Abstract:
The bio inoculants plays a crucial role in reducing the inorganic fertilizer application and increasing the flowers quality and yield besides maintaining soil fertility. With this background, an experiment “Effect Of Bio inoculants with Graded Levels of potassium on flower quality and yield of Chrysanthemum (Chrysanthemum morifolium Ramat.) Under Protected Condition” was conducted at the department of Horticulture, College of Agriculture, Shivamogga during 2021-22. Ten treatments were replicated thrice in Randomized Complete Block Design. The observations were recorded on various flower quality and yield parameters. Among all treatments T₇ (100% N & P+ 75% K + KSB+ KSF) recorded highest individual flower weight (6.36 g), flower diameter (6.69 cm), shelf life (7.17 days), vase life (12.00 days), number of flowers per plant (77.93), flower yield per plant (360.60 g), per m² (4.16 kg) and per poly house (2.6 t/560 m²), number of suckers per plant (7.21), per m² (68.11) and per polyhouse (28607.6). While, lowest was recorded under control. Hence, it is concluded that application of 75 per cent potassium and 100 per cent nitrogen and phosphorous along with bio inoculants is most effective in enhancing the flower quality and yield characters of chrysanthemum.
