Abstract/ Executive Summary:

Eight exotic year round jackfruit germplasm and three red jackfruit germplasm were studied at the Fruit Research Farm, Joydebpur during 2018-19. Plant height, base girth and number of branches were recorded in August 2018 and in July 2019. The average plant height was observed to be 61.0 cm in 2018 and 191.0 cm in 2019. At the same time, average base girth was recorded to be 4.40 cm in 2018 and 14.85 cm in 2019. Six germplasm were observed to produce male inflorescences from the second week of November, 2018 which was the sign of off-season and year round behaviour. Only male inflorescences were observed from the first year of planting, but no female inflorescence was appeared.

Program Area: Variety and Species

Commodity: Jackfruit

Objectives:

To determine of Exotic Jackfruit Germplasm at the Fruit Research Farm, Joydebpur

Methodology:

An experiment was conducted at the Fruit Research Farm, Horticulture Research Centre, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during 2018-19 to study the growth and development of 8 exotic year round and 3 red jackfruit germplasm of Thailand and Vietnam. Pit was prepared and initially 20 kg cow dung, 400 g TSP, 200 g MoP and 50 g gypsum were incorporated with the upper soil of pit.
