ABSTRACT
An experiment was conducted at agronomy field laboratory of the Patuakhali Science and Technology University, Patuakhali to study the effect of sowing method and variety on the yield and yield components of Aus rice (direct-seeded pre-monsoon rice during March-June). Six varieties viz. BR2, BRRI dhan27, BRRI dhan48, Kaliboro, Kalihaita and Tepu and two sowing methods viz. broadcasting and line sowing were used under the tidal ecosystem. Factorial experiment was laid out in a split-plot design with three replications. Results revealed that line sowing gave the highest Leaf Area Index (LAI) (3.89), dry matter plant-1 (31.17 g), total number of tillers hill-1 (4.31), total number of spikelets panicle-1 (102.33), panicle length (21.60 cm), 1000-grain weight (25.33 g), grain yield (3.29 t ha-1), straw yield (6.12 t ha-1) and biological yield (9.41 t ha-1) than the broadcasting method. Among the varieties the highest LAI (5.568), 1000-grain weight (29.73 g), grains panicle-1 (106), grain yield (3.71 t ha-1) and harvest index (44.54%) were recorded from BRRI dhan48. The lowest LAI (2.17), effective tillers hill-1 (3.34), grains panicle-1 (51.17), total spikelets panicle-1 (62.67), grain yield (2.50 t ha-1) and biological yield (7.28 t ha-1) were recorded from Kalihaita. The interaction between sowing method and variety revealed that the highest, grain yield (3.82 t ha-1) was recorded from BRRI dhan27 in line sowing. BRRI dhan48 in line sowing gave the highest LAI (5.66), harvest index (55.45%) and second highest grain yield (3.80 t ha-1). On the other hand, Kalihaita in broadcasting gave the lowest LAI (2.157), grains panicle-1 (6.99), grain yield (2.37 t ha-1) and biological yield (6.61 t ha-1). Results suggested that BRRI dhan48 is suitable in line sowing for higher yield under tidal ecosystem of Patuakhali.
