Abstract/ Executive Summary:

Pani kachu shewed positive response to both N application and desuckering. The yield of stolon and rbizome increased gradually as the level of N was increased upto 50kg/ha. Desuckering also resulted in higher yield of stolon and rhizome.

Keywords: Nitrogen application, Yield, Desuckering, Pani kachu

Location: Central Station, Bangladesh Agricultural Research Institute, Joydebpur, Dhaka

Start Date: 03-03-1980

End Date:

Program Area: Crop-Soil-Water Management

Commodity: Aroids

Objectives:

To study the effect of Nitrogen Application and Desuckering on the Yield of Pani Kachu (Colocasia esculenta)

Methodology:

The experiment was conducted at the Central Station of the Bangladesh Agricultural Research Institute, Jdebpur, Dhaka. The soil of the farm belongs to the Grey Terrace group having pH value of 5.6. The experiment was laid out in factorial design with 3 replications. There were 5 different levels of nitrogen namely, 0,12.5, 25, 37.5 and 50 kg/ha. The nitrogen was applied in the form of urea as top dressing in 3 equal instalments, after 30, 55 and 80 days of planting. There were 3 treatments involving desuckering, namely no desuckering, desuckering once and desuckering twice. The first desuckering was done after 60 days of planting and the second desuckering was done after 90 days of planting. The size of a unit plot was 6m x 2m, which accommodated 20 plants. Suckers were planted on 3 March, 1980 and the stolons were harvested at intervals of 10 days, starting after 75 days of planting. The rhizomes were harvested on 3 August, 1980.

Achievement/Findings:

The Pani kachu responded noticeably to the various levels of nitrogen and desuckering. The number of stolon per plant and the yield of stolon per hectare increased significantly with the application of nitrogen. The highest length and diameter of rhizome were obtained with the application of 50 kg N/ha. The dose of 50 kg N/ha gave the highest yield of rhizome (20.46 tons/ha). Desuckering resulted in bigger leaf. Desuckering twice produced the leaves of maximum size. Similarly, the highest yield of stolon (3.61 tons/ha ) resulted from desuckering twice. The longest rhizome (33.37 cm) was obtained from desuckering twice. Desuckering similarly increased the diameter and weight of rhizome.
