Abstract/ Executive Summary:

The study was conducted at the Horticultural Farm and Laboratory of Sher-e-Bangla Agricultural University, Bangladesh during the period from February 2012 to March 2013 to study the effect of spacing on growth, yield and storability of mukhikachu cv. Bilashi. The experiment consisted of four different plant spacing S₁ (60 cm × 20 cm); S₂ (60 cm × 30 cm); S₃ (60 cm × 40 cm) and S₄ (60 cm × 50 cm). Maximum individual corm weight was found from S₄ (90.3 g) which was statistically similar with S₃ (89.1 g) whereas minimum from S₁ (42.2 g). Maximum number of sucker per hill (7.9), yield of corm (5.6 ton) and cormel (26.2 ton) per hectare was found from S₃ whereas the lowest from S₁. 60 cm × 40 cm plant spacing was more suitable in consideration of yield contributing characters and yield but had no effect on the storability of cormels of mukhikachu.

Commodity: Aroids

Objectives:

To study the effect of spacing on growth, yield and storability of mukhikachu cv. Bilashi.

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 of four different plant spacing viz. S₁ (60 cm × 20 cm); S₂ (60 cm × 30 cm); S₃ (60 cm × 40 cm) and S₄ (60 cm × 50 cm) 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 t ha^-1), urea (150 kg ha^-1), Triple Super Phosphate (150 kg ha^-1), MP (175 kg ha^-1), gypsum (30 kg ha^-1), zinc sulphate (15 kg ha^-1) and boric acid (5 kg ha^-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. Treatment wise 250 g cormels were stored in room temperature after harvesting. 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 suckers/hill, weight of individual corm, number of cormels/plant, yield of corms/plot, yield of corms/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 spacing (60 cm × 40 cm plant spacing) S₃showed significantly better performance in most of the parameter under study. By maintaining this plant spacing growth and yield of mukhikachu can be increased but storability of cormels might not be significantly affected by plant spacing.
