Effect of different media and bio-inoculants on seed germination of Rangpur lime (Citrus limonia Osbeck.)

The present investigation was carried out at Department of Horticulture, College of Agriculture, Badnapur, during the year 2016-2017. The experiment was laid out in Factorial Randomized Block Design with twenty treatment combinations replicated twice. Freshly extracted Rangpur lime seeds were sown into different media with bio-inoculants treatment including control to study their effect on germination. The results of the investigation revealed that, amongst the different media treatments, the medium M1 i.e. Soil: Sand: Vermicompost (2:1:1) recorded earliest germination (12 days) with maximum germination percentage (82.50%) and took minimum days (13.25) to reach 50 per cent germination and whereas under the bio-inoculants treatments, the treatment B3 (Azotobacter) recorded earliest germination (14 days) with maximum germination percentage (82%) and took minimum days (15.80) to reach 50 per cent germination. Interaction effect of different media and bio-inoculants on seed germination showed non-significant differences.
