Integrated weed management in spring planted sugarcane (Saccharum officinarum).

摘要

On the basis of 3 years data it is concluded that to keep sugarcane weed free for first 3-4 months, an integrated weed management practice, viz., application of hexazinone (46.8%)+diuron (13.2%) mixture at 1.2 kg/ha, followed by 1 hoeing at 90 days after sowing proved to be the best as it effectively reduced weed intensity, weed dry matter and recorded highest cane yield. The technology also proved economically viable in terms of net returns and B:C ratio.
