To better understand the impact of planting techniques and rice varieties for improved yield in low land areas, a field experiment was conducted at Rajshahi University's Agronomy Field Laboratory from May 2018 to November 2018. The experiment used four rice varieties (Digha, Sadavaula, BRRI Dhan 39, and BINA Dhan-7) typically grown in the Chalan beel regions of Bangladesh. It also used two planting techniques: broadcasting and line sowing. Digha and Sadavaula are two indigenous kinds of deep water rice, and BRRI Dhan 39 and BINA Dhan-7 are two high-yielding types. The result shows that maximum plant height (152.01 cm), number of tillers (10.82), panicle length (21.16cm), fill grain (78.79), grain yield (6.708), straw yield (7.484) and biological yield (13.45) was obtained from line sowing method (M2). Within the rice varieties, BRRI Dhan 39 shows greater performance as it contributes maximum no of tiller/m2 (187.93), panicle length (22.02), effective tiller (144.64), grain yield (4.66), straw yield (11.16) and biological yield (15.81). Greater results for flooded rice types came from Digha, which had more tillers per square meter (87.11), panicle length (19.93), effective tillers (70.75), grain yield (2.21), straw yield (8.75), and biological yield (10.96) than Sadavaula. The findings of this study show that line sowing, as opposed to the more conventional broadcasting strategy, can significantly increase rice yield for both high-yielding (BRRI Dhan 39 and BINA Dhan-7) and locally grown flooded rice types (Digha and Sadavaula). Therefore, farmers of the area can be recommended to adopt the line sowing method rather than the broadcasting method, which can significantly boost grain production by 11.45 %.
