In this experiment was investigated the potential of Vermicompost as one of the substrate constituents on yield indexes of three strawberry cultivars. For this, were used from four substrates consisted of (0%, 5%, 15% and 25%) vermicompost and three cultivars (Camarosa, Mrak and Selva). The measured traits consisted of diameter of crown, number of inflorescence, fruit length, mean of fruit weight, fruit number and Yield. The results of this experiment indicated that application of vermicompost in substrate improved indexes of yield. The highest of diameter of crown, fruit length and yield were obtained in interaction of Mrak and S2 (19.45 mm, 4.47 cm and 264.143 g respectively). The interaction of Selva and S3 had more fruit number (26.63) than other treatments. Selva cultivar in S4 had the highest of mean of fruit weight (12.33g) also Mrak in S4 had more number of inflorescence (7) than other treatments. Camarosa in S1 had lower fruit length (2.66 cm) and mean of fruit weight (8.27 g) than other treatments also Selva in this substrate had the lowest of yield (140.79 g). The lowest of inflorescence number was observed in interaction of Camarosa and S3. Selva in S4 had the lowest of new diameter crown (13.47 mm) and fruit number (13.34 g).
