An experiment was conducted at Farmer’s field, Hagarga village, Kalaburagi district during 2023-24 on effect of spacing and micronutrients on growth and flowering parameters in annual chrysanthemum cv. Bijli (Chrysanthemum coronarium L.). The experiment consists of two factors i.e., four spacings (30 x 15, 30 x 30, 40 x 15 and 40 x 30 cm) and four micronutrient application (Micronutrient mixture @ 0.2, 0.3, 0.4 and 0.5 %) in factorial Randomized Block Design with three replications. The results revealed that significantly maximum plant height (98.05 cm), minimum days to first flower bud initiation and 50 per cent flowering (41.50 and 66.23 days), maximum flower yield per plot and per hectare (8.05 kg and 14.91 t) recorded significantly highest in S₁. Between different concentration of micronutrient applications, M₄ registered significantly highest plant height (102.07 cm), minimum days to first flower bud initiation (44.00 days) and 50 per cent flowering (67.78 days), maximum flower yield per plot (5.89 kg) and per hectare (12.08 t). Hence, the results of present investigation revealed that, planting with closure spacing (S₁) and 0.5 percent micronutrient mixture (M₄) were found to be superior.
