| Abstract | Τhe potential use of the aromatic plants Mentha spicata L. (spearmint) and Salvia fruticosa Mill. (sage) as soil amendments was evaluated. For this purpose, tomato seeds were sown in pots that had been filled with composts made from these plants and mixed with soil collected from an organically cultivated tomato field. A 2 × 2 × 4 [two types of fertilizer (synthetic and organic), two types of compost (M. spicata and S. fruticosa) and four compost rates (0%, 2%, 4% and 8%, w/w)] factorial experiment was used; the experiment was conducted twice in a growth chamber and lasted 60 days. At 0, 20, 40 and 60 days, after the establishment of the experiment, the soil bacterial and fungal abundance, the growth of nitrifying bacteria, the number of emerging weeds and the shoot length of tomato plants were measured in all treatments; at the end of the experiment, the above and belowground biomass of tomato plants was also determined. Soil microbial density increased with increasing compost rate of both species; the highest fungal and bacterial densities were recorded at 40 and 60 days, after the establishment of the experiment, respectively. Nitrifying bacteria were present in all treatments and at all sampling times. Both composts had a stimulating effect on tomato growth, which was remarkably pronounced with M. spicata. In contrast, weed emergence was reduced, but only in soils amended with M. spicata. The results suggest that M. spicata compost added at a rate of 4% to 8% is a very promising soil amendment, since it stimulates tomato growth, increases soil bacterial and fungal abundance and inhibits weed emergence. Further research is needed to elucidate the mode of action of M. spicata compost, its effect under field conditions and its possible use in mixed crop, rotational crop or cover crop systems. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
