Abstract/ Executive Summary:

Advanced lines of Olkachu viz. OK-OOl and OK-002 along with a local cultivar were evaluated Joydebpur, Jessor, Pahartali and Khagrachari during March to December 2013. OK-002 ormed good in most of the growth characters followed by OK-DOl. The highest average yield r location (42.99 t/ha) produced by OK-002 and followed by OK-OOl (34.61 t/ha). As per , irement of NSB the experiment need to be continued in the next year.

Keywords: Regional yield trial, Ol kachulines

Location: At Joydebpur, Jessore, Ishwardi, Pahartali and Khagrachari

Start Date: 00-03-2013

End Date: 00-12-2013

Program Area: Variety and Species

Commodity: Aroids

Objectives:

The present investigation was undertaken to release an ol kachu varieties for mass cultivation in Bangladesh

Methodology:

The experiment was conducted at Joydebpur, Jessore, Ishwardi, Pahartali and Khagrachari during kharif season of 2013. The planting dates were 07.04.13, 09.03.13, 13.04.13, 10.03.13 and 23.04.13 at Joydebpur, Jessore, Ishwardi, Pahartali and Khagrachari, respectively. Two advance Olkachu lines OK-OO 1 =Satkhira, OK-002=Madrazi and one local (OK-003) were set in RCB design with 4 replication. The unit plot size was 3m X 3m with spacing of 60cm X 60cm. The crop was fertilized with a dose of 200-125-175 kglha of urea-TSP-MOP, respectively. Half of MOP and full dose of TSP were applied in plot during final land preparation. Rest of MOP and half of urea were top dressed at 60 DAP and the rest half of urea was applied at 100 DAP. Other intercultural operations like weeding, earthing up, irrigation, drainage etc. were done as and when necessary. The crop was harvested in different time in different locations. The harvesting dates were 03.11.13, 10.11.13, 08.11.13, 02.02.14 and 29.02.14, at Joydebpur, Jessore, Ishwardi, Pahartali and Khagrachari, respectively. Data were collected on growth, yield contributing characters and yield and were analyzed statistically

Achievement/Findings:

Plant height at 120 DAP, OK-002 produced the tallest plant over all of the five locations. Dwarf plant produced by local (OK-003). In mean plant height over five locations 50.36 em plant produced by OK-002 and 42.532 ern was in local (Ok-003) . Girth of pseudostem at 120 DAP were varied statistically among the treatment in all locations except Khagrachari. The maximum 9.73 em was recorded in OK-002 at Ishwardi condition. The minimum I. 72 cm was observed in local at Phartoli condition. The average girth of pseudostem was 4.09, 4.32 and 3.80 em in OK-001, OK-002 and local, respectively Number of pseudo stem was varied statistically among the treatment in all the locations. The mean over the locations the range was 2.13cm to 2.39 cm.
