Abstract

Sunflower (Helianthus annuus) is an annual species crop for its edible oil and edible fruits used as bird food, as livestock forage as meal or silage plant, and in some industrial applications. Application of Azotobacter chroococcum, Bacillus megaterium, Trichoderma viride as soil application with 100 per cent NPK and Foliar spray of Trichoderma viride has showed maximum germination percentage, increased plant height, number of leaves, stem girth and less number of days to 50 per cent flowering at all the four stages of plant growth viz., 30, 60, 90 DAS and at harvest. Similar trend was also noticed in head diameter, seed yield per hectare, 100 seed weight, and seed volume weight, oil content and residual NPK status of soil. The results of this study has clearly recorded that conjunctive use of Azotobacter chroococcum, B. megaterium and T. viride as soil application and foliar spray of T. viride is advantageous for the growth of Sunflower and to obtain higher crop yields.
