Abstract/ Executive Summary:

In order to find out the suitable cutting length and time of cutting for the successful propagation of dragon fruit the study was carried outat the research field of Regional Horticulture Research Station, Bangladesh Agricultural Research Institute, Shibpur, Narsingdi during October 2017 to April 2019 following RCBD design with 3 replications. The experiment consisted of three different stem cutting lengths i.e. 10, 20and 30cm and sevenmonths of cutting operationstarted from October, 2017 to April, 2018. In case of days to bud break, the shortest period (62 days) was required by the cutting length of 30 cm, while the longest period (72.90 days) was recorded in the cutting length of 10 cm.The longest new shoots (12.50 cm) was recorded in the cuttings of 30 cm length after 30 days of cutting operations as against minimum (8.48 cm) in the cuttings of 10 cm length. Those were longest (42.40 cm) in the cuttings of 30 cm length after 90 days of cutting operations as against minimum (24.55 cm) in the cuttings of 10 cm length. The widest new shoots (1.30 cm) was recorded in the cuttings of 20 cm length after 30 days of cutting operations as against minimum (1.25 cm) in the cuttings of 10 cm length. The longest roots were also found in 30 cm cutting (11.32 cm) after 30 days of cutting operations as against minimum (10.21 cm) in the cuttings of 10 cm length.

Program Area: Crop-Soil-Water Management

Commodity: Dragon fruit

Objectives:

To find out the effect of time and length of cutting in dragon fruit.

Methodology:

The experiment was carried out at Regional Horticulture Research Station, BARI Shibpur, Narsingdi, from September 2017 to July 2019. It consisted of three length of cutting viz., 10 cm, 20 cm and 30 cm, and six months of cutting at one month interval since October 2017 to August 2018. The two factor experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Thus, there were (6×3) 18 treatment combinations. Twenty cuttings were prepared in each replication. A total number of 1080 (18×3×20) cuttings were prepared in the first week of October, 2017 to August, 2018. Cuttings were prepared from mature stem with deep green color not less than 6 months old and cuttings were placed in 8 x 10 inch size poly bag filled with 50% well decomposed cowdung and 50 % sandy loam soil. The cutting was done on the same day of stem collection in each month with a sharp knife. The prepared cuttings were kept under partial shade made by shade net. Data in respect of days to bud break, per cent success (30 DAG), survivability (60 DAG and 90 DAG), shoot length, shoot breadth, root length per cutting and number of shoots per cutting at 30, 60 and 90 DAC were recorded and analyzed statistically.

Achievement/Findings:

The study revealed that irrespective of time of operation cutting length is important for dragon fruit propagation. The longer cuttings showed superiority over shorter cuttings. The cutting prepared with 30 cm length performed better followed by cuttings of 20 cm length in all the growth parameters. But considering number of propagule 20 cm length is suitable. Under this experiment October 2017 to August 2018 operation perform similar results. On the other hand, the cuttings are to be planted in the field for its further performance up to yield then it may be possible to recommend a suitable cutting length and time of cuttings for its effective multiplication.
