Growth and flowering responses of Lisianthus to different plant spacing

Abstract

A field experiment was accomplished at the Horticulture farm of Sher-e-Bangla Agricultural University to study the effect of different plant spacing on the growth and flowering of Lisianthus (variety-SAU Blue Nandini). Plant Spacings viz. S1= 30 cm x 15 cm (BARI recommended for Gerbera), S2= 30 cm x 20 cm, S3= 30 cm x 25 cm were used in this experiment arranged in a Randomized Complete Block Design with three replications. Data on different growth and flower yield attribute parameters were taken in which all the treatments showed significant variations. The results showed that applied spacing significantly affected growth and flowering attributes positively. Tallest plants (75.9 cm), the maximum number of leaves (68.7), leaf length (6.0 cm), highest SPAD value (51.0), highest stem length (58.4 cm) and maximum stem diameter (5.3 mm), highest peduncle length (12.6 cm), maximum stem number per plant (6.5), flower number per plant (42.3) was found from (S3) whereas minimum in (S1). The study showed that higher spacing application would be the potential for commercial Lisianthus production among all these.
