Settings and Design: The experiment was performed to evaluate the organic fertilizers effect on spinach (Spinacia oleracea) properties. Materials and Methods: This included 16 treatments in 4 replications which were laid out in a randomized complete block design. Treatments included compost, horse vermicompost and a compound of sawdust, crushed and noncrushed pomegranate peel and horse manure vermicompost of 8 and 12%. Statistical Analysis Used: After data collection, the MSTAT-C software was used to sort the data. Data was subject to analysis of variance (ANOVA) with SAS software and where significant means where detected, mean separation test was performed using the Duncan's test at the 1% probability level. Results: The results showed that all treatments significantly affected the variables. The treatment including horse manure vermicompost + sawdust + crushed and noncrushed pomegranate peel 8% caused the highest portion of Vitamin C in the plant. The highest amount of organic acid was observed in the crushed pomegranate peel and sawdust 12% vermicompost treatment. The most positive effect on total soluble solid was observed in treatments (horse manure vermicompost, sawdust and noncrushed pomegranate peel 8%) and (horse manure vermicompost, sawdust and crushed and noncrushed pomegranate peel 12%). Conclusions: Treatment (horse manure vermicompost, 8%) resulted in the most length in spinach leaves. It was therefore concluded that the effect of vermicompost treatment was more significant than the compost treatment on the growth of spinach. ER -
