A field experiment entitled “Effect of integrated Weed management on pearl millet [Pennisetum glaucum (L.) R. Br. emend Stuntz]”was conducted at Agricultural farm, Suresh GyanVihar University, Jagatpura, Jaipur, Rajasthan in Kharif 2018. The experiment consisted of nine weed management treatments involving three pre-emergence herbicides (Alachlor, Atrazine and Oxyflourfen) in randomized block design with three replications. Among the treatments, 2 Hand weedings (HW) at 20 and 40 DAS(T2) attained higher grain, stover and biological yield (1987, 4935 and 6922 kg ha-1) over other treatments. In case of earhead length and harvest index, Atrazine @ 750g ha-1(PE) + 1 HW at 20 DAS (T6) recorded higher with 8.48g and 28.77% respectively. In case of economics, 2 HW at 20 and 40 DAS (T2) attained highest gross returns ( 49064 ha-1) and Atrazine @ 750g ha-1(PE) + 1 HW at 20 DAS (T6) attained higher net returns and BCR with ( 23332 ha-1) and (1.91) respectively. Among all the yield attributes i.e. ear head length, test weight, grain yield, stover yield, biological yield and harvest index (20.5, 6.10, 863, 2836, 3698 and 23.33, respectively) attained the lowest values and economics i.e. net returns and BCR (2717 and 1.12, respectively) attained the lowest values.
