Abstract:

The present investigation was carried out at the experimental farm of Department of Floriculture and Landscape Architecture, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan, HP in the year of 2016-2017 during different season (rainy season and summer season) and pooled data of both the season experiment were taken. The experiment was laid out in randomized block design replicated thrice and with 10 treatments. The treatments comprised of N2 fixer (Azotobacter), PSB (phosphorus solublizing bacteria) PGPR (plant growth promoting rhizobacteria) and AM (Arbuscular mycorrhiza) with the three levels of NPK 70%, 80% and 90% respectively. Pertaining data exhibited growth and flowering parameters like highest plant height (72.48 cm), more leaf area (75.40 cm2), higher plant spread (41.53 cm), more number of flowers per plant (40.34) and longest flowering duration (47.44 days) in plants supplied with Azotobacter + PSB + 70% RDF (T4). With regards to season, plant height, leaf area, plant spread, number of flower per plant and flowering duration recorded to be more (70.76 cm, 78.91 cm2, 42.09 cm, 38.60 and 42.87 days, respectively) during summer season planting as compared to rainy season planting while minimum number of days taken to bud appearance (53.04 days), minimum days taken to first flower opening (65.07 days) were observed with the application of same treatment (T4) during rainy season. Whereas, maximum weight of individual flower (6.12 g) and largest flower diameter (5.85 cm) were recorded with Azotobacter + PSB + 80% RDF (T4) during rainy season. Lowest values of growth and flowering traits were recorded in (T1) control treated plants.
