Effect of bio fertilizer and organic manure on growth, flowering and yield of Salvia (Salvia Splendens)

Abstract

A field experiment entitled “Effect of bio fertilizer and organic manure on growth flowering and yield of Salvia (Salvia Splendens)” was carried out in Department of Horticulture, National Post Graduate College, Badhalganj, Gorakhpur (U.P.) during the winter season of the year 2019-2020. The experiment was laid out in randomized block design with 12 treatments and 3 replications. Among the all treatments, treatment T8 [Vermi Compost (25%) + Azotobacter (50%) + PSB (25%)] proved to be the best in terms of plant height (23.70 cm), number of leaves (80.08), Plant spread N-S (19.24 cm), Plant spread E-W (33.24 cm), Length of flower spike (15.60 cm), Life cycle of flower spike (17.00 days) and Vase life of cut spike (14.84 days). Whereas T9 [Vermicompost (25%) + Azotobacter (25%) + VAM (50%)] was found best in terms of Days taken to first flower (20.83 days) and Days to 50% flowering (39.83 days), and for the yield related traits T3 [Phosphate Solubilizing Bacteria (PSB)] recorded as best treatment in terms of No. of flower spike per plant (10.33), No. of spike/plot (82.64) and No. of spike/ha (206,000); while the minimum results were recorded with T0 (control).
