The research was conducted within a greenhouse setting to explore the impact of various compost tea application rates on the growth of ‘Hazera 395’ tomatoes. Additionally, the study aimed to compare the efficacy of soil-applied compost tea versus foliar application methods, all conducted under greenhouse conditions. Utilizing a split-plot design with three replications, soil and foliar applications were designated as main plots, while six compost tea concentration treatments (v/v) were allocated to sub-main plots. These concentrations included: zero treatment (control), as well as extracts of 1:1, 1:25, 1:50, 1:75, and 1:100 compost to water ratios. Notably, soil-applied compost tea significantly enhanced nitrogen (N) and potassium (K) availability compared to foliar application. Moreover, the 1:25 compost tea extract, whether applied to soil or foliage, notably improved vegetative growth parameters such as stem internode count, plant height, and leaf count per plant. Both soil and foliar application of compost tea resulted in significant increases in yield and average fruit weight. In summary, this research advances scientific knowledge by elucidating the effects of compost tea application rates and methods on tomato growth under controlled greenhouse conditions, offering valuable insights for agricultural practices aimed at improving crop productivity and sustainability.

The medicinal plants of Jordan are under threat due to several factors of habitat perturbation. Some of these factors include ruinous over-harvesting, climate change, competition and invasion. In this study, the authors employed a reliable method for micropropagation and assessment of antimicrobial activity of some important medicinal plants of Jordan. Seeds were surface sterilized and germinated on agar water media, and then shoots were cultured on Murashige and Skoog (MS) medium with the addition of 3% sucrose. In order to generate enough plant material, microshoots were transferred after fourteen days onto hormone free MS medium. Among all studied plants, it was found that the Achellia millefolium and Moring perigrina plants successfully multiplied in vitro containing different 6-benzyl amino purine (BA). For potential antimicrobial activity, the ex vitro (field leaf plants) and in vitro (plantlet) extracts were evaluated against some bacteria strains using ethanolic extracts. Both ex vitro and in vitro plants extracts showed the antimicrobial activity against the microorganism tested. The results from the study suggest that these two plants showed good antimicrobial activity against the different tested bacteria.
