Effect of Weeding Regime and Row Direction on Growth and Yield of Rice in Bangladesh

Abstract

Abstract

Weeds are always a disturbing pest in crop field. The success of cultivation mainly depends on proper management of weeds through different approaches. The study was conducted in boro (dry) season during the period from November 2010 to May 2011 to investigate effect of row direction and weeding regime on growth and yield of rice. The experiment was consisted of ten weeding regimes and two row directions. Almost all growth parameters, crop characters and yield parameters were influenced significantly due to weeding regimes and row directions. Weeding at 15 days interval was found to produce the tallest plant (88.70 cm), the greatest number of tiller hill^-1 (14.79) and the longest panicle (23.87 cm) under East-West row direction. The highest amount of total dry matter production (63.88 g) was found from weeding at 15 days interval and East-West row direction at 60 days after transplanting. Grain yield (4.46 t ha^-1) was 130% higher with weeding at 15 days interval over no weeding under East-West row direction. East-West row direction also produced 46% higher straw yield (5.06 t ha^-1) from weeding at 15 days interval over no weeding.
