EVALUATION OF THE BIOLOGICAL EFFECT OF DIFFERENT VERMICOMPOST AND PEAT MIXTURES ON ROCKET (ERUCA SATIVA MILL.) SEEDLING PRODUCTION

Alexandru Cristian Grosu, Petruța Mihaela Matei, Narcisa Elena Băbeanu

Abstract: The vermicomposting process can improve the quality of horticultural substrates. The main aim of this work was to evaluate the phytotoxicity and Dickson quality index (DQI) of some vermicomposts used as fertilizers.These vermicomposts were obtained from food scraps digestate mixed with shredded paper waste (DWV) and
vineyard wastes such as grape marc and dry shoots (VWV). These vermicomposts were applied as 3.2% and 5.0% on a commercial peat substrate. When aqueous dilutions (1:10 w/v and 1:20 w/v) were made from these vermicompost substrates, the normalized residual germination index (NRGI) showed low phytotoxicity for both DWV and VWV treatments in the dilution 1:10 (w/v), while in dilution 1:20 (w/v) the NREI showed normal development for both vermicompost treatments (VWV and DWV). The Dickson quality index (DQI) calculated for Eruca sativa Mill. seedlings treated with vermicompost from vineyard wastes (VWV 3.2%) demonstrate positive influence on rocket seedlings compared to untreated peat, with significant differences at p < 0.01.

Key words: vermicompost, grape marc, digestate, rocket.
