Abstract/ Executive Summary:

A pot experiment was conducted at Patuakhali Science and Technology University, Dumki, Patuakhali during April 2013 to May 2014 to study the survival abilities of 10 Arabian date palm accessions in Bangladesh. The experiment was laid out in a two factors (ten accessions and three pot mixtures) in the Completely Randomized Design (CRD) with three replications. There were significant differences in various traits among the genotypes. The time required for germination was the lowest for Dubai small but the highest for Dabash. The time required the completion of germination of saplings was the least for Deglet Nour (Algeria) and the highest for Marium (Algeria). The highest number of leaves was found in the Deglet Nour (UAE) and the lowest was in Farida. After 12 months, the tallest plant was measured for Dubai small but the shortest was for Deglet Nour(UAE). The highest plant vigour after 12 months was found in Deglet Nour (Saudi), while the lowest was in the Deglet Nour(UAE). Among the three pot mixtures, soil : cowdung=1:1,showed best results for plant height and vigour.

Location: Patuakhali Science and Technology University, Dumki, Patuakhali.

Start Date: 01-04-2013

End Date: 31-05-2014

Program Area: Variety and Species

Commodity: Date

Objectives:

To evaluate the germination capability of seeds of 10 Arabian date palm accessions collected from local and exotic sources;

(ii) To evaluate the survival capacity of saplings of these accession sand finally; and

(iii) To select suitable genotype especially for the saline prone coastal area of Bangladesh.

Methodology:

The seeds of the 10 Arabian date palm accessions used as the study are given in Table 1.

Seeds were soaked with water for 1, 2 and 3 days and incubated in an incubator at 30⁰C. Within 7-11 days seeds got sprouted. Then those sprouted seeds were sown into poly bags (18 cm X 10 cm) at the depth of 1-2 cm.

Table 1. Identities of 10 Arabian date accessions used in the study

Accession no.	Name of the variety	Country of origin
V1	Deglet Nour (UAE)	United Arab Emirates
V2	Deglet Nour (Algeria)	Algeria
V3	Deglet Nour (Saudi)	Saudi Arabia
V4	Borhi	United Arab Emirates
V5	Marium (Algeria)	Algeria
V6	Nagal	Saudi Arabia
V7	Normal	Iraq
V8	Farida	Saudi Arabia
V9	Dabash	United Arab Emirates
V10	Dubai (small)	United Arab Emirates

Three pot mixtures used was as follows- S₁ (Sand: Cowdung = 1:1), S₂ (Soil: Cowdung = 1:1) and S₃ (Sand: Soil: Cowdung = 1:1:1); because date thrives in sand, sandy loam, clay and other heavy soils too (Morton, 1987). After three months saplings were transplanted into pots (10 L) filled with the pot mixture as per experimental design. The experiment was laid out in a factorial Completely Randomized Design (CRD) with three replications, (three pot mixtures and ten genotypes). Thus, there were 90 unit pots.

Data collection and analyses

Data were collected on time required for sprouting, germination percentages, time required for completion of germination, days required for two leaf state; number of leaves, plant height and plant vigour (in 5 scale) after 6 and 12 months.

Achievement/Findings:

From the preliminary observation, it could be concluded that Bangladeshi soil is also appropriate for optimum growth of Arabian date palms and Deglet Nour (Saudi). Marium (Algeria) and Normal were the most promising varieties in term of preliminary performance, while those of the accession no. V₁ (Deglet Nour from United Arab Emirates), V₂ (Deglet Nour from Algeria) and V₁₀ (Dubai small) were unsatisfactory. In case of germination media, soil: cow dung (1:1) was the best as the germinating medium while the other two media was not satisfactory. However, further study is needed to find out the probability and prospect of growing date palms under the climatic conditions of Bangladesh.
