Seeding method and rate influence on weed suppression in aerobic rice

Yield Parameters and Yield of Aerobic Rice (Oryza sativa) as Influenced by Different Seeding Methods and Weed Control Measures

“…Among the seeding methods the more grain yield was recorded with line sowing (S 2 ) (3161) and was significantly superior over broadcasting (S 1 ) (2366) which might be due to less competition between crop and weeds and high yield attributes recorded with line sowing. Similar results were reported by Anwar et al, (2011), Moorthy and Rao (1991). The grain yield was significantly influenced by the interaction of seeding methods and weed management practices.…”

“…Close observation of data indicated that among seeding methods line sowing produced significantly higher number of panicles m -2 (257.0) compared with broadcasting (234.8) similar results reported by Anwar et al, (2011).…”

“…Among seeding methods higher test weight, longer panicles, more panicle weight were observed with (S 2 ) line sowing (20.8), (17.4) and (1.28) over broadcasting (S 1 ) (18.9), (16.2) and (1.19) respectively, similar results were observed with Anwar et al, (2011). Among weed management practices, significantly higher test weight, longer panicles and more panicle weight were associated with hand weeding T 9 (21.38), (20.1) and (1.43) which was followed by T 6 (21.6), (17.3) and (1.34) respectively., and which in turn on par with T 7 , T 5, T 8 which are significantly superior over other treatments, which might be resulted from weed free environment at the time of panicle production.…”

Effect Of Planting Geometry On Growth Of Rice Varieties

“…Planting geometry of a crop affects the interception of solar radiation, crop canopy coverage, dry matter accumulation and crop growth rate (Anwar et al, 2011). The closer planting geometry causes competition among plants for light, water, and nutrients which consequently slow down growth as well as the grain yield.…”

Effect of Spatial Distribution and Nitrogen Level on Growth Attributes of Hybrid Rice (Oryza sativa L.)

“…Plant space determines solar radiation interception, crop canopy coverage and total dry matter accumulation (Anwar et al, 2011). Also, several studies had shown that the closer planting may cause mutual shading which may direct to intra-specific competition that increases the problems of lodging (Bond et al, 2005), insect pest infestation (Tan et al, 2000) and even rat injuries (Castin and Moody, 1989).…”
