The study showed that the use of the magnetic field has positive effects on seed germination and plant growth of tomato, it has been shown that the best ratio of vitality and germination of seeds appeared when exposing the seeds for 8 minutes to a magnetic field strongly in 1800 chaos where it was tested several periods of exposure 0, 2, 4, 8 and 16 minutes reaching 83, 100, 90 , 93, 100, 93 and 83 %, respectively, compared with the control treatment, which amounted to (80 %) study also demonstrated the best combination of organic fertilizer in terms of quantity and quality, which included two types of compost and are remnants of rice and remnants of wheat where outperformed the treatment of manure waste 1 : 1 on all transactions where the total length and weight Bared 28.The conditions in the plastic house has achieved treatment F.o.l.

+ Salicylic acid + P.

fluorescens for the dry weight of the root system and vegetative 0.16 g and g 0.5, and the treatment of P.fluorescens amounted to 0.22 g and 0.3 g, respectively, amounted to treatment comparison 0.5 and 0.20, respectively, as varied all transactions significantly compared to the treatment of F.o.l.

(plants inoculated with pathogen only) where achieved a 0.5 and 0.15, respectively.

The results of laboratory experiments reinforced the results of the experiments the plastic house and confirmed the effectiveness of different treatments, as it showed the treatment of yeast S.cereveciae highly efficient in encouraging recorded for the dry weight of the root system and vegetative 0.35 and 1.5 g have varied significantly for the treatment of (F.o.l.) plants inoculated with pathogen only (reaching 0.5 and 0.15 g .

has also led transactions factors resistance vital in improving the rates of some indicators of output (number of inflorescences per plant and the percentage of the contract and fruit weight and the amount of winning), as well as some signs of vegetative growth (dry weight of shoots and roots and the number of forest / plant).
