Abstract/ Executive Summary:

An experiment was conducted at the Crop Botany Farm of Bangladesh Agricultural University, Mymensingh, during the period from March to October, 2006 to find out the effect of plant spacing on the growth and yield of Mukhi Kachu. Nine plant spacings viz. 75x 45cm, 75x 35cm, 75x 25cm, 60x 45cm, 60x 35cm, 60x 25cm, 45x 45cm, 45x 35cm and 45x 25cm were used in the study. Plant spacing showed positive influence on the height of main plant, total number of leaves hill^-1, number of leaves of main plant, number of leaves of suckers hill^-1, fresh and dry weight of lamina and leaf sheath, number of suckers, number of corms and cormcls, fresh and dry weight of corm and cormels, yield of corms and cormels. Yields of corms and cormels were increased with the decrease in plant spacing up to 60x 25cm. However, the closest spacing of 45x 25cm produced lower yield probably due to inter plant competition. The highest yield of cormels (20.24 t/ha) was obtained from the spacing of 60x 25cm.

Objectives:

1. The present study was undertaken to investigate the effect of plant spacing on the production of Mukhi Kachu.

Methodology:

The present research work was carried out at Crop Botany Farm of Bangladesh Agricultural University, Mymensingh during the period from March to October, 2006. The cormels of Mukhi Kachu cultivar. Pancho Mukhi used in the experiment were obtained from previous cropping year (2005) from the Kapasia thana under the Gazipur district. The average weight of seed cormel was (20±2) g. The cormels were kept in a room temperature (26±2⁰C) for 15 days before planting. The land for the experiment was opened on 20 February, 2006. The experimental plot was then thoroughly prepared by ploughing and cross ploughing with power tiller followed by laddering to obtain a good tilth. The experiment was laid out in the Randomized Complete Block Design (RCBD) with three replications. The size of each unit plot was 2m x 1.5m. The treatments included different spacing such as 75x 45cm, 75x 35cm, 75x 25cm, 60x 45cm, 60x 35cm, 60x 25cm, 45x 45cm, 45x 35cm and 45x 25cm. The whole experimental plot was first divided into three blocks, each of which was then divided into 9 unit plots. The nine treatment combinations were then assigned randomly to nine unit plots of each block. The whole amount of cowdung was applied at the time of general land preparation and the entire quantity of triple super phosphate was applied during the final land preparation. Urea and muriate of potash were applied as side dressing in two equal installments on 40 and 90 days after final land preparation. Cormels were planted in different spacings as per treatments at 5 to 6 cm soil depth on 11th March, 2006. Weeding was done periodically whenever necessary. Two earthing-up were done throughout the entire growing period. The first earthing-up was done when 1-2 leaves were unfolded and the second earthing-up was done after 60 days from the date of first earthing-up. The height of the main plant, the number of leaves, the number of suckers per hill, the weight of leaf sheath per hill, the fresh and dry weight of lamina per hill, number of corms per hill, number of coromels per hill, weight of the main corms and the secondary corms, fresh and dry weight of cormels per hill was measured at harvest. Yields of corm and cormel were recorded as fresh weight basis. Fresh weight of all parameters were taken immediately after harvest whereas dry weight were taken after sun dried for 48 hours and thereafter oven dried for 72 hours at 80° C. The data for different characters under study were analyzed statistically to find out the significance of treatment effects. Analysis of variance was done by the`F’ (Variance ratio) test. The significance of the differences between means was evaluated by the least significant difference (LSD).

Achievement/Findings:

Yields of corms and cormels were increased with the decrease in plant spacing up to 60x 25cm. However, the closest spacing of 45x 25cm produced lower yield probably due to inter plant competition. The highest yield of cormels (20.24 t/ha) was obtained from the spacing of 60x 25cm.
