2018, International Journal of Agriculture Sciences(IJAS)

The present investigation was conducted to study the efficacy of Azotobacter and Phosphate Solubilizing Bacteria on Vegetative and Floral attributes of African marigold (Tagetes erecta L.) cv. Pusa Narangi Gainda under hilly regions of Uttarakhand at College of Horticulture, VCSG UUHF, Bharsar, Pauri Garhwal, Uttarakhand during February to July 2017. The results revealed that application of Azotobacter + PSB + RDF (T8) significantly recorded maximum vegetative attributes like plant spread (63.12 cm), number of primary branches per plant (15.70), number of secondary branches per plant (28.13), number of leaves per plant (442.00) and fresh weight of 30 leaves (33.33g). Floral attributes viz., number of days taken for first flower bud initiation (50.13), number of days taken for first flower opening (68.52), number of days taken for 50% flowering (78.39), flowering duration, (70.89), flower diameter (9.30cm), number of flowers per plant (52.39) and number of flowers per plot (628.72)and quality attributes viz. shelf life (7.73 days),whereas, plants treated with plots Azotobacter+ RDF (T4) showed maximum plant height (94.97 cm), dry weight of 30 leaves (6.07± 0.89) and flower weight (14.10 ±1.25).
