The field experiment was carried out at Regional Research and Technology Transfer Station (OUAT), Semiliguda of Koraput district under Eastern Ghat High Land zone of Odisha during kharif season of 2012 & 2013 to study the effect of topping operation on growth and yield of niger (Guizotia abyssinica). The results revealed that niger cv. Utkal Niger-150 recorded maximum seed yield of 541.4 kg/ha with respect to the varieties and the treatment having topping at capitulla initiation stage (35 DAS approx.) recorded maximum seed yield of 549.7 kg/ha which was at par with the seed yield recorded with no topping operation (543.9 kg/ha) and topping operation at 10 days before capitulla initiation stage (25 DAS approx.) with seed yield of 532.8 kg/ha. No topping recorded the highest net monetary return of Rs.5282/ha and benefit cost ratio of 1.6 followed by topping operation at 10 days before capitulla initiation stage (25 DAS approx.) with net monetary return of Rs.4451/ha and benefit cost ratio of 1.4.
