Effect of Biological, Organic and Chemical Fertilizers on Yield and Yield Components of Anise (Pimpinella anisum L.)

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.
