Abstract/ Executive Summary:

A Study on the performance of three exotiv date palm germplasm was conducted in the farmer’s field of Bhaluka, Mymensingh during January to October 2011. Vegetative growth of all the germplasm were good and all the germplasm came into flowering in March and it took about 45 days for fruit set after initiation of flower bud. The line PD Ex 001 performed better than others. Highest yield was recorded from PD Ex 001 (30 kg/Plant) and the lowest yield was obtained from PD Ex 002 (19 kg/plant). The fruit weight was varied from 6.00g (PD Ex 003) to 7.84g (PD Ex 001). The highest TSS was recorded from PD Ex 001 (79%) and lowest from PD Ex 002 (65%). The qualitative fruit characters were different among the lines. The line PD Ex 001 produced cylindrical semi dry fruit of brown clour. On the other hand the lines PD Ex 002 and PD Ex 003 produced ovate elongated and ovate soft fruit of deep brown colour. In respect of edible stage fruit of PD Ex 001 and PD Ex 003 were suitable for Tamar stage (Fully ripen harvest from plant) while the fruit of PD Ex 002 was suitable for the consumption in Khalal stage.

Keywords: Exotic date palm, Physico morphological characteristics

Location: Farmer’s field of Bhaluka, Mymensingh

Start Date: 01-01-2011

End Date: 31-10-2012

Program Area: Variety and Species

Commodity: Fruit

Objectives:

To study the performance of exotic date palm in Bangladesh.
To evaluate, characterized and documented the exotic date palm germplasm.
To developed exotic date palm variety having higher yield and good quality.

Methodology:

The experiment was conducted at the farmers’ orchard at Bhaluka in Mymensingh. The orchard was established in 2001 by transplanting of seedling raised from seed collected from Soudi Arab. Cowdung and TSP were applied during transplanting @ 25 kg and 500 g respectively during planting. The palms were fertilized twice in a year before on set of rainy season and after rainy season with urea and MoP @ 200 g and 100 g in each time respectively. Flood irrigation was given during winter season once in each month. Weeding was done six times in each year. No insecticide and pesticide were used yet. Three plants were evaluated during this study which came into fruit bearing. Data on plant growth and development were taken. The mean and standard deviation were calculated

Achievement/Findings:

The climatic condition of Bangladesh was found suitable for exotic date palm cultivation. Considering plant growth, flowering, fruit size, yield and quality all the germplasm performed better. In respect of edible stage fruit of PD Ex 001 and PD Ex 003 were suitable for Tamar stage (Fully ripen harvest from plant) while the fruit of PD Ex 002 was suitable for the consumption in Khalal stage.
