Abstract/ Executive Summary:

A study was carried out at the Fruit Research Farm of Horticulture Research Centre, BARI, Gazipur during 2018-19 to evaluate the growth, flowering and fruiting behavior of persimmon germplasm. Data on the plant and fruit characteristics, time of flowering, fruit shape and colour, harvesting time and number of fruit per plants and seed characteristics of persimmon germplasm were recorded. The tallest plant (5.00 m) with maximum number of branches (4.0) was recorded in the germplasm DK Joy-002. The shortest plant (3.65 m) with minimum number of branches (3.0) was found in DK Joy-001. Maximum number of fruits (46) per plant was obtained from DK Joy-002. Individual fruit weight was recorded 70 g in DK Joy-001 and 62 g in DK Joy-002. The highest TSS (14.0%) was recorded in the germplasm DK Joy-001.

Location: HRC nursery BARI, Joydebpur, Gazipur, Bangladesh

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Persimmon

Objectives:

To evaluate the performance of the existing persimmon germplasm.

Methodology:

A graft of persimmon plant was collected from Japan and planted at HRC nursery BARI, Joydebpur, Gazipur in 1980. Another germplasm was planted at Fruit Research Farm, BARI, Joydebpur, Gazipur in 1996. The plants were fertilized with cow dung (20 kg), urea (250 g), TSP (250 g) and MoP (150 g) in two equal installments one is before onset of rainy season and another is after rainy season. Besides this dose of fertilizer, the plants were fed with 200 g urea, 250 g TSP, 200 g PM and 100 g boric acid at mid April 2019. Irrigation was given after fertilization in each installment. Irrigations were given at 15 days interval in the dry period (October to February of 2019). Dead and undesired branches were pruned after harvest of fruits in August. Insecticide of Cypermethrion group was sprayed at the time of new vegetative flash (February – March) to control the chaffer beetle infestation. Data on growth, flowering, yield and fruit characteristics and pest and disease reaction were recorded.

Achievement/Findings:

Growth of both the germplasm was satisfactory and maximum yield was harvested from DK-Joy002. The experiment will be continued accommodating more number of non astringent type germplasm. Continuous raining on late March to first week of April may wash out the stigmatic fluid, which resulted in the less bearing of both of germplasm.
