Effect of Azospirillum Inoculation on Varied Okra Varieties
Author : Mumtaz Husain and Manoj Kumar
Abstract :
The impact of Azospirillum on seed germination and seedling growth of four okra varieties was studied such as Arka Anamika, Versha Uphar, Selection-151, and Parbati Kranti. Seeds treated with Azospirillum bacterial cultures and placed on agar petri dish for Germination at 24, 48, and 72 hours. Seedling growth was assessed by measuring shoot And root length, as well as Newly fresh and dry weights at 5, 10, and 15 days after sowing. A Control group without treatment was also maintained. Significant increases in seed Germination were observed across all varieties with Azospirillum treatment compared to the control. Selection-151 exhibited 100% germination after 72 hours and showed the highest values for shoot and root length, as well as fresh and dry weights. Conversely, Versha Uphar performed poorly in all growth parameters with Azospirillum treatment. Thus, Inoculating seeds with Azospirillum proved advantageous for both germination percentage and seedling establishment due to promoting robust growth.
