The functional groups found in isolated leaves are responsible for FT-IR peaks that correspond them....

To investigate the antibacterial effects of water and ethanolic extracts henna leaves roselle calyxes against pathogenic bacteria isolated from domestic wastewater. The antimicrobial activity was determined in using agar disc diffusion method. activities (2.5%, 5.0% 10.0% w/v) both were tested one Gram-positive Bacillius subtilis; two Gram-negative Escherichia coli, Pseudomonas aeruginosa human bacteria. Ethanolic had more than extracts. extract highest all organisms, followed with henna....

Environmental stress has a major influence on the growth and quality of medicinal plants. More than half agricultural land worldwide suffers from lack water. In this study, we estimated effect different irrigation intervals growth, yield, essential oil content as well their main compounds lemongrass, Cymbopogon citratus. The objective was to test how much consumption can be lowered without significant impact yield properties. Water deficit led decreases in characteristics including number...

Owing to its hand-picked flower heads and applications in organic farming systems, Egyptian chamomile has a good reputation export markets. This study was carried out evaluate the growth, productivity oil quality of during two successive seasons El-Sharkia, Egypt, at four different locations, which differed greatly salinity soil irrigation water. Salinity did not negatively impact yield or essential contents. The greatest content were obtained under high-salinity conditions. Total 28...

One of the main components sustainable agricultural strategies in crop production is substitution chemical fertilizers with alternatives. This study aimed to examine effects partial replacement mineral bio-stimulants (yeast and/or moringa leaves extract).
