Yield improvement of non-puddled transplanted Aman rice as influenced by effective weed control under conservation agricultural systems

Traditional puddled transplanting (PT) can successfully be replaced by strip-tilled non-puddled transplanting (STNT) because it saves energy, fuel, labour and cost of cultivation (Haque et al., 2016; Islam et al., 2012). Moreover, STNT provides better rice yield than the conventional PT (Haque et al., 2016). But heavy weed infestation can cause a significant yield loss in STNT (Zahan et al., 2014). While conservation agriculture (CA) systems highly relies on herbicide for controlling weeds (Muoni et al., 2014), this study was undertaken to find out the effective herbicidal weed control for strip-tilled non-puddled transplanted aman rice that can ensure the optimum grain yield.
