Abstract/ Executive Summary:

Six entries viz. BR7587-2B-3, BR7181-3B-16, BR7182-2B-4-HR24, BR7182-2B-1-2-HR4, BR7182-2B-1-2-HR6 and BR7182-2B-1-2-HR25 performed similar in respect of yield with BRRI dhan42 and BRRI dhan43 and were selected for further trial.

Keywords: Aus, Rice, SYT

Location: BRRI, Gazipur

Start Date: 15-04-2011

End Date: 15-07-2011

Program Area: Variety and Species

Commodity: Rice

Objectives:

Initial yield evaluation of advance lines in a replicated trial.

Methodology:

Eight genotypes were evaluated under SYT against the standard check varieties BRRI dhan42 and BRRI dhan43 in 5m X 10 rows plot. Line sowing was done 25cm apart. Seeding was done in April. The field lay out was RCB design with three replicates.Fertilizer doses were 60: 40: 40 kg NPK/ha and P and K were applied at the time of land preparation. Nitrogen was applied at three equal splits at 10 days after transplanting, maximum tillering and PI stages. Gypsum and ZnSO₄ @ 100 and 10 kg/ha were applied during land preparation.
