Abstract/ Executive Summary:

An experiment On Panikachu was conducted in the Central Research Station of Bangladesh Agricultural Research Institute in 1983 to observe the effect of time of planting (15 January 15 February and 15 March) and time of harvesting ( 120, 140, 160, 180,200 and 220 days). The January and February plantings were similar but better than the March planting in plant yield, rhizome diameter, rhizome yield/plant, total fresh yield with and without petiole as well as dry yield/ha. A growing period of 220 days was found to be conducive to better yield and yield contributing characters, although it was not significantly different from 180, and 200 days.

Keywords: Panikachu, Growing season, Morphological characters, Yield

Location: Central Research Station of Bangladesh Agricultural Research Institute, Joydebpur.

End Date:

Program Area: Crop-Soil-Water Management

Commodity: Aroids

Objectives:

To study the effect of time of planting, and harvesting of Panikachu

Methodology:

The experiment was conducted at the Central Research Station of Bangladesh Agricultural Research Institute (BARI), Joydebpur. A popular Panikachu cultivar, 'Narkeli Kachu, was used as planting material in this experiment. During the growing period of the crop, the average minimum temperature was 23.85°C and the maximum was 31.7°C. The experimental land was selected in a low-lying area so as to keep the soil desirably watered during the entire growing period. The land was puddled with a power tiller and fertilized at the rate of 10 tons of FYM, 40 kg N as urea, 30 kg P_aO₅ as triple superphosphate and 50 kg K₂O as muriate of potash per hectare. Nitrogen and K₂0 were top dressed in splits, but the entire FYM and P₂0₅ were applied before planting. Suckers were planted on 15 January, 15 February and 15 March and harvesting was started after 120 days and continued up to 220 days at an interval of 20 days. The experiment was laid out in a split- plot design with three replications, date of planting being in the main plots and date of harvesting in the sub-plots. The unit plot size was 6.0m X 2.4m accommodating 24 plants at a spacing of 80 cm x 75 cm. For collecting data, 5 plants were selected from the middle row and data were recorded on height of plant, total number of leaves, number and weight of stolon, length and diameter of rhizome, weight of entire plant with petiole, and weight of rhizome and percentage of dry matter. Besides, yield of entire plant with rhizome per plot were recorded on the basis of which fresh and dry yields per hectare were calculated.

Achievement/Findings:

The January and February plantings were similar but better than the March planting in plant yield, rhizome diameter, rhizome yield/plant, total fresh yield with and without petiole as well as dry yield/ha. A growing period of 220 days was found to be conducive to better yield and yield contributing characters, although it was not significantly different from 180, and 200 days.
