EFFECT OF POTTING MEDIA ON GROWTH AND YIELD OF CHRYSANTHEMUM

A field study was conceded to assess the effect of potting media on growth and yield of chrysanthemum at Horticulture Research Centre (HRC), Gazipur, Bangladesh. The experiment was laid out in Randomized Complete Block Design (RCBD) with seven treatments and three replications. It was observed that plant height (54.0 to 66.0 cm); number of leaves per plant (208-240); leaf size (4.5 to 8.5 cm); plant spread (19.0 to 32.0 cm); number of branches (4 to 12); number of flowers (25-40) and stalk length (8.8 to 13.3 cm) varied; respectively in T7 to T3. The days of first flowering varied from 55 to 70 days. The maximum days was recorded in treatment T7 (70 days) whereas the minimum in T3 (55 days) followed by T5 (58 days). The treatment T3 produced the highest weight (5.5 g) of flower stalk per plant and minimum yield (3.0 g) was recorded in T7 of flower stalk per plant. Maximum duration of flowering was observed in cocodust (T3) (45 days) and minimum flowering duration in T7 and T1 (18 and 20 days). Among the seven potting media, T3 (cocodust) showed the highest efficacy and it could be used as media in cultivation of C. indicum production.
