Integrated weed management in dry-seeded rice
2014

The present study revealed that weeds cause a rice yield loss of about 90% in dry-seeded rice and the integrated approach to control weeds based on PE application of pendimethalin 1.0 kg/ha fb POE bispyribac-sodium 25 g/ha + ready-mix chlorimuron + metsulfuron 4 g/ha 30 DAS fb one HW 60 DAS was found to be best with WCE of 82%. Increase in rice seed rate from 10 to 32.5 kg/ha resulted in decrease in weed density and weed biomass but the rice yield increase beyond 17.5 kg/ha seed rate was non-significant. Therefore, rice seed rate of 17.5 kg/ha was found optimum for DSR, however it needs further investigation and confirmation.
