ABSTRACT

 The weeds in lentil are one of the major constraints in obtaining maximum yield. The manual weed control is simply not feasible because it is time consuming and costly. The chemical weed control is the effective method of weed management. A field study was conducted to evaluate pre and post-emergence herbicides for weed control in lentil. The experiment comprised eight treatments including three herbicides, manual weeding and check (no weeding). The yield was higher in manual weeding but in herbicide treatments Isoproturon as pre-emergence @ 2 kg -1 ha produced statistically at par grain yield to that of manual weeding -1 followed by Isoproturon after one month of planting @ 2 kg ha . Both the treatments showed 193.9% and 109.2% yield increase, respectively, over -1 the check. It indicates that Isoproturon @ 2 kg ha can be used pre or postemergence in lentil fields to control the weeds without causing injury to lentil plants.
