Abstract/ Executive Summary:

The field experiment was carried out at TCRC, Bangladesh Agricultural Research Institute, Joydebpur during April 2010 to November 2010 to ascertain the proper spacing and seed size for Mukhikachu production. The treatment consisted of three seed sizes and four spacings. Yield and yield contributing characters were significantly influenced by seed size and spacing. The maximum yield (32.49 t/ha) was obtained when whole corm planted at a spacing of 45 cm × 35cm.

Keywords: Cut Seed Corm, Spacing, Growth, Yield, Mukhikachu

Location: Joydebpur, Gazipur

Start Date: 18-04-2010

End Date: 05-11-2010

Program Area: Crop-Soil-Water Management

Commodity: Aroids

Objectives:

To determine the suitable combination of spacing and seed size for obtaining higher yield of Mukhikachu.

Methodology:

The experiment was carried out at TCRC, BARI, Joydebpur during April 2010 to November 2010. The treatment consisted of three seed size i. e. S1 = ½ cut of corm, S2 = ¼ th cut of corm and S3 = whole corm and four spacing i. e. P1 = 60 cm × 30 cm, P2 = 60 cm × 45 cm, P3 = 45 cm × 45 cm and P4 = 45 cm × 35 cm. The average weight of seed corm was 20-25 g. The seeds were planted on 18 April 2010. The experiment was laid out in factorial randomized complete block design (RCBD) with three replications. The plot size was 3 m × 4.5 m. The crops were fertilized @ 275-180-225 kg/ha of urea-TSP-MOP, respectively with 7 t/ha of cowdung. The full amount of cowdung, TSP and half of MOP was applied at final land preparation and rest half of MOP and one half of urea was applied as top dress at 60 days after planting (DAP) and rest half of urea were top dressed at 90 DAP. All the intercultural operations like weeding, two earthing up, irrigation etc. were done as and when necessary. The crop was harvested in 5 November 2010. Data on growth, yield contributing characters and yield were recorded and analyzed statistically and means were separated by using Duncan’s Multiple Range Test.
