A Research On Influence Of Different Weed Control Methodologies On Various Aspects Of Weed Control As Well As Nutrient Depletion Due To Various Weeds And Weed Control Techniques In The Crop Of Lentil (Lens Culinaris Medik.)

Abstract

A field experiment was conducted at the Crop Research Centre, School of Agriculture, Uttaranchal University, Dehradun, Uttarakhand to observe ‘The efficiency of different weed management practices in Lentil’ during the Rabi season of 2021-22. The experimental design used for the purpose was Randomised Block Design with 3 replications and 8 treatments. The treatments were as Control, 2 hand-weeding, Atrazine (Pre-emergence) @1kg a.i. /ha, Atrazine (PE) + 1 hand-weeding, Pendimethalin (post-emergence) @ 1kg a.i. /ha, Pendimethalin (PE) + 1 hand-weeding, Isoproturon (PoE) @ 1 kg a.i. /ha and Isoproturon (PoE) + 1hand-weeding. Out of the above treatments, Pendimethalin + 1 hand-weeding was most effective in controlling the weeds and attaining higher efficiency of weed control. The treatment of 2 hand-weeding was also equally efficient however it is not practical to be performed in larger areas. The treatment of Two hand-weeding observed the lowest nutrient depletion.
