Abstract/ Executive Summary:

The experiment was carried out at TCRC, Joydebpur during February to September 2010. The treatments comprised of four age group of suckers viz. one month old (A1), two months old (A2). three months old (A3) and four months old (A4) and four spacing viz. 60 cm × 45 cm (S1), 60 cm × 60 cm (S2), 75 cm × 45 cm (S3) and 75 cm × 60 cm (S4). Both the factors significantly influenced growth, yield contributing characters and yield of Panikachu. Two to four months old sucker produced significantly similar number and weight of stolon per plant and yield per hectare in combination with the spacing of 60cm × 45cm.

Start Date: 06-02-2010

End Date: 06-09-2010

Program Area: Crop-Soil-Water Management

Commodity: Aroids

Objectives:

To find out the effect of age of sucker and plant spacing for optimum yield of Panikachu.

Methodology:

The experiment was carried out at TCRC, Joydebpur during February to September 2010. The treatments comprised of four age group of suckers viz. one month old (A1), two months old (A2). three months old (A3) and four months old (A4) and four spacing viz. 60 cm × 45 cm (S1), 60 cm × 60 cm (S2), 75 cm × 45 cm (S3) and 75 cm × 60 cm (S4). The sixteen treatments combination was laid out in a factorial randomized complete block design with three replications. The unit plot size was 3 cm × 3.6 cm. The plot was fertilized with a dose of 275-180-225 kg/ha of Urea-TSP-MOP, respectively with 7 t/ha of cowdung. Half of MOP and full dose of TSP and cowdung were applied in the plot at final land preparation. Rest of MOP and half of urea were topdressed at 60 DAP and the rest half of urea was applied at 100 DAP. The variety used was Latiraj. The crop was planted on 6th February 2010. Other intercultural operations like weeding, irrigation were done as and when necessary. Data on growth, yield component and yield were recorded and were analyzed statistically and means were separated by Duncan's Multiple Range Test.
