Three representative and different composts were selected and used in this work a green compost GC, a mixed compost MC and a green coffee compost GCC. The three composts were characterized by means of conventional methods for several chemical and physical properties, including pH, electrical conductivity EC, moisture and ash contents, total organic carbon TOC content, total N content, CN ratio and humic acid-like HAL content. Seeds of slickspot peppergrass were placed in Petri dishes on filter paper, and different tentative germination experiments were made. Germinated seeds were transplanted in glass pots containing fine quartz sand and Nitch nutrient solution. All the germination trials were almost unsuccessful. Correlation of the germination and seedling growth data with chemical and physico-chemical parameters of the composts, HALs and DOMs will be examined, in order to find out the parameters that influence germination and growth of peppergrass.
