A field experiment was carried out to study the effect of bio-inoculants and Gibberellic acid on vegetative growth and flowering of African marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda” at the Main Experiment Station, Department of Floriculture & Landscape, Acharya Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Ayodhya (U.P.) during the years 2019-20 and 2020-21.
The experiment was conducted in Randomized Block Design (Factorial) with 12 treatments replicated thrice to assess the effect Bio-Inoculants and Gibberellic Acid on the Vegetative Growth of African Marigold.
Results reveal that the application of Azotobacter by soil treatment 4L/ha and Gibberellic acid 200 ppm had left a significant response on the growth of marigold. The maximum plant height, primary branches per plant, secondary branches per plant, plant spread, and Plant basal diameter was obtained with the combined application of A3 (Azotobacter by soil treatment 4L/ha) and G4 (Gibberellic acid 200 ppm) whereas the minimum values were recorded in control. The interaction effect of both the treatment was found non-significant.
