Efficacy of nutritional management on flowering of Anthurium andraeanum cv. Tropical

An experiment was carried out to study the impact of nutritional management on flowering of anthurium under agroshadenet of BTCC LAB, Baramunda, Dept. of Floriculture & Landscaping, OUAT Bhubaneswar with objectives to study the effect of nutrients on flowering of Anthurium cv. Tropical. The potting mixture comprised of substrates like charcoal, coconut husk, mango bark, coconut chops and bricks in equal proportion and pots were placed under agro shadenet structure having 50% shade. The fifteen treatments comprised of substrate application of RDF- Urea: SSP: MOP@ 7.2:4.6:3.0g/plant alone and in combination with Ca as Calcium carbonate (1.6g/plant), Mg as Magnesium sulphate (1.5g/plant), foliar application of Sulphur as Wettable Sulphur (1.5mg/l) and MS Micro (10ml/l). Urea, SSP and MOP were applied to the plants. The experiment was laid out in Completely Randomized Design and replicated thrice. The result of the investigation revealed that substrate application of RDF Urea:SSP: MOP @ 7.2:4.6:3.0 g/plant, Ca as Calcium carbonate (1.6g/plant), Mg as Magnesium sulphate (1.5g/plant) significantly enhanced the floral characters like stalk length (12.83 cm), number of flower per plant /month (2.15), spathe length (8.7cm), spathe breadth (7.16cm), spadix length (4.3cm) and spadix breadth (1.5cm) as compared to other treatments.
