Abstract/ Executive Summary:

In pot planting method, the highest cutting establishment was found in ‘Rooton 3 G’ (10.00) and the lowest were in control (1.00). The highest number (2.67) of tuber was found in ‘Rooton 3 G’ and IBA + NAA (2.67). The lowest number was in control (0.33). The highest number (2.48) and weight (28.87 g) of tuber per Plantlet was found in 16 ppm IBA and 8 pmm NAA nuxture. The highest weight (17.33 g) of tuber per Plantlet was found in ‘Rapid root’

Keywords: Hormone, Potato, Stem Cutting

Location: Gazipur

Start Date: 30-03-2007

End Date: 15-03-2008

Program Area: Crop-Soil-Water Management

Commodity: Potato

Objectives:

To find out the effectiveness of ‘Rooton 3 G’ and ‘Rapid root’ for stem cutting establishment and to compare with the present practiced hormone combination.

Methodology:

Two rooting hormone solution IBA (16 ppm) and NAA mixture of IBA 16 ppm + NAA 8 PPM, and two commercial products “Root on 3 G” and “Rapid root” were taken for evaluation. The top shoot (3-4 cm) from the 25-30 day old potato plant is removed with a sharp knife. Then the cuttings were placed at 1.0 -1.5 cm depth in sand bed or plastic pot containing charcoal media. The bases of the cuttings were dipped in different hormone solutions for 10 minutes before setting in pots /beds. The planted pots/beds are kept in shed condition until root initiation. Irrigation is provided every morning and evening. Two different experiment was set for pot and bed plating and ten cuttings were placed for each treatment. The experimental design was CRD and replicated for 3 times. They variety was Diamant. The cultivation practices are followed by the recommended method of potato production from seed tuber. Data were recorded on percent cuttings established, plant height, number and weight of tuber per plant (g).

Budget: 25,000/=

Total Budget (Tk.) : 25,000/=

Achievement/Findings:

The new product, Rooton 3 G is effective for stem cutting establishment of potato. IBA + NAA mixture or “Rooton 3 G” or “Rapid root” can be used for stem cutting establishment of potato to obtain maximum number and weight of tubers per plantlet but preparation of IBA and NAA mixture is expensive for farmers. Though ‘Rapid root’ had the better performance to obtain maximum number and weight of tubers per plantlet but the product is not available in Bangladesh.
