Effect of Bulb Cutting and Pot Medium on Propagation of Hippeastrum (Hippeastrum hybridum Hort.)

Experiments were conducted at the horticulture research farm ofhorticulture department, bangabandhu sheikh mujibur rahman agriculturaluniversity (bsmrau), salna, gazipur during december, 2007 to may, 2009to investigate the effect of bulb cutting and potting media on propagation ofhippeastrum. the bulb cutting significantly influenced all the parametersexcept days required to first leaf emergence and leaf breadth at 60 dap. leafnumber at 60 dap, leaf length at 60 and 100 dap, number of plant persection of bulb and number of bulb per pot were found to be significantly increasedupto second treatment and then gradually decreased with the increaseof bulb cutting. the highest number (2.20) of plant per section of bulb,bulblets (2.20) per section of bulb were obtained from 4 sections/bulb whilediameter (20.74 mm) of bulb and combined weight (57.65 g) of bulb andplant were maximum at treatment 2 sections/bulb. potting media also showedsignificant influence on all studied parameters. the maximum number (2.04)of plant per section of bulb and bulblets (2.04) per section of bulb wererevealed at potting media containing only compost while the potting mediacontained sand, soil and compost at equal amount produced the biggest sizeof bulblets (20.07 mm) and maximum weight (44.75 g) of bulb and plantcombinedly. however, the combined effect of t2 x p3 produced the maximumnumber (2.60) of plant and bulblets per section of bulb while the biggest size(23.05 mm) of bulblets and the highest yield (68.66 g) of bulb and plantswere obtained in t1 x p4.
