A split-plot designed experiment having three replications was conducted under the Department of Agronomy, Bangladesh Agricultural university, Mymensingh during boro season of 2000-2001 to evaluate the influence of planting pattern on the yield and yield attributes of boro rice varieties. Two modern varieties of boro rice [BINA dhan6 and BRRI dhan29) were transplanted in twelve planting patterns [four single rows viz. 25 cm x 20 cm, 25 cm x17.5cm, 25 cm x 15cm, 25 cm x 12.5cm and eight paired rows viz. (25 cm + 15cm) x 20 cm, (25 cm + 15 cm) x 17.5cm, (25 cm + 15 cm) x 15cm, (25 cm + 15 cm) x 12.5cm, (35 cm + 15cm) x 20 cm, (35 cm + 15 cm) x 17.5cm, (35 cm + 15 cm) x 15cm, (35 cm + 15 cm) x 12.5cm]. It was found that, varieties were identical in respect of yield and most of the yield components. Planting pattern significantly influenced the yield and yield attributes. Generally, paired row planting and closer spacing produced higher yield. The highest grain yield (7.16 t ha-1) was obtained from (35cm + 15cm) x 12.5cm pattern, which was comparable to those of (35cm + 15cm) x 15cm and 25cm x 12.5cm patterns. Grain yield was the lowest (6.20 t ha-1) in 25cm x 20cm pattern. Yield and yield components did not vary significantly due to the interaction of variety and planting pattern.
