Studies on the Effect of Integrated Nutrient Management on Growth and Flowering of Chrysanthemum (Dendranthema grandiflorum) Cv. Pusa Shwet

Abstract

The present investigation was conducted in the Experimental Farm, Department of Agriculture, Mata Gujri College, Fatehgarh Sahib, Punjab during year 2023-24 with eight treatments comprising of different doses of integrated nutrients  viz: T1 i.e., Control, T2 i.e., VAM (0.05 g/m2) + NPK (20:10:10 g/m2)T3 i.e., PSB (0.05 g/m2) + NPK (20:10:10 g/m2), T4 i.e., Azospirillum (0.05 g/m2) + NPK (20:10:10 g/m2) ,T5 i.e., VAM + PSB (0.05+0.05 g/m2) + NPK (20:10:10 g/m2), T6 i.e., VAM + Azospirillum (0.05 + 0.05 g/m2) + NPK (20:10:10 g/m2), T7 i.e., Azospirillum + PSB (0.05 + 0.05 g/m2) + NPK (20:10:10 g/m2), T8 i.e., RDF (40:20:20 g/m2), with three replications in randomized block design. The maximum plant height (41.72cm), number of leaves per stem (12.81cm), number of stems per plant (12.29), stem length (15.19cm), diameter of main stem (8.12mm), plant spread (33.13cm2), Leaf length (37.20cm), were recorded in T7 i.e., Azospirillum + PSB (0.05 + 0.05 g/m2) while minimum plant height (28.94cm), number of leaves per stem (8.14), number of stems per plant (6.92), stem length (9.18cm), diameter of main stem (5.59mm), plant spread (17.67cm2), was recorded under T1 i.e., control. T7 i.e., Azospirillum + PSB (0.05 + 0.05 g/m2) shows best results in number of flowers per plant (18.85) While minimum flowering attributes i.e., number of flowers per plant (6.44) was resulted in T1 i.e., control.
