The present investigation entitled “Impact of Biofertilizers on Growth Performance of African marigold var. Pusa Bahar (Tagetes erecta L.)” under the Horticulture Research Cum Instructional Farm, was conducted during December 2024-March 2025 at the Department of Floriculture and Landscape Architecture College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur. This experiment was carried out to understand how different biofertilizers and their combinations influence the vegetative growth of African marigold (Tagetes erecta L.) cv. Pusa Bahar. Ten treatment combinations involving Azotobacter, Azospirillum, PSB, KSB and their combinations were tested under a randomized block design. Among all the treatments, the combination of Azotobacter, PSB and KSB (T₇) performed the best resulting in the tallest plants height, the highest number of branches, the widest plant spread and the longest roots length by 90 days after transplanting. The findings clearly show that using a combination of biofertilizers can significantly enhance the vegetative growth of marigold plants.
