Abstract
This study aimed to investigate the interaction between bacterial bio-inoculation by Bacillus megaterium and vermicompost and three phosphate rock fertilizer (0, 100, and 200) kg.ha−1 on the growth and yield of sunflower, Halianthus annuus L. A field experiment was conducted in the fall season of 2020 in the field of silt clay loamy soil. The results showed that inoculation with Bacillus and Vermicompost, individually or together, led to a significant increase in (plant height, leaf area, chlorophyll, and total yield) traits compared to the control treatment. The highest mean was obtained with biological and organic inoculation and phosphate rock fertilizer at the level (100) kg.ha−1 valued at (134.3, 7250, 48.70, and 2808) for the studied indicators, respectively, compared to the comparison treatment.
