Abstract/ Executive Summary:

Two advanced lines of Olkachu viz OK-001 and OK-002 along with a local cultivar were evaluated at Joydebpur, Jessor, Pahartali and Khagrachari during March to December 2012. OK-001 performed good in most of the growth characters followed by OK-002. The highest average yield over location (53.96 t/ha) produced by OK-001 and followed by OK-002 (39.72). As per requirement of NSB the experiment need to be continued

Keywords: Aroids, RYT, Olkachu

Location: Jessore, Pahartali, Gazipur and Khagrachari

Start Date: February 2012

End Date: December 2012

Program Area: Variety and Species

Commodity:

Objectives:

1.To select superior line(s) 2. High yielding lines wiil be released as a variety

Methodology:

The experiment was conducted at Joydebpur, Jessore, Pahartali and Khagrachari during kharif season of 2012. The planting dates were 31.04.12, 15.04.12, 29.03.12 and 13.04.12 at Joydebpur, Jessore, Pahartali and Khagrachari, respectively. Two advance Olkachu lines OK-001 = Madrazi OK-002 = Satkhira and one local were set in RCB design with 6-7 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 kg/ha 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 18.12.12, 15.04.12, 29.03.12 and 13.04.12, at Joydebpur, Jessore, Pahartali and Khagrachari, respectively. Data were collected on growth, yield contributing characters and yield and were analyzed statistically.
