Abstract/ Executive Summary:

The experiments were conducted to find out the suitable rice varieties for growing in Aus season under standard Agronomic management. An experiment was conducted at Amtoli, Barguna and Muladi, Barisal area in Aus 2012 season. The test varieties were BRRI dhan27 and BRRI dhan48. The experiment was conducted in one farmer field in each location. The treatments were distributed following RCB design with three replications. The tallest plant was observed in BRRI dhan27 over BRRI dhan48 both at Muladi, Barisal and Amtoli, Barguna area. The highest number of panicle number m^-2 and grains panicle^-1 was found in BRRI dhan48 at Muladi. The higher grain yield was observed in BRRI dhan27 than that of BRRI dhan48. However, results obtained at Amtoli, Barguna indicated that most of the parameters showed almost similar trend as observed at Muladi, Barisal except grains per panicle, where BRRI dhan27 showed more grains per panicle than BRRI dhan48 and the test variety BRRI dhan27 also exhibited higher grain yield at this location.

Start Date: 01-04-2012

End Date: 30-09-1012

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

The experiments were conducted to find out the suitable rice varieties for growing in Aus season under standard Agronomic management.

Methodology:

An experiment was conducted at Amtoli, Barguna and Muladi, Barisal area in Aus 2012 season. The test varieties were BRRI dhan27 and BRRI dhan48. The experiment was conducted in one farmer field in each location. The treatments were distributed following RCB design with three replications. Twenty-six-days-old seedlings were transplanted at Muladi, Barisal area and 27-days-old seedlings planted at Amtoli, Barguna at 20 cm × 20 cm spacing. The unit plot size was 5 m × 4 m. The fertilizers were applied urea @ 168 kg ha^-1, TSP 60 kg ha^-1, MOP 45 kg ha^-1, Zypsum 25 kg ha^-1 and ZnSO₄ 5 kg ha^-1. Full dose of TSP, MOP, gypsum and ZnSO₄ were applied during final land preparation. The urea was top dressed at 15 & 30 DAT. Supplementary irrigation, insect and weed control were done as and when necessary. Data on plant height, panicle number, grains per panicle, grain yield and sterility percentage was recorded during harvesting.
