Abstract
An experiment was conducted at the Bangladesh Jute Research Institute (BJRI), Regional Station, Kishoreganj, Bangladesh during July to December 2010 and 2011 to study the effect of spacing and time of de-topping on yield and quality of kenaf seed cv. HC-95 grown under transplanting method. The experiment comprised three plant spacing (viz., 40 cm × 15 cm, 30 cm × 15 cm and 20 cm × 15 cm) and five de-topping (viz., no de-topping, de-topping at transplanting, de-topping at 15, 30 and 45 days after transplanting (DAT) in a Randomized Complete Block Design (RCBD) with three replications. The highest yield of kenaf seed was obtained from planting at 30 cm × 15 cm spacing. The best quality seed in respect to germination and vigour was also obtained from transplanting at 30 cm × 15 cm spacing. The highest seed yield, germination and vigour of seed were obtained for de-topped at 30 DAT. The study concludes that late season kenaf produces highest seed yield with best quality when planted at 30 cm x 15 cm spacing and for de-topping at 30 DAT.

Highlights
Kenaf (Hibiscus cannabinus L.) is a fibre crop belonging to the family Malvaceae
Kenaf is highly profitable crop in Bangladesh. It can give very high yield and cultivation is profitable than jute because it can be produced with lower cost and minimal management practices

Summary
Kenaf (Hibiscus cannabinus L.) is a fibre crop belonging to the family Malvaceae. At present, around 0.08- 0.09 million tons of kenaf is produced in the country from 0.04 million hectares of land (Mostofa, 2012) which required 480 tons of seed. Government and other seed producing organizations in the country are not able to meet up the requirement. The production of quality kenaf seed in the country is very much essential to meet the increasing demand and expand this valuable crop. Kenaf is highly profitable crop in Bangladesh It can give very high yield and cultivation is profitable than jute because it can be produced with lower cost and minimal management practices. The prices of jute and kenaf fibres are almost same, and as consequence, kenaf is expanded to huge areas in char and marginal land of the country. It has multiple uses and its demand is increasing. This can be used as good source of fibre, fuel and it has substantial impact in alleviating environmental degradation
