The obtained benzimidazoles' series were fully characterized and exhibited remarkable pharmacological activity upon in vitro screening for their antibacterial activity against strains of selected pathogenic Gram-positive bacteria (Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli) comparing with Ampicillin and Kanamycin as standard antibacterial agents and against human liver cancer cell lines (HepG2) as antitumor agents as well.

Two field trials on wheat (Triticum aestivum L.; Variety Misr 1 ), were conducted at Tag El-Ezz Agricultural Research Station, Agricultural Research Centre (ARC), Dakahlia Governorate, Egypt during two successive winter seasons of 2016/17 and 2017/18. The experimental area were located at 30 o 95' 7034'' N latitude and 31 o 60' 0219' E longitude. The experiment treatments were included two factors 1) potassium humate (KH) at three levels (i.e. control, 3%, 6% of spraying solutions) and 2) proline (P) at three rates (i. e .control, 50, 100 mgl -1 ). The two factors were layout in a split plot design with three replicates, where the potassium humate and proline treatments were located randomly in the main and sub plots, respectively. The obtained results indicated that addition of potassium humate 6% with proline at 100 mgl -1 gave the highest values of N, P and K % in wheat grains and straw, protein content and also gave the highest grains yield, compared with control treatment, so that the combined treatment of potassium humate 6% with proline 100 mgl -1 was considered as most suitable treatment for obtaining the highest wheat yield under these experimental conditions. In addition to reduce the negative effects of salt stress on wheat plants.

Study the effect of air flow on changing some soil properties and plant nutrition is highly important to increase crop quality and productivity. The pot experiment was carried out focusing on Agric faba bean C.V. Giza 2 in Egyptian alluvial soil (clay) during 2017-18 seasons. Two soil samples with three replicates were taken. The results revealed that hygroscopic water (HW), saturation percentage (SP) and real density (RD) have not affected by air flow, while organic matter (OM), hydraulic conductivity (HC) and bulk density (BD) have remarkable increase with air flow. The available macro and micronutrients concentrations in soil and plant are also discussed where different results have been obtained depending upon type of nutrient.  The total count of bacteria (TCM) is found to be affected with air flow than without aeration techniques. The findings of this study reveal that aeration or air flow promotes healthy levels of soil gases and plays a critical role in plant growth.

Two successful field experiments were carried out during 2020and 2021 growing seasons to evaluate the effect of bio fertilizers; Bacillus amyloliquifaciens (BA), Bacillus megaterium (BM) and cyanobacteria inoculation on the vegetative growth, growth parameters and plant chemical content of Cucurbita pepo (Squash) crop. The study of mixed inoculation with both Bacillus strains, and cyanobacteria was found to improve vegetative growth, plant chemical contents and positive microbial activity in the soil Rhizosphere in comparison to un-inoculated plants. Soil available nutrients (N and K) increased significantly with BA and BM combined with cyanobacteria while available phosphorus gave most increase with BM.
