EFFECT OF COMPOST FERTILIZATION LEVELS ON GROWTH, YIELD AND CHEMICAL COMPOSITION OF SANDY SOIL GROWN AMMI VISNAGA PLANTS
The present investigation was conducted at the nursery of Fac. of Agric., Minia Univ. during the two successive seasons of 2014/2015 and 2015/2016 to explore the most suitable level of compost for Ammi visnaga plants grown in sandy soil.
All studied vegetative growth characters (plant height, branch number and herb dry weight/plant); yield parameters (number of umbels/plant and seed yield per plant and per fed); and chemical constituents (photosynthetic pigments and herb percent and content of N, P and K) were gradually increased parallel to the increase in compost level added to the soil. However, no clear difference was obtained, for all prementioned traits, between the medium compost level (12.5 ton/fed) and the high one (17.5 ton/ fed). In general, seed yield per fed, due to medium or high compost rate was increased by about 30%.

IMPROVEMENT OF YIELD AND QUALITY OF ROSELLE (HIBISCUS SABDARIFFA L.) PLANT BY USING NATURAL SOURCES OF PHOSPHORUS AND POTASSIUM IN CALCAREOUS SANDY SOILS
Two separate field experiments were conducted during 2013 and 2014 to study the effects of natural sources of phosphorus and potassium fertilizers as rock phosphate (RP) and feldspar (F) with or without biofertilizers comparing with chemical fertilizer (PK) on growth, yield and quality characteristics of roselle (Hibiscus sabdariffa L.) plant. The first experiment included phosphorus treatments (at different levels of rock phosphate; 150, 200 and 250 kg/fed) and the second one included potassium treatments (at different levels of feldspar; 250, 350 and 450 kg/fed), each comparing with recommended dose of chemical PK. The obtained results revealed that co-inoculation of PDB (Bacillus megaterium var. phosphaticum) and KDB (Bacillus mucilaginosus) in conjunction with direct application of rock phosphate at rates of 200 and 250 kg/fed and feldspar at rates of 350 and 450 kg/fed respectively, into the soil significantly increased the growth characteristics under the study (plant height, number of branches/plant, fresh and dry weight/plant,) along with yield (number of fruits/plant, fresh weight of fruit/plant, fresh and dry weight of sepals/plant, weight of seeds g/plant and weight of dry sepals kg/fed) comparing to chemical PK and other treatments. The highest growth and yield were obtained from plants treated with 200 kg/fed rock phosphate plus PDB in the first experiment and 350 kg/fed feldspar plus KDB in the second experiment. While PK treatment resulted in the highest acidity % and total anthocyanin content of dry sepals as compared to all the other treatments in the first and second seasons. Generally, the results suggest that the use of biofertilizer with rock phosphate or with feldspar are economical, environmental friendly and have potential to improve roselle yield and quality.

ANTIFUNGAL ACTIVITY OF SOME ESSENTIAL OIL EMULSIONS AND NANOEMULSIONS AGAINST FUSARIUM OXYSPORUM PATHOGEN AFFECTING CUMIN AND GERANIUM PLANTS
In the present investigation, the antifungal activity of essential oil emulsions and nanoemulsions of sweet basil (Ocimum basilicum L.), marjoram (Majorana hortensis Moench), peppermint (Mentha piperita L.), spearmint (Mentha spicata L.) and thyme (Thymus vulgaris L.) were evaluated against Fusarium oxysporum isolated from infested cumin and geranium plants. Essential oils were obtained by hydrodistillation and analyzed by gas chromatography. The nanoemulsion was formulated using the essential oils, non-ionic surfactant (Tween 80) and water by ultrasonication method for 30 min and characterized by particle size analyzer and transmission electron microscope. Essential oil emulsions were prepared as mentioned above without sonication. The transmission electron micrograph showed that the essential oil nanoemulsions were spherical in shape and moderately mono or di-dispersed. The droplet size was correlated well with the results obtained from droplet size analysis showing that droplets are present in the nanometer range, with particle size of less than 100 nm and were stable after 3 months of storage under room temperature (27 °C). Four concentrations of the emulsions and nanoemulsions were used to evaluate the anti-fusarium activity in vitro. The results showed that maximum inhibition against Fusarium oxysporum. f.sp. cumini was resulted by thyme essential oil nanoemulsion and emulsion at 2000 ppm and sweet basil essential oil nanoemulsion at 4000 ppm. Also, maximum inhibition against Fusarium oxysporum isolated from geranium plant resulted by thyme essential oil nanoemulsion and emulsion at 2000 ppm. All essential oil nanoemulsions exhibited higher activities compared to emulsions against fungal growth at all concentrations. Treating cumin seeds with each of the concentrations of essential oil emulsions did not affect germination, while seed germination percentage sharply decreased at high concentrations of nanoemulsions treatments. The results suggest the potential effects of thyme and sweet basil essential oil nanoemulsions as novel fungicide agents against Fusarium spp.

PROPAGATION OF A RARE ORNAMENTAL CLIMBER PLANT PORANA PANICULATA BY TISSUE CULTURE
This work was carried out in the Tissue Culture Laboratory, Horticulture Research Institute, Agricultural Research Center, Giza, Egypt during the period from 2015 to 2017, to investigate some factors affecting propagation of the rare ornamental climber Porana paniculata by tissue culture. Results could be briefed in the following: using clorox at 20% as a sterilant achieved the highest position in survival % and the lowest one concerning contamination %. The highest position was also occupied by clorox at 5% in relation to contamination %. Exposing explants to clorox for either 15 or 20 min gave rise to the highest survival %. Explants exposed to clorox at 20% for 15 min obtained the highest position in survival %, the pre-lowest rank in contamination % and the lowest one regarding mortality %.
Using BAP at 0.60 ppm gave rise to the highest position in lateral buds survival %, regeneration capacity, culture efficiency, shoot number, shoot length and leaf number. Using 1/2 MS media induced the 1st position concerning lateral buds survival %, regeneration capacity, culture efficiency, shoot number, shoot length and leaf number. Using BAP at 0.60 ppm + 1/2 MS medium resulted in the highest records of lateral buds survival %, regeneration capacity, culture efficiency, shoot number, shoot length and leaf number. BAP at 0.40 ppm + 1/2 MS medium gave the 1st rank of shoot number. Using BAP at 1 ppm induced the 1st position regarding shoot survival %, shoot number, shoot length and leaf number. NAA at 0.1 ppm resulted in the 1st position regarding shoot survival %, shoot number, shoot length and leaf number. BAP at 1 ppm + NAA at 0.1 ppm recorded the 1st position concerning shoot survival %, shoot number, shoot length and leaf number.
