Abstract
In order to study the effects of biological, organic and chemical fertilizers on yield and yield components in anisum a field experiment was carried out in the agricultural research field of Yasouj University in 2013, as a randomized complete block design with three replications. Treatments were concluded: Pure vermicompost (0, 5, 10 ton.ha-1) and bio fertilizers Azotobacter (Barvar-1), biological phosphorus (Barvar-2) and mixed of Barvar-1and Barvar-2, chemical nitrogen, bio fertilizers of nano and mixing treatments of vermicompost 2.5, 5, 7.5 ton. ha-1 with biological fertilizers Barvar-1, 2 and mixing of Barvar-1, 2. Results showed that the maximum height (48.63 cm), number of lateral branches (12.43) and umbels per plant (22.86) was obtained by applying 10 ton. ha-1 vermicompost. Also, maximum of grain yield (595.90 kg.h-1) was obtained by applying 10 ton.ha-1 vermicompost while it did not show significant difference with treatment 7.5 ton.ha-1 vermicompost with Barvar-1,2. and minimum of these traits was obtained from control. According to the results of this study showed that application of bio-fertilizers has a significant role in improving qualitative and quantitative yield of medicinal plant anise and we can introduce treatment 7.5 ton.ha-1 vermicompost with Barvar-1,2 as a situated for 10 ton.ha-1 vermicompost from an economical standpoint.
