Abstract/ Executive Summary:

An experiment was conducted at the Horticultural farm of Sher-e-Bangla agricultural University, Bangladesh to find out the optimum cormel size for higher yield of mukhikachu during the period from February 2012 to March 2013. The experiment consisted three different corm size viz. C₁: Small size (5.0-7.5 g); C₂: Medium size (7.5-10.0 g) and C₃: Large size (10.0-12.5 g). Tallest plant (53.7 cm at harvest), maximum number of leaves (4.5 at harvest), foliage coverage (47.3% at harvest), sucker/hill (8.0), weight of individual corm (80.9 g), number of cormels/plant (21.8), yield of corm (2.1 kg/plot), yield of corm (5.9 t/ha), yield of cormels (8.6 kg/plot), yield of cormels (23.9 t/ha) but minimum weight loss (16.7%), rotten cormel (13.5%) was found from C₃ while minimum from C₁.

Keywords: Mukhikachu, Corm size, Growth and yield.

Location: Horticultural Farm and Laboratory, Sher-e-Bangla Agricultural University (SAU), Dhaka, Bangladesh.

Start Date: 00-02-2012

End Date: 00-03-2013

Program Area: Crop-Soil-Water Management

Commodity: Aroids

Objectives:

To find out the proper corm size for better yield of mukhikachu.

Methodology:

The study was conducted at the Horticultural Farm and Laboratory of Sher-e-Bangla Agricultural University (SAU), Dhaka, Bangladesh during the period from February 2012 to March 2013 to study the effect of plant spacing on the growth, yield and storability of mukhikachu. The experiment consisted three different corm size viz. C₁: Small size (5.0-7.5 g); C₂: Medium size (7.5-10.0 g) and C₃: Large size (10.0-12.5 g) followed by Randomized Complete Block Design with three replications. The size of the each plot was 2.0 m × 1.8 m. The distance maintained between two blocks and two plots were 1.0 m and 0.5 m respectively. Corms were sown in the plot with maintaining distance as per treatment. Cormels were planted at a depth of 7-8 cm. Cowdung (15 tha^-1), urea (150 kgha^-1), TSP (150 kgha^-1), MP (175 kgha^-1), gypsum (30 kgha^-1), zinc sulphate (15 kgha^-1) and boric acid (5 kgha^-1) were applied. The entire cowdung, TSP, gypsum, zinc sulphate, boric acid, ½ urea, ½ MP were applied during final land preparation. Rest of the urea and MP were applied in two installments, firstly at 45 DAP (Days after planting) and secondly at 100 DAP (BARI, 2008). Earthing up was done at 60 and 120 days after planting followed by weeding on both sides of rows by taking the soil from the space between the rows by a small spade. After harvesting of mukhikachu cormel treatment wise 250 g cormel were stored in room temperature. In the storage room a polythene sheet was spread and 1 inch thickness sand was applied on the polythene sheet. Treatment wise cormel was placed on the sand and again 1 inch thickness sand was applied above the cormel. Weight loss and number of rotten cormel was counted from the storage cormel at 120 days. Data were collected on plant height, number of leaves/plant, foliar coverage, number of sucker/hill, weight of individual corm, number of cormels/plant, yield of corm/plot, yield of corm/ha, yield of cormels/plot, yield of cormels/ha, weight loss (%), rotten cormel (%). Collected data were statistically analyzed using MSTAT-C Computer Package Program. The significance of difference among treatments means was estimated by LSD test at 1% level of probability.

Achievement/Findings:

The large size cormels produced momentous findings in almost all the parameters. The plants produced were vigorous which resolutely produced good in number and quality of corms and cormels.
