Weed Management in Lentil (Lens culinaris Medic. L.) in North West India

To work out effective weed management in lentil on loamy sand soil experiments were conducted at the Research Farm, Department of Agronomy, Punjab Agricultural University, Ludhiana, during the Rabi seasons of 2009–10, 2010–11 and 2011–12. Oxyfluorfen @ 0.18 kg ha⁻¹, pendimethalin 0.50 kg ha⁻¹ and trifluralin 0.50 kg ha⁻¹, each integrated with one hand weeding at 30 DAS were found the most effective in reducing the population of both broad and narrow leaf weeds and dry weight of weeds and gave maximum weed control efficiency. The integration of either of oxyfluorfen 0.18 kg ha⁻¹, pendimethalin 0.50 kg ha⁻¹ and trifluralin 0.50 kg ha⁻¹ with one hand weeding at 30 DAS and sole application of oxyfluorfen at 0.18 kg ha⁻¹ produced maximum plant height, number of pods per plant and grain yield which were significantly higher than unweeded control. Application of any of these herbicides singly did not provide effective control of weeds.
