Abstract
A field experiment was conducted on clay soils of Regional Agricultural Research Station, Lam, Guntur during kahif 2006-07, 2007-08 and 2008-09 respectively to find out suitable weed management package for turmeric ( Curcuma longa L.) in coastal districts of Andhra Pradesh. Pre-emergence application of oxyflourfen @ 0.25 kg/ha followed by post-emergence application of quizalofop ethyl @ 0.05 kg/ha and two hand weeding at 60 and 90 days after sowing (DAS) with WCE of 92 % significantly recorded the highest fresh rhizome yield (6.6 t/ha) with B:C ratio of 0.61 and was on par with hand weeding at 30, 60 and 90 DAS, which recorded the highest fresh rhi- zome yield (8.5 t/ha). Uncontrolled weed growth reduced rhizome yield by 80%.
