Popis: A study was conducted during the year 2018-2020 to find out a suitable potting media and foliar concoction to increase the growth, yield and quality of Dracaena reflexa ‘Variegata’ as cut foliage. The experiment was laid out in CRBD with 13 treatments and three replications. The various treatments significantly influenced the growth, yield and quality attributes of dracaena. Among the different treatments, T12 (sand + vermicompost + red earth+ coir compost+ FYM+ burned rice husk (0.5:0.5:0.5:0.5:0.5:0.5 v/v) as potting media + foliar concoction spray of1%90:90:90 NPK fertilizer + 0.4% FeSO4 + 0.2% MgSO4 + 0.4 % ZnSO4 + 0.2% boron + 0.3% copper + 0.1 % molybdenum + 0.2% manganese + 0.1% cobalt + 0.5% sea weed extract + 250 ppm brassinosteroid at monthly interval) was found to be the best in growth and yield attributes such as plant height (63.4 cm), plant spread (192.4cm¬2), leaves per plant (45.9), leaf length (57.8 cm), leaf width(6.1 cm),leaf area (300.1 cm2), relative growth rate ( 0.07cm day-1), chlorophyll content (17.2 SPAD value), root length (53.8 cm), single leaf weight (22.2 g), shoot fresh weight per plant (717.2 g), root fresh weight per plant (386.2 g), total plant fresh weight (1103.4 g), dry matter production (441.3 g) and leaf yield per plant 36.2 on 270 days after planting. Quality characters like longevity of the leaves in the plant (47.4 days) and visual scoring (9.8), freshness index (88.4), colour index (89), vase life without pulsing(9.9 days) and vase life with pulsing(18.8 days) of the cut foliage of the dracaena were also noted high in T12. Control (T13) recorded the minimum in growth and yield attributes of dracaena such as plant height (33.8 cm), plant spread (85.2cm¬2), leaves per plant (25.6), leaf length (36.1 cm), leaf width (2.1 cm), leaf area (82.8cm2), relative growth rate ( 0.03 cm day-1), chlorophyll content (10.6 SPAD value), root length (28.4 cm), single leaf weight (13.9 g), shoot fresh weight per plant (258.7 g), root fresh weight per plant (139.3 g), total plant fresh weight (398.1 g), dry matter production (159.3 g) and leaf yield per plant (15.6) on 270 DAP, while the quality characters like longevity of the leaves in the plant (35.9 days) and visual scoring (5.6), freshness index (68.4), colour index (69.8), vase life without pulsing (3.8 days) and vase life with pulsing (8.9 days) of the cut foliage of the dracaena were recorded the least.
