Abstract/ Executive Summary:

An experiment was conducted at orchard of Agricultural Research Station, Pahartali, Khulshi, Chattogram during 2018-2019 to study the effect of day length enhancement during winter season and to produce dragon fruit round the year. The highest number floral buds (24.00) were given by T₂and the lowest (00.00) were control. The highest number of dragon fruits (10) was observed in T₁ treatment. The lowest number of fruit was observed from control treatment. From this experiment it can be said that changing day length affect the fruit set in off season dragon fruit production.

Location: Agricultural Research Station, Pahartali, Khulshi, Chattogram, Bangladesh

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Crop-Soil-Water Management

Commodity: Dragon fruit, Cropping System

Objectives:

To study the effect of day length enhancement during winter season and to produce dragon fruit round the year.

Methodology:

An experiment was conducted at orchard of Agricultural Research Station, Pahartali, Khulshi, Chattogram during 2018-2019. The plants were grown on concrete posts with 1.5 m height and spacing of 2 m between plants and 3 m between rows. Eight-year-old dragon fruit plants were used for this experiment. Eight hours light enhancement was imposed on naturally cultivating dragon fruit plants. Day-length was enhanced by 100 (±5) W incandescent bulbs during the period of 5.00 pm to 01.00 am and 5.00 pm to 11.00 am + 4.00 am to 6.00 am.Two treatments were T₁= 5.00 pm to 01.00 am and T₂= 5.00 pm to 11.00 am + 4.00 am to 6.00 am with T₃= control (no day-length enhancement). The experiment was laid out in randomized complete block design having six replications. Data on different parameter were recorded accordingly.

Achievement/Findings:

The highest number floral buds (24.00) were given by T₂and the lowest (00.00) were control. The highest number of dragon fruits (10) was observed in T₁ treatment. The lowest number of fruit was observed from control treatment. From this experiment it can be said that changing day length affect the fruit set in off season dragon fruit production. From this experiment it can be said that changing day length affect the fruit set in off season dragon fruit production.
