tailieunhanh - Effect of tillage and weed management practices on weed dynamics and productivity in maize (Zea mays)-wheat (Triticum aestivum) system

An investigation was carried out at Sher-e-Kashmir University of Agriculture Science and Technology of Jammu during 2013-14 and 2014-15, to assess the influence of 4 tillage systems and 3 weed-control practices on weed dynamics and productivity in maize-wheat cropping sequence. In maize, grain yield of maize was statistically at par in continuous conventional tillage (CT-CT) in both maize and wheat and conventional tillage in maize and zero tillage in wheat (CT-ZT). Different tillage treatments did not influence on weed density, weed biomass, plant growth characters, grain and straw yields of wheat in maizewheat cropping sequence. Amongst the weed-control practices, 2 hand weedings which was at par with atrazine (1 kg/ha) in maize and metribuzin (200 g/ha) at par with two hand weedings in wheat which was significantly reduced weed density, weed biomass and recorded significantly higher maize and wheat grain and straw yields than weedy check. | Effect of tillage and weed management practices on weed dynamics and productivity in maize Zea mays -wheat Triticum aestivum system
