (0,50 and 100kg K2O /fed/year). The results indicated that horse manure (M2) was more effective than cattle manure in improving the measured parameters (number of leaves/shoot, leaf area, number of flowers/ cluster, fruit set%, fruit weight, fruit length, fruit diameter as well as yield, anthocyanine %, starch%, TSS%, average fruit firmness (lb/inch2), total sugars%, acidity% and leaf NPK content). The data clarified that increasing the rate of potassium significantly increased all tested parameters for the two types of potassium fertilizers compared with control (zeroK2O). On the other hand, potassium chloride gave the best results to improve the studied characters compared with potassium sulfate. The results also indicated that the best treatment was when fertilizing Anna apple trees with horse or cattle manure with rate 20 m3/fed/year and applying 100 kg K2O (K2SO4 or KCl). The yield of these treatments reached 21 and 17 ton/fed for horse and cattle manure, respectively compared with control (11 ton/year). mso-bidi-language:AR-EG'> Fruit color percentages had greater light intensity at all polyethylene films applications than light reflected from the other covering crops, compost organic matter and untreated trees.

Response of cabbage plantsto different rates of chicken manure (00, 10 and 20 m³/fed.), levels of mineral N (00, 60 and 120 kg N/fed. as ammonium nitrate) and humic acid foliar treatments (0, 1 and 2 g/l) as well as their interactions was studied at the Experimental Station Farm, Faculty of Agriculture, Alexandria University during two growing seasons of 2007/2008 and 2008/2009. The obtained results indicated that application of 20 m3/fed. of chicken manure showed more superior effect on vegetative growth characters (plant weight, non wrapper leaves weight and number, as well as total head yield and its component (net head weight, head length and diameter), and N content of inner edible leaves. Addition of 120 kg N/fed. mineral N fertilizer increased plant weight, head weight, head diameter and total head yield; increased N content and decreased total sugar content of inner leaves. Foliar application of humic acid improved plant weight, stem diameter, total head yield and its component (head- weight, length and diameter). Nitrogen content of inner edible leaves was also increased while total sugar content was decreased. Application of the highest rate of chicken manure (20 m3/fed.) combined with the highest level of mineral N (120 kg N/fed.) or humic acid (2 g/l) was found to be favorable for the cabbage to express their best performance on plant weight, net head weight and total head yield. In general, the obtained results reflected high response of cabbage plants cv. "Brunswick" for fertilization with organic and mineral N fertilizers with humic acid, reflected as promoted plant growth and increased head yield and quality under the conditions of the present study.

The effects of six combinations of NPK fertigation (100N+20P+100K(T1),125N+30P+130K(T2),150N+40P+160K(T3),175N+50P+190K(T4),200N+60P+220K (T5) and 225N+70P+250K(T^) ppm) at 3 days interval on plant growth and flowering in two rose cultivars: Red Giant and Sunflare were investigated. Plant height, number of branches per plant, number of leaves per plant, flowering time, number of flowers per plant and number of petals per flower were maximum with fertigation at 175N+50P+190K ppm.
All other combinations above this level of NPK produced more or less statistically similar results hence are not recommended as economical one. NPK fertigation combinations below 175N+50P+190K ppm level were statistically produced inferior plant growth characteristics hence not recommended as ideal ones.
