PERFORMANCE OF AUS RICE VARIETIES IN NORTHWEST BANGLADESH AMID CLIMATE CHANGE (Pages : 7 - 10)

An experiment was conducted at RDRS Bangladesh farm, Monthana, Rangpur, Bangladesh during April to August 2016 to evaluate the yield performance of six aus rice varieties of Bangladesh viz. BRRI dhan43, BRRI dhan48, BRRI dhan55, BRRI dhan62, BRRI dhan28 (BRRI dhan55 and BRRI dhan28 is a boro recommended and BRRI dhan62 in amon recommended but all are photo-insensitive so those can be cultivated year round and BRRI dhan28 is a late boro which known as Boroaus in northwest area) and Pariza. The experiment was laid out in a randomized complete block design with three replications under rainfed condition by using rain water instead of ground water. Total 1532.2 mm rainfall occurred during the cultivation period (April to July 2016). The entire yield contributing attributes varied significantly among the varieties. The highest plant height (108.11 cm) was observed in BRRI dhan28 and the lowest (93.67 cm) in Pariza. In the variety BRRI dhan55 number of filled grains panicle-1 was found highest (105.44) and the lowest (85.0) was recorded in the variety BRRI dhan48. BRRI dhan48 produced the highest 1000-grain weight (25.3 g) and the lowest (23.73 g) was recorded from the variety Pariza. The highest grain yield (3.42 t ha-1) was obtained from BRRI dhan43 and the lowest grain yield (2.33 t ha-1) was obtained from BRRI dhan28. Among the six aus rice varieties under Northwest condition BRRI dhan43 and BRRI dhan48 are suitable in respect of yield and there are many scope of aus rice cultivation under rainfed condition to reduce ground water use as well as to ensure food security.Download
