Thirty-eight isolates of fungi belonging to genera Rhizoctonia, Fusarium and Macrophomina were isolated from diseased faba bean plants, collected from different localities in New Valley governorate, showing root rot and wilt symptoms. The isolates proved to be pathogenic on Masr 1 faba bean cultivar under greenhouse conditions. R. solani, F. solani, M. phaseolina and Fusarium spp. isolates caused root rot diseases; however, isolates of F. oxysporum caused wilt. The virulence of isolates on the tested faba bean cultivar was varied. The highly pathogenic isolates of these fungi were employed in this study. The effect of magnetized tap water (MTW), magnetized agricultural drainage water (MADW) and magnetized seeds (MS) on the severity of root rot caused by R. solani, F. solani and M. phaseolina and wilt diseases caused by F. oxysporum of faba bean was tested under greenhouse and field conditions as well as its effect on plant growth and yield components in the field. The obtained data indicated that faba bean plants derived from (MS) then irrigated with magnetized water, either tap or agricultural drainage water recorded the lowest root rot and wilt severity under artificial soil infestation with any of the tested fungi and/or natural infection in the field compared with non-magnetized seeds (NMS) then irrigated with non-monetized water (NMW), respectively. Plants derived from MS and irrigated with magnetized water (MTW and MADW) gave the highest plant growth parameters (plant height, number of branches/plant) and yield components (number of pods and seeds/plant, weight of 100 seeds and total yield/feddan) compared with those grown from non-magnetized seeds and irrigated with non-magnetized water (tap and agricultural drainage water, respectively). Generally, plants derived from magnetized faba bean seeds and irrigated with magnetized tap water recorded the lowest root rot and wilt severity under greenhouse and field conditions and increased plant growth and yield parameters.

Bamboo plants are an essential element in Egyptian agriculture development. Nothing was found on propagation of Dendrocalamus giganteus under the Egyptian conditions. Thus, two trials were done to evaluate the effect of position of cuttings on the stem, time of propagation, indole-3-butyric acid (IBA) treatments, planting method on rooting of culm and culm-branch cuttings of bamboo under greenhouse conditions. Three cutting types (basal, middle and tip) of single and double nodes were collected from culm (main stem) and culm-branch (lateral branch) cuttings of bamboo during September 2004 and March 2005. Culm-branch cuttings were treated for 24h with IBA at 0, 50, 100 and 200 ppm. Cuttings were planted horizontally and/or vertically in clay soil. The experiments were arranged in Randomized Complete Block Design as split plot with three replicates. The obtained data were statistically analyzed and revealed the following: Culm-cuttings showed better rooting and growth parameters compared to culmbranch cuttings. In general, single-node cuttings of culm and culm-branch were better than the double nodes ones. Both branch types showed the highest rootability at March period of propagation. Meanwhile, September propagation was suitable to culm-branch cuttings only. Treated cuttings of IBA showed markedly improvement its rootability. Basal cuttings contained more C/N ratio than that in tip ones. The best results were obtained from treating basal culm-branch cuttings with 100 ppm IBA. Vertical planting of double nodes cuttings reduced its rootability.

A pot experiment was conducted to investigate the effect of inoculation with Bacillus subtilis and/or Arbuscular Mycorrhizal Fungus (AMF) or maintained as uninoculated controls on the growth, oil %, oil yield and nutrient uptake of three sweet basil cultivars (Local cultivar, Nano Compatt and Red Bordaux) under different salt stress levels (0, 1000, 2000 and 4000 ppm). Results indicated that the high salinity level (4000 ppm) caused significantly reduction in plant height, fresh and dry weights of the herb, number of branches/plant, oil % and oil yield as well as contents of N, P and K in leaves of all studied sweet basil cultivars. Meanwhile, sodium Na+ content in leaves were high, especially at high NaCl concentration. Red Bordaux cultivar was more sensitive to salinity stress than Local and Nano Compatt cultivars. Inoculation with Bacillus subtilis and/or mycorrhizal fungi showed positive effects on growth, oil %, oil yield and nutrient uptake either with or without the salinization treatment. Mycorrhizal colonization showed enerally more pronounced effects than B. subtilis. Dual inoculation with B. subtilis and mycorrhizae provided higher tolerance to salinity compared with the individual treatment. It could be concluded that inoculation of sweet basil cultivars with B. subtilis and mycorrhizal fungi may induce increases in tolerance to salinity of the three tested sweet basil cultivars.

The aim of this study was to investigate the influence of foliar application of Moringa oleifera leaf extracts (control, 2.5% and 5% aqueous MLE, 2.5% and 5% ethanolic MLE) and/or benzyladenine (control, 50, 100 and 200 ppm BA) on the growth, fruit and oil yield and its main components and chemical constituents of fennel (Foeniculum vulgare, Mill.) plants. The obtained results revealed that treated fennel plants with MLE and/or BA resulted in a significant increase in the vegetative growth, number of umbels/plant, fruit and oil yield per plant and feddan as well as total carbohydrates in fruits, chlorophyll a, b and carotenoids, nitrogen, phosphorus and potassium contents in leaves compared to untreated plants. Generally, the application of moringa leaf extracts was more effective than BA treatments. The individual treatment of aqueous MLE at 5% or BA at 100 ppm gave the best results of the previous mentioned characteristics followed by 5% ethanolic MLE or 50 ppm BA compared to the control and the rest of tested individual ones. The highest values of all studied parameters were obtained by using 5% aqueous or ethanolic MLE combined with 100 ppm BA. The increments were 91.1% and 85.3% in fruit yield/feddan, 52.5% and 46.3% in volatile oil percentage and 192.4% and 172.0% in oil yield/feddan, respectively over the control. The G.C. analysis of the volatile oil showed that the major component of volatile oil was methyl chavicol (estragole) with concentration range from 77.5% to 87.3%. The minor compounds were myrcene and limonene. The best treatment for decreasing the concentration of methyl chavicol (77.5%), which is undesirable component in fennel oil resulted from the combination of 5% aqueous MLE plus 100 ppm BA. Therefore, it could be recommended that spraying fennel plants with 5% aqueous MLE plus 100 ppm BA for obtaining higher vegetative growth, fruit and oil yield.
